TM21 / TM-21 24V B2 150 mm configuration
24V refrigerated vehicles using a two-groove TM21 compressor and R404a
Transport refrigeration equipment requiring a 24V TM21 assembly with a B2 150 mm clutch
| Quantity: | |
|---|---|
The B2 version of the TM21 combines a 24V clutch and two-groove 150 mm drive for R404a transport refrigeration service. Elecdura positions this dual-belt compressor as an aftermarket replacement for professional regional wholesalers, distributors and importers. The exact two-groove specification and real dual-belt compressor image stay together from first enquiry through repeat purchase.
Exact public support for 24V 150 mm 2G helps buyers describe the unit, while the directory supplies the refrigerant and offer boundary. For this line, the commercial goal is a stable item identity for wholesale regional quotation, refrigerated-delivery fleet maintenance and regional inventory. The page keeps the decision points visible without reading like a service manual or promising fitment from a family name alone.
| Primary configuration | TM21 24V B2 150 mm |
| Compressor model | TM21 |
| Application family | 24V refrigerated vehicles using a two-groove TM21 compressor and R404a |
| Voltage | 24V |
| Pulley | B2, 150 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 |
Although B1 and B2 share 24V, 150 mm and the TM21 body family, the second belt groove makes them separate purchase and regional hub lines. Check the clutch from a straight front receiving image 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, B2, 150 mm, ear-mount tm21 family; confirm bracket span and o-ring head connection; confirm orientation from the original unit on one regional quotation line so belt path, connector position or hose layout cannot be hidden by a familiar casting.
Exact public support for 24V 150 mm 2G helps buyers describe the unit, while the directory supplies the refrigerant and offer boundary. 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.
regional wholesaler codes, barcode labels and local-language carton descriptions can be added while the underlying TM21 24V B2 150 mm identity remains on the packing and picking records. This preserves the information needed for a correct repeat wholesale order.
Adjacent references in the opened set use one groove or 145 mm, so a family-level cross reference cannot approve interchange. A reliable first-wholesale 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 a B2 150 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 dual-belt compressor identity as one complete assembly.
Count two grooves before measuring 150 mm, verify 24V and keep a clear head view with the B2 receiving record. Keep the carton label, regional wholesaler 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 regional inventory.
A practical receiving check verifies the complete assembly, 24V clutch, B2, 150 mm drive, ear-mount tm21 family; confirm bracket span and protected o-ring head connection; confirm orientation from the original unit. The purpose is regional inventory accuracy, not refrigeration-system diagnosis at goods-in.
This unit supports refrigerated fleets using dual-belt 24V drives and distributors offering B1 and B2 side by side. Elecdura can support neutral packaging, OEM labels or qualified ODM presentation for repeat demand. Customer item codes may be used while the exact compressor two-groove specification 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 B2, 150 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 layout photographs with the wholesale 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 regional inventory.
Send quantity, destination, target delivery window, packaging request and regional wholesaler item code together with the original reference and clear unit views. For 24V refrigerated vehicles using a two-groove TM21 compressor and R404a, add the refrigeration-unit make, vehicle or trailer model and equipment serial information when available. That context supports a dual-belt compressor-specific regional quotation without turning the page into an installation manual.
Yes. Keep every compressor line separate by model, 24V rating, B2, 150 mm description, refrigerant and image. Mixed cartons should preserve distinct labels so regional hub staff can receive and replenish the correct two-groove specification 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-delivery fleet and private-label enquiries. The normal commercial reference is 50–100 pcs MOQ, a 7–15 day indicative lead time after wholesale order confirmation and an 18-month warranty under agreed sales terms. Final terms depend on quantity, destination, packaging and the confirmed physical two-groove specification.
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 B2, 150 mm R404a complete compressor and return a wholesale regional quotation for distributor, importer, delivery fleet or private-label demand. Physical conflicts will be clarified before an wholesale order advances, protecting regional inventory accuracy and repeat-wholesale order consistency.
