﻿Air curtains are designed for minimal maintenance
Biddle’s Invisidor Doorflow range of air curtains has been designed to minimise maintenance. The need for filters is eliminated by a purpose-designed coil/heater battery to reduced the build-up of dust and debris between the coil fins. They can be free hanging, recessed or cassette style. Heat outputs are up to 25 kW when installed up to 3.1 m high.
Available in a variety of paint finishes, these door curtains have a minimalist style that is designed to look good in all types of entrances. Their modular nature enables units to be joined to create a seamless air curtain for any door width.
These air curtains use Biddle’s patented rectifier to supply conditioned air at low speed with minimum turbulence, ensuring the airstream reaches the floor and does not escape to the outside. Heating can be provided by hot water or electricity.
The Encontrol controller reduces energy consumption by controlling comfort by adjusting air volume and temperature.
