Deterioration of the quality of process conditions, products and services due to bad compressed air is the main cause of damage to pneumatic components, instruments and other equipment. Statistics show that the breakdown of 85% or more compressors is caused by unclean air. The pollutant of compressed air consists of water, which accounts for 80%, and its mixture of oil mist and solid particles. So, the main measure of purification is to get rid of water through drying. In the modern industrial system, a great number of products and services are provided by numerous small manufacturers and service providers. High-quality compressed air is required for equipment and process in many industries. The average air quantity required for a single point in many cases is about 0.2~0.4 m3/min, but the requirement is usually not satisfied due to lack of suitable equipment, and simple purifying process is used instead. Our company is devoted to providing equipment and technologies of compressed air drying and purification for users of small-flow compressed air and for independent compressed air equipment. We provide users with solutions of low-cost compressed air purification for equipment of small size, which would enhance the air processing quality and would be widely accepted as well. The series of products we provide include mini refrigeration dryers, adsorption dryers, and pure dry air compressors that combine these drying devices with oil-free air compressors. These compressors can be used for dental therapy, instruments and meters, and laboratories. Besides, we provide solutions for any special requirement, such as refrigeration dryers designed for hydrogen and carbon dioxide. It is our hope that these products can do something for enhancing the quality and value of our users&＃039; products and services. .
