Description
The HRC 2 GREEN basic cooling and heating circulation thermostat offers a wide working temperature range from -30°C to 100°C and is equipped with a powerful, continuously adjustable pressure and suction pump.
Its demand-driven, speed-controlled compressor minimizes noise levels and operating costs, while the use of the natural refrigerant R290 ensures high energy efficiency and compliance with current environmental standards. The well-insulated 4-liter bath enables rapid heating and reduces unwanted heat input at low temperatures.
Up to 2.5 liters of thermofluid are available for external temperature control circuits without refilling. An integrated filling hopper and drain valve ensure safe and clean handling of the thermofluid, while the front-access panel allows easy cleaning of the stainless steel mesh air filter. A front drain valve with hose connection enables safe emptying without direct contact with the fluid.
The HRC 2 GREEN basic is ideally suited as a peripheral unit for bioreactors, synthesis reactors, and other applications requiring efficient heat transfer to or from external systems.
