Value Collection SR3963 Round Silicone Heat Blanket 377W

Product Description

The VALUE COLLECTION SR3963 is a round silicone rubber heat blanket rated at 377 watts and 120 volts, designed to apply consistent, low-profile radiant heat to the exterior of metal containers. The plain back construction allows the blanket to lie flat against cylindrical or flat-bottomed metal surfaces, transferring heat evenly without hot spots. Weighing 13 pounds, this 12-inch diameter unit is built for industrial and process-maintenance applications where controlled external heating is required. Maintenance technicians, plumbers, and process equipment specialists use this type of blanket to maintain fluid viscosity, prevent freezing, or pre-heat materials prior to transfer or use.

This heat blanket is suited for use with metal containers in shop, facility, and field maintenance environments. Typical applications include keeping oils, resins, adhesives, solvents, or other viscous materials at workable temperatures in cold conditions or process workflows. The round form factor and 12-inch diameter make it a practical fit for drum heads, cylindrical tanks, and similarly sized vessels. It operates on standard 120-volt single-phase power, requiring no special transformer or step-down equipment in most North American facilities.

Key Features

• 377-watt output delivers consistent radiant heat across the full 12-inch diameter surface
• Silicone rubber construction withstands elevated temperatures and resists moisture and chemical exposure
• Plain back design ensures full-contact placement against flat or curved metal container surfaces
• Operates on 120-volt standard power with no additional voltage conversion required
• Round shape sized for drum heads, tank ends, and similarly dimensioned metal vessels

Compatibility

Designed for use with metal containers requiring external surface heating. No specific OEM container models or system families were identified in the product data.

Installation Notes

Installation should be performed by a qualified maintenance technician or electrician familiar with low-voltage resistive heating equipment. Always ensure the power supply is de-energized before positioning or repositioning the blanket on the container surface. Secure the blanket firmly against the metal surface to maintain full thermal contact and prevent localized overheating. Verify that the supply circuit rating is adequate for the 377-watt load before energizing, and follow applicable NEC guidelines for resistive heating equipment.
