TM21 / TM-21 24V PV8 137 mm configuration
24V refrigerated vehicles using a higher-capacity eight-rib TM21 compressor and R404a
Transport refrigeration equipment requiring a 24V TM21 assembly with a PV8 137 mm clutch
| Quantity: | |
|---|---|
The 24V PV8 TM21 is a complete R404a transport refrigeration compressor with a 137 mm eight-rib clutch for commercial-vehicle duty. Elecdura positions this aftermarket compressor as an aftermarket replacement for professional truck-parts purchasers, distributors and importers. The exact replacement specification and real aftermarket compressor image stay together from first enquiry through repeat purchase.
Exact 24V PV8 supplier pages demonstrate active international demand, but they also show the head and diameter variations that purchasing teams must control. For this line, the commercial goal is a stable item identity for wholesale RFQ response, refrigerated-truck fleet maintenance and replenishment replenishment stock. The page keeps the decision points visible without reading like a service manual or promising fitment from a family name alone.

It shares the front-drive format of the 12V PV8 unit, so the 24V electrical identity must be checked before a truck-parts purchaser approves any substitution. Check the clutch from a straight front comparison 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, PV8, 137 mm, ear-mount tm21 family; confirm bracket span and o-ring head connection; confirm orientation from the original unit on one RFQ response line so belt path, connector position or hose layout cannot be hidden by a familiar casting.
Exact 24V PV8 supplier pages demonstrate active international demand, but they also show the head and diameter variations that purchasing teams must control. 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.
truck-parts purchaser codes, barcode labels and local-language carton descriptions can be added while the underlying TM21 24V PV8 137 mm identity remains on the packing and picking records. This preserves the information needed for a correct repeat purchase line.
Public pages range from 137 to 141 mm and include different head orientations; none is allowed to override the directory-defined aftermarket compressor. A reliable first-purchase line 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 PV8 137 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 aftermarket compressor identity as one complete assembly.
Verify 24V first, then count eight ribs, measure 137 mm and capture a rear-pad connection image for the item file. Keep the carton label, truck-parts purchaser 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 replenishment replenishment stock.
A practical receiving check verifies the complete assembly, 24V clutch, PV8, 137 mm drive, ear-mount tm21 family; confirm bracket span and protected o-ring head connection; confirm orientation from the original unit. The purpose is replenishment stock accuracy, not refrigeration-system diagnosis at goods-in.
The unit is suitable for wholesalers supplying 24V refrigerated fleets and private-label programs with exact variant control. Elecdura can support neutral packaging, OEM labels or qualified ODM presentation for repeat demand. Customer item codes may be used while the exact compressor replacement 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 PV8, 137 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-pad connection photographs with the purchase 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 replenishment replenishment stock.
Send quantity, destination, target delivery window, packaging request and truck-parts purchaser item code together with the original reference and clear unit views. For 24V refrigerated vehicles using a higher-capacity eight-rib TM21 compressor and R404a, add the refrigeration-unit make, vehicle or trailer model and equipment serial information when available. That context supports a aftermarket compressor-specific RFQ response without turning the page into an installation manual.
Yes. Keep every compressor line separate by model, 24V rating, PV8, 137 mm description, refrigerant and image. Mixed cartons should preserve distinct labels so stocking location staff can receive and replenish the correct replacement 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-truck fleet and private-label enquiries. The normal commercial reference is 50–100 pcs MOQ, a 7–15 day indicative lead time after purchase line confirmation and an 18-month warranty under agreed sales terms. Final terms depend on quantity, destination, packaging and the confirmed physical replacement 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 PV8, 137 mm R404a complete compressor and return a wholesale RFQ response for distributor, importer, truck fleet or private-label demand. Physical conflicts will be clarified before an purchase line advances, protecting replenishment stock accuracy and repeat-purchase line consistency.
