Description
The compact HRC 2 GREEN basic cooling and heating circulation thermostat covers a wide working range from -30 °C to 100 °C and features a powerful, continuously variable pressure and suction pump. Its demand-driven, speed-controlled compressor lowers both noise and operating costs, while the natural refrigerant R290 delivers high energy efficiency and meets current environmental requirements.
High-quality insulation on the 4-liter bath enables particularly fast heating and reduces heat input at low temperatures, with up to 2.5 liters of thermal fluid available for the external circuit without refilling. An integrated funnel and drain valve ensure safe, clean handling, and an easy-open front flap gives convenient access to the stainless steel mesh air filter. A front drain valve lets a hose be connected to empty the bath without direct contact with the fluid.
Key features:
- Wide -30 °C to 100 °C working temperature range
