FDK Compressor Units – Direct Drive Refrigeration Solutions
FDK Compressor Units provide a robust and practical solution for commercial and industrial refrigeration applications requiring a directly driven compressor configuration. The BOCK FDK range combines proven compressor technology with a shaft clutch and strong profile base frame to create a dependable, service-friendly compressor unit.
The compressor is mounted securely to the profile base frame, with power transmitted from the drive motor to the compressor through an elastic shaft clutch. IEC standard IMB3 motors can be used as the drive motor option, providing flexibility when specifying the unit for different refrigeration applications.
Robust Direct Drive Compressor Design
A key advantage of FDK Compressor Units is their robust yet maintenance-friendly construction. The profile base frame provides a stable foundation for the compressor and motor, while the elastic shaft clutch provides effective force transmission between the two components.
Special features include:
- Robust profile base frame construction
- Direct drive compressor arrangement
- Elastic shaft clutch for force transmission
- Compatibility with IEC standard IMB3 drive motors as an option
- Practical design for commercial and industrial refrigeration
- Multiple unit sizes for different application requirements
Designed for Easier Maintenance
Maintenance has also been carefully considered within the BOCK FDK design. The shaft clutch can be divided while the unit remains installed, allowing maintenance work to be carried out on either the compressor or motor without requiring them to be dismantled from the base frame.
This service-friendly design can help simplify maintenance procedures and minimise unnecessary disruption when working on refrigeration equipment.
