When it came to specifying a state of the art heating system for the hangars at the new flagship RAF Northolt site, there was only one choice – Nor-Ray-Vac continuous radiant tube heating from AmbiRad. Used extensively across many new and existing RAF sites, it is a proven, highly efficient system that promises considerable cost savings over its lifecycle.
The installation is part of the Ministry of Defence Estate’s Project MoDEL – a massive £180million investment and restructuring scheme to create a world class 21st Century ‘anchor site’ in London.
The redesigned RAF Northolt includes five new hangars. Four of these, each measuring 38m x 36m were fitted with six 38LR Nor-Ray-Vac burners, designed in two temperature zones. The fifth hangar, measuring 42m x40m and known as the ‘workshop hangar’, is heated by six 46LR burners, again designed in two temperature zones.
Offering blanket heat coverage, the Nor-Ray-Vac system ensures the hangars are flexible in use, from housing small/medium sized fixed wing aircraft to helicopters. Ducted fresh air is supplied to the burners and radiant branch end vents to comply with the Crown Fire Standards for operational aircraft hangars.
Because the system doesn’t heat the air, the primary heat source is maintained whenever the vast hangar doors are opened. This ensures the hangar remains a comfortable place for personnel to work at all times, without the energy demands of heating the space after a sudden temperature drop.
Zone heating also allows the space within each hangar to be sectioned off, should a different temperature only be needed for part of it. This means using a fraction of the energy required to warm the entire hangar. With the system’s impressive 92% energy efficiency, it is a flexible solution that keeps heating costs to an absolute minimum.
