TM21 / TM-21 12V A2 145 mm configuration
Refrigerated trucks requiring higher-capacity TM21 R404a service
Transport refrigeration equipment requiring a 12V TM21 assembly with an A2 145 mm clutch
| Quantity: | |
|---|---|
This TM21 complete compressor pairs a 12V coil with a 145 mm two-groove clutch for higher-capacity transport refrigeration service using R404a. Elecdura positions this complete unit as an aftermarket replacement for professional commercial-vehicle buyers, distributors and importers. The exact defined version and real complete unit image stay together from first enquiry through repeat purchase.
Opened pages show this defined version across mobile refrigeration and commercial A/C channels, making the exact 12V A2 identity useful for multi-market distributors. For this line, the commercial goal is a stable item identity for wholesale sales quote, refrigerated-commercial fleet maintenance and dealer 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 | Refrigerated trucks requiring higher-capacity TM21 R404a service |
| Voltage | 12V |
| 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 |
Compared with TM16, the TM21 family supports a larger displacement class; the commercial-vehicle buyer must still identify voltage, two-groove clutch and mount. Check the clutch from a straight front identity 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 12V, A2, 145 mm, ear-mount tm21 family; confirm bracket span and o-ring head connection; confirm orientation from the original unit on one sales quote line so belt path, connector position or hose layout cannot be hidden by a familiar casting.
Opened pages show this defined version across mobile refrigeration and commercial A/C channels, making the exact 12V A2 identity useful for multi-market distributors. 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.
commercial-vehicle buyer codes, barcode labels and local-language carton descriptions can be added while the underlying TM21 12V A2 145 mm identity remains on the packing and picking records. This preserves the information needed for a correct repeat dealer order.
Several pages support 12V and 145 mm, while one adjacent 24V page and different refrigerants show why model-family matching is not enough. A reliable first-dealer 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 12V 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 complete unit identity as one complete assembly.
Check 12V, two grooves and 145 mm, then record the head orientation and ear spacing before the item joins TM21 dealer inventory. Keep the carton label, commercial-vehicle buyer 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 dealer inventory.
A practical receiving check verifies the complete assembly, 12V 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 dealer inventory accuracy, not refrigeration-system diagnosis at goods-in.
The line suits refrigeration wholesalers needing a higher-capacity 12V twin-belt compressor for repeat orders. Elecdura can support neutral packaging, OEM labels or qualified ODM presentation for repeat demand. Customer item codes may be used while the exact compressor defined version 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 12V, 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-rear-port layout photographs with the dealer enquiry. 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 dealer inventory.
Send quantity, destination, target delivery window, packaging request and commercial-vehicle buyer item code together with the original reference and clear unit views. For 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 complete unit-specific sales quote without turning the page into an installation manual.
Yes. Keep every compressor line separate by model, 12V rating, A2, 145 mm description, refrigerant and image. Mixed cartons should preserve distinct labels so dealer dealer warehouse staff can receive and replenish the correct defined version 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-commercial fleet and private-label enquiries. The normal commercial reference is 50–100 pcs MOQ, a 7–15 day indicative lead time after dealer order confirmation and an 18-month warranty under agreed sales terms. Final terms depend on quantity, destination, packaging and the confirmed physical defined version.
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 12V TM21 A2, 145 mm R404a complete compressor and return a wholesale sales quote for distributor, importer, commercial fleet or private-label demand. Physical conflicts will be clarified before an dealer order advances, protecting dealer inventory accuracy and repeat-dealer order consistency.
