Adiabatic cooling
Sustainable cooling for a greener future
Cooling with water
Menerga's adiabatic cooling is an advanced technology harnessing natural evaporation to achieve efficient and eco-friendly cooling. Water is evaporated into the ambient air, resulting in its cooling. This chilled air is then directed into indoor spaces, leading to a pleasant temperature reduction. Adiabatic cooling enables significant energy savings by eliminating conventional refrigerants and optimizing the use of ambient air. It offers a sustainable solution for maintaining cool indoor environments, particularly in hot climates.

Save energy and operating costs
Embrace sustainability
From an economic standpoint as well, adiabatic systems pay off for the system owner. Low power consumption reduces operating costs. Furthermore, the elimination of the compression refrigeration system, means a reduction in maintenance and regular leakage tests (as required under F-Gas regulations).

Experience the future of air treatment with Menerga's adiabatic cooling technology
Efficient and sustainable
At Menerga we use the principle of adiabatic evaporative cooling in our ventilation systems. Depending on the specific requirements, we offer different types of evaporative cooling techniques:
Adiabatic recooling
Adiabatic recooling is often used in conjunction with heat removal or heat recovery. It utilises the evaporation effect to remove heat from a medium. Evaporation removes heat and cools the medium. This is particularly efficient when cooling water is required for processes or equipment.
Direct adiabatic evaporative cooling
With this technology, the evaporative cooling effect comes into direct contact with the air. Water is sprayed into the air, causing evaporation and cooling the air. This cooled air is then channelled into the room. Direct adiabatic evaporative cooling is well suited for applications where an increase in room humidity is acceptable.
Indirect adiabatic evaporative cooling
This technology uses the evaporation effect to cool the air, but without direct contact between the air and the cooling medium. In an indirect adiabatic evaporative cooling system, the warm air is channelled through a heat exchanger that is in contact with a moist medium. The medium cools the air without moisture entering the air flow at the same time. The cooled air is then channelled into the room. This enables efficient cooling without increasing the humidity in the room.
Combinations of evaporative cooling methods
In addition, we can also explore combinations of these evaporative cooling methods. Working closely with you, your architects and engineers, we specialise in identifying the most suitable adiabatic cooling approach and the perfect Menerga adiabatic system for your individual application.
