operation, the heat exchangers can be
connected for greater efficiency and an
increase in total system efficiency. The
two-layer enamelling, protected by two
magnesium protective anodes, is durable
and highly resistant. Cleaning flange,
connections for circulation and
immersion heater, thermometer and sensor
connection as standard. The high-quality
hard foam insulation ensures minimal
