Heating and cooling technology GENERAL CATALOGUE EDITION 18 Cooling/Refrigerators and Freezers ex protected 1 Spark-free laboratory refrigerators The BGR 120 laboratory guidelines state that interiors of refrigerators in which AQUALYTIC dangerous, explosive atmospheres can develop, must be spark-free. Such explosive atmospheres can be created by stored flammable liquids, for example. The laboratory refrigerators by Aqualytic® meet these requirements. The interiors are free from sparking sources and are therefore explosion-proof. With glass shelves. Variable temperature control from +2°C to +10°C. Temperature is continuously controlled by thermostat. Capacity External Internal Weight Power Temp. PK Cat.
