IKA Works Rc2 Green Control, Recirculating Chiller, Control

Powerful, compact and energy-efficient recirculating chiller for cooling applications up to -30 °C. The on-demand and speed-controlled compressor, operated with natural refrigerant, achieves a cooling capacity of 800 W at minimum energy consumption.

The speed-controlled PEEK pump allows an indirect continuous adjustment of maximum pressure and flow rate. The device provides an external temperature control interface. A PT 100.30 temperature sensor is included in the scope of delivery. The wireless controller (WiCo) shows all relevant process parameters at a glance and enables comfortable and safe operation of the device.

The integrated filling funner and drain valve enable safe and clean handling of the thermofluid. With regular cleaning, the easily accessible stainless steel woven mesh air filter guarantees consistent performance. The high-quality insulated 4 l bath reservoir allows the use of up to 2.5 l of thermofluid in the external cooling circle without refilling.
