Outside doors of shops and public buildings can be left open for various reasons. An open door of a shop arouses the curiosity and passers-by will walk in freely, which means that more people will examine and buy the merchandise. An open door makes a public building more easily accessible to people, which contributes to a customer-friendly approach. When the door is open, colder outside air will disturb the indoor climate. Staff will fall ill and customers will not feel very comfortable. All this can soon lead to loss of turnover. An open door attracts people into the shop. Fig.1: Open door...

Advantages of model SF: In case an air curtain with rectifi er is used, the heat loss will be limited to thelargest possible extent. Warm air will stay in and incoming cold air will be Compact and solid unit Օ Easy installation and low maintenance conditioned. Research by TNO (Dutch organisation for Applied Scientifi c Reseach) For many applications has shown that a Biddle air curtain diminishes the outfl ow of air from the building. About 90% of its heating capacity comes to the benefi t of the indoor climate. Thanks to this high effi ciency, Biddle air curtains provide the best solution...

Type code The Biddle air curtain, model SF, has been designed as a universal air curtain above doors of any width, but no higher than 3.0 m*. Model SF is available as a free- hanging model in three widths: 100, 150 and 200 cm. By mounting multiple units side by side, an air curtain can be created for any possible door width.

Depending on the situation the air curtain can be controlled in two ways: 1. Thermostatic controller 2. Three-speed switch > i -E) as well as for the water-heated unit (SF i -W) with corresponding Siemens CH-water control. The discharge temperature of the air curtain depends on the heating level, the air inlet (= room) temperature, and the air displacement. The discharge temperature is limited to 40C. The air curtain comes standard with an interface and a thermostatic controller. The controller allows the user to switch the air curtain On and Off and to control the strength (air...

The casing is made of 0.9 mm zinc plated steel, reinforced to eliminate vibration, and it has an inspection panel at the bottom. In the synthetic air inlet grilles, anodised aluminium grilles with fi xed fi ns are mounted. The casing is available in the colour white RAL 9010 or 9006 (other RAL colours are available at an extra charge). > Three-way valve for connection to control panel (Siemens- standard) Fixed outlet temperature,three-way valve This two-row heating coil is made up of 3/8" copper pipes with aluminium fi ns for optimal heat exchange.
