OMEGALUX™ silicone rubber area
drum heaters are low-watt density
electrical resistance heaters in
blanket form. They are designed to
provide a practical, efficient means
of freeze protection, viscosity
control, melting of solids, and
maintaining materials at elevated
temperatures in Class I, Division
2 areas.
OMEGALUX™ SEPDH drum heaters
feature built-in high-limit thermal
cutout protection, which, in the event
of a primary temperature controller
failure, maintains heater sheath
temperature below the minimum
safe auto-ignition temperature of the
material being heated or materials in
the area. OMEGALUX™ SEPDH drum
heaters are compatible with most
chemical fluids and oils used in field
service. Unlike many other drum
heaters, the SEPDH has a thin-line
design that lets it fit between the
drum and the cradle.

† Price are shown in RMB.
Note: * Insert “High-Limit Thermostat Temperature” rating from above table. The maximum allowable sheath temperature (“T” rating) must be specified if drum heater is to be used in a Division 2 area. “C” specifies heaters with adjustable temperature control assembly and temperature ranges from -4 to 163°C (25 to 325°F).
** Article 501 of the NEC requires that the maximum sheath temperature of the heater shall not exceed 80 percent of the auto-ignition temperature of the surrounding atmosphere when heater is continuously energized.
Auto-Ignition Temperature: The minimum temperature required to initiate or cause selfsustained combustion of a solid, liquid or gas independently of the heating or heated element (see NFPA 325M, Fire Hazard Properties of Flammable Liquids, Gases, and Volatile Solids).
Ordering Example: (1) SEPDH-C-1300-120-T3 55 gallon, 120 V drum heater with a T3 rating of 156°C (312°F), ¥23,170.00
