Products / Thermal Insulation Jackets

Removable Thermal Insulation Jackets

Removable insulation jackets custom-made for pipelines, heat exchangers, boiler doors, tanks and acoustic applications. Every jacket is measured for its specific equipment and sized with an ISO 12241 calculation.

Pipe Jackets

Removable Pipe Jacket

Flange, tee, elbow and reducer zones are hard to cover with conventional sheet-metal cladding; when maintenance is needed, the whole system has to be dismantled. OPTERM's removable pipe jackets are shaped for each specific geometry and come off easily during maintenance.

Custom geometry fit

A dedicated pattern is prepared for every point, including flange, tee and elbow zones.

Fast removal / refit

The maintenance team can reach the valve or pipe connection within 5 minutes by removing the jacket.

ISO 12241 calculated thickness

Insulation thickness calculated for service temperature and ambient conditions prevents unnecessary material use.

Heat Exchanger Jackets

Heat Exchanger & Equipment Insulation Jacket

When the bodies and covers of heat exchangers, pumps and process equipment are left uninsulated, they lose energy and face condensation risk. Removable insulation jackets based on equipment-specific geometry analysis allow every section that needs maintenance to be removed and refitted independently.

Section-by-section removable design

Body, cover and nozzle sections are designed as independent panels; removing one does not affect the others.

Condensation prevention

On cold lines it keeps the surface temperature above the dew point, eliminating condensation and corrosion risk.

Boiler Door Jackets

Boiler Door Insulation Jacket

When the front and rear doors of steam boilers and thermal oil boilers are insulated with fixed sheet cladding, any burner maintenance, gasket replacement, or periodic internal inspection means destroying the whole insulation and rebuilding it from scratch each time. OPTERM's boiler door jackets are custom-sewn to the door's full geometry, including the burner opening and inspection port; the jacket is removed before maintenance and refitted afterward.

Custom cutouts for burner and inspection port

Separate cutout allowances are left for every connection, gauge and inspection point on the door; installation never blocks access to any equipment.

Ready for periodic inspection

Before internal inspection, gasket replacement or burner overhaul, the jacket is removed within minutes, eliminating the need to cut and rebuild fixed cladding.

Tank & Reactor Jackets

Tank & Reactor Insulation Jacket

When large-diameter tanks and reactors are insulated with sheet-metal cladding, maintenance access becomes difficult. OPTERM's modular removable tank jackets are installed as panels, providing independent access to maintenance points.

Modular panel system

Each panel is installed and removed independently. Even on large tanks, fast installation is possible with a single person.

Long-life outer facing

Configured for the environment it is applied in, with aluminum foil, glass fabric or silicone facing options.

Acoustic Insulation Jackets

Acoustic Insulation Jacket

The noise generated by pressure-reducing valves, compressors and high-flow pipelines can exceed occupational safety limits and trigger environmental complaints. Combining sound and thermal insulation in a single product, acoustic jackets provide 15–25 dB(A) noise reduction.

Occupational safety compliance

Provides a solution for reducing the noise source in areas above 85 dB(A), lowering dependence on personal protective equipment.

Integrated with thermal insulation

The same jacket provides both sound and thermal insulation; one application and one maintenance point instead of two separate systems.

Frequently asked questions

Pipelines (including flange, tee, elbow and reducer zones, from DN15 to DN1200), heat exchanger and pump bodies, tanks and reactors, plus acoustic jackets for noise-generating equipment. Every jacket is measured for its specific equipment and sized with an ISO 12241 calculation.

The maintenance team reaches the connection point within 5 minutes by removing the jacket; there is no need to destroy the cladding as with fixed insulation. Since the body, cover and nozzle sections are designed as independent panels, removing one does not affect the others, and the same jacket is refitted after maintenance.

Depending on the product family, from −40°C to +900°C. On hot lines it reduces heat loss by up to 80%; on cold lines it keeps the surface temperature above the dew point, preventing condensation and corrosion risk.

It is calculated according to the ISO 12241 standard based on service temperature, ambient conditions and the targeted energy savings, and a calculation report is provided to the customer. This prevents unnecessary material use and reaches the target surface temperature by calculation.

Yes. Steam boiler and thermal oil boiler front/rear doors are custom-measured and sewn to the door's full geometry, including the burner opening and inspection port. The jacket is removed before maintenance and refitted afterward once the work is complete, without needing to destroy the insulation as with fixed sheet cladding.
