HydroCIAT (420 to 1170 kW)

Product overview


HYDROCIAT complies with applicable standards for preserving the ozone layer (ODP – Ozone Depletion Potential) and limiting the greenhouse effect (GWP – Global Warming

Potential). All HYDROCIAT components are optimised to operate with R134a

refrigerant ensuring high performance coefficients, reduced energy consumption and extended service life. The refrigerant circuit has been studied in great detail. Each step has been checked to ensure that each unit is perfectly sealed. In addition, the use of a direct expansion evaporator enables refrigerant loads to be reduced to a minimum.


15 models (1800X to 4800X HPS)

Two acoustic versions available: Standard – Low Noise

Range of Use:

Heating capacity from 500 to 1400 kW

Cooling capacity: 370 to 1170 kW


The new generation of HYDROCIAT air-cooled water chillers provides an optimal solution to all cooling applications in offices, healthcare facilities, commercial premises, industrial facilities and apartment buildings.

These units are designed to be installed inside a plant room protected from freezing temperatures and bad weather conditions

This new range is optimised to run with the ozone-friendly HFC refrigerant R134A. They thereby meet the most demanding specifications in terms of environmental protection and high seasonal energy efficiency (ESEER) requirements.
