Invisidor DOORFLOW Air Curtain

Invisidor DOORFLOW Air Curtain

The Invisidor Doorflow Comfort Air Curtain was designed to enhance comfort conditions within commercial environments, from fashionable department stores to universities and colleges. The latest development in a long line of market leading air curtains, the DoorFlow has been developed to be not just of minimalist design but also to minimise maintenance, bringing a continuous and consistent long lasting level of performance and maximize energy savings.

FILTER FREE AIR CURTAIN

The Invisidor DoorFlow uses Biddle’s proven, patented rectifier to supply conditioned air at low speed with minimum turbulence, ensuring the air stream reaches the floor and doesn’t escape to the outside. Comfort within the entrance area is therefore enhanced without any energy wastage.

Features & benefits

  • Minimalist design
  • Filter free
  • Long lasting performance
  • Maintenance-friendly
  • Energy saving Econtrol
  • Performance enhancing patented discharge rectifier

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 doesn’t just offer minimal maintenance but also provides a continuous and consistent long-lasting level of performance.

PATENTED RECTIFIER TECHNOLOGY
So as to minimise turbulence in the discharge airstream, and ensure the air reaches the floor, Biddle have invested heavily in the development of the patented rectifier. This rectifier comprises an optimised number of blades, with a precise relationship between their length and spacing, to create a laminar airstream which reduces turbulence and energy consumption and increases throw for a given air volume.

  • SR Air Curtain

    SR Air Curtain

    SR air curtains are the ideal solution for retailers and other commercial users to combat the issue of climate separation across their outlet or office building doorway. The importance of accessibility to attract customers in the retail sector is well-known, but with this free form of access through ‘open door’ trading, cold draughts and high energy bills are often the consequence.

    INTELLIGENT CONTROL AND REMOTE AIR CURTAIN MONITORING

    The impressive results achieved by the SR are made possible thanks to a combination of four technologies. The revolutionary patented i-sense infrared technology collects all temperature related data in the doorway. CHIPS technology translates this information into the correct setting, whilst the adaptable discharge width (Controlled Air strength technology) and the patented rectifier technology create the perfect climate separation.

    INVISIDOR CITY

    The Invisidor CITY range of air curtains were developed to bring performance benefits and energy and cost savings at a lower installed cost than ever before, being ideally suited to high street stores and other small buildings. Biddle’s CITY incorporates improved structural design and enhanced aesthetic appeal without compromising its award-winning performance.

    Fresh Thinking in Climate Separation
    One of the main functions of an air curtain is to condition outdoor air as it enters the building. For this to be achieved, the airflow must cover the full width of the entrance, so that it cannot be bypassed by incoming air. However, ensuring the airflow reaches the floor level is more difficult, with turbulence at the air outlet being a critical factor.
