SENSAIR Comfort Air Curtain

A NEW WAVE IN CLIMATE SEPARATION SensAir air curtains are the ideal solution for retailers and other end-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. The SensAir technology has been designed to deliver greater comfort for all, whether it is in a supermarket, high street store or office building. The SensAir air curtain does not act...

IMPRESSIVE RESULTS The impressive results achieved by the SensAir are made possible thanks to a combination of four technologies. The revolutionary patented i-sense infrared technology collects all temperaturerelated 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. INTELLIGENT AUTO-ACTIVE CONTROL AND MONITORING The auto-active control is the next generation of controls. Knowing that manual control of air...

i-SENSE INFRARED TECHNOLOGY The patented i-sense infrared technology carefully scans the environment around the doorway collecting information on indoor and outdoor temperatures by measuring the exact temperature at floor level. In addition, the i-sense detects when the door is closed. The i-sense (1) collects temperatures from several points both from inside and outside the doorway (2&3), whilst a sensor in the return air measures room temperature (4). Outdoor and room temperatures are frequently used as a basis upon which automatic control settings are established. The temperature data is provided...

AUTOMATIC CHIPS TECHNOLOGY The Automatic CHIPS control strategy continually monitors and adjusts to provide the most effective and efficient operation by varying the strength and heating independently, to the point on the image below where ‘sufficient heating’ and ‘sufficient strength’ intersect. The SensAir air curtain utilises CHIPS technology to automatically adjust discharge velocity, air volume, discharge temperature and heat output. Outside, return air and discharge temperature sensors are used to determine how much heat is required and the bespoke control algorithm ‘translates’ the data...

RECTIFIER AND CONTROLLED AIR STRENGTH TECHNOLOGY In order to achieve efficient climate separation, Biddle has created two separate technologies. The patented rectifier ensures that the turbulent air from the fans is transformed into a virtually laminar air stream. The air stream reaches the floor with much less air speed than it would in a rectifier-free air curtain, whilst ensuring the discharge air stream stays within the building. Controlled Air strength technology, on the other hand, ensures that the air stream reaches the floor containing the right volume of air, by calibrating air speed...

During installation, an air curtain is typically set to operate at a midspeed setting and rarely adjusted. This results in the air curtain continually operating at a single air volume, velocity and temperature. However, as internal and external conditions constantly vary throughout the day this means the air curtain will only be operating at the optimum setting some of the time and for the rest of the time will be either set too high or too low. The automatic CHIPS (Corrective Heating & Impulse Prediction System) technology ensures the most appropriate setting at any moment in time. The i-sense...

The b-touch control panel has a simple menu structure making it very easy to select preferred settings, such as room temperature and switching the device on/off. Due to the fact the SensAir’s intelligent software is integrated, once the device is installed, it may also function without the b-touch being connected. The b-touch may then be used as a service panel only. The b-touch can also be used as a component of a complete climate system. For instance, the Modbus BMS local operations via the b-touch and central management actively functions simultaneously. A single b-touch can be used to control...

MODBUS COMMUNICATION The SensAir comfort air curtain is easy to connect to a building management system using the standard integrated connection for Modbus communication protocol. Modbus can create communication between several products within the same network. A building management system (BMS) is used for the central monitoring, control and communication between the products and controls present within the building. With the Modbus communication protocol all functions of the SensAir can be monitored and controlled remotely. After installation, interaction with the SensAir is remotely or locally...

O CASING The casing is made of zinc plated sheet steel, and has an inspection panel in the bottom. The inlet grilles are made of anodised aluminium with fixed fins. The inlet module and the end panels as well as the casing are, as a standard, supplied in silver grey (RAL 9006) or traffic white (RAL 9016). The end panels of the white SensAir have a grey inlay. Other RAL casing colour finishes are available for an additional charge. o FAN / MOTOR ASSEMBLY The air curtain is equipped with two or more (depending on type) dual-inlet, vibration free suspended centrifugal fans. Each fan is driven by...
