company profile
Shanghai Granklin (Group) Co., Ltd., located in the Robot Industrial Park in Baoshan District, Shanghai, spans an area of 60 acres. It is a high-tech enterprise that possesses independent intellectual property rights and specializes in the research, design, production, and sales of oil-free screw compressors.
Currently, our main products include seven series, namely, air-cooled and water-cooled ordinary water-lubricated oil-free screw compressors, medium-pressure oil-free screw compressors, low-pressure oil-free screw compressors, two-stage compression energy-saving oil-free screw compressors, integrated oil-free screw compressors, and special process gas compressors. Our products have obtained certifications such as ISO9001/ISO, ISO14001, German Class 0 oil-free certification, US FDA, EU CE, and medical device production qualification.
technology leads the future!
In various industrial production processes such as pharmaceuticals, electronics, chemical engineering, microbial fermentation, blow molding, pressure testing, and in power stations, compressed air ranging from 0.3 to 4.0 MPa is widely used. Currently, both domestically and internationally, there is an ongoing upgrade and replacement of screw air compressors. These compressors boast high overall operational efficiency, low noise levels, minimal vibration, convenient maintenance, low operating costs, and good air quality. Additionally, this series of machines incorporates a microcomputer control system, equipped with multiple protective features including pressure, temperature, and overload protection.
Technical advantages
Enhancing the meshing precision between the star wheel and the screw, overcoming the low viscosity characteristic of water, can maximize the approximation to isothermal compression, and ultimately pursue high compression efficiency; the water-lubricated single screw meshing profile adopts "suspended meshing" technology and is processed by a unique dedicated machine; the aerospace-grade stainless steel rotor perfectly matches with the hydrophilic PEEK star wheel.
Utilizing the patented mechanical seal technology from Granklin, we ensure that the compressed air is 100% oil-free. After extensive testing, the mechanical seal technology employed has demonstrated a lifespan exceeding 20,000 hours.
The main unit is made of special stainless steel, which exhibits strong corrosion resistance and wear resistance; the entire system is designed with all-stainless-steel components; the system comes with an intelligent water purification device.
Technical advantages
The company has been successively recognized as a "National High-tech Enterprise", and has won customer recognition with its powerful technology and excellent products. Its products are sold well all over the country, and it has actively explored the international market.
