TM21 / TM-21 24V A2 145 mm configuration
24V refrigerated trucks requiring higher-capacity TM21 R404a service
Transport refrigeration equipment requiring a 24V TM21 assembly with an A2 145 mm clutch
| Quantity: | |
|---|---|
The 24V A2 TM21 is a complete higher-capacity compressor for refrigerated commercial equipment specified with R404a and a 145 mm clutch. Elecdura positions this heavy-duty compressor as an aftermarket replacement for professional A/C specialists, distributors and importers. The exact application-specific build and real heavy-duty compressor image stay together from first enquiry through repeat purchase.
Multiple opened supplier pages recognize a 24V TM21 two-groove application-specific build, providing a practical buying vocabulary for global refrigeration accounts. For this line, the commercial goal is a stable item identity for wholesale account quotation, refrigerated-refrigeration fleet maintenance and service inventory. The page keeps the decision points visible without reading like a service manual or promising fitment from a family name alone.

| Compressor model | TM21 |
| Application family | 24V refrigerated trucks requiring higher-capacity TM21 R404a service |
| Voltage | 24V |
| Pulley | A2, 145 mm |
| Refrigerant | R404a |
| Lubricant reference | Confirm the refrigeration-unit oil specification before commissioning |
| Mounting | Ear-mount TM21 family; confirm bracket span |
| Head and ports | O-ring head connection; confirm orientation from the original unit |
| Rotation | Clockwise |
This item should never be merged with the 12V A2 unit: both use the same TM21 family and clutch size, but the electrical system is different. Check the clutch from a straight front fitment photo rather than estimating from an angled image, then verify the electrical rating and rear connection.
A shared TM21 body does not make every compressor interchangeable. Keep 24V, A2, 145 mm, ear-mount tm21 family; confirm bracket span and o-ring head connection; confirm orientation from the original unit on one account quotation line so belt path, connector position or hose layout cannot be hidden by a familiar casting.
Multiple opened supplier pages recognize a 24V TM21 two-groove application-specific build, providing a practical buying vocabulary for global refrigeration accounts. References such as TM21; TM-21 improve search coverage because fleets, A/C specialists and importers may name the same enquiry differently. They support lookup but do not merge unrelated physical versions.
A/C specialist codes, barcode labels and local-language carton descriptions can be added while the underlying TM21 24V A2 145 mm identity remains on the packing and picking records. This preserves the information needed for a correct repeat account order.
The pages vary on head orientation, groove notation and refrigerant, so the specified 145 mm R404a build remains the sales truth. A reliable first-account order file includes the original label, front clutch view, electrical connector, mounting side and rear head or manifold view. Any conflict should be clarified before price and delivery are finalized.
For Transport refrigeration equipment requiring a 24V TM21 assembly with an A2 145 mm clutch, use equipment information as supporting context rather than the only selection rule. Previous repairs, regional packages and changed belt systems can alter the installed compressor. Elecdura therefore reviews the supplied heavy-duty compressor identity as one complete assembly.
Read the 24V marking, measure 145 mm, count two grooves and save a rear-head view before service inventory allocation. Keep the carton label, A/C specialist item code and purchase reference traceable to incoming photos. Freight damage, missing caps, a bent clutch face or a different rear connection should be isolated before the compressor reaches service inventory.
A practical receiving check verifies the complete assembly, 24V clutch, A2, 145 mm drive, ear-mount tm21 family; confirm bracket span and protected o-ring head connection; confirm orientation from the original unit. The purpose is service inventory accuracy, not refrigeration-system diagnosis at goods-in.
This heavy-duty compressor is designed for distributors consolidating 24V refrigerated-refrigeration fleet compressor demand without losing application-specific build detail. Elecdura can support neutral packaging, OEM labels or qualified ODM presentation for repeat demand. Customer item codes may be used while the exact compressor application-specific build remains on internal picking records.
The standard commercial reference is 50–100 pcs MOQ, a 7–15 day indicative lead time after confirmation and an 18-month warranty under agreed sales terms. Mixed-compressor orders should list every voltage, pulley and refrigerant separately. Bulk RFQ planning is strongest when forecast quantity and destination arrive early.
Confirm 24V, the A2, 145 mm clutch, ear-mount tm21 family; confirm bracket span and o-ring head connection; confirm orientation from the original unit against the removed compressor. Send front, connector, mounting-side and rear-head connection photographs with the account request. The TM21 family name alone is not enough because several electrical, belt and head versions can circulate in the transport refrigeration market.
Yes. The offer is for a complete heavy-duty air-conditioning or transport-refrigeration compressor assembly with clutch, not a loose pulley, coil, valve, housing or repair kit. External brackets, hose manifolds and wiring adapters fitted to the vehicle are not automatically included, so those items should be identified separately when the original system uses them.
No. These references help a sales team locate the enquiry, but they are not universal interchange permission. Compare voltage, clutch profile and diameter, mount, connector and rear ports with the actual unit. This prevents a familiar TM21 casting from sending a visually similar but incompatible compressor into service inventory.
Send quantity, destination, target delivery window, packaging request and A/C specialist item code together with the original reference and clear unit views. For 24V refrigerated trucks requiring higher-capacity TM21 R404a service, add the refrigeration-unit make, vehicle or trailer model and equipment serial information when available. That context supports a heavy-duty compressor-specific account quotation without turning the page into an installation manual.
Yes. Keep every compressor line separate by model, 24V rating, A2, 145 mm description, refrigerant and image. Mixed cartons should preserve distinct labels so service-parts hub staff can receive and replenish the correct application-specific build without relying on the housing shape. Elecdura can review a multi-line list before packaging is finalized.
Elecdura supports aftermarket replacement, wholesale, distributor, importer, refrigerated-refrigeration fleet and private-label enquiries. The normal commercial reference is 50–100 pcs MOQ, a 7–15 day indicative lead time after account order confirmation and an 18-month warranty under agreed sales terms. Final terms depend on quantity, destination, packaging and the confirmed physical application-specific build.
Send quantity, destination, required delivery window and packaging request together with original-unit photographs. Include the refrigeration-unit make, vehicle or trailer model and available equipment serial data so the response addresses the real buying case.
Elecdura will review the defined 24V TM21 A2, 145 mm R404a complete compressor and return a wholesale account quotation for distributor, importer, refrigeration fleet or private-label demand. Physical conflicts will be clarified before an account order advances, protecting service inventory accuracy and repeat-account order consistency.
