The Biddle IndAC2 industrial air curtain, is the perfect solution for separating climates in industrial buildings. Doors are often open for long periods of time to facilitate transport in and out of the building. The IndAC2 air curtain can be used for climate separation between indoor and outdoor environments and for indoor climate separation between two spaces with different temperatures.

Open doors cause energy loss and disturb the inside climate; the difference between the inside and outside temperature leads to an exchange of air, resulting in cold air entering and warm, heated air, flowing out. When the IndAC2 air curtain is mounted above or next to an open door it provides a very efficient climate separation at the lowest energy consumption. The comfort of staff operating near the door is improved by heating the cold incoming air through the air curtain, thus preventing draught. A corridor might seem like a relatively cheap option, but it can hinder traffic and make stock...

With the automatic control option fitted, the IndAC2 continuously selects the correct settings. Once the air curtain is installed and commissioned the user does not have to worry about the settings, as the output of the IndAC2 will adjust to meet the challenges of the environment. Sensors ensure that the IndAC2 is supplied with all details regarding the climate outside and inside near the doorway. All the information is continuously translated by the CHIPS technology into the correct setting of the air curtain. The temperature and fan speed of the IndAC2 are automatically adjusted, which means...

IMPRESSIVE TECHNOLOGY CHIPS With changing weather conditions and insufficient attention to or knowledge of an air curtain, it can be the case that an air curtain is not set up correctly. It can either blow too strong or too weak, with a discharge temperature that is too high or it is not switched on at all. Energy loss is a result with low comfort (draught) and an unnecessarily high noise level. Biddle has developed the fully automatic and energy saving CHIPS-technology to save energy and provide a high level of comfort. The CHIPS-technology adjusts the discharge temperature and the strength...

O PATENTED DOUBLE RECTIFIER Whilst developing the IndAC2, Biddle chose to use the well known outlet discharge pattern, the Double Rectifier. The IndAC2 is equipped with radial backward curved fans which homogeneously distribute the air across the whole discharge opening, producing high efficiency and comfort levels. If a conventional industrial air curtain without a rectifier discharges air at the same velocity as a unit with a Double Rectifier, the downward penetration is tangibly less. The air stream does not reach the floor, and the open door is not covered off properly. Consequences include...

The IndAC2 air curtain can come with a basic control option or the b-touch control. OlACCURATE stepless CONTROL The b-control is a 0-10V potentiometer that functions stepless and makes it easy to manually set the air curtain accurately to the desired fan speed. To be assured of the best possible climate separation the manual setting should be adjusted to circumstances several times a day. (■AUTOMATIC on and off Use of the optional door contact switch enables the IndAC2 to be automatically switched on when the door opens and off when the door is closed. qIenergy saving The IndAC2 is standard equipped...

OllndAC2 ST: 3-6m OllndAC2 MX: 5-8m LENGTHS OllndAC2 ST: 150, 200 and 250cm OllndAC2 MX: 150 and 225cm MOUNTING IndAC2 air curtains in combination with an automatic control can be installed directly above the door. IndAC2 with basic control can also be installed next to the door....

INSTALLATION The available room layout around a door determines where and how an air curtain can be best installed. Thanks to a diverse range of installation positions, the IndAC2 air curtain can be matched to the constructional possibilities offered by the local situation. Depending on the situation, the air curtain is either installed horizontally above or vertically next to the door, covering the full length or width of the doorway. For the vertical position there are two options: square to the wall and parallel to the wall. The unit should always be positioned as close to the door as possible....

O CASING The casing and the inlet grille are manufactured from zinc-plated sheet steel, strengthened to minimise deformations and vibrations, and have a full-polyester powder coating. The IndAC2 is supplied in two colour combinations: RAL 5011/RAL 9006 and fully RAL 9006. Other colours are available on request. The radial backward curved fans are mounted in the casing such that they cause no vibration. Each fan is driven by a rotor motor with EC technology. The fan casing are manufactured from aluminium and the impeller is made of plastic. The motor of the IndAC2 is protected against overheating....
