Transport refrigeration protects temperature-sensitive cargo, so its compressor must be identified from the refrigeration unit rather than the truck chassis alone. This category serves refrigeration parts distributors, refrigerated-fleet operators and importers sourcing aftermarket compressor replacements for engine-driven mobile systems.
The reviewed supplier range includes TM16 and TM21-style configurations for refrigerated vehicles, plus 507 and 7H15 records identified for R404a applications. Buyers can use the focused TM Series path when the original unit carries that family identification; other refrigeration compressors remain searchable from this broader application range.
Record the refrigeration-unit brand, model and serial information before searching by compressor appearance. The same truck make can carry different refrigeration packages, and the same body can be transferred to another chassis. Chassis make and engine are supporting details, not a substitute for the unit data plate.
Every number on the old compressor should also be captured. A compressor family can be shared across applications while its drive, mount and head layout changes. If a label is damaged, use clear photographs and measurements to rebuild the identification record.
The TM, 507 and 7H15 refrigeration entries reviewed in the supplier catalog are marked R404a. That distinguishes them from many cab A/C records marked R134a and from a separate R1234yf reference elsewhere in the truck catalog. Still, an R404a marking alone does not confirm the correct unit.
Check the refrigeration-system specification, oil requirement and service procedure for the individual unit. Do not transfer a compressor between refrigerant systems based only on a compatible-looking body or mounting pattern. Refrigerant work should be performed by qualified personnel under applicable requirements.
The reviewed refrigeration range contains both 12V and 24V clutch configurations. TM16 and TM21-style units also show different V-belt and multi-rib pulleys, pulley diameters and mounting arrangements. These variations can affect electrical operation, belt alignment and hose routing.
For an accurate comparison, measure the pulley and mount, identify the connector and photograph the ports. If a bracket, idler or engine-drive kit has been changed, note that modification in the inquiry.
Send the refrigeration-unit data plate, old compressor label, refrigerant, clutch voltage and every public part reference. Add compressor family, pulley style, groove count, diameter, mounting layout, connector and port direction. Include the refrigerated-vehicle application as supporting context.
Wholesale requests should separate each technical version and quantity. State the destination and whether the order supports service inventory or a defined fleet repair program. Commercial quotation follows the technical cross-check; uncertain interchange claims are not carried forward.
It serves the cargo refrigeration circuit, which has its own unit identity, refrigerant and operating requirements.
The supplier catalog includes TM16, TM21, 507 and 7H15-style refrigeration configurations.
No. Start with the refrigeration-unit data plate and original compressor; the chassis information is secondary.
The reviewed records contain 12V and 24V versions, so voltage must be specified for every inquiry.
No. Family, displacement, drive, mount, ports and the unit manufacturer's requirements must also agree.
Provide installed photographs and dimensions of the current bracket and belt path so the change can be considered during review.
Provide the unit data plate and complete compressor configuration for each requested replacement. Elecdurauto will review the available aftermarket transport refrigeration compressor range and organize the quotation by refrigerant, voltage and mechanical fit.
