Enviro-Line Pressurization Systems

Enviro line

Enviro-Line Purge Units are an enclosure pressurization system for use in non-hazardous areas and the principle of operation is based on the supply of compressed instrument air or inert gas. They are responsible for regulating and monitoring the pressure inside the sealed casing to prevent the accumulation of caustic and harmful gases and dust. Enviro-Line purge units are casing pressurization systems for non-hazardous areas and whose operating principle is based on in the supply of compressed instrument air or inert gas. They are responsible for regulating and monitoring the pressure inside the sealed casing with a constant pressure value to prevent the accumulation of caustic and harmful gases and dust.

Removing these dusts and gases extends the life of expensive electrical equipment and instruments that are installed in the Enviro-Line purging unit.

The higher pressures inside the electrical enclosure insulate from corrosive environments that remain on the outside. The system maintains a constant 0.5" water pressure inside the casing to protect from the effects of gas or dust.
