IKA HRC 2 Green Control Heating & Cooling Bath, 20128747

The HRC 2 GREEN control cooling and heating circulation thermostat offers a wide operating range from -30°C to 100°C and features a powerful, continuously adjustable pressure and suction pump for precise temperature control. Its demand-driven, speed-regulated compressor reduces noise levels and operating costs, while the use of the natural refrigerant R290 ensures high energy efficiency and compliance with modern environmental standards. The well-insulated 4-liter bath enables rapid heating and minimizes 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 provide safe and clean handling of the thermofluid, while the front-access design allows easy cleaning of the stainless steel mesh air filter. A front drain valve with hose connection ensures safe emptying without direct contact with the fluid. The HRC 2 GREEN control is ideally suited as a peripheral unit for bioreactors, synthesis reactors, and other applications requiring efficient heat exchange and precise temperature control via an external temperature sensor. ‚Features: Speed-controlled refrigeration system unit with 620 W cooling capacity Natural refrigerant R290 Speed-controlled pump made of PEEK: (0.5 bar; 22 l/min) 1500 W heating capacity Digital level indicator Safety classification III (FL) according to DIN 12876 Adjustable safety circuit With the wireless controller (WiCo), the HRC 2 GREEN control can be operated safely and conveniently from anywhere. Process sequences can be simplified and automated thanks to 10 freely programmable temperature ramps, each with 10 steps.
