IKA Circulating Cooler, RC 2 GREEN control, 0025006638

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

The speed-controlled PEEK pump allows for indirect, stepless adjustment of maximum pressure and flow rate. The recirculating chiller also features an interface for external temperature control. A PT 100.30 temperature sensor is included in the scope of delivery. The wireless controller (WiCo) displays all relevant process parameters at a glance and enables convenient and safe operation of the unit.
The thermofluid can be handled safely and cleanly using the integrated filling funnel and drain valve. 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.
