This Sanden 507-type heavy-duty refrigeration compressor is configured with a 12V electromagnetic clutch, a A1 single-groove belt pulley, and a pulley diameter that must be confirmed from the original unit. It is an aftermarket replacement option for selected R404A transport refrigeration and mobile cooling systems.
It is supplied for professional repair channels, compressor distributors, importers and fleet-maintenance purchasing programs. A correct selection requires comparison of the original label, clutch voltage, belt drive, pulley measurement, mounting ears and port layout.
This version gives buyers a defined Sanden 507-family configuration rather than a generic compressor-body match. Its 12V clutch, A1 belt drive and not stated in the source template should be checked as one set against the removed unit.
Sanden 507 family identification must be confirmed separately from similar compressor families, even where external layouts appear similar. The product should not be chosen from a photograph alone because similar housings can be supplied with different clutch coils, pulley profiles and pulley offsets.
Elecdura can review original label images, pulley measurements and photographs of the mounting and ports before a wholesale quotation is prepared.
Matching principle: model family, voltage, belt drive and pulley diameter must all agree before mounting and port details are reviewed.

The stated 12V rating applies to the electromagnetic clutch coil. A 12V clutch must be used with the matching 12V electrical control circuit.
A visually similar 24V clutch compressor is not an electrical substitute. Incorrect voltage can cause non-engagement, unreliable operation or coil damage.
This product uses a A1 single-groove belt pulley. The A1 arrangement uses one belt groove. It must be compared with the original single-groove belt path and pulley alignment; it is not a direct substitute for a two-groove or multi-rib configuration.
Compare the original belt type with the pulley face and confirm that the belt runs in the same plane as the installation bracket.
The source template does not state a pulley diameter for this configuration; measure the original pulley and send the measurement for confirmation before ordering. Include pulley offset and belt alignment in the inspection, not diameter alone.
A matching pulley profile with a different diameter can change belt speed and positioning. The original assembly remains the selection reference.
Compatibility cannot be confirmed by the Sanden 507 family name alone. Review the complete electrical, belt-drive and physical configuration before ordering.
Confirm that the original compressor is a Sanden 507-family unit, not a TM16 or another look-alike family.
Verify the original electromagnetic clutch is rated 12V.
Confirm the A1 pulley profile and 1-groove arrangement.
Measure the pulley outer diameter and submit the reading for matching confirmation.
Check pulley offset, belt alignment and bracket clearance.
Compare mounting ears, bolt positions and overall mounting geometry.
Compare suction and discharge port positions, head shape and port orientation.
Confirm the original system refrigerant, lubricant specification and oil quantity requirements.
Recommended matching information: send the original compressor label plus front, rear, side and pulley-view photographs before a bulk order.
When a label is damaged or incomplete, photographs with a visible pulley measurement and mounting details provide useful comparison evidence. Final fitment remains subject to the complete compressor and refrigeration-unit configuration.
This Sanden 507-type 12V compressor is intended for selected belt-driven mobile refrigeration systems requiring the A1 drive; confirm pulley diameter against the original unit.

These are application categories, not guaranteed vehicle or unit fitment. The original label, voltage, drive, mounting and port arrangement must be verified before installation.
For mixed-configuration orders, separating models by clutch voltage and pulley drive prevents avoidable receiving errors. Order details can be reviewed against the agreed product specification before shipment.

MOQ, samples, packaging options and lead time are confirmed against the final model list, quantity and supply conditions.
No. The clutch coil voltage must match the system electrical circuit. A voltage mismatch can prevent correct clutch operation and may damage electrical components.
Do not assume interchangeability. This compressor requires a A1 1-groove drive; belt profile, groove count, pulley offset and alignment must match the removed unit.
Measure across the outer edges of the original pulley at its widest point and send the reading for confirmation because a diameter is not stated in the source template. A photograph showing the measuring tool is useful for a matching review.
No. Refrigerant reference is only one selection point. Compressor family, clutch voltage, belt drive, pulley size, mounting, ports and lubricant requirements must also be compatible.
Please provide the original label, front and rear photographs, a pulley photo with voltage and diameter details, mounting and port images, quantity and destination country.
