A Trane Model Number is used to breakdown or differentiate one product in a series from another. Serial numbers are commonly used in many different types of trane product. Letters are sometimes used along with numbers in the coding.
There is no standard format for how the letters and numbers are used. trane heating and air conditioning companies are free to decide how they want to use the package unit model number.
Examples of Trane Model Number
The Trane model is #TCD120C40CCA. TC: Package Cooling, Electric Heat D: Downflow 120: 10 Tons, Standard Efficiency C: Major Design Sequence 4: 460/60/3 0: ? (a description is not listed) C: Downflow Economizer and Oversize Motor C: Minor Design Sequence A: Service Digit (i don’t know exactly what this means)
Trane RTU model # SXHEC9040E76AD8D3D01GGNRTX S= Self Contained X= DX cooling,Extended Casing H= Single Zone E= 5th Developement sequence C90= 90 Tons 4= 460/60/3 XL 0= No Heat E= Design Sequence 7= 100% Exhaust w/ statitrac & 15 hp motor 6= Ex fan Drive 600 RPM A= Throw away filters D= Supply Fan HP 40 ( 2-20HP) 8= Supply Fan Drive 800 RPM D= !00% Economizer 3= VAV ( SA temp Control w/ IG Vanes) D= BAYSENS014 O= Standard Ambient Control 1= UL Approval
Trane Tonnage from Model Number
TTP018—1-1/2ton TTP024—2 ton TTP030—2 1/2 yon TTP036—3 ton TTP042—3 1/2 ton TTP048—4 ton
Example of Trane Model Identification
TWE030C140b0 TW – split component heat pump compatable E – Electric furnace (like they said, heat strips are added in the field, could be anything from 10kw to 25 kw) 0 – Brazed refrigeration connection 30 is 2.5 ton like you mentioned C – Major development sequence C is standard system, E would be VS motor, P would be high eff system 1 – 220-230/1/60 (electric rating) 4 – Accurtron flow control check valve 0 – Standard insulation B – Minor design sequence (means nothing other than to the facotory) 0 – Service digit (they change these as they do “improvements” on thier stuff)
Trane model number nomenclature split into several segments. Each segment will have assigned a number of letters and digits. Trane uses their model number to identify its use in the HVAC system.
How to Decode
- First letter: The model number starts with 4. This number represents the type of refrigerant the unit uses. 2 stands for R-22 and 4 stands for R410A.
- Second letter. T stands for Trane.
- The next 3 letter represents the product type. W stands for split heat pump and T stands for split cooling. The third letter equals the product family. Z = leadership – 2 stage, X = leadership, R = replacement/retail, B = basic, A = light commercial.
- The fifth number is for unit’s Seasonal Energy Efficiency Ratio. A single number represents the SEER: 0 = 10, 1 = 11, 2 = 12, 3 = 13, 4 = 14, 5 = 15, 6 = 16, 7 = 17, 8 = 18, 9 = 19.
- The six letter. Zero indicates the system’s connections are brazed or soldered.
- The seven and eight number indicate tonnage. How many BTUs the unit produces in thousands. For example: 36 = 36,000 BTUs.
- The nine letter represents the age. Any type of major modifications done to the system since it was originally manufactured explained here. Click here for more information on how to know the age of trane from serial number.
- Number ten indicates the power supply voltage. 1 = 200-230/1/60 or 208-230/1/60, 3 = 200-230/3/60, 4 = 460/3/60.
- The position eleven, twelve and thirteen. These numbers represent any secondary function.
- Position fourteen stands for minor design modifications
- The last letter is the unit part’s identifier code.
The Trane Model Identification Number of a product is often featured prominently on the packaging of said product. On the physical product itself, the model number is most commonly found on the front, rear or bottom of the product or in the manual pdf.
Decoding the Trane model number need patience and accuracy, focus on each segments and you’ll break the code quickly. If you have any problem, please contact your local dealer or Trane sales office.
