Compact 22kW U-Tube Gas Radiant Heater for Industrial and Warehouse Heating
The Powrmatic SRP PU20US is a gas-fired U-tube radiant heater designed to provide efficient infrared heating for industrial buildings, workshops and warehouse environments. With a heat input of 22kW, this compact model is well suited to applications where effective zoned heating is required but available installation length is more limited than with linear radiant tube heaters.
Using infrared radiant heating technology, the PU20US warms people, machinery and floor surfaces directly rather than heating the surrounding air volume. This improves comfort while reducing heat stratification in buildings with high ceilings or frequent door openings, helping to maintain more effective heating performance in demanding industrial settings.
The U-tube configuration allows a shorter overall installed footprint while still delivering strong radiant coverage into the occupied zone. Combined with the high-efficiency aluminium reflector and gas-fired burner assembly, the heater provides reliable and focused heating performance for warehouses, workshops and commercial spaces requiring dependable overhead radiant heat.
Supplied with the MC200 optimised digital controller, the PU20US offers improved temperature management and efficient day-to-day operation for professional installations.
