Cut energy waste. Save money.
Every bit of heat lost from your steam system is energy—and money—gone. Our insulation jackets are built to keep that heat where it belongs. That means lower fuel bills, reduced carbon emissions, and a more sustainable operation.
Energy savings translate directly to carbon reduction – each kilowatt-hour of thermal energy wasted generates approximately 0.18 kilograms of CO₂ equivalent when you're raising steam from natural gas."The Department for Energy Security and Net Zero
Keep your team safe
Hot surfaces are a hazard. Our jackets act as a protective layer, reducing the risk of burns and helping you meet safety standards. They’re a simple way to show your people you care.
Built for your equipment. Built to last.
These aren’t generic covers. Each Spirax Sarco insulation jacket is tailor-made to fit our components precisely. That means better insulation, longer life, and fewer maintenance headaches. They’re tough and designed to handle high temperatures, harsh conditions, and daily wear.
Easy to install. Easy to live with.
We know downtime costs you. That’s why our jackets are designed for quick installation and straightforward maintenance. Clear labelling makes inspections faster, and durable fastenings mean they stay in place, even in demanding environments.
Designed for your industry
Whether you're in food and beverage, pharma, healthcare, or heavy industry, we’ve got you covered. Our jackets are available for a wide range of Spirax Sarco components—from pressure reducing valves to steam traps and condensate recovery units.
Avoid burns and energy losses with reusable insulation jackets
Burns are one of the most common workplace injuries for people who come into contact with steam systems. With Spirax Sarco's handy reusable insulation jackets, you effectively reduce the risks in your work environment and at the same time significantly save energy.
Identify energy thieves - isolate your valves
A hot valve is an occupational safety risk, and a hot uninsulated valve also wastes large amounts of energy. However, both problems can be solved with Spirax Sarco insulation jackets.
The easiest way to significantly save energy
Did you know that the heat loss of an uninsulated valve can correspond to the annual energy consumption of an average household. Spirax Sarco can help you calculate the payback period and insulate the valves with reusable, easy-to-install isolation jackets.
