Electrical panel solution for refrigeration compressor units with variable-speed drive (VSD)

Electrical panel solution for refrigeration compressor units with variable-speed drive (VSD)

Sabroe VSD (Variable-Speed Drive) panel solutions are the ideal way to integrate the unique Sabroe combination of refrigeration compressor unit know-how with electrical and controls experience and technologies. This paves the way to optimising the operation of refrigeration compressor units, and thus bring down here-and-now operating costs as well as longer-perspective life cycle costs for the owner.

Sabroe VSD panels are integrated electrical panel solutions with a built-in frequency inverter and additional control equipment that together make them very easy to integrate into your overall power supply and control system.

Adding an optional UniSAB systems controller makes the VSD panel a complete plug-and-play controls and motor drive solution, ready to ensure your compressor package delivers maximum cooling power with minimum life cycle costs.

Factory-mounted units provide the best value for money, because delivering complete pre-vetted units ensures troublefree operation and an electrical installation in full accordance with relevant standards and best practice. It also ensures endusers big savings on the man-hours required for configuring the overall equipment set-up.


  • SABROE VSD panels are competitively priced electrical panel solutions that contain a frequency inverter and everything needed for easy, compliant integration into the overall power supply and control system.
  • Integrating a SABROE VSD panel into any variable-speed compressor unit will shave off a major part of the man-hours normally allocated to electrical engineering, design, documentation, installation and commissioning of the compressor, chiller or heat pump unit.
  • Combining a SABROE VSD panel with a UniSAB systems controller brings down the life cycle cost of the compressor unit as a whole. Improved part-load characteristics (higher COP), achieved by a combination of the unique UniSAB yield control philosophy and the variable speed, along with the load-based service utility (service on demand) integrated in the UniSAB unit, provide the owner with an extremely flexible compressor package with the big additional benefits of low life cycle costs.
