Hitco’s HVAC heaters can be used in applications to heat air and gases and are available in three types of fittings: 

• Flanged fitting- In flanged fitting tubular heaters are welded/ brazed or fitted on a flange and the flange in turn can be placed in the opening provided in the duct.
• Modular Duct heater- Tubular elements are fitted directly in a modular duct thereby reducing the effort and down time caused by replacing and removing the flanged heater from the duct.
• Finned tube duct heaters: finned tubular heater can also be provided in flanged or modular duct fitting. These are duct heaters comprising of bundled finned tubular heater. In this heater Fins are wound on the tubular heaters so as to provide higher surface area for the air to come in contact with thereby increasing the efficiency of the air or gas heating.
