Waste Heat Recovery Heat Pump (WHRHP) units are advanced systems designed to capture low-grade waste heat from industrial or commercial processes and convert it into useful heating or hot water. Ideal for energy-intensive operations, these systems dramatically reduce energy consumption, improve process efficiency, and lower carbon emissions.

Waste Heat Recovery Heat Pump Units:

Rockshell Corp’s Industrial Heat Pumps capture waste energy from sources such as flue gas, exhaust air, process water, condenser heat from chillers, and cooling tower blowdown. These systems efficiently provide space heating, domestic hot water, preheating for boilers, and process heating. Designed with high-temperature lift capability, modular skid mounted construction, BMS/SCADA integration, energy monitoring, and configurable simultaneous heating and cooling, they reduce thermal waste and emissions, lower operational costs, and improve facility energy performance. Custom-engineered to your facility’s thermal profile, these solutions offer short payback periods and full lifecycle support—from design and commissioning to ongoing maintenance ensuring maximum efficiency and reliability.

Waste heat recovery from heat pumps for best COPs

Meet Sustainability Goals: They support decarbonization efforts and help meet scope 1 emission reduction targets. Reliable for Heavy-Duty Applications: Engineered for 24/7 industrial environments, the systems offer scalable capacities and high COPs (Coefficient of Performance). Transfer of heat from one location to another. They use a refrigeration cycle to extract heat from a low-temperature source and transfer it to a high-temperature sink. This process can be reversed to provide cooling when needed.

Waste heat can be recycled from the below processes.

  • Manufacturing Plants
  • Chemical & Pharmaceutical Production
  • Food & Beverage Processing
  • Heat rejection flues/stacks
  • Data Centres & Server Rooms
  • District Heating Systems
