RHP2000 High Inlet Temperature Refrigerated Air Dryer

Water droplets are formed by the condensed water vapor present in ambient air. Solid particles come from ambient air contaminants like dust and from rusted, oxidized pipework. They can obstruct orifices used in laboratory testing procedures and cause pneumatic equipment to malfunction.

Liquid oil and oil vapors are introduced by compressor coolants and by hydrocarbon vapors present in ambient air. Oil-free compressed air is particularly important in food and pharmaceutical processes where direct and indirect contact with compressed air occurs. Pharmaceutical testing and packaging is a common application for compressed air at 700–900 psig (39–63 bar) working pressure.
