3 Technical description
3.1 General description
BL 150...500-2 are high performance independent domestic hot water
tanks.
DHW calorifiers BL 150...500-2 can be connected to central heating
boilers used for heating domestic hot water.
Main parts:
4 The tanks are made of high quality steel lined with food quality
standard enamel vitrified at 850°C, which protects the tank from
corrosion.
4 The heat exchanger welded into the tank is made of smooth
tubing, the external surface of which, which is in contact with
domestic water, is enamelled.
4 The appliance is insulated with polyurethane foam, which helps to
reduce heat losses to the minimum.
4 The tanks are protected against corrosion by one or more
magnesium anodes.
