Exhaust systems are among the highest-temperature components in any industrial or mobile application. Untreated exhaust pipes, manifolds, and turbo housings routinely radiate enough heat to damage adjacent equipment, injure personnel, accelerate corrosion, and waste fuel. Properly engineered insulation transforms exhaust systems from a liability into a controlled, efficient part of the machine.
Why Exhaust Insulation Is Essential
- Reduce surface temperatures from 1,200°F+ down to safe-touch levels
- Protect nearby wiring, hoses, and sensors from radiant heat
- Improve turbocharger response by keeping exhaust gases hot inside the manifold
- Lower engine-bay and cabin temperatures for personnel comfort
- Reduce noise and improve workplace acoustics
Unitherm’s Exhaust Insulation Solutions
Unitherm designs custom, removable exhaust insulation for engines and equipment across every major industry—reciprocating engines, turbines, locomotives, marine propulsion, gas compressors, and stationary power. Each cover is CAD-templated to fit the exact geometry of the manifold, turbo, downpipe, muffler, or stack, with quick-release fasteners that allow removal in minutes for inspection or repair.
Our exhaust product line includes high-temperature removable blankets rated above 1,800°F, hard-shell composite covers for high-abrasion environments, acoustic-insulated exhaust blankets, and weather-resistant outdoor assemblies for stationary equipment.
Key Benefits
- Personnel protection—eliminates burn hazards on hot exhaust surfaces
- Equipment protection—prevents heat damage to adjacent components
- Energy efficiency—keeps exhaust energy where it belongs (turbo, aftertreatment)
- Emissions compliance—maintains optimal SCR/DPF inlet temperatures
- Reusable design—removable for maintenance, no rework required
If you have a hot exhaust system, Unitherm can build a thermal solution that protects your people, your equipment, and your bottom line. Contact us with photos or drawings of your application to get started.
