DUAL OUTPUTINFRARED HEATERS

DU/DUH RANGEAdvanced Radiant Systems’ Dual Output Range (DU/DUH) offers the efficiency benefits of two-stage heating at an economical cost. These units also minimize temperature swings and help avoid system cycling therefore optimizing fuel consumption.

The two-stage units are offered in both the standard grade, DU model, as well as our harsh environment, DUH model.

Model DUHeavy duty industrial/commercial dual output infrared heater with an enclosed burner.

Model DUHIn addition to all the features of the DU, the DUH also includes a potted module, sealed burner housing and heat-treated aluminized tube for harsh environments. Stainless steel available.

The DU/DUH Range gives the system designer the flexibility to meet the changing demands in a given area. Uniform heating and low up front cost make the Dual Output Range one of our most popular models.
