The condensing units are prefabricated, monoblock type, factory tested and easy to mount on the cold room's wall. Built in electronic control panel with microprocessor allows for manual setting of the desired temperature. It has the following features:
1) An on-off button for switching the unit on and off
2) An on-off light button
3) Three temperature setting buttons
4) A manual defrosting button
5) A digital display showing the current room temperature
All condensing units can be equipped with the different types of the refrigerant according to the client's requirements.
