What Expo Technologies does
Expo Technologies is a UK-headquartered designer and manufacturer of purge and pressurization (Ex p) systems that protect electrical equipment — including large electric motors, generators, enclosures, analysers, and instrumentation — in hazardous areas where flammable gases, vapours, or dusts are present. Founded in 1950 (originally as Telektron) and headquartered in Sunbury-on-Thames with manufacturing centers in the UK, USA, and China, the company has installed more than 7,500 motor purge systems and protected more than 17,000 electrical enclosures and systems worldwide. Its core product portfolio spans motor purge and pressurization systems (D818/D758/D808 with low- and high-temperature variants from -60°C to +60°C), enclosure purge systems (MiniPurge Type X/Z/Y, SmartPurge II, SmartPurge Z), PressurEx pre-certified enclosures, and packaged solutions such as Ex Print hazardous area label printers, RP-Max room pressurization, and nitrogen buffer systems for API 618 reciprocating compressors. Differentiated technology includes the proprietary CLAPS (Closed Loop Automatic Pressurization System) and the all-in-one SmartPurge Z architecture.
The company sells engineered-to-order hardware via a global authorized channel partner network supplemented by direct enterprise sales and OEM integration relationships, with no public list pricing. Revenue is generated through hardware sales plus engineering, consultancy, certification, training, and lifecycle management services for the installed base. Customers are concentrated in upstream oil and gas, chemical and petrochemical processing, power generation, automation and control, OEM systems, and emerging hydrogen economy applications; named end-users and OEM partners include BP, Petrobras, Chevron, Siemens, ABB, Honeywell, Rockwell Automation, TMEIC, Yokogawa, Thermo Fisher, Servomex, Mettler Toledo, Hubbell, and Hyundai. Expo holds extensive international certifications (IECEx, ATEX, UL, cULus, FM, cFMus, UKCA, INMETRO, KOSHA, EAC, CCC, PESO, JPEx, NEPSI, ISO 9001, CE) and operates a wholly-owned subsidiary, Expo Process Analytics, focused on hazardous area process analytics equipment.
