At standard atmospheric pressure, a dew point of −34°C corresponds to a moisture content of approximately 0.29 g/m³ (per dry air), or 156 ppmᵥ. This dew‑point level is suitable for high‑requirement industrial applications and is typically achieved using…

In most factories, electricity costs for compressed‑air systems account for20% ～ 35%of total energy consumption, yet the actual compression efficiency of conventional units often falls short of 70%—with substantial electrical energy wasted through unloading, leaks, and excess pressure.…

The high-altitude, low-oxygen, and wide-temperature‑range environment of Qinghai poses unique challenges to air compressors. Oil-free screw compressors, with their zero oil contamination, high purity, and robust environmental adaptability, have become the ideal choice for industries such as food,…

In industrial production, air compressors are often major contributors to electricity costs. Traditional fixed‑frequency compressors run at full speed regardless of changes in air demand; when demand drops, excess compressed air must be unloaded and vented, yet the…

The oil content in air separation cooling box directly affects the safety of oxygen system. According to GB/T 13277.1-2018 and ISO 8573-1:2010 standards, this paper defines the oil content limit (≤ 0.01 mg/m³) and its application requirements in…

This paper analyzes the essential differences between high-pressure water screw machine and high-pressure oil-free screw machine in lubrication principle, clean air implementation mode, applicable pressure range and operation and maintenance points, help users choose more suitable clean compressed…

The design of compressed air points in food factories is directly related to GMP compliance and product safety. This paper analyzes GMP index requirements of clean compressed air, and expounds the key design principles of Gas Point in…

This paper compares scroll compressor and screw compressor from four aspects: structural principle, energy efficiency performance, operating characteristics and typical applications, and points out that the former is superior in medium and small cooling capacity, high portion load…
