Indirect Air Heaters

Our packaged gas fired air heaters deliver clean, hot process air for spray drying applications with air temperatures up to 440°C. We provide robust Concentric and Tubular heaters up to 15MW.

Tubular Type Indirect Fired Air Heater - Features

  • Thermal efficiencies up to 94%
  • Full access for inspection of process air heating elements
  • All surfaces in contact with process air are food grade stainless steel
  • USDA Compliant
  • Process air temperatures up to 430°C (806°F)
  • Process air flow rate up to 220,000kg/h (485,000lb/h)
  • Sanitary conditions, no direct contact between heating medium and process air
  • Low process air side pressure drop ΔP 1.5 – 2.5 kPa - reduced fan power consumption and fan noise levels
  • Orientation: The Air Heater assembly can be configured in line, over/under and LH or RH ‘U’ bend to suit available space. This approach offers great flexibility to fit your plant layout.
  • Designed for Natural Gas, Liquid fuels, Biomass or Coal fired operation
  • Global Service Network for Weishaupt Burners
