Take advantage of an existing in-house water system for heat removal. Thermo Scientific™ System Water-to-Water Heat Exchangers use less energy and cost less to operate than traditional compressor-based chillers. They provide a clean, stable, controlled, closed-loop water cooling system that rejects the process heat into an existing in-house facility water supply. This eliminates the problems associated with the direct use of in-house water such as insufficient or fluctuating flow, changing pressure, poor water quality and temperature instability.

  • Cooling capacities up to 100kW
  • Simple, reliable design for years of worry-free operation
  • Compact footprint optimizes valuable floor space
  • Heat load sensing valve conserves facility water usage
  • Panel-mounted gauges monitor recirculating temperatures and fluid pressure (SYS-I and SYS-II)
  • Flow control valve allows precise setting of recirculating rate (SYS-III and SYS-IV)
  • High-temperature and low-liquid-level safety feature with status relay povide protection to temperature-sensitive applications

Recommended for:

  • Laboratory
  • Laser
  • Industrial
  • Semiconductor
  • Medical


Cooling capacity is based on a 10°C temperature differential between the cooling water supply and the cooling fluid flowing from the System to the instrument being cooled.
