Eight models of PTS/PTU Series tube heaters are available in over 100 configurations in capacities ranging from 40,000-200,000 Btuh and minimum mounting heights from 10 to 18 feet. The positive-pressure low-intensity tube heaters incorporate a patent-pending innovative Tube Integrity Safety System™ (TISS) that provides additional safety for building owners and gives them peace of mind, says the company. The low-voltage circuit TISS continuously monitors the clearance between the top of the reflector and the ceiling for excessive heat and tube integrity compromise. If the heat increases due to the unlikely event of heat exchanger failure, the wire melts, the safety circuit is broken and the gas controls shut down, the company says. The PTS/PTU tube heaters are designed for use mainly in complete building heating. The PTS Series heaters are available in straight, L-shaped, Z-shaped or expanded U-shaped configurations. The PTU Series heaters, designed to use for high heat loss areas and spot heating, are available in seven different “U” shaped configurations.
