Our ventilation units: AHU custom-made

Fresh air tailored to your needs 
WEGER specialises in ventilation and air conditioning technology (air handling units and plant engineering) for all industries and is therefore active both regionally and internationally. From planning and production to delivery and assembly, we offer sophisticated all-round solutions from a single source.
The original product and basis of the ventilation and air conditioning units designed by WEGER is the DIWER series of units and its further developments DIWER TE and DIWER EVO. Its modular frame construction allows for easy structural extensions and flexible connection to the pipeline network.
In addition to the respective device, we offer various additional modules, also in integrated form. This will complete your system or provide you with a plug and play solution. 
We offer weatherproof, hygiene-oriented or, for use in potentially explosive environments, ATEX-compliant versions.
The housings of our DIWER, DIWER EVO and DIWER TE device series impress with high-quality, tested materials, durability and careful workmanship and user-friendly handling. The device series differ in their thermal insulation and thermal bridge factor.
The cross-section and material selection of a ventilation device depend on the needs of the customer, the structural conditions and possibilities. Our individually adapted, freely configurable, double-walled air handling units with modular design can be adapted to customer requirements with millimetre precision in horizontal and vertical versions. They can be adapted for the respective purpose. Materials and components can be freely selected.

The selection and use of our built-in components are subject to the highest standards of quality, energy efficiency and environmental compatibility.
The development and design of our air conditioning units, including their materials and components, reflect the current state of the art and are subject to a continuous improvement process. 
Of course, all national and international standards and guidelines are respected and their compliance is documented with certificates.

Frame construction with a rivet-free clamping rail system

An essential component of our ventilation units is an intelligent frame system. This allows for countless structural variations and stands out for its uncompromising material and workmanship quality.

Thermal panel

Our double-walled thermal panels are elegantly designed and smooth, with no screw connections. The panels inserted into the frame construction are enclosed in a continuous, endlessly foamed, spray-applied, pressure-resistant, and permanently elastic PUR seal.

Base frame

Various reasons may require an additional base frame under the HVAC unit, such as ensuring the unit’s stability or accessibility in snowy conditions.

Sight glass

WEGER never stops evolving, and this is demonstrated by one of our latest innovations.

Hygiene

The vertical unit Vi-Pure II from WEGER addresses the problem of poor air quality and impresses with its well-known flexibility in design.

Weather resistance

Due to architectural considerations, technical building equipment is often external to the structure. HVAC units are frequently installed on rooftops.
