High-Horsepower Thermal Protection for Cummins QSK Engines

The Cummins QSK60 (16-cylinder, 60-liter, up to 3,000 hp / 2,200 ekW) and QSK50 (16-cylinder, 50-liter, up to 2,500 hp / 1,800 ekW) are powerhorses engineered for demanding continuous, prime, and standby operations. These massive reciprocating engines generate significant exhaust thermal loads that require specialized Cummins exhaust insulation and protective shielding:

• Extreme Exhaust Temperatures: Exhaust gas exiting cylinder ports operates continuously between 900°F and 1,150°F (482°C to 621°C). Unshielded dry manifolds radiate extreme heat into enclosed generator housings.
• Enclosure & Control Module Protection: High radiant heat degrades sensitive Cummins Quantum System ECM controllers, wiring harnesses, oil pressure sensors, and alternator windings. Deploying proven Cummins genset insulation and Cummins generator exhaust insulation reduces internal canopy ambient temperatures by up to 70°F.
• OSHA Personnel Burn Compliance: Bare manifold surfaces and turbine housings present dangerous burn risks for maintenance crews. ATC blankets guarantee outer touch temperatures below 140°F (60°C) per OSHA 1910.147.
• Hydrocarbon Fire Safety & SOLAS Standards: High-pressure common rail fuel lines and pressurized lube oil lines run adjacent to hot exhaust runners. ATC’s liquid-impermeable silicone and PTFE outer jacketing prevents atomized hydrocarbon mist absorption, eliminating combustion fire hazards and meeting SOLAS marine safety criteria.

Cummins QSK60 & QSK50 Component Blanket Kit Breakdown

Advanced Thermal Corp. manufactures complete, component-mapped Cummins engine insulation blankets designed for rapid field removal and precise reassembly. Each blanket is CAD-cut and stamped with identification tags corresponding to engine layout:

Cummins Component	Kit Architecture & Coverage	Engineering & Maintenance Benefit
Cummins Exhaust Manifold Insulation	Multi-piece segmented wraps providing precision Cummins exhaust manifold insulation for individual cylinder exhaust ports, log sections, and intermediate flanges on QSK60 and QSK50 blocks.	Allows technicians to remove only the blanket sections covering specific cylinders during valve lash adjustments or injector servicing without removing the entire manifold system.
Cummins Turbocharger Insulation Blanket	Custom two-piece split-shell covers offering dedicated Cummins turbo insulation and Cummins turbocharger insulation blanket systems for dual and quad Holset® turbine housings and wastegates.	Preserves exhaust gas thermal enthalpy to maintain optimal turbocharger spooling and transient load response while eliminating radiant heat into the generator room.
Cummins Exhaust Blankets & Flex Bellows	Flexible expansion joint covers engineered to insulate multi-ply stainless steel bellows connecting exhaust manifolds to discharge ducting.	Absorbs intense reciprocating engine vibration and axial thermal growth without tearing seams or degrading insulation density.
Exhaust Crossovers & Y-Collector Wraps	Full-wrap insulation covers for intermediate exhaust crossover tubes, balance lines, and merge collectors leading to the silencer.	Eliminates radiant hot spots and protects overhead intake air ducting and ventilation louvers from overheating.
Tier 4 Final SCR & Catalyst Blankets	High-efficiency thermal wraps for Selective Catalytic Reduction (SCR) reactors and exhaust aftertreatment canisters.	Maintains required catalyst light-off operating temperatures for NOx compliance while providing a safe touch-temperature exterior.

Maintenance & Operational Advantages of ATC Removable Blankets

Unlike rigid metal heat shields that rattle loose, crack, or make engine servicing difficult, ATC removable blankets offer significant operational benefits:

• Tool-Free Rapid Servicing: Heavy-duty quick-release spring latches allow maintenance crews to strip manifold blankets in minutes for routine valve lash checks, fuel injector service, or turbo overhauls, and reinstall them immediately without specialized tools.
• Engineered Reusability: Designed for 50+ removal and reinstallation cycles without loss of thermal performance or structural degradation.
• Integrated Sensor Ports: Factory cutouts with reinforced, heat-sealed edges accommodate pyrometer probes, thermocouple wires, and pressure sensor taps, ensuring full diagnostic capability during engine dyno testing and live operation.
• Vibration and Fatigue Resistance: Reciprocating engines produce intense cyclic vibration. ATC’s flexible, quilted construction absorbs mechanical stress without crumbling or generating airborne fiber dust.
