Gas-emitting hot and cold water-based processes are ventilated to protect operators and plant and equipment using a variety of collection devices ranging from hoods to lip plenums.

The gases, odours and surrounding air having been drawn out by a fan must be cleansed to render their impact on the environment to standards set by regulatory authorities.

e-RPM designs and delivers fume arrestors and scrubbers which neutralise and remove the gases from the ventilated air.

e-RPM gas cleaning technologies cover a wide range of methods including:

• Aerodynamic blade droplet arrestors
• Packed tower absorption units
• Venturi scrubbers
• Peat based bio filters

Fabrications are made in plastics and stainless steel to give corrosion free service. The energy lost from a building where air is exhausted may be transferred from the exhausted gas to the replacement air using recovery heat exchangers reducing facility heating costs.
