High Capacity 50kW U-Tube Gas Radiant Heater for Industrial and Warehouse Heating
The Powrmatic SRP PU50 is a high-output U-tube gas radiant heater designed to deliver efficient infrared heating for warehouses, factories and large industrial environments. With a heat input of 50 kW, this heater provides strong radiant heat coverage while maintaining a more compact installation footprint compared with longer linear radiant tube systems.
Using advanced infrared radiant heating technology, the PU50 warms people, equipment and floor surfaces directly rather than heating the surrounding air volume. This approach improves heating efficiency and reduces heat stratification in buildings with high ceilings or frequent door openings such as loading bays and distribution centres.
The U-tube emitter configuration provides effective radiant heat distribution while keeping the installed length manageable for industrial buildings with structural limitations. Combined with the high-efficiency aluminium reflector and gas burner system, the heater directs radiant heat precisely into the occupied workspace, delivering consistent and reliable heating performance.
Supplied with the MC200 optimised digital controller, the PU50 allows installers to implement accurate temperature control and improved energy management within industrial heating systems.
