High Duty Models

The high duty models enjoy most of the features of the standard range of air curtains, in that they retain their elegance and high quality but are more robust and built to offer high performance. Ideal for use in warehouses, petrol / railway stations and general industrial applications. Suitable for a height of up to 4 metres and a width of 2 metres. These units are supplied with hot water coils or electric heaters and are epoxy powder coated RAL 9010. (Other colours are avaliable on request).

These units can reduce energy costs and save money. Like all Air Curtain Design products this range is easy to install and service.
