Supply and exhaust air systems

resource-saving solutions for safety and comfort

With energy- and resource-efficient supply and exhaust air systems for industrial and process ventilation, laboratory ventilation and air conditioning, and hospital ventilation and air conditioning, HLU supports you in your current challenges. In the comfort sector, our supply and exhaust air systems ensure comfort and wellbeing. You will receive a system that is precisely matched to the building and the way it is used.

Energy-efficient plastic central exhaust air units

HLU’s central air handling units have a proven record in the industrial sector for chemically contaminated industrial and process exhaust air. Thanks to innovative heat-recovery concepts, plastic central air handling units enable heat recovery of 68% in accordance with DIN EN 308. They meet the requirements of the Ecodesign Directive of 2018 and are TÜV tested in accordance with DIN EN 1886.

Supply and exhaust air systems

resource-efficient supply and exhaust air systems for your unique challenges

The requirements for occupational health and safety and environmental protection are constantly increasing and require measurably effective measures in buildings and industrial plants. HLU supports you in your challenges with energy- and resource-efficient supply and exhaust air systems. Our services range from planning supply and exhaust air systems, process development, and component project planning and production to installation and maintenance. We put a team with a high level of expertise and flexibility at your service, to ensure your installation is completed on time and within budget and to support you in achieving your goals.

Reach your goal on time and within budget with professional project management
Air-conditioning and ventilation systems are highly individual projects that we adapt to your needs. Our project team of commercial and design engineers is at your side throughout to successfully manage your construction project from planning to commissioning. The project management team is always available to answer your questions and requests during the project execution.

Customised construction for every purpose and requirement
Device types differ in terms of the materials used as well as the air treatment functions. Fresh air (outside air) is treated by using air filters, air heaters and/or air coolers as required together with economical heat recovery systems. Central air-conditioning systems for chemically contaminated exhaust air are manufactured from plastics and designed by our engineers and plastics specialists according to the customer’s specific requirements, based on the nature of the chemical contamination of the exhaust air.

The inner and outer surfaces of the fresh air and exhaust air units are defined according to the intended use. They may be steel with galvanised or PU coating, stainless steel or plastic – our material flexibility is to your advantage for a permanently functionally reliable system.
Thanks to the large number of design variants, our central air handling units can be individually adapted to your specific requirements. Designs can be realised for a multitude of possibilities, for instance: for inside/outside installation, with C&I technology or for hazardous areas – according to your specifications.

State-of-the-art technology from design to documentation
Your project is designed three-dimensionally with the latest CAD programs. We use RUKON and AutoCAD software. System pressure loss, noise level and flow behaviour in the system can be calculated and optimised. A clear overview and coordination with external trades are vital factors for successful implementation on site and for maintaining efficiency during installation and commissioning.
The 3D plans that are produced are an essential part of the documentation for the systems we design.

Assembly and commissioning of your optimally coordinated air conditioning and ventilation system
On-site supervision of the construction project by the project management team and our senior fitters ensures adherence to the specified construction schedule and expert execution of planning and construction. Direct contact with the on-site construction management and cordial working relationships with the other trades involved in the project help to bring the goal within reach.
After final commissioning and adjustment, we deliver an operationally safe, consumption-optimised air conditioning and ventilation system to you that perfectly meets your requirements.
