Product is the Statement of Who We are
Safe
Since 2017, we have proudly offered a ten-year warranty policy on our compressors in China. We deeply understand that even a single production halt due to compressor failure could lead to significant losses. That’s why our engineering and production process are guided by the “ten-year failure-free” standard, assuring each air compressor is designed and built to the highest standards of durability and reliability.
Energy-saving
We are the forerunner of energy-saving technologies in the industry. We launched our first VSD oil-injected air compressor in 2004 and drafted China’s industry standard for VSD Oil-injected and PM VSD Screw Air Compressors. In 2015, we launched two-stage PM VSD air compressors. Our products have won the "Energy Efficiency Star" awarded by the Ministry of Industry and Information Technology (MIIT) for five consecutive years. In 2024, we were honored as "Compressed Air System Energy Saving Outstanding Contributor" by the China General Machinery Industry Association (CGMA), the only Chinese air compressor manufacturer awarded along with multinational corporates.
Smart
Each Deman air compressor is equipped with “Deman Cloud” intelligent remote monitoring and control system to continuously monitor and ensure the safe running of each installed machine. Additionally, Deman self-developed “Air Commander” multi-compressor central control system is able to optimize the energy efficiency of the entire installation by automatically calculating and adjusting the optimal load for each air compressor.
Customized Air Pressure
Deman’s self-developed intelligent variable frequency constant pressure control system can accurately control the output air pressure according to the customer’s production requirement. The system is able to maintain the output air pressure within the range of ±0.002MPa, which effectively reduces the energy consumption of the whole compressor. Deman holds the Invention patent of "Intelligent Variable Frequency Screw Air Compressor Control System".
Customized Air Flow
Deman intelligent variable frequency control system can intelligently output the optimal air flow according to customer’s minimal pressure requirement. In addition, we also offer customized air compressor tailored to specific air flow and air pressure requirement, to ensure optimal operating efficiency under the specified working requirement.
Customized Air Quality
For selected popular compressor models, Deman provides integrated air compressors with after-treatment configurations to meet the air quality requirement of different industries. In addition, our professional sales engineers can provide the tailored after-treatment solution for the compressed air station, to not only meet the air quality requirement, but also low pressure drop and high energy efficiency.
