Our scale ice makers NRE are equipped with a horizontal rotary evaporator and a fixed stainless steel water tank with a large distance to the evaporation cylinder and a large drain opening. This allows that the machine can be cleaned and disinfected very easily every day with high pressure and foam, as with food processing machines, without dismantling the stainless steel water tank. The NOCK scale ice makers operate with R449A refrigerant, offering low global warming potential and high energy efficiency. The scale ice has a thickness of approx. 2mm and a temperature of approx. minus 8°C.
