The line of LTU unitized, low-intensity, gas-fired radiant U-tube heaters has been expanded to 19 sizes, ranging in capacity from 40,000 to 250,000 Btuh. According to the manufacturer, these units are especially suited for lower mounting heights of 10 to 20 feet and can be mounted horizontally or up to an angle of 45 degrees. The U-tube heaters have a self-contained draft inducer that pulls combustion products through the combustion chamber for increased radiant efficiency, greater safety, and more uniform tube temperature, says the company. The heaters' U-tube configuration offers a larger radiation surface for more uniform heat distribution at the floor level, states the manufacturer.
