RC 2 basic

High-efficiency circulating chiller with powerful 400 W cooling capacity. Designed for cooling applications up to -20 °C.
The speed-controlled PEEK pump allows an indirect continuous adjustment of the maximum pressure and flow rate. Due to its excellent temperature stability of about ± 0.1 K (@ -10 °C), the RC 2 can handle even sophisticated applications.
The included feed hopper and bleed valve enable the safe and clean handling of the thermofluid. An easy to open front hood allows for convenient cleaning of the air filter.
The high quality insulated 4-liter bath reservoir allows the use of up to 2.5 liters of thermofluid in the external cooling circle without refilling.
