Description

Harsh conditions, such as corrosive, dirty or dusty environments, can shorten the life of electrical components and systems, even inside enclosures, leading to increased maintenance, premature failure and additional costs.

Enclosure pressurisation with clean dry air is an ideal protection method, as it prevents contaminants from entry.

Building on Expo’s proven pneumatic purging technology, the Mini Environmental Pressurisation System (MiniEPS), is a low cost, simple to install unit.
