Liberty Composite Air Handling Units
We are a Dutch manufacturer of composite air handling units. Since our start in 1983, we have supplied a wide range of fans. After the successful introduction of composite roof fans, we started developing and producing the Liberty product line: our unique series of fully composite air handling units. The Liberty air handling units are successfully used in our Dutch home market and abroad in both new construction and renovation projects. In addition to the chemical and food industry, we are also strongly represented in non-residential construction, swimming pools and healthcare and educational institutions.
Our company pays a lot of attention to quality and innovation. We hold relevant certifications for this purpose, including ISO 9001 and Eurovent. With the use of our own assembly and production lines, custom-built is possible. By continuously developing products, investing in employee expertise and considering customer feedback, we are able to supply the market with energy-saving solutions that are designed and built to last.
Since 2023, we have become a subsidiary of the HC Groep, market leader in the field of indoor climate technology in the Netherlands.
Why composite?
It is our vision that circularity starts with extending the lifespan of our air handling units. After all, this provides a longer service life (under similar conditions) which is always better than replacement by new products.
Liberty air handling units are made of composite. This results in air handling units that are cold bridge-free, strong and lightweight. They are designed to last extremely long, even in the most corrosive environment: CX extreme. Most metals will rust immediately upon exposure to the environment. This is a natural process that can be prevented by unnatural coating or environmentally harmful galvanising or coating. Composite is completely corrosion resistant and therefore does not require any surface treatment. Choosing composite minimizes our carbon footprint by at least 54%, compared to metal.
Our composite air handling units are unique because of their construction method which results in very low weight, corrosion proof and hygienic air handling units that meet the highest possible EN1886 standards.

Liberty Composite AHUs have an extremely low carbon footprint.
The Liberty Composite Air Handling Units with an air amount of 1000 – 80.000 m3/h can be applied in various buildings and industries:
Swimming Pools
The composite ‘Liberty’ Air Handling Unit is the superb solution to withstand exposure to chlorine compounds and excessive moisture in the extracted air from swimming pools.
Food industry
The corrosion free casing construction with specifically selected high quality internal components provide a sustainable solution for nearly any industrial ventilation system. Particularly where a high hygienic (VDI 6022) is required, the Liberty air handling units with a complete smooth inner surface are an outstanding solution.
Health care
The corrosion free and hygienic design of the ‘Liberty’ air handling unit are the perfect match for the great variety of health care ventilation applications like operation rooms, laboratories and recreation areas.
Chemical industry
Aggressive vapours have no influence on the casing, fan and other components of our composite air handling units. All fasteners are made of stainless steel AISI 304/316. The standard casing construction is classified C5 according to ISO 12944-2.
