Type Unit heaters
Heat output (W) 30kW-1200kW
 
 
 

Econo-Air SDF/VAV direct-fired variable air volume air heaters allow the volume of heated make-up air to vary depending on the changing requirements of the building or exhaust rates.

The units are fitted with a box burner system, complete with integral fan(s) that ensure the optimum combustion throughout the range of varying volume mains air supply.

Econo-Air SDF/VAV variable air volume air heaters supply 100% fresh air at all times. The volume of fresh air is automatically adjusted by the application of a building pressure sensor or temperature sensors.

Building pressure sensors can be set to maintain either a slightly positive or negative pressure inside the building depending on the requirements of each individual application.

When used for space heating, temperature sensors adjust both the air discharge temperature and the supply air volume to provide a rapid warm up and maintain the minimum stratification levels.

Features and benefits:

  • High efficiency for reduced operating costs
  • Fully modulating bruner with high turn-down ratio (20:1)
  • Close control with rapid response to temperature changes
  • Low maintenance costs
  • Improved indoor air quality
  • Summer fresh air for 'free cooling'
  • Horizontal or vertical units
  • Indoor or fully weather-proofed outdoor units
  • Optional evaporative cooling
