Radiant gas heater - VS50LIE16 | Nortek

Linear heater model evenly distributes radiated heat by the entire floor area below. Units available in four versions:

• VSLF - blowing fan is mounted above the forced burner, the hot air is pushed forward the heater tubes to the flue pipe. This results in much more convenient and less expensive heater service and installation, no need to do additional wiring toward the fan. This model comes with a stainless steel reflectors and reflector end caps.
• VSLI - exhaust fan is mounted at the end of the heater on the opposite side of the induced burner, the hot air is pulled via heater tubes toward the fan which connects to flue. This model maintenance and installation is not as convenient as VSLF, but in case of damaged heater tubes it's preventing gas combustion products from entering the premises. This model comes with a stainless steel reflectors and reflector end caps.
• VSALF - same as VSLF, the only difference is that it's equipped with aluminized steel reflectors without reflector end caps, cheaper version.
• VSALI - same as VSLI, the only difference is that it's equipped with aluminized steel reflectors without reflector end caps, cheaper version.

Introduction

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.

New advanced burner technology

• New slim-line burner head provides a long evenly distributed flame that dramatically improves temperature distribution along the entire length of the heater, delivering a more even floor coverage
• Combustion occurs entirely within the firing tube. Not only does this reduce the size and weight of the traditional burner control housing but it also helps to reduce noise levels (as quiet as 47 dB(A) 3m free field)
• Choice of burner ratings from 14 to 50 kW
• All units are CE approved
• NOx emissions as low as 52ppm on certain models – 40% lower than standard radiant heater

Construction

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).

Additional control at the touch of a button

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.

Radiant Heating

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.

Universal Application

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.
