Pioneers in natural and energy-efficient cooling, heating and refrigeration.
Since its founding in 2004, Enex is a technology leader in the commercial and industrial refrigeration sectors, specializing in the design and production of high-efficiency refrigeration systems using natural refrigerant CO₂. Enex pioneered CO₂ refrigeration technology worldwide, revolutionizing the refrigeration sector and establishing itself as a leader in technological excellence.
More than 1,000 Enex transcritical CO₂ industrial and commercial refrigeration and air-conditioning systems operate across Europe in all climate conditions. Enex also pioneered the application of CO₂ refrigerant for HVAC chillers and heat pumps, which are the most energy efficient solutions for sanitary hot water.
Enex offers a wide range of solutions covering commercial refrigeration, brine and water-cooled chillers, heat pumps for sanitary hot water, industrial refrigeration and refrigeration systems for freezing tunnels.
Enex continues to grow according to its founding core values: determination, innovation, sustainability, quality and customer care.
Our global reach is backed by solid numbers.
World pioneers of CO2 cooling, heating and refrigeration since 2004.
CO₂ is the only natural refrigerant that is non-toxic and non-flammable. CO₂ refrigerant is available all over the world in unlimited amounts, and with a GWP of 1 it will never be subjected to F-Gas regulations.
The innovators at Enex studied and improved CO₂ cycles from the beginning, implementing revolutionary solutions such as overfed evaporators, expansion energy recovery to pre-compress vapour, and an economiser system to improve efficiency at high ambient temperatures.
In addition, Enex developed many solutions to recover heat and use it for heating in systems where CO₂ refrigerant is used for cooling. These technologies, which work with both direct circulation of CO₂ refrigerant and with water as an intermediate fluid, were developed and perfected over the course of a four-year project. The result is high energy savings, and in countries where Enex operates, such as Switzerland, this type of solution is increasingly common.
Our customers trust our products to help make them successful, every day.
We are driven by strong values to create a better and more sustainable world.
One mission: to protect the planet by developing high efficiency, natural refrigerant technologies that reduce global warming while providing superior results for our customers.
We are committed to achieving carbon neutrality in all of our facilities.
