  • Recovered refrigerant into certified cylinder for storage on site.
  • Weighed and confirmed the charge.
  • Removed and replaced pressure relief valves.
  • Removed and replaced flow sensor.
  • Pressure tested with OFN (oxygen free nitrogen) to locate any leaks.
  • Discovered leak on the bottom of the condenser coil, brazed and re pressure tested.
  • Once proved released OFN (oxygen free nitrogen) to atmosphere and evacuated system to a minimum of 2 Torr.
  • Re-charged with recovered refrigerant and trim charged with virgin refrigerant.

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.

These units 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.
