Heat exchangers are critical components in a wide range of industries, working to efficiently transfer thermal energy from one medium to another. To reduce energy loss, improve safety, and enhance the performance of heat exchangers, it’s important to implement quality insulation jackets. At Firwin, we offer custom heat exchanger insulation jackets and covers constructed from durable materials for years of service. These removable covers are available in numerous shapes and sizes, and are designed to ensure a snug fit over your heat exchanger components. Heat exchanger insulation blanket

The Importance of Insulating Heat Exchangers

Thermal insulation jackets and covers are specifically designed to reduce heat loss, provide a safety barrier for extremely cold or hot applications, and improve the efficiency of heat exchangers. By acting as a thermal barrier, heat exchanger insulation jackets minimize heat transfer to the surrounding environment. The reduction of heat loss helps to maintain a higher temperature differential between the two fluids, improving the heat transfer process.

The lack of proper insulation for heat exchangers can result in numerous issues, including:

  • Reduction in product quality due to improper process temperatures
  • Equipment failure or breakdown
  • Frequent, unnecessary process adjustments
  • Incorrect readings

Unlike permanent insulation options, soft insulation covers are easy to remove and reuse, making them a great choice for heat exchanger components that require frequent maintenance and inspection. Other benefits of removable thermal insulation jackets include:

  • Freeze protection and heat retention
  • Temperature stability
  • Sound attenuation
  • Condensation prevention
  • Personnel protection against burns
  • Energy savings due to reduced heat loss

ThermoWrap Removable Insulation Covers

ThermoWrap Removable Insulation Covers

Firwin Corporation’s ThermoWrap insulation blankets, also known as insulation jackets or covers, are generally well-suited for lower-temperature applications, such as heat exchangers. They can be customized to precisely fit various heat exchanger components and are constructed from quality materials to ensure optimal performance. Although they are typically intended for applications under 500 °F, they can be made from alternative insulation materials to accommodate subzero temperatures all the way up to 2100 °F+.

ThermoWrap insulation covers feature high-temperature sewn construction and include closures, cutouts, and flaps for easy access to controls and ports. They can also come with various fastening methods, such as straps, cords, lacing wire, Velcro, and buckles.

Key specifications of our ThermoWrap insulation jackets include:

  • Custom Designed: Our engineers can design ThermoWrap removable insulation covers to fit any size or shape of heat exchanger.
  • Function: ThermoWrap blankets offer heat and energy conservation, heat retention, easy maintenance, personal protection, and sound attenuation. 
  • Temperature Limit: Subzero temperatures all the way to 2100 °F+
  • Insulation Thickness: Standard ranges span from ½ in. to 2 in.
  • Typical Lead Time: 2 to 3 weeks
  • Certifications: Firwin Corporation is fully ISO 9001:2015 certified, with UL certification also available for our most common materials.
