VHT vent heads

for safety and environmental protection

Simple, effective vent heads
for increased safety and environmental protection
Spirax Sarco VHT vent heads are suitable for vertical open-ended steam vent pipes. The vent head is designed to safely discharge
dry steam to atmosphere at low velocity, protecting personnel from injury, buildings from damage and minimising the nuisance of
water spray on the surroundings.

How the VHT vent head works
Steam flow entering the vent head is directed over an internal disc and
forced into a toroidal vortex, causing entrained water droplets to be flung
outwards and 'wetting out' onto the internal surface of the vent head.
As these droplets coalesce they are driven towards the internal drain by
the ‘downward’ rotation of the toroidal vortex.
