Beibingyang Unveils 140 °C Centrifugal Steam Heat Pump for Industrial Heating

Beibingyang Technology has released a high-temperature centrifugal steam heat pump engineered to deliver stable 140 °C hot-water output, addressing core heating demands in energy-intensive industrial sectors.

Core compressor and drive architecture

The unit is built around a patented high-pressure-ratio centrifugal compressor with a design pressure ratio of up to 17.0, producing a temperature rise of 111 °C and a pressure resistance of 3.5 MPa to ensure stable operation under high-temperature, high-pressure conditions. A dedicated centrifugal compressor for water-vapor compression is coupled to a permanent-magnet synchronous motor with high-speed variable-frequency direct drive, achieving a saturated temperature rise of up to 40 °C.

Application scenarios and target industries

The equipment covers two principal heating scenarios:

• Direct supply of 140 °C high-temperature hot water.
• Conversion of that hot water into 120 °C–130 °C saturated low-pressure steam, with output parameters approaching 140 °C to cover the majority of conventional production-line steam requirements.

For special conditions requiring saturated steam at around 180 °C, a combination of steam re-compression technology and a steam compressor can be applied to meet the demand. The unit is suited to core heating needs in the textile, food-processing, fermentation, and conventional chemical industries.

Zhao Shufu, Deputy General Manager and R&D Director at Beibingyang Technology, noted that mainstream heat-pump refrigerants have critical temperature limits of 150 °C to 160 °C, and that achieving stable 140 °C hot-water output under this physical constraint represents an industry-leading technology level, marking a key step in independent innovation in China's high-temperature heat-pump sector.
