Number of employees 7000 Rheem, Ruud, Raypak, Prostock Website Rheem Manufacturing Company is an American privately held manufacturer that produces residential and commercial and, as well as (HVAC) equipment. The company also produces and sells products under the Ruud brand name. It is a subsidiary of Paloma Industries. What became Rheem started in 1925 as a supplier of packaging to the, and is currently headquartered in in the. The company is one of the largest manufacturers of both water heating and HVAC equipment in the United States, and also produces and markets products in, and. Rheem Bennett at Deer Hollow Farm at in California The company is named for its founders, brothers and. They were the sons of (1862–1919), former president who led the construction of a for the company in.

Example: a Carrier Compressor/Condenser Serial# 1389E54894 on a compressor unit. Air conditioning equipment age from serial number for the example above, the equipment was made after 1980. The first four digits of the serial number are week and year of manufacture, in this case, week 13 of 1989.

The brothers initially began manufacturing galvanized steel drums in 1925 as a co-partnership with Pacific Galvanizing Company in. A third brother, William 'W.K.' Rheem, helped finance the company at its start.

The Rheem Manufacturing Company was subsequently organized on January 22, 1930, buying out Pacific Galvanizing. Rheem also acquired the Republic Steel package company, which also had a plant in Richmond. Republic Steel made boilers and tanks, which allowed Rheem to enter the business of water heating. The company acquired the John Wood Manufacturing Company of California, which produced automatic gas storage water heaters, in 1931.

The company expanded overseas to Australia in 1936, building a plant in. The Australian operation began making steel, including drums, in 1937 and water heaters in 1939.

In 1941, the company became the largest manufacturer of automatic water heaters in the United States. During, much of the company's efforts went towards wartime production, including building ships and aircraft parts. In 1954, Rheem brought the introduction of ', which coated the interior of a water heater tank with porcelain to extend the life of the tank. One of the most significant events came in 1956 with the introduction of 'Rheemaire' central air conditioning and heater systems for homes.

This eventually became one of the company's primary business areas. In 1959, Rheem purchased the Ruud Manufacturing Company.

Beginning in August 1970, Rheem began producing and units for residential applications, based in. In 1983, Rheem introduced the Richmond Water Heaters brand to the market, aimed at and. In 1984, Rheem was acquired by Pace Industries, Inc. The company discontinued containers in 1985, ending a 60-year run making steel drums and other containers. In the same year, the company acquired Raypak, Inc., which expanded the business into swimming pool heaters as well as commercial boilers. In 1988 Rheem was acquired by Paloma Industries, Ltd., a privately held Japanese company with headquarters in Nagoya, Japan, which wished to expand globally.

Rheem was the first residential HVAC company to begin using throughout their lineup in 1994, and all air conditioners and heat pumps continue to use. The company was also first to introduce a 14 remote condensing unit in 1997. In 1998, the company began supplying the with a line of branded water heaters. In 2009, Rheem and Ruud were the first to sell a Hybrid Heat Pump Water Heater, which was more than twice as efficient as similar electric water heaters. Also in the same year, Rheem and Ruud central air conditioners were reported to have the fewest percentage of units requiring repair among all major HVAC brands according to. Rheem's market share of the market had ranged had been as high as 16% in the 1980s and had dropped to about 11% by 2000.

By 2008, a report by the ranked the firm as fifth in the U.S. In the central air conditioner and market with a 12% market share (behind UTC/ with 27%, both /Amana and American Standard/ with 14% and with 12%), while in the residential gas furnace market as of 2008, the company was also ranked fifth with a 12% market share (behind Carrier with 32%, Goodman with 15%, and both Lennox and Trane with 13%). History of Ruud Ruud was founded by (1854–1932), a immigrant who lived in.

He developed the first automatic storage tank gas-fired water heater, which went into production in 1889. Ruud worked for (1846–1914), but eventually bought the rights to produce the product he invented and formed his own company in 1897. In 1913, Ruud merged and absorbed the Humphrey Company of which also manufactured water heaters.

