Hassle Free Comfort 1 Energy Saving Hi'l llit'll 3 Ceiling Recessed Units 9 Wiring Schematic & Controls 13 Materials, Components & Hassle Free Comfort The latest development in a long line of market leading air curtains, Invisidor DOORFLOW, has been developed to be not just of a minimalist design but also to minimise maintenance, bring a continuous and consistent long lasting level of performance and maximise energy savings. • Minimalist design • Long lasting performance • Energy saving ECONTROL • Performance enhancing patented discharge rectifier • Choice of RAL paint colours • Water or...

Minimal Maintenance, Long Lasting Performance Air curtains are acknowledged to enhance comfort conditions in the entrance environment. However with routine maintenance procedures, such as cleaning filters, often ignored a drop-off in performance and an increase in noise all too often results. With this in mind the Invisidor DOORFLOW has been carefully developed to minimise maintenance. A purpose designed coil/heater battery reduces the build-up of dust and debris between the coil fins to such an extent that filters are no longer necessary. Having no filters means the Invisidor DOORFLOW...

Energy Saving The new ECONTROL will ensure air curtain performance is optimised whilst minimising energy usage. Connecting the ECONTROL to the Invisidor DOORFLOW couldn't be easier - just plug one end of the cable in to the air curtain and the other end into the controller. In 'Auto' mode ECONTROL will automatically adjust the air curtain's heat output to optimise air curtain performance, control the space at the selected set point temperature (range = 18-25°C) and minimise energy usage. In 'Manual' mode ECONTROL simply provides the air curtain with either half heat Regardless of whether...

Circular Doorways When an air curtain is to be used in conjunction with revolving doors or any other form of circular doorway we are able to use a variant of the recessed model installed either adjacent to or directly above the door. Given certain key dimensions we manufacture a bespoke discharge grille to fit perfectly with the curvature of the door, and ensure optimum climate separation around the circular doorway. Installation & Maintenance Units can be specified for free-hanging, cassette or recessed installation and all are compatible with universal fixing systems, allowing...

Wiring Schematic Low voltage cable, supplied by Biddle Plug ECONTROL energy saving -' controller into either socket - external on exposed and ceiling recessed styles, internal on cassette style Controls Schematic External Control Connections A volt free BMS enable contact (INHIBIT) is included on each unit as standard. If the terminal is linked the unit will run. If it is open circuit across the terminal the unit will switch off. Remote Heating Control via BMS To facilitate fan only operation (i.e. no heating) a 3.3ko resistance should be wired across the INHIBIT terminal. Fault Output...

Materials, Components & Control & Operation By adjusting heat output and fan speed the ECONTROL ensures air curtain performance is optimised whilst minimising energy usage. It is connected to the unit by a low voltage data cable with a RJ4/4 plug on both ends. Multiple units are also connected in this way. Electrical Connections LPHW units are connected to the mains supply by a 2 metre cable. The 3-phase mains supply cable used with electric heated units enters the air curtain via a cable gland on top of the unit and is then connected to a terminal strip within the unit. The water...
