COMPANY

About

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.

TECHNOLOGIES

Our leading natural refrigerant, energy efficiency and energy transition technologies transform the HVACR industry.

Enex is committed to developing and improving innovative and efficient low global warming technologies in HVAC, commercial and industrial refrigeration systems that reduce energy consumption and environmental impact.

CO₂

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.

The first element to consider to reduce environmental footprint is energy consumption. A well-designed cooling, heating and refrigeration unit consumes less energy and reduces impact on costly electricity production infrastructure. Enex has introduced and uses innovative solutions like ejectors for evaporator overfeeding and for expansion energy recovery, parallel compression, low Delta T in evaporators thanks to overfeeding, and complete heat recovery in combined heating and cooling systems, among others, to increase efficiency.
The transition away from hydrocarbons such as gas, oil and coal towards renewable energy sources such as photovoltaic, wind and hydroelectric requires a change to the way heat and cold are produced. The Enex product range includes units with zero environmental impact that are engineered for a carbon-neutral future. Enex Technologies’ innovative solutions are designed for energy transition, reducing total cost of ownership while increasing our customers’ peace of mind.
