Ai -30°C 30L Recirculating Chiller with 20L/Min Centrifugal Pump
Ai C30 series recirculating chillers are true thermostatic-control laboratory chillers. These closed-loop laboratory chillers are ideal for cooling rotary evaporators, analytical instrumentation, laser etching systems, ICP equipment, vacuum systems, plasma etching systems, and jacketed reactors. They can also be used as a replacement for tap-water cooling in laboratory applications.
Ai C30 compressor-based recirculating chillers offer strong performance, high reliability, quiet operation, and ease of use. A powerful force/suction pump provides constant flow rates, while the microprocessor PID controller delivers precise temperature control, including cooling below ambient temperature.
Important: -30°C / -22°F ultimate temperatures are tested under empty-load conditions, with no rotary evaporators or jacketed reactors attached.
