How to Decode the Trane Model Number

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.

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.
