Description
Compact-type condensate collector (vertical design)
with internal immersion tube and integrated bellowssealed
stop valves (V 20.8/K). Without immersion
tube as steam manifold V 20.8 with integrated
bellows-sealed stop valves. Lateral connections
in DN 15, 20 or 25 available. Collecting tube in
DN 40.

Function V 20.8/K
The condensate discharged by the steam trap flows
downwards between immersion tube and external
collecting tube, thereby creating a water pocket into
which the immersion tube enters. The space between
immersion tube and collecting tube above the water
pocket acts as a dampening cushion consisting of
flash steam and air bubbles. This steam cushion
effectively prevents water hammer like a dampening
pot.
The condensate flowing into the unit will be forced
into the higher condensate collecting line as a
function of its service pressure (differential pressure).
