Digital Scroll Compressor Copeland

In traditional air cooling systems the output capacity is monitored by  on / off compressor control. The accuracy of the control mode is not very good and the compressor starts and stops frequently, which is not too good for its useful life.

The Digital Scroll air-cooled system breaks the traditional design. It is designed with a parallel connection of a Digital Scroll compressor and one (or two) fixed Scroll compressors. The system can achieve a linear fit of its capacity, from 0.5 % to 100 %, this range is one of the larger from the sector. When the system is operating at partial load, it is possible to  adjust accurately the cooling or heating power.

Modular System

Modular design that allows up to 16 units can operate together, it can form an equipment of up to 1 024 kW.

Easy connection

Easy connection between the master and slave units. All units can be connected via a wired remote control (included with each unit) using a three pole shielded cable.

Safeguard function

If the unit gives an error code (E *)

– If it is in the master unit, all units stop (a slave unit can be configured as master unit to leave the system in service temporarily).

– If the error is in a slave unit, just that unit stops.

If the unit gives a protection code (P *), the unit stops but the rest keep ongoing, regardless of whether it is not the master unit (except PE and P9 codes).

New heat exchangers

More reliable system thanks to the new heat exchangers. 30 kW modules incorporate a heat exchanger of double pipe, while the 65 kW modules carry shell and tube heat exchanger.

Check function

From the display of the electronic board of the unit you can check various operating parameters in real time.

Built-in wired remote control

All series units incorporate a control that lets you adjust all operating parameters.

Quiet operation

Design optimized to minimize fan noise level.
