Convert residual waste heat to 100–200°C process heat with Upheat’s oil‑free heat pumps — 3–6 COP, natural refrigerants, low maintenance, fossil-fuel replacement.

Recovering residual waste heat is a low-hanging fruit for industrial decarbonization — yet much of it is still vented because conventional systems can’t raise temperatures high enough for process use. Traditional heat pumps can typically provide heat at around 80–90°C, which is often not that useful, apart from heating the building. The temperatures required by the production processes are too high for the traditional heat pumps. Upheat changes the economics and the physics: our oil‑free high‑temperature heat pumps are optimized to deliver reliable process heat between 100°C and 200°C, enabling businesses to replace natural gas and cut CO₂ emissions with the energy that is already existing and paid for.

Why residual waste heat is often wasted

  • Insufficient temperature: Direct heat-recovery provides only lower temperatures, leaving the heat unsuitable for industrial process needs.
  • Poor return on investment: If recovered heat can’t be used to replace high-CO2 and high-cost heat, systems are hard to justify economically.
  • Maintenance and contamination concerns: Oil-lubricated compressors and complex drive trains increase service needs and risk refrigerant contamination, which reduces long-term efficiency and reliability.

What makes Upheat different

Upheat is designed specifically for demanding industrial environments where higher temperature process heat is needed:

  • Optimized for heat sink temperatures between 100°C and 200°C.
  • Capable of temperature lifts between 40°C and 110°C — turning low-grade waste heat into process-ready thermal energy as pressurized hot water or steam.
  • Oil-free architecture allows operation across the 100–200°C range with practically no maintenance costs and high reliability and scalability.

Technical advantages that matter

  • Oil-free high-speed turbo compressors: Eliminating oil in compressor bearings, no gears reduces contamination risk and simplifies the system. The compressor uses a high-speed motor and direct-drive turbo compression for compact, efficient operation.
  • Active Magnetic Bearings (AMB): The rotor levitates on AMBs, so the only medium in contact with the rotor is the refrigerant. This removes mechanical friction, significantly reduces wear, and lowers maintenance requirements.
  • Clean heat-exchanger surfaces: Without oil circulating in the system, heat-exchanger surfaces stay clean longer, enhancing thermal efficiency and reducing downtime.
  • Natural refrigerants and compliance-ready design: Upheat utilizes environmentally friendly refrigerants and is designed with FGAS and PFAS regulatory future in mind, future-proofing installations for decades.
  • Flexible operating range: The technology maintains high efficiency across varied operating points to match changing production loads and process demands.
  • As a ready-made, productized, and factory-tested solution, it makes the implementation projects easy and very cost-effective.

Performance and environmental impact

  • High coefficient of performance (COP): Upheat heat pumps can deliver 3 to 6 times more heat energy than the electrical energy consumed, offering strong operational economics.
  • Carbon emissions reduction: By enabling process heat above 100°C without burning fossil fuels, Upheat helps facilities substantially reduce scope 1 emissions and reliance on natural gas. The energy is already there – just needs to be reused.
  • Lower lifecycle costs: Reduced maintenance, fewer consumables (no oil), high efficiency and easy integration translate into lower total cost of ownership and faster payback periods compared with fossil-fuel solutions.
