In Suihua, an old industrial base in Northeast China, four conventional Roots blowers once produced noise exceeding 85 decibels in the blower house of a medium-sized manufacturing enterprise, reflecting the heavy energy consumption of traditional industrial equipment. After four Kelupp oil-free screw blowers were put into operation smoothly, the equipment replacement initially aimed at noise reduction has become a typical solution to industrial problems of high energy consumption, loud noise and frequent maintenance. The energy efficiency level has been upgraded from GB Level 3 to Level 1. With all incremental investment recovered within 18 months, it has set a new economic benchmark for energy-saving renovation in industries in cold regions.

Along the Yangtze River stands a production base of Conch Cement, a global leader in the cement industry in Zongyang, Anhui. With roaring machinery and constant kiln flames, raw ores are turned into fundamental building materials every day. Behind this grand industrial scene lies an ongoing campaign to cut energy consumption. As a typical energy-intensive sector, cement production faces dual pressures of cost control and environmental protection across all processes. The blower systems, which support raw material homogenization, pulverized coal conveying at kiln inlet and outlet, and pneumatic transmission, run continuously in large quantities and have become the key to energy efficiency improvement. Zongyang Conch Cement launched an in-depth energy-saving upgrade to resolve power consumption challenges amid heavy dust and non-stop production conditions.
