WHAT IS the DC-3 system?

This is a revolutionary system which will redefine our industry with a plug and play system for walk in/reach in cool rooms.

The birth of DC-3 began with Actrol drawing on the expertise of four world renowned organisations, Siam Compressor Industries, Carel, Tecumseh, and Cabero to work together to produce what we now know as the DC-3 smart refrigeration system.

Siam Compressor Industries supply the brushless DC scroll compressor, Carel provide the electronic controls, Tecumseh manufacture the condensing unit, and Cabero supply the uniquely specified evaporator fitted with EVD ice.

The system will be packaged in two cartons like a split system air conditioner with the condensing unit and controller in one carton and the evaporator in another.

Condensing unit display shows real time system information, so you know exactly what is happening as it’s happening.

End user

Quieter system with low noise outside thanks to the modulating fans and compressor.


Smart Refrigeration Technology ensures higher heat exchange efficiency, adequate oil return, and safety controls to ensure the compressor operates within its design envelope.

End user

Flexible capacity range means you have room to move with your cool room layout in future.


Easy maintenance with vital signs shown in plain English on condensing unit display.

End user

Safety mode ensures continuous cooling if communication between components is lost.

The control system is integrated into all three components of the system enabling real time adjustments to maximise the coefficient of performance (COP). Suction and condensing pressures float to minimise energy input while providing very stable room temperature control.

DC-3’s stable room temperatures will extend the shelf life of many products. Compressor cycling is almost eliminated and defrosts minimised. Customers can also rely on a long system life with features such as a speed boost function which temporarily increases the compressor speed to assist oil return, EEV controlled oil return and liquid injection and an evaporator washing cycle that flushes oil from the evaporator to maximise heat transfer. The system will be packaged in two cartons like a split system air conditioner with the condensing unit and controller in one carton and the evaporator in another.
