Circulator baths

The compact refrigerated and heated circulators are renowned for their high energy efficiency and on-demand and speed-controlled compressor, which reduces noise and operating costs. The high-quality isolation of the 4 l bath allows fast heating and reduces heat input when cooling. Using the external temperature control circuit, it is possible to have up to 2.5 l thermofluid without a refill. The integrated hopper and drain valve ensure safe and clean handling of the thermofluid. The HRC 2 control in combination with an external temperature sensor is perfectly suitable to precisely temper external closed or open applications.

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. Due to the excellent temperature stability they can handle even sophisticated applications. The isolated, high-quality bath has an integrated hopper and drain valve, ensuring safe and clean handling of the thermofluid.
