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.

Power: 120, 240 and 480 V (contact OMEGALUX™ for 480 V heaters)

Are these blanket coda approved for use in Canadian offshore applications 

Asked by: Eddy
The Heaters have many approvals detailed in the bullets of the product and data sheets. Unfortunately CODA approval is not one of them so you would need to research to see if any of the existing approvals crossover to CODA's requirements.
