cold room ventilation Poland

...GCR swirl diffuser is equipped with fixed blades bent at a constant angle. It is made of galvanized steel sheet, powder coated in RAL9010. Swirl diffusers ensure mixing of the fresh air stream with the room air, which is recommended for supplying cold air. They provide a stable flow of the stream and are intended for rooms up to 4m high, for example in public facilities such as hotels, restaurants, office buildings. The perforated plate leads to rapid air flow velocity decrease at low noise levels.

...Air curtains separate heating zones with different temperatures. The SV family of industrial curtains consists of several models with air performance ranging from 6,000 to 23,000 m³/h. The air curtain limits heat exchange between thermal zones, the room, and the external environment. The device is designed to provide forced air flow in a horizontal or vertical direction (depending on the installation). The modular construction allows for any stream dimension ranging from 1.3 to 6 m.
