High-Pressure Drying Unit BO 7/200 (UEC)

The BO 7/200 (UEC) drying unit, unlike other manufacturers' dryers, includes a water and oil separator, a cooler, final purification filters, and control and shut-off valves, and can operate continuously without stopping for regeneration. It allows for the production of "dry" air that is free from water, oil, and mechanical impurities, with a dew point of no more than -70 degrees Celsius, a pressure of up to 200 atm, and a volume of up to 7 m3/minute.
The main application of these dryers is in cryogenic systems for producing high-purity nitrogen and oxygen. It is also used in the aerospace industry, in the production of military equipment, and is suitable for breathing and is used by the Ministry of Emergency Situations to refill cylinders used for breathing during emergency situations and to refill cylinders used by divers.
