AR Series
 

 
  AR heaters are now considered the generic radiant tube heater within the market place. They offer an outstanding reputation for combining efficiency, economy and low noise operation. They are ideal for heating factories, warehouses and workshops - indeed any industrial or commercial premises whether old or new that requires effective, efficient heating with low running costs.


The AR range has an advanced slim burner assembly that incorporates two compartments. One houses the combustion chamber with a specially constructed air flow passage and burner head to eliminate combustion air turbulence and flame roar. The other contains the twin gas safety shut off valve and airflow proving switch that monitors the differential air pressure within the burner for enhanced safety of the heater.

The AR range is available in 'U'-tube, linear, double linear and herringbone manifold configurations.
Ambi-Rad gas fired AR heaters are manufactured from the finest materials including stainless steel reflectors, end caps, turbulators and guarded air inlet cover. Emitter tubes are CALCOAT® (heat treated aluminised steel) or stainless steel depending on the model.





AR SERIES - Benefits

  Reduces running costs. Savings of between 25-60% of fuel costs can be achieved
  Provides even heat coverage at low level
  Does not directly heat the air - ideal in areas of high air infiltration
  Minimises roof heat losses - reduced stratification
  Systems can be controlled easily to provide varying zoned temperatures and operating times
  Provides rapid heating up times
  Easy to install and maintain


APPLICATIONS

  Factories
  Foundries
  Engineering Workshops
  Warehouses
  Retail Outlets
  Aircraft Hangars
  Vehicle Distribution Centres
  Vehicle Workshops
  Glasshouses
  Sport Arenas
  Museums


SYSTEM DESIGN

The AR series offers the consultant the widest range of burner inputs possible in designing the heating requirements of any industrial or commercial building.

However, it is recommended as a good practice that the large kW burners are not mounted at low level and particular care is taken to ensure adequate heat coverage is provided when specifying these higher rated burners.
