Radiant gas heater - VSX20UTE2M | Nortek

U tube heater model concentrates radiant heat to a certain area of the room and not the whole of its space.

Heater design, in particular the fact that the hot air blown into the flue is near the burner, allowed Nortek company to create a unique product - a gas fired radiant tube heater with heat exchanger for recuperation. Technology of forced burner used in Linear models contributed to this, blowing fan is mounted above the burner, the hot air is pushed forward the heater tubes toward the flue. Instead of a direct connection to a flue on heater back, a unique heat exchanger was created. Hot exhaust air flows through it and warms pulled into the burner clean air. Air flows has no direct contact so pulled air is suitable for combustion, it's not pre-polluted.

Combining all of these components Nortek designed VSX unit of the thermal efficiency of up to 90% and radiant up to 65% (~50% on standart units).

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 20 to 50 kW
• All units are CE approved
• NOx emissions as low as 52ppm on certain models – 40% lower than standard radiant heater
• The inclusion of a recuperative heat exchanger on VSX models (patent P308150GB), mounted adjacent to the burner housing, significantly increases thermal efficiencies up to 90% and enhances radiant efficiency above 60%

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.
