Gear-driven Centrifugal Air Compressor Ensures Stable Operation and Saves Over 1 Million RMB on Electricity Annually for

A glass manufacturing plant formerly equipped with four imported screw compressors. The units frequently tripped in high temperature, accompanied by insufficient air volume, which caused air bubbles and uneven thickness on finished glass products with a rejection rate of 5%.

The factory replaced the old equipment with two gear-driven centrifugal air compressors and built an integrated intelligent air compressor station. Featuring low-speed large rotors and premium bearings, the units adopt forced heat dissipation structure and perform well under high temperature conditions.

After renovation, the total air supply capacity is doubled, and no tripping fault occurs in hot weather. The product rejection rate is reduced to zero. The overall energy saving rate reaches 40%, saving more than 1 million RMB on electricity fees every year. With a designed service life of 15 years, the equipment operates stably with no major overhaul required in long-term service.
