Established in September 2005, KINFIT manufactures and markets an array of products, including combined air handling units, air handling units, constant-temperature and humidity air handling units, and rotary dehumidifying air conditioning units.
In recent years, KINFIT has proactively engaged in energy-saving renovation projects in line with the “Dual Carbon” policy. Sharing a common vision, ebm-papst and EC technology became their chosen partners. Consequently, when the semiconductor facility expressed their desire for retrofitting and upgrading their cooling towers, KINFIT immediately reached out to ebm-papst.

Maximum efficiency ensures energy savings
To tackle these issues, KINFIT and ebm-papst opted to replace the existing solution with 2 AxiBlade EC fans. The retrofit commenced on April 26, 2023, at 10:00 AM and was completed in approximately 7 hours. Following the system restart, the owner and KINFIT assessed the energy-saving performance of the EC fans based on temperature differentials between inlet and outlet water and power consumption before and after the upgrade.
The data revealed an impressive energy-saving rate of 51.25% in this project. When extrapolated for an annual operation of 6,912 hours (assuming continuous operation in the summer and an estimated annual usage of 80%), the result translates to annual electricity cost savings exceeding 16,000 RMB (about 2,000 Euro). Considering labor and material costs, the annual renovation benefits surpass 18,000 RMB (about 2,300 Euros).
More quality of life through environmental friendliness
This collaboration not only significantly reduced operational costs of the cooling towers through the energy-saving and maintenance-free design of the EC fans but also benefited from KINFIT’s customized control cabinet and meticulous attention to construction details, further enhancing the closed-loop control and efficient operation of the cooling towers.
As KINFIT emphasizes, the commitment to “ease the burden for customers” is shared by every member of their team. Their joint aim is to contribute to green building renovations and foster an improved quality of life, a commitment that unites both ebm-papst and KINFIT.
