Explosion Proof Unit Heaters

Industry's Lowest Ignition Temperature Code Rating : T3C, 320°F (160°C)
Dual Over temperature Protection: With both automatic and manual reset over temperature cutouts for additional safety.
Nontoxic Propylene Glycol Heat Transfer Fluid
Low 70 PSIG Relief Valve Setting : This assures that in an emergency, the initial escaping vapor temperature remains below the 320°F (160°C) ignition temperature.
Corrosive Resistant Options : Offered are three constructions suitable for most applications. Standard construction for use in dry non-corrosive areas includes : Welded steel heat exchanger; powder-coated cabinet; epoxy-coated motor. A 316 stainless steel construction suitable for Waste Water Treatment Plants includes : 316 stainless steel heat exchanger, headers and tubes with aluminum fins; stainless steel cabinet; corrosive resistance hardware; epoxy-coated motor. Third construction is suitable for use in Chemical Plants where chlorides are present and includes : corrosive resistance hardware; epoxy-coated motor.

Explosion Proof Convectoin Heaters

Designed to provide a heavy duty and corrosion resistant heat source. Features include:

Wide Selection of Sizes: Four compact sizes to fit any space with ratings from 500 to 9500 watts.

Sloped Top Cabinet: Prevents objects from being set on top of the convector, which can restrict airflow and cause overheating.

Single and Three-Phase: Unique design provides single and balanced three-phase loads in a single element.

Gas and Dust Atmospheres: Three listings cover the entire field, two for hazardous gases and vapors and one for dust particles.

Wet Locations: All unit sizes available with iridite-coated elements and powder-coated frames for NEMA 3 wet locations.

Explosion Proof Unit Heaters (Compact)

Designed with both size and economy in mind. Compact advantages and unique features include :

Compact Size : This small design is only 13 inches wide, which makes it ideal for applications where limited space is available.
Low Cost : The Compact design offers the most economical solution for heating small Class I, Group D hazardous areas. It is a cost effective alternative to the use of explosion-proof convection heaters.
Redundant Over temperature Protection : Primary and secondary automatic reset thermal cutouts for additional safety.
Stainless Steel Construction : Provides superior corrosion resistant protection. Optional Dirty Duty construction adds epoxy coating to all aluminum parts for use in corrosive applications.
Optional Marine Duty Construction : The Compact design is ideal for shipboard use where size, weight and corrosion resistant construction are critical.
