Hydro Separator
series 548
CALEFFI
Function
This device consists of several different functional components,
each of which meets specific requirements, typical of the circuits
used in heating and air-conditioning systems.
· Hydronic separator
To keep connected hydronic circuits totally independent from
each other.
· Dirt remover
To permit the separation and collection of any impurities present
in the circuits. Provided with a valved connection with discharge
piping.
· Automatic air vent valve
For automatic venting of any air contained in the circuits.
Provided with a valved connection for maintenance purposes.
