Double linear model evenly distributes radiated heat throughout the floor area of the large-sized rooms. The heater models are twice as long and more powerful than the standard linear model. The unit has two burners that are installed at both ends of the tube and only one extraction fan in the middle of the device. Such a device is less expensive than two standard Linear heaters. Units are available in two versions:
Renowned for its pioneering track record, Nortek, Europe’s leading supplier of radiant tube heating systems, has yet again raised the industry standard in terms of innovation and technical performance.
The range of high efficiency Vision radiant tube heaters delivers exceptional performance in terms of efficiency and the potential to reduce energy costs.
The foundation of this development is a high efficiency advanced burner.
Bolt in place brackets for safe secure reflector fixing.
Ideal in any application where a secure system is required, such as - wind exposure around overhead doors or hangar doors (walls).
All models are compatible with Nortek ‘SmartCom3’ control systems. SmartCom3 units incorporate a host of features such as self-learning optimised start-up to ensure increased comfort and energy savings.
Working in the same way as the sun, radiant heat warms all solid objects and surfaces in its path through electromagnetic waves. Being mounted overhead, Nortek radiant heaters produce infrared heat that is directed downwards to low level by a reflector.
Infrared energy passes inertly through the air, dissipating as heat upon contact with people and surfaces thus creating a comfortable, all-round radiant warmth at lower air temperature. This reduces wasteful heating of empty space and makes substantial energy savings over conventional boiler and air systems.
Radiant heating has traditionally been predominant in industrial and commercial buildings, especially where there are large, high bay areas or where there are a high number of air changes within the environment.
Vision has been developed with these markets in mind and with a view to making radiant heating truly competitive within new smaller industrial and commercial buildings.
Its application is universal including environments with high air change, frequently opened doors, or where there is a need for zonal heating in very large premises.
The highly efficient performance of Vision provides greatly reduced running costs and improved capital payback, setting new industry standards.
