Areas of application
The expertise of Deweerdt & Masterveil Europe is not limited to the non-ferrous sector. From the world of foundries, our drive was increasingly noticed in other sectors. Subsequently, we transitioned to offering high-quality niche techniques for a wide range of companies.

- Logistics – Warehouses, distribution centers, and loading docks with high door cycles
- Industry – Production halls, workshops and cleanrooms
- Food – Production environments where hygiene and temperature control are crucial
- Refrigeration industry – Cold rooms, refrigerated storage and distribution
- Freezing sector – Deep-freezing environments down to -25°C and lower
- Mouthhouses – Storage of raw materials under stable climate conditions
- Tobacco and cigar storage – Protection of tobacco products against moisture and temperature fluctuations
Technologies: Invisible doors & Climate control
Airstop® & Powerstream®
Masterveil specializes in 'invisible doors'. Thanks to the exceptional performance of our patented technologies, we can reduce air exchange due to temperature differences and even block wind. The Airstop® high-pressure system blocks natural air exchange caused by temperature differences. The fan operates with EC technology and is controlled via the door control or the building management system.
Powerstream® is specially developed for large freezer cells in combination with conditioned anterooms. The function of temperature and moisture separation is here split into two separate air streams, resulting in extremely low energy consumption.
Freezing Solutions & Dehumidification
In freezer rooms, moisture is the biggest enemy. By combining air curtains with active dehumidification (desiccant wheel), we prevent ice formation, reduce the need for defrosting and increase safety. This leads to a fast payback time and a more stable business operation.
