What ELMESS Thermal System Technology does
ELMESS Thermal System Technology is a German manufacturer of custom-engineered electrical industrial heating systems specializing in explosion-proof (ATEX/IECEx-certified) equipment for hazardous-area operations in zones 1, 2, 21, and 22. Founded in 1945 in Berlin by Herbert Schweda and relocated to Uelzen in 1966, the company has built an 80-year track record of pioneering explosion-protected electric heaters, including the first Ex-proof electric heater with integrated temperature monitoring developed in 1956 in cooperation with the PTB. Today it operates as a wholly-owned subsidiary of Sweden's NIBE Group, following a 2022 acquisition, and manufactures its entire product range at a single integrated ~3,000 sqm facility in Uelzen, Germany, employing approximately 88 staff.
The product portfolio spans immersion heaters, explosion-proof high-performance cartridge heaters, flow heaters (0.5 kW to 4 MW), gas preheaters (up to 500 bar / 400°C / 650°C), air heaters (1.0 kW–2 MW), power-to-heat systems, fan heaters, finned tube and space heaters, plus a complementary control ecosystem of temperature controllers, level monitors, control cabinets with thyristor controllers, and electronic thermal cut-out devices. Block-type heaters using a tube coil cast in an aluminium block are a proprietary differentiator. Applications span process industry, oil & gas, industrial gases, hydrogen technology, pharmaceutical, packaging/food, machinery and plant construction, and energy/environmental technology. The company has delivered 4,200+ devices to 578 customers across 43 countries, with named enterprise logos including Air Liquide, BASF, Bayer, Dow, Linde, Messer, Siemens, MAN, Solar Turbines, Atlas Copco, Burckhardt Compression, BHEL, Johnson Controls, and GEA.
Revenue is generated primarily through project-based hardware sales of custom-engineered capital equipment, priced per quotation against specifications, power rating, certifications required, and quantity, alongside recurring after-sales service, commissioning, spare parts, and repairs. The go-to-market combines direct technical sales engineers at Uelzen headquarters with a multi-tier channel-partner distribution network across Europe, Africa, Asia, the Middle East, Oceania, and South America, supplemented by active participation in international trade shows (Expoquimia, Gastech, Hydrogen Technology Expo, Adipec). Strategic expansion priorities include the emerging hydrogen economy, industrial process heat decarbonization via electrification, and a 100% ecological Thermobattery in development with NBank and EFRE support.