The Humphrey Company had a large manufacturing operation in Kalamazoo, which Ruud continued to operate and expand. In 1954, Ruud moved all operations from Pittsburgh to Kalamazoo where they were headquartered until the purchase by Rheem. Current products In North America, Rheem and Ruud both manufacture and sell a full line of heating and cooling products for residential and commercial applications, including up to 98.7% gas furnaces, oil fired furnaces, up to 20 SEER air conditioners, heat pumps, package units, and products such as media filters, and. In many additional countries around the world, the companies sell numerous types of water heating equipment, including gas fired tank storage and tankless water heaters, high-efficiency condensing water heaters, hybrid heat pump water heaters, and solar water heaters under the Rheem, Ruud, Richmond, Paloma, Solahart, Splendid, and brands. Swimming pool-related products include gas fired and heat pump heaters sold under the Rheem and Raypak brands. Protech replacement parts for HVAC systems are sold through the PROSTOCK retail program. In December 2013, Rheem acquired -based Heat Transfer Products Group (HTPG).

HTPG, a standalone company, produces the Russell, Witt, ColdZone and Kramer commercial brands. In 2015, Rheem won the top spot in the Water Heaters category for its brand familiarity by the Builder magazine. Former divisions Rheem Califone manufactured A/V equipment under the Rheem, Califone, and Roberts brands commonly used in schools and institutions, including, as well as. Rheem and Ruud also sold re-branded residential beginning in 2007. However, as of March 2, 2013, the companies no longer listed backup generators on their respective websites.

HVAC data tag decoding: This article explains and translates all of the data found on information tags and stickers used on air conditioning and heat pump equipment. This article series answers most questions about air conditioning systems.

This article provides help in decoding air conditioner, boiler, furnace, heat pump, water heater data tags and determining the age, model, or specifications of that equipment. Find and read the data tag on air conditioners or heat pumps to determine Air conditioner BTUs, Tons, Age: decoded on data tags. Air conditioner electrical requirements & refrigerant needs.

Air conditioner cooling capacity coded in model numbers. Air conditioner and heat pump manufacturer's information; serial number gives A/C age. A/C DATA TAGS - Air conditioner & heat pump data tags de-coded Here we explain the meaning of each of the data names and contents of typical air conditioner system data tags.

We include examples of how to make use of the data to estimate equipment age, capacity, and even its condition. (Not all of the terms we define below will appear on all equipment or motor tags.) The photo at page top shows the main data sticker from a 1997 split system air conditioning compressor/condenser unit.

HVACR Air Conditioning & Heat Pump Equipment Data Tags & Decoding Tips. or MisReading Letters & Numerals on Old HVAC Equipment Data Tabs. stickers on air conditioners and heat pumps The photo shown here is for a conventional (non-split) residential air conditioning compressor unit.

Unless it has been painted-over or lost, on most air conditioners and heat pumps, a metal, foil, or plastic tag or data sticker is usually affixed to the outdoor air conditioner or heat pump compressor/condenser housing. Depending on the age and equipment manufacturer the format and content of data on this tag varies, but typically the tag will allow you to discover some or all of the considerable amount of data listed here:. Manufacturer: The air conditioning equipment manufacturer. Sketch at left on guessing the size of an air conditioner system is compliments of.

As we cite at, Carson Dunlop also provide a Technical Reference Guide with extensive details that aid in decoding HVAC equipment serial numbers and data tags. Model Number, Serial Number, and Cooling Capacity: sometimes cooling capacity is coded into the model number but on most newer units including the Sanyo compressor shown here, cooling capacity is stated explicitly. On older equipment the BTUH cooling capacity may be encoded in the model numbers.

Discusses how to read the cooling capacity in BTUH or tons from air conditioning or heat pump tags. The serial number of modern HVAC equipment encodes the year and month of manufacture - thus the age of the equipment is shown. For equipment where the month and year of manufacture is not stated in plain English, provides a Technical Reference Guide manual that decodes that data. Voltage or VAC for the compressor and separately for the blower fan. In addition to specifying voltage, the cycles (50HZ or 60HZ) and current phases (typically one phase for residential equipment) may be specified.

