Recirculating Chillers RC 2 Control
Recirculating Chillers RC 2 Control
Product Code : 4173000
Product Description

High efficient and temperature-stable circulating chiller with unique wireless controller. Designed for cooling applications up to -20 °C with powerful 400 W cooling capacity.
The speed-controlled PEEK pump allows an indirect continuous adjustment of the maximum pressure and flow rate. Due to its outstanding temperature stability of about ± 0.05 K (@ -10 °C), the RC can handle even the most demanding applications.
Via the connection socket for an external Pt100 temperature sensor, it is possible to measure and control temperature directly in the working medium.
With the wireless controller (WiCo), it is possible to operate the RC2 safely and comfortably independent of the device position.
By using the 10 freely programmable temperature ramps with 10 steps each, it is possible to simplify and automate process sequences.
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 l bath reservoir allows the use of up to 2.5 liters of thermofluid in the external cooling circle without refilling.
