Ai SST -20°C to 99°C 7L Compact Recirculating Chiller 220V

Ai C20 series recirculating chillers are the true thermostatic control laboratory chiller, this closed laboratory chiller is 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 C20 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 2nd generation controller gives you the ideal solution when you need precise temperature control or cooling below ambient temperature.IMPORTANT! -20°C ULTIMATE TEMPERATURES ARE TESTED UNDER EMPTY LOAD CONDITION (NO ROTARY EVAPORATORS OR JACKETED REACTORS ATTACHED).C20 recirculating chiller features ETL tested to UL and CSA standards All stainless steel finish Powerful 2,000 watts heater Adjustable pumping speed up to 20 liters per minute 2nd generation 7" TFT touch screen controller No dry ice or liquid nitrogen needed ANSI standard all stainless steel reservoir All steel construction for durability Eco-friendly R404A refrigerant Small footprint saves valuable lab space Cost saving as the water consumption is completely eliminated Connection tubing included Recommended for 2L rotary evaporators and 2L-10L distillation systems Attention! Do NOT use Ai Chill-50 heat transfer fluid with this unit.
