Detroit Radiant – Universal Ray, RH Series 75,000 BTU Natural Gas Infrared Tube Heaters – 20 FT Hot Rolled Steel
Simple. Efficient. Durable.
RH Series 75,000 BTU Natural Gas infrared tube heaters deliver reliable, Single-Stage radiant heat for commercial and industrial environments where efficiency, durability, and simplicity matter. Designed to heat people and surfaces directly, RH Series heaters minimize wasted energy from air stratification and provide consistent comfort in large or high-ceiling spaces.
This RH Series 20-foot infrared tube heater pairs a 75,000 BTU Single-Stage Natural Gas burner with a full Hot Rolled steel tube assembly to produce steady, even radiant heat across the occupied zone. The black-coated Hot Rolled steel tubing offers excellent corrosion resistance while maintaining strong heat transfer performance—making it a dependable choice for warehouses, workshops, service bays, manufacturing facilities, and agricultural buildings.
Built with RH Series commercial-grade components, these heaters feature direct spark ignition, a single pressure switch design, and polished aluminum reflectors that focus infrared energy downward where it’s needed most. The result is a rugged, easy-to-operate radiant heating solution engineered for long service life in demanding non-residential applications.
