Ultra-Safe EXP offers an ignition temperature code rating of T3C, or 320°F (160°C), and dual overtemperature protection with both automatic and manual reset overtemperature cutouts. A 70 psig relief-valve setting ensures that in an emergency, the initial escaping vapor temperature remains below 320°F (160°C). Standard construction of the explosionproof unit heater for use in dry, non-corrosive areas includes a welded steel heat exchanger and a powder-coated cabinet. For chemical plants where chlorides are present, the units include a Heresite-coated heat exchanger, cabinet, fan blade and corrosion-resistant hardware.
