This adsorber is available with and without an inlet valve. In the valve-free version, the sucked-in air flows into the adsorber almost without pressure and is distributed evenly over the cross-section. The valve version has a somewhat higher differential pressure and is used in combination with a venting system.
When the desiccant silica gel flows through, the water molecules are safely removed from the air. The gap volume of the granules is optimally selected with 2 to 5mm grains and guarantees a minimum pressure build-up with simultaneous very good drying efficiency. Thus, at the beginning of the drying process, a residual air humidity of max. 2 % rH and a dew point of -40 °C are achieved. Due to the water absorption, the silica gel in the standard changes color from orange to green. A complete green coloration indicates the end of the product life cycle.
MS-R adsorbers consist of a stainless steel A4 housing, silica gel orange and FKM seals. They are used for aeration of oils and lubricants, fuels, isocyanates, chemicals and solvents in large storage tanks.
