U tube heater model concentrates radiant heat to a certain area of the room and not the whole of its space. Units available in two versions:

  • VSUT - equipped with stainless steel reflectors and reflector end caps
  • VSAUT - equipped with aluminized steel reflectors without reflector end caps, cheaper version

Introduction

Renowned for its pioneering track record, AmbiRad, 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 16 to 48 kW
  • All units are CE approved
  • NOx emissions as low as 52ppm on certain models – 40% lower than standard radiant heater

ConstructionVision radiant heaters constructions

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 AmbiRad ‘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, AmbiRad 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.

Benefits of radiant tube heating

  • Greater Comfort, “sandwiched” between a warm floor below and low intensity span above
  • Increased Efficiency, heat “work zone” not ceiling. Not increasing heat transfer by “scrubbing” building envelope with moving air
  • Faster Recovery when doors open/close, due to heat “reservoir” in the mass of the floor
  • Now Ambi-Rad Improves on a proven concept

Properties of radiant heat

  • Emitted by hot surfaces
  • Travels in straight lines
  • Passes through the air without heating it
  • Absorbed by cooler solid objects on which it falls

Applications

  • Aircraft hangars
  • Automotive workshops and showrooms
  • Factories
  • Retail outlets
  • Sports arenas and halls
  • Warehouses
  • Workshops

Optimum economy and fuel savings

  • The elimination of both distribution and standby losses coupled with high operational efficiencies at the point of use enable fuel savings of up to 65% compared with conventional heating systems.
  • Excellent radiant performance. More of the available heat generated is distributed to floor level thereby improving efficiency and reducing energy consumption.
