Enviro-Line purging units is an enclosure pressurization system for non hazardous areas that operates on a supply of compressed instrument air or inert gas. It regulates and monitors the pressure within the sealed enclosure at a constant pressure in order to prevent the accumulation of damaging and caustic gases and dusts.

The elimination of these gases and dusts extends the life of expensive electrical equipment and instrumentation placed within the Enviro-Line purging unit.

Due to higher pressures inside the electrical enclosure, corrosive environments remain outside. The system maintains a constant 0.5" water pressure inside the enclosure for protection against gas and/or dust.
