Thorne & Derrick, The Explosive Atmosphere Experts, are specialists in the design and supply of products including enclosures with hazardous area protection by purge and pressurisation (Ex p) – we work with end users, integrators and OEMs across a wide range of industries, including oil and gas, chemical and petrochemical, pharmaceutical and biotechnology and power generation.
The Principle of a Pressurized Apparatus
The entry of a surrounding atmosphere into the enclosure of the electrical apparatus is prevented by maintaining a protective gas, inside the enclosure, at a higher pressure than the surrounding atmosphere. The overpressure is maintained either with or without a continuous flow of the protective gas.
