Flexible Heaters for Protection against Freezing Temperatures

This post will explain the usage of flexible heaters or silicon rubber heaters to protect the fuel (diesel) against freezing temperatures. These heaters may be wrapped around the fuel container.

What’s the Purpose of Preventing Fuel from Freezing?

When exposed to freezing conditions, the diesel fuel stored in the aluminum fuel tanks for various industrial applications must be maintained at a temperature above freezing.

The reason is that when temperatures dip below the freezing point or lower, diesel fuel inside the aluminum fuel tanks begins to behave in an undesirable manner. Furthermore, the paraffin wax that is included inside the fuel will start to form solid molecular bonds. As the number rises, these bonds become more noticeable, which gives the fuel a dirty look.

In typical circumstances, the paraffin wax functions as a lubricant to keep the fuel at the appropriate viscosity level. When extra wax hardens over time, it has the potential to clog a fuel filter, which would prevent fuel from reaching the engine. You can probably imagine this will lead to a malfunctioning engine since it will be deprived of fuel.

Flexible Heaters That Are Designed Professionally

As a solution, Rama Corporation designs flexible heaters such as silicone rubber heaters and other types of heaters made of flexible materials. But most of the time, our products are included in the production process of a third-party manufacturer in charge of product design.

The most significant advantages include that the heaters are small and simple to set up and maintain a temperature below a certain threshold. In most situations, the end user does not remove the heating elements; this is only done if the heater is malfunctioning. When it comes to our service, we experience an exceptionally low percentage of malfunctions.

The following are included as features of the flexible heater design:

• Stainless steel plates that have been vulcanized at the factory; these plates could then be readily affixed to and detached from aluminum fuel tanks.
• To prevent the temperatures from rising to unsafe levels, flexible heaters at Rama Corporation are manufactured with a certain watt density.
• An insulator made of a silicone sponge is employed to direct the heat toward the tank.
• A stable electrical connection (plug and socked) is utilized to make the process of providing power to the equipment simple and uncomplicated.
• The sheath (outer coating) is made of fiberglass-reinforced silicone rubber. This material is resistant to damage caused by most chemicals and does not fracture or craze with time.
• Glass thread is woven into the resistance element, which gives it an extra layer of strength that protects it from cracking. Meanwhile, sheathing made of fiberglass-reinforced silicone rubber completely envelops it on all sides.
• Leadwires have a conventional diameter of ten inches and are insulated with Teflon; yet, different kinds may be used. The standards of either MIL-W-16878 or MIL-W-8777 are satisfied by standard leadwires. Leadwires can leave the heater via any edge or surface.

The Optimal Solution to Your Particular Requirements

The flexible heaters that Rama Corporation manufactures are resilient, flexible, and versatile in their design. They provide an equal dispersion of heat over surfaces that may be either uniform or uneven. Our heaters are developed for industrial equipment and devices that need low to moderate heating levels. Because of their low weight and narrow cross-section, they may be used in areas with restricted access that are difficult or impossible to modify for other heating elements.
