Sustainability

Lower environmental impact throughout the entire lifecycle without compromising performance. Thanks to their low weight, ease of installation, and reduced maintenance requirements, composite materials deliver a lower carbon footprint across the full product lifecycle. They also contribute to improved insulation and overall building efficiency.

The casing, which contains a high proportion of recycled material (interior up to 80%), further reduces the overall carbon footprint. A Life Cycle Assessment (LCA) is available on request.

In construction, composites offer a more sustainable alternative to traditional materials such as aluminium and steel, which are associated with higher carbon emissions due to energy-intensive production. Liberty is the one and only composite air handling unit in the world with a Eurovent Certificate.

Low weight

The composite design significantly reduces unit weight compared to traditional steel constructions, making LIBERTY up to 40% lighter than other solutions.

This lowers structural loads and simplifies installation, making it particularly well suited for older buildings with limited load-bearing capacity.

The reduced weight also minimizes transport, lifting and crane requirements. In addition, the flexible design supports a variety of layouts to accommodate architectural and space constraints, including side-by-side configurations that help keep overall construction height to a minimum.

First class casing performance

Designed to meet the highest requirements
Meets U1 (T1), TB1, D1, L1, F9 according to EN 1886.

LIBERTY units represent top-tier performance in thermal insulation, thermal bridging, casing strength, leakage and filtration.

Eurovent recommends these top classifications for applications where energy efficiency and hygiene are critical – such as healthcare, cleanrooms and high-performance buildings.

Full Eurovent certification ensures that declared values are independently tested and verified – not just calculated or assumed.

High classification levels make it easier to specify quality and ensure the unit performs as intended over time.

Corrosion Resistance

Designed for the harshest environments where conventional materials fail, LIBERTY provides corrosion resistance that exceeds C5 classifications.

LIBERTY is ideally suited for swimming pools, coastal installations, laboratories, wastewater treatment facilities and demanding industrial applications.

The metal-free design eliminates the risk of corrosion, while composite inner surfaces withstand cleaning agents and harsh chemicals. These durable materials ensure that the casing of LIBERTY maintains its structural integrity, air tightness and thermal performance year after year.

APPLICATIONS
