Revolutionizing industrial heat production

Guangzhou Nengyin Heat Pump Technology Co., Ltd.

Guangzhou Nengyin Heat Pump Technology Co., Ltd

Located in Guangdong Province, Guangzhou Nengyin Heat Pump Technology Co., Ltd. is a leader in high-temperature heat pump innovation. From its base in Foshan City, Nengyin is dedicated to developing efficient, high-performance heating technologies. Siemens has been a key partner for over a decade, committed to Nengyin's mission to revolutionize the high-temperature heat pump sector with groundbreaking solutions. Together, we are pushing the boundaries of industrial heating, setting new industry standards, and leading the way in sustainable solutions.

Challenges

In their quest to lead the high-temperature heat pump segment, Guangzhou Nengyin Heat Pump Technology Co., Ltd. faced some challenges. The primary pain point was the need for technological innovation that would ensure maximum efficiency and reliability in their heat pump applications, particularly in developing reliable solutions for high-temperature operation while optimizing system design for safety and efficiency.

Solution

In response to the challenges, Siemens embarked on a close collaboration with Guangzhou Nengyin Heat Pump Technology Co., Ltd., crafting a tailored solution to meet their specific needs. Instead of a one-size-fits-all approach, Siemens developed a bespoke total solution that includes the following components:

  • MVL702 magnetic expansion valve: higher operating temperature limit (Max. 130℃), accurate flow control, speed and valve accuracy to save energy by adapting superheat to lowest level yet stable operating point.
  • Climatix C400 controller: sharpens precision in system management.
  • Custom control application: tailored software that integrates seamlessly with existing technologies, honed to match Guangzhou Nengyin’s unique control logic and specific operational requirements.
  • Steam pressure and temperature sensors.

This customized approach not only meets but also exceeds the rigorous standards required, ensuring optimal performance and reliability.

How the solution helped solve customer’s challenges

In transformative pilot tests within Nengyin's state-of-the-art laboratory, the Siemens tailored solution marked a significant leap in performance.
