Why choose Cleanstream 550/H1500?

  • Patented Liquid-Liquid thermoelectric heat exchanger for precise control of corrosive chemicals or high purity fluids
  • HDPFA Teflon® wetted surfaces on process side for ultra-high purity or corrosive fluids
  • Eliminates possibility of metal contamination in baths
  • Combines the benefits of a Cleanstream 1100 and a Cleanstream H3000 – cooling on one side, heating on the other
  • Equivalent to 1,250 watt chiller or 1,500 watt heater
  • ±0.05°C control capability
  • Temperature control from 10°C to 90°C
  • Designed for easy integration inside most wet bench systems
  • 10x better response time than PFA Teflon compatible compressor-based chillers/heaters
  • All thermoelectric for high reliability – no compressor, no Freon
  • Simple design – no moving parts
  • Facility water (PCW) cold plate is sealed hard anodized for corrosion resistance
  • Powered using our highly reliable Switchback power supply (sold separately)
  • Perfect for HF baths, electroplating baths, corrosive chemical baths or high purity liquids
