Heating circulators, HBC series
Supplier: IKA
The HBC circulating baths have a high-quality stainless steel bath, an extended temperature range for tempering fluids in open and covered water baths up to 200/250 °C. The LED/ graphic TFT Display illustrates all relevant process parameters. The large surface of the radiator allows for an optimum heat exchange and a smooth warming of the medium. Units feature push and turn buttons for intuitive menu navigation. All models conform to the highest safety classification III (FL) for use with flammable liquids according to DIN 12876. HBC immersion circulators ensure short heating up times and have a temperature stability of ±0,01 /0,02 K ( basic/control model). The units have an integrated cooling coil, adjustable safety circuit and a front drain valve for safe emptying. To drain the system, a separate valve helps to avoid direct contact with fluid.
