The owner of this company reached out to us in November last year, seeking our help to upgrade the old compressed air system.
Customer Challenges Before the Upgrade:
1. Air compressors: 1 unit of 75 kW + 2 units of 37 kW
①Equipment is outdated and frequently breaks down
②Annual electricity cost reaches RMB 455,000
2. Fixed-speed shell-and-tube refrigerated air dryer
①Noticeable moisture at air usage end, affecting product quality
②Pneumatic component failures and pipe corrosion
③High power consumption, poor energy efficiency
Our professional sales team visited the factory and carried out detailed site inspections and research to develop a tailored solution. After thoroughly communicating with the customer about the existing issues in the air station, we ultimately replaced their original equipment with a GGV40e air compressor.
Deman's Air System Comprises of:
1. Deman GGV40e energy-saving air compressor
①Customized air pressure and customized air flow
②Ultra energy-saving
③Ultra protection
④10-year warranty in China
2. 5DV PM VSD refrigerated air dryer
① Excellent water removal capability with stable PDP

This upgrade not only brought significant economic benefits to the customer by greatly reducing electricity costs, but also fundamentally solved the moisture issue at the air usage end, ensuring that production quality is no longer affected by water interference.
After Installation of Deman System:
√ The air compressor is 17.3% more energy-efficient than the old machine.
√ No more moisture in the workshop
√ Better product quality
√ Total annual energy savings：89,000 kWh
