Chillers Cooltech

Chiller unit – is a compact chilling machine for liquid cooling.

Chiller with Plate Heat Exchanger or shell-and-tube heat exchanger (PHE/ST) is a compact, all complete chiller solution, consisting of PHE/ST evaporator and condenser, screw compressor, oil and liquid separators, electric motor, microprocessor-based control and monitoring, starter panel, etc. All components are integrated on a compact base frame, and the package is supplied fully piped and wired with the following built-in advantages:

  • Operates with ozone-friendly refrigerant ammonia which protects your investment from future environmental restrictions;
  • High efficiency with small refrigerant volumes;
  • Highly efficient screw compressors;
  • Minimum temperature differences, pressure losses and high degree of oil separation with general operational efficiency;
  • Liquid separation system for efficient separation of even small liquid particles;
  • Specially developed oil return system which  separates the oil from the refrigerant and returns it automatically to the compressor;
  • Highly resistant PHE/ST material (AISI 316 or titanium) makes direct cooling possible;
  • No risk of bursting due to freezing.

All the chiller packages are supplied with COOLTECH microprocessor control and monitoring system, developed especially for COOLTECH compressors. It is equipped with a logic, easy-to-read display which informs you of all essential pressures and temperatures, motor current as well as low and high alarm limits. It features built-in capacity regulation of the compressors and by means of an interface it can be connected to a central computer or PC for remote operation. All operating conditions can be logged centrally and the same applies to quick changing of parametres..

Upon the request of the customer we can produce ammonia or Freon liquid cooling system with different types of heat-exchanger such as shell-and-tube exchanger and film evaporator. Condenser can be replaced with plate heat-exchanger on the same frame or with aerial evaporative condenser located on the roof:
  • capacity range up to 5000 kW for one unit;
  • brine temperature -35 °С up to +20 °С.
Production timedates from 12 weeks.
