Americans are paying more for electricity—and rates will keep rising.

The ROI of Waste Heat Recovery: Proven, Reliable, and Achievable in Three Years or Better

Across North America, industrial facilities lose enormous amounts of heat every day through hot, particulate-laden exhaust. ThermStar System™, powered by Lepido®, changes that by reclaiming waste heat, transferring it through a closed glycol loop or high-temperature fluid circuit, and reusing it as clean heating inside the facility.

Backed by proven global performance, ThermStar™ consistently delivers three-year or better ROI with measurable savings and long-term reliability.

Why ThermStar™ Is Different — And Why It Matters

Traditional heat recovery systems clog or fail in dirty exhaust environments. ThermStar™ uses patented Particle Repellant Geometry (PRG) technology which functions like an airplane wing, allowing most particles to pass through instead of accumulating on the coils. PRG means that the system continues reclaiming heat in real world conditions. Every installation since 2015 remains in operation today.

Key Benefits of ThermStar System™

  1. Significant energy-cost reduction, pay for energy once and use it twice. Turn waste into a renewable financial asset.

  2. Immediate Scope 1 carbon reductions through expending less energy in your processes or building heating.

  3. Reliable performance in particulate-heavy exhaust, resisting clogging and minimizing maintenance.

  4. Qualifies for many major incentive programs (Utility waste heat to energy programs, 179D depreciation, REAP, and more)

  5. Operational visibility through ThermStar Power Intelligence™, including dryer runtime, temperature delta, and pressure differential trends

Proven ROI: Real-World Results Across Industries

Across more than 200 global installations, ThermStar™, powered by Lepido®, has delivered reliable, verifiable savings in some of the harshest exhaust conditions.

Examples include:

  1. CWS Industrial Laundry: 63% natural gas savings, immediately realized and validated over a six-month pilot.

  2. Burger King (QSR): 36% energy reduction in grease-laden exhaust.

  3. Europe’s Largest Pancake Factory: Reused 99% of building heating needs.

  4. Bruzaholms Foundry: Significant energy savings and Scope 1 CO₂ reductions in a heavy-particulate environment.

  5. These outcomes are enabled by Lepido’s finless, staggered-coil PRG design, which maintains continuous heat recovery with a resistance to clogging that traditional heat exchangers cannot achieve.
