Indirect-Fired Air Handlers

Indirect-Fired Air Handler

Weather-Rite industrial indirect-fired (IDF) air handling units are used to improve air quality by pressurizing an area with conditioned outdoor air, also providing the option to heat, cool and recirculate air. In heating mode, IDF units exhaust by-products of combustion (i.e. carbon monoxide) outside of the heated space. The design of Weather-Rite IDF units offers an energy saving benefit with simplified maintenance. The reduction of electrical use is made possible by a unique single and dual blower/single motor design; with supply parts located outside of the air stream, replacing components is simple.

Additional features of our IDF-Series include:

  • 3,500 to 57,000 CFM
  • Industrial drum and tube heat exchanger
  • Welded unibody construction
  • Upright or horizontal, indoor or outdoor configurations
  • 100% make-up air or re-circulation
  • Evaporative or DX and chilled water cooling available
  • ETL Listed for the United States and Canada

The IDF-Series models are able to suit all application needs. With the availability of upright or horizontal configurations, multiple discharge options, adjustable blower sheaves, fully-assembled and tested power burner with built-in combustion blower, direct expansion (DX) or chilled water cooling coils, various turndown levels and a multitude of other features -- its versatility is sure to meet all requirements.

Available options to suit other applications:

  • All stainless steel heat exchanger construction
  • External spring or neoprene pad vibration isolators
  • Fused disconnect switch (shipped loose or factory-mounted) for single point connection
  • Two-position inlet and discharge dampers to control airflow
  • Mix boxes with Return Air and Inlet Air Dampers
  • Discharge heads and burners to deflect airflow in required direction
  • Inlet hood with bird screen to prevent unwanted entrainment of water and other debris into horizontal unit

Created with a heavy-duty welded structural steel framework and painted, heavy-gauge cabinet panels, IDF air handlers are a long-lasting asset for industrial applications. In an environment that requires cooling and re-circulation, IDF-Series air handlers are ideal for applications involving: processing, automotive, manufacturing, agriculture, dry storage, warehouse, mining, wastewater and water treatment. Whatever your needs may be, Weather-Rite has the appropriate model configuration and capacity.

Whether it's to provide heated air into a manufacturing facility without producing combustion by-products, supplying a wastewater treatment plant with filtered outdoor air or to safely heat a large education facility --Weather-Rite industrial indirect-fired air handlers will provide clean efficient means to heating, cooling and pressurization.
