Liebherr’s British HQ heated by continuous radiant tubes

Space heating for the 18 m-high 5000 m2 factory of Liebherr-Great Britain at Biggleswade is provided by a Nor-Ray-Vac continuous-radiant-tube system designed by Ambi-Rad. Equipment in the building, in which cranes, earthmovers and concrete truck mixers are made, includes overhead cranes with a capacity of 25 t and the UK’s biggest rolling road for mobile cranes. To provide even heat coverage throughout the main assembly part of the building, 14 burners of 46 kW and three of 38 kW were mounted 15.3 m above floor level. In the vehicle cleaning areas, two U-tube radiant heaters were installed; this model is suitable for car-wash environments, where water could be dangerous to standard radiant tubes. Additional heating for the welding bay is provided by four wall-mounted radiant-plaque heaters. For economy of operation, the main system is divided into four separately controlled zones. Radiant-tube heating is cost effective in such large buildings because energy is not used heating a vast volume of air. Only people and objects are warmed, and all the heat is focused at the lowest 2 m, where it is most needed by people working in the premises. The system was installed by Mitie Engineer Service’s south-east region.
