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.

Industrial heating applications are numerous and varied. Heating requirements can range from freeze protection to precise maintenance of process temperature in piping, equipment, or vessels. Two commonly employed heating sources are electric resistance heaters and plant steam. While each has certain advantages, steam may not always be available or practical. Electric heat offers a number of positive attributes.

  • Ease of design and installation
  • Precise control
  • Uniform heating across surfaces
  • Low maintenance requirement
  • Portability
  • Economical to purchase and install
  • Wide array of shapes, sizes, and configurations
  • Standard and custom products for every application
Cloth heating jackets are one of many electric heater variants. Formed to fit specific valves, fittings, or other items, these reusable heaters are comprised of an exterior of rugged fabric, a layer of thermal insulation, a heating blanket, and an electrical connection point or fitting. Hook and loop fasteners facilitate the unwrapping or opening of the jacket to allow for installation and removal. The surface remains cool to the touch for most applications. Control can be provided by any type of temperature controller, with prewired options available for inclusion with the heating jacket.

More detail is provided in the document included below. Share your process heating requirements with application specialists, combining your own process knowledge and experience with their product application expertise to develop effective solutions.
