EHC Exhaust Heads

The EHC Series Exhaust Heads made from Ductile Iron, are used to separate entrained water and particles from steam prior to being discharged directly to the atmosphere. Typically used to eliminate water damage to rooftops and other equipment.

Description

EHC Exhaust Heads use the cyclonic effect. That’s where the velocity of the steam is used to generate centrifugal motion. That whirls the steam and throws the entrained water to the wall of the unit. There it is released to a drain below. Correct sizing of exhaust heads for steam service is important in order to assure the highest possible desiccation of the steam.

EHC Exhaust Heads shall be a cyclone design for vertical venting to atmosphere. Unit shall have a vortex containment plate feature to prevent re-entrainment of liquid. Exhaust Head to be constructed in ductile iron, carbon steel or stainless steel and available in FNPT and flanged connections.
