Ciat Chiller Features

The AQUACIAT Chillers have been adapted for heating and air conditioning applications in the fields of Offices, Healthcare, Industry, Administration, and Commercial  buildings.

Some Ciat Chillers are designed for outdoor installation and do not require protection from adverse weather conditions.

To operate in COOLING or HEATING mode, these units use outside air as the only external source, this permits the evacuation of heat in summer or the supply of thermal energy for heating in winter.
