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.
Ex Protection Electric Motors | ATEX & Hazardous Areas
Thorne & Derrick work with global manufacturers of high voltage Ex motors and generators to supply ultra-reliable purge and pressurisation systems for installation in potentially explosive atmospheres – these Ex p protected systems protect thousands of motors worldwide with ambient temperatures as low as -60°C.
Ex Protection Electrical Panels | ATEX & Hazardous Areas
Thorne & Derrick can arrange the design and manufacture of MiniPurge units, custom enclosures and accessories specifically for electrical panels and control panel builders. Additionally, we can certify completed hazardous area systems using a variety of explosion protection concepts including Ex p, Ex e, Ex t.
