Elecdura supplies aftermarket heavy-duty refrigeration compressors for refrigerated trucks, refrigerated vans and mobile transport cooling systems. This category focuses on belt-driven compressor configurations used by professional refrigeration repair businesses, parts distributors, importers and wholesale buyers.
Selecting a transport refrigeration compressor requires more than comparing its external appearance. The compressor family, clutch voltage, pulley profile, number of grooves, pulley diameter, mounting arrangement, port position, refrigerant and lubricant requirements must all be checked before ordering.
Our current heavy-duty refrigeration compressor range includes TM16-type, TM21-type, 507-type and 7H15-type configurations. Available specifications include 12V and 24V clutch options together with A2, PV8, B1 and B2 pulley arrangements for different belt-drive systems.
Compatibility notice: Model names and application descriptions are provided as product-selection references. Final compatibility should be confirmed using the original compressor label, clutch voltage, pulley measurements, mounting details and suction and discharge port arrangement.
Our TM16-type product range includes 12V and 24V clutch configurations with A2 and PV8 pulley options. Buyers can select between different pulley diameters according to the belt-drive layout of the original transport refrigeration system.
TM16-type compressors are commonly sourced by refrigerated-vehicle repair businesses and aftermarket distributors that require multiple voltage and pulley configurations within the same compressor family.
The TM21-type range provides a wider selection of belt-drive arrangements, including A2, PV8, B1 and B2 pulley configurations. Both 12V and 24V options are available for selected specifications.
Because TM21-type compressors may use different pulley profiles and diameters, buyers should confirm the complete clutch and pulley specification rather than ordering according to the TM21 family name alone.
Additional 507-type and 7H15-type belt-driven compressors are available for selected refrigerated-vehicle and mobile cooling applications. These products should be matched by clutch voltage, pulley arrangement, mounting pattern, port configuration and system refrigerant requirements.
Where the original compressor model is unclear, buyers can send the compressor label and detailed product photographs to Elecdura for review before quotation.

The specifications above provide a category-level reference. Please review the individual product page or contact Elecdura before placing a wholesale order.
Begin with the model shown on the original compressor label. Confirm whether the existing unit belongs to the TM16, TM21, 507, 7H15 or another compressor family. A similar housing shape does not necessarily indicate interchangeability.
Check whether the original system uses a 12V or 24V electromagnetic clutch. The compressor body may look similar across different voltage versions, but the clutch coil must match the vehicle electrical system.
Confirm whether the compressor uses an A-profile, B-profile or multi-rib pulley. A2, PV8, B1 and B2 configurations represent different belt arrangements and should not be treated as interchangeable.
Two compressors from the same family may use different pulley diameters. Measure the outer pulley diameter and compare it with the product specification to support correct belt alignment and installation.
This category includes selected compressors configured for transport refrigeration applications, including selected R404a system requirements. Refrigerant and compressor oil compatibility must be verified for every product and should not be assumed from the compressor appearance alone.
Check the mounting ears, bolt locations, cylinder-head arrangement and suction and discharge port direction. These physical details are especially important when replacing a compressor used in a customized transport refrigeration unit.
Many compressor listings rely mainly on a product photograph and a general model name. Elecdura uses a specification-based review process to help professional buyers reduce uncertainty before purchasing.
For a more accurate match, buyers can provide:
A clear photograph of the original compressor label
Front, rear and side photographs of the compressor
Clutch voltage
Pulley profile and number of grooves
Pulley outer diameter
Mounting dimensions and bolt positions
Suction and discharge port orientation
Refrigerant and oil information
Vehicle or refrigeration-unit model
Required quantity and destination country
This information allows the Elecdura team to compare the original unit with available heavy-duty refrigeration compressor configurations before preparing a quotation.
For wholesale orders, consistency between the approved sample and the production batch is as important as the appearance of a single compressor. Our order-review process focuses on the specifications that directly affect product identification and installation.
Verification may include:
Compressor family and label information review
12V or 24V clutch confirmation
Pulley profile and groove-count inspection
Pulley diameter measurement
Mounting and port-layout comparison
Clutch and rotational-condition checking
Port protection before packing
Packaging and product-label confirmation
Batch consistency review for bulk orders
Inspection requirements can be discussed according to the product model, order quantity and target market.

MOQ, sample availability, packaging options and production lead time are confirmed according to the selected compressor model and order quantity.
A heavy-duty refrigeration compressor circulates refrigerant within a mobile cooling system used to control cargo temperature. Unlike a standard passenger-compartment A/C compressor selection, transport refrigeration applications may require different refrigerant, lubricant, voltage, pulley and operating configurations.
Use the original compressor label and complete physical specification as the main reference. Confirm the compressor family, clutch voltage, pulley profile, groove count, pulley diameter, mounting arrangement and port position. Do not select a replacement only because the two units have a similar appearance.
No. The electromagnetic clutch voltage must match the electrical system of the refrigerated vehicle or refrigeration unit. A 12V and a 24V compressor may share a similar housing but use different clutch coils.
They should not be assumed to be interchangeable. These pulley types use different belt profiles or numbers of grooves. Buyers should verify the original belt type, groove count, pulley diameter and belt-alignment position.
This category includes selected products intended for R404a transport refrigeration requirements, but refrigerant and lubricant compatibility must be confirmed for each individual model. Always compare the product specification with the original system information before installation.
Please provide the original compressor label, product photographs, voltage, pulley type, pulley diameter, mounting details, port direction, refrigerant, required quantity and destination country. More complete information supports faster and more accurate product review.
Private-label packaging, product labels and customized packing requirements can be reviewed according to the compressor model, order quantity and project requirements. Buyers should provide their branding and packaging specifications during the quotation stage.
Send Elecdura the original compressor model, label photograph and complete specification. Our team can review additional sourcing options even when the required model has not yet been published on the website.
