History
MVM EGI, Less Water, More Power

Since 1948, MVM EGI has been at the forefront of energy innovation. Our journey began when our founders, dr. Heller László and dr. Forgó László, developed a game-changing solution to reduce water use in energy production: the Heller System® (an indirect dry cooling system). This pioneering spirit still drives us today as we deliver advanced, sustainable cooling solutions for a changing world.


With over seven decades of expertise, we are more than just a cooling technology provider – we are a trusted partner in energy efficiency and environmental stewardship. We specialize in engineering, designing, and manufacturing cutting-edge air-cooled and wet cooling systems, including indirect dry cooling (IDCS), air-cooled condensers (ACC), wet (evaporative) cooling, and combined wet-dry (hybrid) cooling solutions. Our solutions serve a wide range of applications, from fossil fuel power stations and industrial processes to nuclear power plants, including large-scale plants and SMRs, as well as critical emergency cooling systems. Beside these our portfolio includes patented CircumixTM ash handling technology for coalfired plants.

From our roots in Hungary, MVM EGI has grown into a global leader in cooling technologies and energy efficiency, bringing forward-thinking solutions to power plants and industries worldwide. Backed by the strength of the MVM Group, Central Europe's 6th-largest energy conglo-merate, we continue to set new standards in cooling technology – building on tradition to power the future.


History:

  • 1948 - establishment of the Energy Management Institute (EGI) for post-war reconstruction of energy infrastructure.
  • 1954 - two Professors of the Budapest University of Technology (Dr. László Heller and Dr. László Forgó) developed the Heller System® dry cooling system for power plants, the great advantage of which is that it does not consume water at all compared to previous water-intensive solutions.
  • 1989 - the development of an ash management solution for coal-fired power plants began. The patented solution called Circumix® enables the environmentally friendly disposal of the resulting ash.
  • 1990s - EGI became a leading energy designer, manufacturer and contractor in the Hungarian energy market, with serious export markets (1,300 employees).
  • 1992 - during the privatization, the German GEA group acquired EGI and integrated it into its power plant business.
  • 2003 - GEA EGI established a subsidiary in Beijing and a heat exchanger factory in Wuquing (80 km from Beijing). (Both companies are 100% owned by the Hungarian company) ENEXIO Cooling Syst. Trad. (Beijing) Co. Ltd & ENEXIO Cooling Systems (China) Co. Ltd.
  • 2014 - GEA sold the Heat Exchanger business to a German financial investor, to Triton Partners, which continued to operate under the new name ENEXIO (www.enexio.com), with which EGI also operated in the future as ENEXIO Hungary Zrt.
  • 2016 - ENEXIO Hungary closed and liquidated its heat exchanger plant in Jászberény, Hungary and installed the entire production in China.
  • 2019 - Triton started the sale of the ENEXIO Dry Cooling business, including the ENEXIO Hungary Zrt. in it.
  • 2020 - ENEXIO Hungary Zrt. and its two Chinese subsidiaries are acquired by MVM Group www.mvm.hu.
  • 2021 - ENEXIO Hungary becomes MVM EGI.