Branch Circuit Selection Current- BCSC: recommended for determining the required size of the branch circuit conductors (wiring) supplying the equipment. Locked Rotor Amperage - LRA specifies the maximum current that the motor will draw when the motor's rotor is unable to move locked (or under any other condition). NEC Table 430-152-A.

LRA on an air conditioning compressor describes the amperage drawn by the motor briefly during motor startup. Locked rotor amperage is also called inrush current. Because it takes a lot of energy (torque) to get the still parts of an electric motor turning, LRA will always be higher than the current used to keep the motor turning once it has started (FLA or RLA). This is particularly true if the motor has an additional load (resistance to turning) at startup, such as trying to start an air conditioning compressor against refrigerant head pressure inside the compressor unit.

The LRA of electric motors is 700% - 850% of rated current of the motor (or in some sources 5 to 7 times greater than RLA or FLA - a lot. The motor's circuit breaker, especially on an air conditioning system which can draw high initial amps (LRA) will be sized to protect the electrical wiring of the motor circuit, but the breaker also will be chosen to tolerate a brief, high initial current draw to avoid nuisance tripping. In other words, the inrush current, because it is brief, does not need to figure in the selection of the wire sizing when wiring or fusing the motor, except to avoid nuisance tripping. Grundig sonoclock 410 manual arts. The relationship between the LRA and full load amperage (FLA) varies depending on the design of the electric motor being rated.

Motors built to NEMA standards are assigned codes A through H. Each letter can be translated into multiplier x FLA to give LRA. To assist in avoiding nuisance tripping during compressor startup when high current is drawn momentarily, A/C compressor circuit breakers may be permitted to be one size larger than the circuit breaker required by the wire size itself. LRA also affects the choice of the electric motor starter. Finally, an air conditioner motor will also draw its LRA current if the motor is frozen or stuck or has bad bearings - which we hope will quickly trip the circuit breaker or blow the circuit fuse.

Thanks to for requesting clarification of LRA. Minimum Circuit Ampacity - MCA: MCA can be used to determine the required size of branch circuit conductors (wiring and also control switches) supplying the equipment. For example, using NEC Table 310-16 in the 60 degree column as required in 110-14. However some experts recommend using BCSC. Using the 'minimum permitted' sized wire rather than the optimum-size to a compressor may save a few dollars at installation but may increase system operating costs and it may be less safe than using a larger conductor. Maximum Fuse or HACR type Breaker: specifies the maximum overcurrent protection or MOP to be used to protect the equipment. The permitted ampacity of the equipment electrical circuit protection (fuse or circuit breaker amps) expressed as MOP or Maximum Overcurrent Protection.

If MOP is specified, the breaker or fuse protecting the equipment should match this number. A hermetic compressor draws varying amounts of current as its internal pressure changes during operation. Current draw is higher when starting the motor, and highest if the motor is starting against its highest back pressure such as when a unit is turned off and then back on in the middle of operation. Because fusing an air conditioning compressor at the minimum level can result in blown fuses or tripped breakers during these intervals of heavy current draw during compressor startup, compressors are either protected by a slow-blow fuse or a somewhat larger than minimum circuit breaker. On some older equipment MOP is not specified.

Only in the case that MOP is not specified can the overcurrent protection required be determined by the alternative means: RLA OR BCSC whichever is greater x 175%, or if the compressor keeps tripping that device or blowing that fuse, RLA x 225% might be used. The National Electrical Code (NEC) specifies the degree to which a breaker or fuse may exceed the RLA. Rated Load Amperage or Running Load Amperage - RLA, also called Rated Load Current or RLC on some equipment. This is the manufacturer's anticipated load during normal usage, that is, the current drawn when the motor is running normally. RLA is usually similar to FLA in amount.

Typically RLA is about about 64% of the maximum load current. See NEC section 440-2. We sometimes can guess the size (tons of cooling capacity) of an air conditioning compressor by dividing the RLA number by 6, 7, or 8. For example a compressor RLA of 21 amps may be about 3 tons of cooling capacity (21/7).

For more accurate means of determining air conditioner cooling capacity by several means including decoding the data tag, see. In air conditioning systems, typically a motor provides about one horsepower (HP) per ton of cooling capacity.

