The Christchurch International Airport

DEVI provides safety during the winter for Christchurch Airport, New Zealand.

The Christchurch Airport is the 2nd busiest airport in New Zealand and it acts as the main air-traffic gateway to the popular South Island for domestic and international tourism and trade. Due to its increasing numbers of passengers, the airport has completed construction of a major terminal upgrade.

At 43.5 degrees south and just 3,800 km from Scott’s Antarctic base, winter in Christchurch regularly delivers frost and snow. For such a busy airport, safety during the winter is crucial. In order to reduce any hazards that may be caused by winter conditions, a DEVI electrical heating solution was installed during the Christchurch Airport redevelopment.  

This DEVI electrical heating solution provides safety to the exposed vehicle ramps of the multi-story parking building and the exterior doorway paving of the domestic and the international terminals.

Thermostats
Backend.Models.ProductViewModel.Title
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.
Heating cables
Backend.Models.ProductViewModel.Title
DEVIsnow™ is an extremely high-quality, 360° fully screened twin conductor cable with a tough outer sheath (UV stable). Its round profile and robust construction ensures a fast, simple and safe installation on roofs, in gutters, down drain pipes and on the ground. The cold lead has solid conductors ensuring fast installation with a clearly visible connection. To ensure a long life-time, all cables are minutely inspected including tests for Ohmic resistance, high voltage and material controls to ensure the quality. This means that we are proud to supply our extended DEVIwarranty™.
