Soloheat jackets differences

Soloheat manufactures bespoke high-temperature insulation jackets for industrial heating and process applications. Jackets can be manufactured to fit around externally mounted industrial heating elements, heated barrels, dies, pipework, valves, flanges and other process equipment.

Our insulation jackets are available in constructions up to approximately 38 mm thick, with fastening options including VELCRO® or cam buckles depending on the operating temperature and application.

Depending on the materials and construction selected, insulation jackets can be manufactured for operating temperatures of up to approximately 500°C. High-temperature, flame-resistant or non-combustible materials are selected where appropriate for the application. We use Kevlar-coated stainless-steel thread for all stitching, providing a durable and robust jacket construction.

Why Consider Using Soloheat Insulation Jackets?

  1. Reduced heat loss and energy consumption – insulating exposed heated surfaces can significantly reduce heat loss to the surrounding environment. Potential energy savings and payback period depend on operating temperature, equipment design, operating hours and process duty.
  2. Reduced exposed surface temperatures – correctly specified insulation jackets can substantially reduce accessible surface temperatures and may help reduce burn risk as part of a suitable workplace risk-control strategy.
  3. Heater protection – suitable jacket constructions can help protect externally mounted heaters from contamination such as molten polymer or plastic drool, potentially reducing damage and extending heater service life.
  4. Improved process stability – reducing uncontrolled heat loss can help provide more consistent process temperatures and reduce unnecessary heater cycling.

Additional benefits can include:

  • More consistent barrel and process temperatures
  • Reduced heater cycling
  • Faster warm-up
  • Reduced heat loss to the surrounding working environment
  • Protection from process contamination
  • Potential reduction in energy consumption

How Insulation Jackets work

Soloheat’s custom high-temperature insulation jackets are manufactured to fit the non-contact surfaces of a wide range of industrial heating elements, machinery and process equipment, including complex and irregular shapes.

They can also be fitted around internally heated tooling and machine components, including equipment heated by cartridge heaters. By insulating exposed heated surfaces, the jackets help reduce heat loss to the surrounding environment, improve thermal efficiency and reduce energy consumption.

Insulation Jacket FAQ's

How much energy can insulation jackets save?

The energy savings achieved by insulation jackets depend on factors including operating temperature, exposed surface area, equipment design, ambient conditions and operating hours. By reducing radiant and convective heat losses, less energy may be required to maintain the required process temperature. In suitable continuously heated applications, this can result in significant reductions in energy consumption and operating costs.

Can insulation jackets be removed?

Yes. Soloheat insulation jackets are designed to be removable and reusable. Hook-and-loop fasteners, straps, cam buckles or other suitable fixing methods allow jackets to be removed for maintenance, inspection or replacement of heating elements and then refitted.

How hot can insulation jackets operate at?

Our high-temperature insulation jackets can be manufactured for continuous operating temperatures of up to approximately 500°C, depending on the materials, construction and application. Material selection is matched to the intended operating conditions.

Are insulation jackets waterproof?

Jackets manufactured with suitable coated outer fabrics can provide good resistance to moisture, oils and industrial contaminants. However, standard insulation jackets should not be considered waterproof or suitable for permanent immersion, high-pressure wash-down or other severe wet environments unless specifically designed for those conditions.

Can cut-outs be added?

Yes. Every insulation jacket is custom manufactured and can incorporate cut-outs or openings for terminal boxes, thermocouples, sensors, pipework, brackets, lifting points, mounting bolts and other equipment. The jacket can be designed around these features while maintaining practical installation and removal.

What materials are used?

Soloheat insulation jackets are manufactured using materials selected to suit the operating temperature and environment. Depending on the application, these can include coated glass-fibre outer fabrics, glass-fibre or specialist high-temperature insulation materials, together with robust fastening systems. Kevlar-coated stainless-steel thread is used for all stitching.

Can insulation jackets fit existing heaters?

Yes. Our insulation jackets are custom manufactured for both new and existing industrial heating equipment. Applications include band heaters, ceramic heaters, cast heaters, barrel heaters, pipework, valves, vessels, tooling and many other heated components, whether or not the original equipment was supplied by Soloheat.

Can insulation jackets help improve heater life?

In suitable applications, insulation jackets can reduce heat loss and unnecessary heater cycling. They can also provide physical protection against some forms of process contamination. These factors may help reduce thermal and environmental stresses on externally mounted heating elements, although heater service life will also depend on heater design, watt density, process temperature, control and operating conditions.

What measurements are required?

The measurements required depend on the application. Typically, we require overall dimensions, diameter or circumference, height or length, together with the positions of terminal boxes, sensors, supports and other obstructions. Photographs, drawings or simple sketches are also useful, and our team can advise if additional dimensions are required.

How long do insulation jackets last?

Service life depends on operating temperature, handling, contamination, installation and environmental conditions. A correctly specified jacket manufactured from suitable materials can provide extended service in industrial applications, while removable construction allows inspection and maintenance as required.
