Diesel generators are essential for reliable power generation across industrial, commercial, and emergency systems. However, their exhaust systems operate at extremely high temperatures — often exceeding 600°C (1112°F). Without proper insulation, this heat radiates into the surrounding area, increasing the risk of burns, damaging nearby components, and reducing energy efficiency.
A diesel generator exhaust insulation blanket provides an effective solution to these challenges. It minimizes surface temperature, enhances workplace safety, and improves system performance by keeping heat energy where it belongs — inside the exhaust.
A diesel generator exhaust insulation blanket is a removable, custom-made thermal cover designed to fit exhaust pipes, manifolds, turbochargers, and mufflers. These blankets are made from high-temperature insulation materials, such as fiberglass, silica, or ceramic fiber, and are enclosed in durable outer fabrics like silicone-coated fiberglass or stainless-steel mesh.
Each blanket is tailored to match the exact geometry of the generator exhaust, ensuring maximum coverage and easy removal for maintenance.
Typical Structure:
Inner Layer: Needled fiberglass or silica felt insulation (up to 1000°C)
Middle Layer: Reinforcement mesh for stability
Outer Layer: Heat-resistant silicone or PTFE-coated fiberglass fabric for durability
Fastening System: Stainless steel hooks, lacing wire, or Velcro straps for reusability
Uninsulated exhaust pipes can cause severe burns to operators and maintenance personnel. Installing exhaust insulation blankets lowers the external surface temperature by up to 90%, making the generator room significantly safer.
By retaining heat within the exhaust system, the insulation blanket improves thermal efficiency. Exhaust gases maintain higher temperatures, which can optimize turbocharger performance and reduce energy loss through radiation.
Thermal insulation prevents heat damage to sensitive components near the exhaust, including wiring, sensors, and control panels. This reduces downtime and extends the lifespan of generator components.
Exhaust blankets can also help reduce engine noise by dampening vibration and sound resonance, creating a quieter operating environment — particularly beneficial for power plants, hospitals, and residential standby systems.
BSTFLEX’s diesel generator exhaust insulation blankets are designed to be removable and reusable. They can be easily detached during regular maintenance and reinstalled without damage, minimizing operational downtime.

Each diesel generator exhaust insulation blanket is custom-made with labeled sections to simplify installation. Blankets wrap securely around exhaust parts and fasten using stainless steel wire or hooks.
To maintain optimal performance:
Inspect blankets every 6 months
Replace if outer fabric is damaged or oil-soaked
Ensure fastening systems are secure and properly tightened
Q1: Can the insulation blanket be used on both new and existing diesel generators?
Yes, BSTFLEX offers both OEM and retrofit solutions. We can design blankets based on CAD drawings, 3D scans, or direct measurement.
Q2: What temperature rating do I need for my generator?
Most diesel generator exhaust systems operate between 400°C and 700°C, so fiberglass or silica fiber blankets are sufficient. For higher temperatures, ceramic fiber blankets are recommended.
Q3: Are these blankets resistant to oil and moisture?
Yes. Our outer layers can be coated with silicone or PTFE for superior resistance to oil, water, and corrosion.
