RC 5 control

Powerful recirculating chiller, designed for external cooling applications up to -30°C.
The energy-efficient chiller is operated with an eco-friendly refrigerant and reaches a high power density. This results in a comparatively small working space in the lab. The speed-controlled PEEK pump allows an indirect, continuous adjustment of the maximum pressure and flow rate. Due to the PT100 temperature sensor, which is part of the delivery and its excellent temperature stability of about ± 0,1 K, the RC 5 can handle even sophisticated applications.
Laboratory staff operates the RC 5 control safely and conveniently from everywhere in the lab by using the Wireless Controller (WiCo). Processes can be automated and simplified through 10 freely programmable temperature ramps with 10 steps each.
Its isolated, high-quality 7l bath has an integrated hopper and drain valve, ensuring safe and clean handling of the thermofluid. A hose can be connected to empty the bath in order to avoid direct contact with the thermofluid.
The easy-to-open front flap allows an easy cleaning of the cooling unit’s air filter.
