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. Screwed version VHT2S show

The new VHT has been designed with an internal drain feature to recover valuable condensate that would have otherwise been discharged to an external drain, with the possibility of hot condensate exceeding temperature limits for ground drainage pipework. Installation For sizing and selection and range available see the Technical Information sheet for VHT vent heads. All products ordered will be supplied with a copy of our...
