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

Ai -30°C 40L Recirculating Chiller are the true thermostatic control laboratory chiller.

Applications: 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 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.
