Function
Deaerators-dirt separators are used to continuously eliminate the
air and dirt contained in the hydraulic circuits of heating and
cooling systems. They are capable of automatically removing all
the air present in the system down to micro-bubble level. At the
same time they separate dirt and impurities contained in the water
within the circuit and collect them in the lower part of the valve
body, from which they may be expelled.
Versions fitted with a magnet are designed for the separation of
ferrous impurities.
The circulation of fully deaerated water enables the equipment to
operate under optimum conditions, free from any noise, corrosion,
localised overheating or mechanical damage.
Threaded, flanged and weld-end deaerators-dirt separators are
supplied complete with hot pre-formed shell insulation to ensure
perfect heat insulation when used in both hot and chilled water
systems.
