Ai -30°C 40L Recirculating Chiller with 30L/Min Centrifugal Pump

Regular price $12,990.00



Ai C30-40 series recirculating chillers are the true thermostatic control laboratory chiller, these closed laboratory chillers are ideal for applications such as cooling rotary evaporators, analytical instrumentation, laser etching, ICP, vacuum systems, plasma etching and jacketed reactors. This system can also be used as a replacement to tap water cooling in laboratory applications.

Ai C30-40 are compressor-based recirculating chillers that offer outstanding performance and high reliability as well as quiet operation and ease-of-use. Powerful force/suction pump provides constant flow rates, while microprocessor PID controller gives you the ideal solution when you need precise temperature control or cooling below ambient temperature.


C30-40 circulating chiller features

  • ETL tested to UL and CSA standards
  • No dry ice or liquid nitrogen needed
  • Advanced PID digital temp controller
