Reciprocating engines—diesel, natural gas, and dual-fuel—are the workhorses of power generation, compression, marine propulsion, locomotive, and standby applications. They also produce concentrated, high-temperature exhaust that demands careful thermal management. Unitherm specializes in removable insulation systems built specifically for reciprocating engine service.
Reciprocating Engine Insulation Applications
- Exhaust manifolds (wet and dry)
- Turbochargers and turbo housings
- Exhaust downpipes, expansion joints, and silencers
- Aftertreatment systems—DPF, SCR, oxidation catalysts
- Cylinder heads on large-bore industrial and marine engines
- Lube oil coolers, jacket water systems, and aux piping
Unitherm’s Reciprocating Engine Insulation Solutions
Unitherm works with engine OEMs, packagers, EPC firms, and end users across every reciprocating engine application. Our removable covers are CAD-templated to specific engine models—Caterpillar, Cummins, Waukesha, MTU, Wartsila, EMD, and others—and built to survive vibration, oil exposure, and hundreds of removal cycles over the life of the engine.
Our reciprocating engine product line includes high-temperature exhaust insulation rated above 1,800°F, acoustic-attenuating covers for noise reduction, aftertreatment thermal management blankets, and weather-resistant assemblies for outdoor and offshore service. Quick-release fasteners make every cover easy to remove for oil changes, valve adjustments, and overhauls.
Key Benefits
- Lower surface temperatures to safe-touch levels
- Improve fuel efficiency by retaining exhaust energy
- Maintain aftertreatment temperatures for emissions compliance
- Reduce ambient heat in engine rooms and enclosures
- Cut maintenance time and extend insulation service life
