Sofia Airport

In 2006 Sofia Airport celebrated its 70th anniversary. Also this year the Terminal 2 was finally equipped with DEVI electrical heating solutions and opened for new clients. With annual capacity of 2.6 million passengers, Terminal 2 was designed to allow a future extension to meet growing requirements of the fast developing air traffic.

The central building of Terminal 2 has 56 850 m².  The access to the eight levels of the terminal building is facilitated by 12 elevators and 7 escalators. A passageway connects the halls to the 800-space parking garage.

Heating cables
DEVIflex™ is an extremely high-quality, 360° fully screened twin conductor cable with a tough outer sheath (non UV stable). Its round profile and robust construction ensures a fast, simple and safe installation in multiple indoor floor constructions and pipe tracing applications.
The DEVIreg™ 330 is an electronic thermostat to be installed in electric cabinets with DIN rail attachment. Used primarily for controlling a lower temperature range as by frost protection. The thermostat must be installed via an all-pole disconnection switch and has a LED indicating the current mode (heating, standby or fault). To measure and control the desired temperature a wire sensor or an outdoor air sensor must be used. The temperature setting can be adjusted with a scale from -10°C to +10°C.
The DEVIreg™ 850 is an advanced thermostat with LED display used for outdoor ground or roof applications. The sensors provide information about both moisture level and temperature, resulting in an optimal control of the heating system. The system can be set up in three ways; as a single system for roof or ground (1 to 4 sensors), as a dual system for roof or ground (2 - 4 sensors) or as a combination system for roof and ground (2 - 4 sensors). In the dual / combination systems it is possible to prioritize between the zones, e.g. if only a limited power output is available.
