RDK7-24 groups the motor, compressor and controller in a stainless enclosure. It is the compressor-drive component for cabin cooling installations with separate condensers and evaporators, including projects integrating with an existing refrigeration circuit.
1.5 kW or 2 kW brushless motor options; these are motor ratings, not cooling output.
45, 92 or 120 cm³ compressor options.
Oil separation and single-LED diagnostics in the enclosed drive arrangement.
What you get
The quoted drive comprises the selected motor, compressor and controller assembly. Condenser, cabin evaporator and connecting refrigeration circuit are separate. Integration with an existing vehicle circuit requires compatible pressure controls, oil return and changeover control.

Fit & installation
Mechanical installation
Provide clean ambient air through both ends of the enclosure. Keep the drive away from exhaust heat and debris, and retain access to the refrigerant connections and controller.
Electrical installation
Size the supply cables, fuse and charging system for the selected drive and the other vehicle loads. The compressor drive, condenser fans and cabin blower all contribute to the power requirement.
Engine-off cooling
The condenser fans must operate during electric compressor operation. Include the cabin blower and condenser fans in the battery protection and shutdown arrangement.
Dual-compressor systems
A shared circuit requires the correct oil-separation, oil-return and changeover arrangement. Match the OEM compressor, heat exchangers, refrigerant connections and controls as a complete installation.
- Include charging capacity and engine-off operating time in the electrical brief.
- For an existing A/C circuit, provide the schematic and intended changeover operation.
