Ministat 240 Refrigerated Heating Circulator

The Ministat 240 Refrigerated Heating Circulator is a versatile laboratory device designed for precise temperature control within a wide range of -45°C to 200°C. It features a 5.5-liter bath volume and is equipped with a "Pilot ONE" controller for accurate regulation. The circulator offers substantial cooling capacities at different temperature points, including 0.6 kW at 20°C, 0.55 kW at 0°C, and a minimal 0.05 kW at -40°C, alongside a heating capacity of 1.6 kW. It utilizes silicon oil as the heat transfer fluid, which is colorless and has a viscosity of 20 mm²/s at 25°C. The device includes pressure and suction pumps with maximum flow rates of 22 l/min and 16 l/min, respectively, and connects via M16x1 male fittings. Power is supplied at 208V, 2-phase, 60Hz, and it can operate with natural refrigerants or suitable domestic alternatives, supporting open or closed systems with temperature ranges from -20°C to 195°C, and up to 235°C in closed systems.
