30HXC (286-1302kW) - Constructive Engineers Ltd

The 30HXC units are water-cooled chillers, designed from the ground up to meet the needs of today and tomorrow:

Non-ozone depleting HFC-134a refrigerant
Screw compressors
Fits through a standard door with no disassembly required- – mechanically cleanable evaporators and condensers

All units are equipped with Pro-Dialog Plus control to optimise the efficiency of the refrigerant circuit.

Seventeen sizes with nominal cooling capacities from 287 to 1302 kW.
PRO-DIALOG Plus control to optimise the efficiency of the refrigerant circuit.
Ozone-friendly HFC-134a refrigerant, proven, non-toxic, non-flammable.
Equipped with screw compressors for extremely quiet operation and low vibration levels.
Control is fully automatic and includes auto diagnostics.
Two independent refrigerant circuits.
Multiple compressor concept.
Series star/delta starter, limiting the start-up current on (30HXC 080-190).
Easy installation – compact design, fits through a standard door opening. Supplied as a complete package for easy installation. No extra controls, timers, starters or other items to install.
Single power point (30HXC 080 to 190), and one power point per circuit (30HXC 200 to 375).
