Silicone Rubber Heating Blankets


Electric heaters provide an effective and directed method in which heat can be delivered to a surface. The application of an electric heating solution is compartively simple and does not generally require a large amount of supoorting infrastructure, as is the case with fluid based heating systems. Electric heaters for industrial and commercial applications are available in a vast range of types, materials, and forms. The silicone rubber heater is one form that delivers users some unique application options.

A silicone rubber heating blanket is essentially a rugged but flexible rubber sheet with heating wire embedded within. Stock sizes are available, but the basic design enables manufacturers to craft custom sizes to meet very specific customer requirements. The distinct advantage of silicone rubber heating blankets is their flexibility. The resistance heater wires are encased in a silicone rubber sheet, providing the ability to wrap the assembly around an object or manipulate it into a close fit with the target of a heating application. The silicone rubber encasement also provides a high level of protection for the heater wires from impact, moisture, and some chemicals. The products are delivered with ready made connections or customized terminals to suit project needs.

The watt density of the heaters can be specified to provide a good match between the delivery of heat and the need for it. Electric heat can also be regulated by an external power controller to maintain very close temperature control. Custom shapes and configurations can be manufactured to order, and on board or remote controllers provided. Pressure sensitive adhesive is a common option that facilitates the installation of the heater assembly to a part or vessel.

The maximum application temperature is in the range of +450°F (+232°C). These heaters are a useful selection option for a large range of operations demanding heat to be applied directly to a surface, object, tank, drum, or other vessel. Share your industrial heating challenges with product specialists and leverage your own knowledge and experience with their product application expertise for the best match up between heater technology and your application.

Comprehensive Planning for Heat Trace and Surface Heating Challenges

Applications for process heating are numerous and varied,
found throughout industrial and commercial settings. 
Keeping process or inventory liquids from freezing, or becoming extremely viscous, can be an important part of a commercial or industrial operation. Freeze damage to equipment, piping, containers or their contents can result in a wide array of consequences, all of them likely to be negative.

Developing an overall plan for freeze protection can be advantageous to attacking each application on an independent basis.
  • Having a common vendor for all freeze protection equipment and supplies can help designers develop a knowledge base about how to meet application challenges with specific products, speeding implementation time. Service techs become familiar with applied products and methods, building their skills and efficiency at installing and maintaining applications throughout the facility.
  • Identify all locations where freeze protection is needed. Develop a baseline of the methods employed and equipment installed to meet the needs of each location. Good records form the basis for good maintenance and the ability to make decisions regarding the operation and performance of each system.
  • When selecting the products or methods to employ for freeze protection, consider the environment in which the hardware will be installed. Will it require protection from physical damage, chemical attack, or extreme weather. Is the installation space considered a hazardous zone, requiring special certifications for the heating equipment?
  • The availability and control of applied heat can also be important. Is there a need for the heating system to deliver highly variable amounts of heat across the range of possible operating scenarios, in order to avoid overheating the process or stored materials? How quickly will the system need to ramp up to the desired operating temperature or respond to changes in an operating process?
These questions, and probably others specifically related to your application, should be part of the consideration for freeze protection applications. Enlisting the cooperation of a process heat specialist can apply leverage to your own process knowledge and experience to develop an effective solution to each challenge.