Full Load Amperage - FLA full load motor current draw, level at which the motor can be operated without damage. FLA is similar to RLA in amount. The FLA amperage is the current the motor will draw when the motor is loaded up to its rated horsepower. If an electric motor is running at less than its rated horsepower it will draw less than its FLA current. If an electric motor is trying to run at more than its rated horsepower, it will draw more than its FLA current. A technician can measure the actual motor amperage (current draw) and compare it to the FLA to quickly tell if a motor is overloaded - in the case of air conditioning a running current draw above FLA may mean that the compressor is near its end of life. Maximum Continuous Current - MCC not usually supplied, this is the most current that the compressor can draw without being damaged.

Typically about 150% of RLA. BTUH Cooling Capacity: The A/C system cooling capacity, either explicitly stated in thousands of BTU's (British Thermal Units) per hour (BTUH) or implicitly given by other data, or coded in the unit's model number.

Water Heater Age Info

The month and year of manufacture, possibly also encoded in the unit serial number. Since the typical life of an A/C compressor is about ten years, one would like to know the probable age of the equipment. EER The Energy Efficiency Ratio of cooling equipment is basically the amount of electricity you consume to obtain a given amount of cooling ability. It's expressed as (KW per hour of electricity used) / Thousand BTUs - this number is probably not going to be found on the equipment itself but may be in its documentation.

You will usually find this data in the bright yellow EnergyGuide sticker that is more often on a side of the equipment rather than encoded in the equipment's own data tag. Details are at Photo courtesy, Galow Homes, Poughkeepsie, New York. Refrigerant type is shown somewhere on every air conditioner, heat pump, or other cooling compressors. The tag shown here notes that the system uses the now obsolete R22 refrigerant. Voltage - the voltage at which the motor is intended to be operated. Motors can normally operate fine at voltages within 10% of the rated voltage level on the data plate. Month and year of manufacture is shown either explicitly as on the Sanyo compressor data tag shown here or this data may be encoded in the unit's serial number.

Provides a manual that decodes more of that data so that you can know the age of the compressor or air handler. That is, the date of its manufacture, not the date of its installation. The installation date of air conditioning equipment may be recorded on a service company's data tag, on receipts, or even inked inside of the steel cabinet of the equipment. Modified, damaged, or torn air conditioning equipment information data tags can make age, capacity, and repair of any equipment more difficult. For the air conditioning compressor unit shown here, all we know is that the manufacturer was Singer. Model numbers and serial number appear to have been cut away from the data tag. Sometimes when equipment data labels are removed or obscured a building buyer or a home inspector may raise a concern that the unit installed was different than that which the was ordered or that it is of questionable origin.

On rare occasion that might be the case. But, a member of member of Refrigeration Service Engineers Society (RSES), informs us that during the 1980's HVAC equipment manufacturers used a type of label which lacked UV resistance, faded, cracked, and eventually peeled away from the equipment, making equipment identification and ordering of replacement parts difficult.

Baker wrote (October 2008) that in the 1980's 'the HVAC compressor label's protective mylar surface was damaged by the printing of the model and serial numbers and the electrical data which allowed the UV from the sun to destroy those areas. Upon discovering that they did not stand up to weather, most manufacturers started putting a second label inside the electrical compartment. Eventually better labels were designed, but some of the better manufacturers still put a second label in the unit.' Where a data tag or label on equipment is damaged or missing, check further for more label data including inside the unit's enclosure. Service technicians may have written the model and serial number data in indelible marker, or the manufacturer may have provided a second data label inside the unit - check HVAC equipment with lost or damaged labels to see if you can find that data elsewhere. You may also find equipment identification details in the installation and service manuals for the equipment if those have been kept in the building. Look around the indoor equipment for those documents.

What we can say from the label in the photograph above is that by 2007 when the photo was taken by an ASHI inspector, this particular equipment was at least 23 years old - older than its usual anticipated life expectancy: the on air conditioners was dropped in 1984.

