Value Collection SR3945 Round Silicone Rubber Heat Blanket

Product Description

The VALUE COLLECTION SR3945 is a round silicone rubber heat blanket rated at 18 watts and 120 volts, designed to apply low-level surface heat to metal containers. The plain back construction sits flat against the container wall, providing consistent thermal contact without the need for additional mounting hardware. HVAC technicians, plumbers, and industrial maintenance professionals use this style of heat blanket to prevent fluid freezing, maintain viscosity, or keep process materials within a required temperature range. The 3-inch diameter makes it well suited for small metal vessels and cylindrical containers where localized heating is needed.

This heat blanket is intended for use on metal containers in light industrial, mechanical, and facilities maintenance applications. The 120-volt input means it connects directly to a standard single-phase circuit without a transformer or step-down device. It is commonly installed on small tanks, reservoirs, pipes, and canisters where a compact round form factor fits the contact surface. The silicone rubber construction resists moisture, oil, and moderate chemical exposure, making it appropriate for service environments where exposure to shop fluids or outdoor conditions is a factor.

Key Features

• Round silicone rubber construction provides flexible, conforming contact with curved metal surfaces
• 18-watt output delivers controlled, low-intensity surface heat suitable for freeze protection and viscosity maintenance
• 120-volt input connects to standard single-phase power without additional electrical components
• Plain back design lays flat against the container surface for direct thermal transfer
• 3-inch diameter fits small metal containers, reservoirs, and cylindrical vessels
• Silicone rubber material offers resistance to moisture, oils, and moderate chemical exposure

Compatibility

Designed for use with metal containers requiring localized surface heating. No specific compatible model numbers or system families are identified in the product data.

Installation Notes

Installation should be performed by a qualified electrician or maintenance technician familiar with low-voltage heating equipment and applicable NEC requirements. Disconnect and lock out power to the circuit before handling the blanket or making wiring connections. Ensure the metal container surface is clean and dry before applying the blanket to maximize thermal contact. Do not energize the blanket while it is folded, bunched, or separated from the container surface.
