Spotlight on: Spirax Sarco Removable Insulation Jackets

Exposed steam system components lose heat, waste energy, and create safety hazards for anyone working nearby. Traditional insulation solves part of that problem, but it's often a one-and-done installation; you cut it open for maintenance, and you're buying new insulation to replace what you tore off.

Spirax Sarco's removable, reusable insulation jackets are built to solve both problems at once: durable thermal protection that comes off cleanly for maintenance and goes right back on, no replacement required.

What aRE Spirax INSULATION JACKETS? 

Spirax Sarco Removeable Insulation Jackets are custom-fit covers engineered to provide superior insulation and minimized heat loss for specific components within a steam and condensate loop. These soft-shell covers are made of 1" thick, high-density fiberglass material with a chemical resistant coating and Velcro closure. They are designed to fit snugly around the shape of the item they're paired with. By reducing energy consumption and preventing condensation, Spirax Sarco insulation jackets enhance operational efficiency, reduce greenhouse gas emissions, and save costs in the long run. 

What Components Can You They Work With?

These insulation jackets, also known as Acoustic Blankets, aren't a generic industrial product adapted to fit steam equipment; they're purpose-built for it. Rather than a generic wrap, each jacket is shaped to conform tightly to the equipment it covers, eliminating the air gaps while also providing high heat retention and low external touch temperatures. Their unique designs are built to cover:

• Spirax Sarco Float & Thermostatic Traps and Inverted Bucket Traps - B Series Inverted Bucket Traps, UIB30 Series Inverted Bucket Traps, T15-125, FTI, FTB, FT14, FT450, UFT14HC, and UFT32 Traps
• Spirax Sarco Pressure Reducing Valves (PRVs) - 25 Series Pressure Reducing Valves, 26 Series Pressure Reducing Valves, and BRVs including the BRV2S Series Pressure Regulators
• Spirax Sarco Pressure-Powered Pumps - APT14 & APT14HC Series Automatic Pump Traps, APT10-4.5, PPEC, PTC, PTF, and PTF4 Pumps
• Spirax Sarco Control Valves - Spira-Trol LEA/KEA Valve Bodies
• Spirax Sarco Pipeline Connectors - STS17.2 Compact Pipeline Connector Steam Trapping Stations
• Spirax Sarco Manifolds - Steam Distribution and Condensation Collection
• Spirax Sarco Culinary/Clean Steam Filters - CSF16 Clean Steam FIlters
• Spirax Sarco Flash Vessels - 6"-16" Flash Recovery Vessels
• Spirax Sarco Separators - S1, S12, S13, S5, S6, and S4A Separators

what sets these jackets apart from the rest?

Value. These jackets are the smarter alternative to traditional single-use insulation because they deliver unmatched long-term value in multiple areas:

1. Durability- Spirax Sarco's jackets are engineered to hold up in demanding indoor and outdoor conditions over the long term, and the whole assembly is designed to be removed and refitted repeatedly without losing performance. The jackets are also rated for extreme heat, with a maximum product surface temperature of 464°F which is well within the range of demanding industrial steam applications. 
2. Safety - Exposed steam equipment can reach surface temperatures hot enough to cause serious burns. A steam trap operating at 240°F, for example, can be brought down to around 80°F once properly insulated by Spirax Sarco Jackets. This dramatically reduces the burn risk for personnel and contractors working nearby. The lower surface temperature also supports easier compliance with workplace safety regulations.
3. Energy Efficiency, Savings, and Sustainability - By minimizing heat loss at the component level, insulation jackets reduce condensate formation in the steam line. That means higher-quality steam reaches its point of use, which in turn reduces how much steam the system needs to generate in the first place. This lower energy consumption also supports broader decarbonization goals and reduces the ambient heat radiating off equipment into the surrounding facility.
4. Easier Maintenance - Since these jackets are designed to be taken off and refitted, technicians get fast access to the components underneath for inspection or repair without the need for cutting or replacing the insulation like other traditional alternatives require.

For facilities running steam and condensate systems, insulation is rarely the flashiest line item on a project list — but it has an outsized impact on safety, energy costs, and equipment longevity. Spirax Sarco's Insulation Jackets being removable and reusable jackets changes the economics of that decision: instead of choosing between good insulation and easy maintenance access, you get both. Fewer burns, lower energy bills, faster maintenance turnarounds, and a system that simply looks and runs better.

If your facility has steam traps, valves, or other components running exposed, it may be worth a closer look at where insulation jackets could make the biggest difference.