Examples of HVAC Data Tag Decoding & Identification Questions Reader Question: age of a GE air condenser unit Could you help us determine the age of a General Electric central air condenser. Model TA36H1F01 S/N 205100925 This unit appears to be extremely old, but would appreciate any help you can give me. John 6/1/12 Reply: John, Carson Dunlop's Technical Reference Guide has several pages of GE equipment data decoding information, including the observation that beginning in 1944 GE coded the age in the last three digits of the serial number, with the year in the third from last position.

But the GE serial number codes on air conditioners & heat pumps used letters (N-Z = months Jan-Dec) and Year A-Y = 1944-1964, then repeated). Your serial number does not conform to the known codes for General Electric air conditioners.

GE used letters not digits for month and year as I explained above. Is it possible you are mis-reading a letter 'Z' as a numeric '2' or a P or R as a '9' and an 'S' as a '5'? Examples of troubles reading old fuzzy or partly obscured serial numbers or model numbers on HVAC equipment are in our article just above. So if your 2 and 5 are really SS the unit could be as old as May 1959 or perhaps more likely, as recent as 1980.

Send us a sharp focused photo of the entire label if you can and I'll comment further. The Model Number you provided indicates in the two digits following the TA (TA36) 36,000 BTU/h GE no longer makes A/C units - heat pumps were sold to Trane, Canada. Reader Question: age & data tag decoding for Command Aire equipment I am looking to replace a 30+ year old cooling/heating wall convector from a New York high-rise apartment unit. Attached is the current unit in operation, and there a total of four (4) located in separate spaces within the unit. Click to enlarge any image Can you please tell me if you know what kind of a unit this is from the poor quality photo (Command-Air(?)), and if there are modern replacements I can look into that possibly can be controlled from a wall plate control next to a light switch (for example). 8/21/2014 Reply: I'm not what I'm looking at in your photo. But some basic information about wall convector units used for heating and/or cooling is at Typically in a high rise apartment the energy source for heating and cooling will be piped from a common building source.

You'll want to know what your building supplies before thinking about replacing the equipment. Reader Follow-up: The photo was a poor shot of the model label sent by the contractor currently remodeling the apartment. The units are enclosed within a built-in wooden lacquer cabinet, similar to the attached photos show. I was trying to make out the unit name, and I believe it is an early 80’s Command-Aire model, about 62” wide by 12” deep. I’ve also attached a stand-alone model, with the controls on top beneath the grill. I’m not sure about the building supply details yet, since I have not received information from the contractor, but I’m just trying to find a comparably model to replace this unit(s).

I believe the overall size and top diffuser gives me a head start to look into a Trane Type AK model, just to start comparing. Reply: Command Aire brand was later bought by Trane - so when you know what type and model you've got installed that'd be a place to start looking for a compatible replacement. When you have a clear image of the unit's data tag you'll see brand, model, serial number that will decode into just what is installed. There's little point in looking for equipment and prices before you know what kind of equipment works with your buiding's infrastructure. Command Aire Data Tag BTUh Capacity Decoding For example, Command Aire included heat pumps (which you may not have) SWPR 261 thru 611 water source heatpumps.

(Jan 30, 2014) Kevin said: I'm trying to find the SEER rating on my Carrier condenser. Is it supposed to be on the data tag somewhere? Reply: Good question, Kevin, thanks. No we do not generally see the SEER rating encoded nor explicit on an HVAC equipment data tag. Rather it is in the product literature. I THINK that a reason for this is that the net SEER rating for a given air conditioner or heat pump depends on how a combination of components operates together while certain individual components might be used in more than one set-up.

Example: Carrier's Infinity Split System air conditioners are rated by the company at SEER 16.5 (Model 24ANB6) to 21 (Model 24ANB1) BUT for some manufacturers there is a clue to SEER right in the model number. The Infinity Model 24ANB1 is designated with MODEL NAME INFINITY21 while the Infinity Model 24ANB6, rated at a seer of 16.5 is designated with MODEL NAME INFINITY16. You can for this series only roughly approximate SEER by noting the model name. For example within the Infinity product line by Carrier, two Infinity Models designated INFINITY17 are rated at SEER 18.

Adding honesty to SEER ratings, companies typically state in the product literature 'Up to SEER nn' recognizing that the actual energy efficiency in practice and in specific installations will vary.
