Smoke and Heat Extraction Systems (RWA) and Air Conditioning Systems

All our products are developed and manufactured to the newest Standards as per EN 150 9001.

The RWA equipment (light domes, louvre extractors, single and double flap ventilators) are tested to meet the requirements of EN 12102-2

The high quality of these systems allows them to be used for daily ventilation. Our products meet the new energy saving regulations (ENEV) and achieve lower U- values. Our comprehensive programme enables us to offer you a wide range of standard products as well as  tailor-made solutions to comply with your project concept.


What makes our products special:

  • High energy efficiency.
  • High degree of operating efficiency for standard air conditioning (units open to 90°)
  • Rain proof air conditioning through side flaps construction is possible.
  • Very effective noise reduction values
  • Construction with optimal U- values is possible
  • High ratings for static loading by wind and snow due to stable construction.
  • Heat insulated and thermal separation configuration is available (Environmentally Friendly).
  • Selectable daylight use with Polycarbonate or Glass and/or with the addition of aluminium panel.
  • Manufactured with low and maintenance free high quality recyclable material.
  • Constructed with aluminium for low unit weight.
  • Available in a variety of sizes customized to meet the customers requirements – sizes up to 2500mm X 3500mm can be accommodated.
  • Available for pneumatic or electrical operation.
  • Low installation and low purchase costs together with efficient RWA Flow Volume (higher Cv – Values).
  • We will assist you with engineering co-operation, in meeting regulation requirements and costing as per EN Standards.
  • We recommend a combination our products for example – roof flashing and personnel fall safety equipment.
