TM21 / TM-21 24V B1 150 mm configuration
24V refrigerated vehicles using a single-groove TM21 compressor and R404a
Transport refrigeration equipment requiring a 24V TM21 assembly with a B1 150 mm clutch
| Quantity: | |
|---|---|
This TM21 complete compressor uses a 24V coil and single-groove 150 mm clutch for R404a refrigerated-vehicle applications. Elecdura positions this refrigeration compressor as an aftermarket replacement for professional cold-chain operators, distributors and importers. The exact single-groove specification and real refrigeration compressor image stay together from first enquiry through repeat purchase.
A 24V 150 mm one-groove TM21 is a specialized stocking line for refrigeration distributors rather than a generic TM21 replacement. For this line, the commercial goal is a stable item identity for wholesale cold-chain operation quotation, refrigerated-cold-chain operation maintenance and service service stock. 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 B1 150 mm |
| Compressor model | TM21 |
| Application family | 24V refrigerated vehicles using a single-groove TM21 compressor and R404a |
| Voltage | 24V |
| Pulley | B1, 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 |
The B1 single-groove drive is the decisive difference from the otherwise similar B2 150 mm version and must be visible on the RFQ. Check the clutch from a straight front goods-in 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, B1, 150 mm, ear-mount tm21 family; confirm bracket span and o-ring head connection; confirm orientation from the original unit on one cold-chain operation quotation line so belt path, connector position or hose layout cannot be hidden by a familiar casting.
A 24V 150 mm one-groove TM21 is a specialized stocking line for refrigeration distributors rather than a generic TM21 replacement. 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.
cold-chain operator codes, barcode labels and local-language carton descriptions can be added while the underlying TM21 24V B1 150 mm identity remains on the packing and picking records. This preserves the information needed for a correct repeat replenishment order.
The exact Ecoclim page supports 24V 150 mm 1G, while adjacent TM21 pages use two grooves, 145 mm or other refrigerants. A reliable first-replenishment 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 B1 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 refrigeration compressor identity as one complete assembly.
Count exactly one groove, confirm 150 mm and 24V, then verify the head and mount before this unit is labeled B1. Keep the carton label, cold-chain operator 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 service stock.
A practical receiving check verifies the complete assembly, 24V clutch, B1, 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 service stock accuracy, not refrigeration-system diagnosis at goods-in.
This single-groove specification is intended for buyers who maintain single-belt refrigeration equipment and need exact carton separation. Elecdura can support neutral packaging, OEM labels or qualified ODM presentation for repeat demand. Customer item codes may be used while the exact compressor single-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 B1, 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-refrigerant connection photographs with the replenishment 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 service service stock.
Send quantity, destination, target delivery window, packaging request and cold-chain operator item code together with the original reference and clear unit views. For 24V refrigerated vehicles using a single-groove TM21 compressor and R404a, add the refrigeration-unit make, vehicle or trailer model and equipment serial information when available. That context supports a refrigeration compressor-specific cold-chain operation quotation without turning the page into an installation manual.
Yes. Keep every compressor line separate by model, 24V rating, B1, 150 mm description, refrigerant and image. Mixed cartons should preserve distinct labels so cold-store depot staff can receive and replenish the correct single-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-cold-chain operation and private-label enquiries. The normal commercial reference is 50–100 pcs MOQ, a 7–15 day indicative lead time after replenishment order confirmation and an 18-month warranty under agreed sales terms. Final terms depend on quantity, destination, packaging and the confirmed physical single-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 B1, 150 mm R404a complete compressor and return a wholesale cold-chain operation quotation for distributor, importer, cold-chain operation or private-label demand. Physical conflicts will be clarified before an replenishment order advances, protecting service stock accuracy and repeat-replenishment order consistency.
