Product Description

High quality at competitive prices. This ‘GuardPro’ Range comes in 3 types each with length options of 1.5m & 2m. The GuardPro ‘W’ is the hot water-fed (LPHW) range. The Guard Pro ‘E’ is the electric range and the GuardPro ‘C’ is the ambient air/fan only range for entrances where no additional comfort heat is required.

Suited to installation at entrances to large retail centres & shops, building reception halls, sports halls, loading/unloading  bays in supermarkets, hotels, factories & warehouses etc. with  lots traffic coming and going.

Modular design concept – two or more units can be used side by side to cover large entrances, in both vertical or horizontal orientation.

The Air curtains use a set of high-performance fans with a diameter of 450mm, which in combination with the appropriate and optimally selected shape of the air flow ducts has allowed a long range of air stream up to 7.5m. The universal design of the device allows the use of the same modules both vertically and horizontally.

The Sonninger GuardPro C ambient air model can also assist in the de-stratification of heat in large spaces by encouraging air movement around the building.
