Industrial Heating Blankets

Industrial heating blankets deliver uniform, controlled heat for composite curing, rotor blade repair, ground thawing and process heating. Built with 7mm insulation and flexible heating elements, they conform to flat and curved surfaces — maintaining precise temperatures without hotspots or thermal damage to sensitive materials.

Used across wind energy, aerospace, marine and construction, HXP blankets are available in standard sizes from 600×600 mm to 3000×500 mm, with custom sizes and high-temperature variants for demanding applications.

What is an industrial heating blanket?

An industrial heating blanket is a flexible, insulated electric heater designed to apply even, controlled heat to a surface. Unlike bare heating elements or thin silicone pads, an industrial heating blanket incorporates insulation — typically 7mm — between the heating element and the outer surface. This insulation layer holds heat against the workpiece, prevents energy loss to the surroundings and ensures a uniform temperature field across the heated area. The result is a consistent cure or process temperature without hotspots that damage composite fibres, resins or other heat-sensitive materials.

Construction

HXP heating blankets are built around a resistance wire heating element encased in a flexible, durable outer shell with integrated insulation. They are designed to drape, wrap or lay flat against the surface being heated — conforming to flat panels, curved profiles and irregular geometry. Standard blankets operate up to 90°C. High-temperature variants handle elevated cure cycles for advanced prepreg systems. Both types connect to a digital temperature controller, allowing precise control of ramp rate, soak temperature and hold time.

Composite curing and rotor blade repair

The primary application for industrial heating blankets is the curing of epoxy and composite materials — carbon fibre, fibreglass and aramid — in situations where an autoclave is unavailable or impractical. In wind turbine rotor blade repair, a technician lays the blanket directly over the repair zone, applies vacuum bagging if required, and runs a controlled cure cycle. A blade can range from 40 to 100 metres in length: out-of-autoclave repair using portable heating blankets is the standard MRO method across the wind industry.

The same process applies in aerospace composite repair, marine manufacturing and automotive component production — wherever a fibre-reinforced plastic part must be cured, re-bonded or reworked without access to a fixed oven.

Ground thawing

The Ground Thawing Blanket operates at an automatic 70°C and thaws up to 30cm of frozen soil in 24 hours. Used in construction and civil engineering to prepare frozen ground for excavation, foundation work or utility installation in winter conditions. The robust outer construction handles direct placement on frozen surfaces outdoors.

Gas cylinder heating

The Gas Cylinder Heating Jacket wraps the full body of a gas cylinder in an insulated heater, improving vaporisation rate and maintaining consistent gas pressure during high-demand operation. Available in standard (up to 40°C) and high-temperature (up to 90°C) variants for different gas types and flow requirements.

High voltage cable straightening

The High Voltage Cable Straightening Jacket heats extra-high and high-voltage power cables to relieve mechanical stress before connection — enabling precise straightening and joining for cable diameters from 60 to 160 mm. Used by power cable installation contractors and grid maintenance teams.

Custom sizes and applications

Standard blankets cover sizes from 600×600 mm to 3000×500 mm for immediate delivery. When the repair zone, composite part or heated surface falls outside these dimensions, HXP manufactures custom blankets to any shape and size. Custom options include multi-zone temperature control, integrated thermocouples and application-specific temperature ratings.
