RAPID™ UHD-Series is a duct furnace that is available for burning either natural gas or propane. There is a broad range of options available on both the low-profile (75 - 125) and standard (150 - 400) models, including seperated or non-seperated combustion and stainless steel exchanger configurations. Separated combustion units are suitable for applications where there is contaminant in the air of the heater space. Optional stainless steel heat exchangers provide longer life of the heater with less maintenance. Also, RAPID™ duct furnaces have reliable ignition with direct spark burners.
The low-profile models are ideal for smaller spaces. Installation and operation flexibility with rear or top air and flue connections, are available on the low profile models only. The standard models are ideal for commercial use in warehouses and distribution centers.
