Process gases are an integral part of modern production. Compressed air, hydrogen, oxygen, argon, helium, carbon dioxide, nitrogen, SF6, natural gas, etc. are used in almost all indus­tries. For the effective use of gases in production processes, it is very important to control their humidity, high-quality preparation and drying. The development and creation of integrated solutions for humidity control, preparation and drying of process gases is one of the areas of specialization of JSC EKSIS, a Russian manufacturer of high-tech control and measuring instruments with more than twenty years of successful experience in the market. The proposed solutions are based on advanced developments: precision humidity meters IVG‑1, modern sample preparation systems and highly efficient gas drying units. Integration of this equipment into various technological processes allows solving a wide range of industrial problems. The article describes in detail the technical characteristics of the devices, their advantages and areas of application.
