OMEGALUX™ silicone rubber heavy-duty heating blankets feature built-in high-limit thermal cutout protection, which, in the event of a primary temperature controller failure, maintains blanket sheath temperature below the minimum safe auto-ignition temperature of the material being heated or materials in the area. (“T Rating” in the National Electric Code, Section 500.)

OMEGALUX™ SEPHB Series blankets are flexible and readily conform to most plane and simple curved surfaces. Blankets are easy to install with optional factory applied pressure-sensitive adhesive, creating a permanent bond.

OMEGALUX™ SEPHB blankets are compatible with most chemical fluids and oils commonly encountered in field service. They are exceptionally resistant to weather, moisture, and effects of sunlight, and ozone gases, and they can be used in areas of high radioactivity.

Note: 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).
