TM21 / TM-21 12V PV8 137 mm configuration
Refrigerated vehicles using a higher-capacity eight-rib TM21 compressor and R404a
Transport refrigeration equipment requiring a 12V TM21 assembly with a PV8 137 mm clutch
| Quantity: | |
|---|---|
This 12V TM21 uses a 137 mm eight-rib clutch to serve higher-capacity refrigerated-vehicle systems operating with R404a. Elecdura positions this defined compressor as an aftermarket replacement for professional program managers, distributors and importers. The exact source-defined build and real defined compressor image stay together from first enquiry through repeat purchase.
A transport refrigeration program manager may encounter TM21, QUE21XD or supplier-specific numbering; the defined compressor page keeps those searches tied to one hardware definition. For this line, the commercial goal is a stable item identity for wholesale program quote, refrigerated-fleet program maintenance and program 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 12V PV8 137 mm |
| Compressor model | TM21 |
| Application family | Refrigerated vehicles using a higher-capacity eight-rib TM21 compressor and R404a |
| Voltage | 12V |
| Pulley | PV8, 137 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 PV8 drive is the main physical separator from two-groove TM21 program inventory, while the 12V coil keeps it distinct from the adjacent 24V PV8 version. Check the clutch from a straight front source view 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, PV8, 137 mm, ear-mount tm21 family; confirm bracket span and o-ring head connection; confirm orientation from the original unit on one program quote line so belt path, connector position or hose layout cannot be hidden by a familiar casting.
A transport refrigeration program manager may encounter TM21, QUE21XD or supplier-specific numbering; the defined compressor page keeps those searches tied to one hardware definition. 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.
program manager codes, barcode labels and local-language carton descriptions can be added while the underlying TM21 12V PV8 137 mm identity remains on the packing and picking records. This preserves the information needed for a correct repeat program release.
Opened pages include 137 and 141 mm PV8 measurements plus a mislabeled page title, so the directory value controls the customer specification. A reliable first-program release 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 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 defined compressor identity as one complete assembly.
Count eight ribs, measure 137 mm, verify 12V and inspect the rear connection before accepting the unit into the refrigeration range. Keep the carton label, program manager 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 program inventory.
A practical receiving check verifies the complete assembly, 12V 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 program inventory accuracy, not refrigeration-system diagnosis at goods-in.
This source-defined build supports refrigerated-fleet program accounts that need an eight-rib 12V TM21 option in mixed wholesale shipments. Elecdura can support neutral packaging, OEM labels or qualified ODM presentation for repeat demand. Customer item codes may be used while the exact compressor source-defined 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 12V, 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-manifold connection photographs with the program 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 program inventory.
Send quantity, destination, target delivery window, packaging request and program manager item code together with the original reference and clear unit views. For 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 defined compressor-specific program quote without turning the page into an installation manual.
Yes. Keep every compressor line separate by model, 12V rating, PV8, 137 mm description, refrigerant and image. Mixed cartons should preserve distinct labels so program program warehouse staff can receive and replenish the correct source-defined 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-fleet program and private-label enquiries. The normal commercial reference is 50–100 pcs MOQ, a 7–15 day indicative lead time after program release confirmation and an 18-month warranty under agreed sales terms. Final terms depend on quantity, destination, packaging and the confirmed physical source-defined 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 12V TM21 PV8, 137 mm R404a complete compressor and return a wholesale program quote for distributor, importer, fleet program or private-label demand. Physical conflicts will be clarified before an program release advances, protecting program inventory accuracy and repeat-program release consistency.
