The HeatBooster HBL4 is a high-temperature industrial heat pump that recovers waste heat from water or steam at 10 to 150 °C and upgrades it to process heat, delivering hot water from 90 to 200 °C or steam up to 10 bar(a). It is driven by HEATEN's proprietary two-stage piston compressor, which keeps efficiency high at large temperature lifts and at partial load down to 20% of thermal output. One hardware platform works with both HFO and HC refrigerants, and units can be combined in parallel, cascade or two-stage configurations to scale up to 50+ MW th. The HBL4 is available in water/water, water/steam and steam/steam versions with a thermal power range of 0.8 to 2.5 MW th, and is in operation at HEATEN's Remscheid testbed in Germany.
