Function
Air separators are used to remove continuously the air contained
in the hydronic circuits of heating and cooling systems. The air
discharge capacity of these devices is very high. They are capable
of removing automatically all the air present in the system down to
micro-bubble level.
The circulation of fully de-aerated water enables the equipment to
operate under optimum conditions, free from any noise, corrosion,
localised overheating or mechanical damage.
Flanged versions of DISCAL air separators can be supplied
complete with pre-formed shell insulation to ensure perfect heat
insulation when used in both hot and cold water systems.
