IKA Circulating Cooler, RC 2 GREEN basic, 0025004186

RC 2 GREEN basic
: A powerful, compact and energy-efficient recirculating chiller for cooling applications down to -30 °C. The natural refrigerant-powered compressor, which is demand-controlled and speed-regulated, achieves a cooling capacity of 800 W whilst consuming minimal energy.

The speed-controlled PEEK pump allows for indirect, infinitely variable adjustment of maximum pressure and flow rate. The integrated filling funnel and drain valve ensure safe and clean handling of the thermofluid. The easily accessible woven stainless steel mesh air filter guarantees consistent performance when cleaned regularly. Up to 2.5 l of thermofluid is available from the high-quality insulated 4 l bath reservoir for the external cooling circuit without the need for refilling.
