HYDAC Aquamicron® Water Removal Filter ElementsHOW WATER DAMAGESThe presence of water in hydraulic systems cause many problems. For example, the saturation of very fine filters or jamming of valves. These problems are often wrongly attributed to high levels of particle contamination. Added to this, the build-up of rust and the reduction in lubricating properties on bearings and slides can lead to considerable impairment in the effective functioning of a system. This goes to show that water, too, represents a serious "contaminant" in a hydraulic system. Previously, methods commonly used for extraction of water, have, on the whole, proven to be uneconomical in relation to the purchase price of a system. The HYDAC Aquamicron® technique offers an economically sound and yet an effective method of separating water from hydraulic media. DESCRIPTION Aquamicron® filter elements are specially designed to separate water from mineral oils. They are only supplied in the dimensions of HYDAC return line filter elements from size 330 and larger. This means that they can be installed in all HYDAC filter housings from size 330 which are fitted with return line filter elements. The increasing pressure loss in a filter element which is being saturated with water indicates, by means of standard clogging indicators, that it is time to change the element. When the Aquamicron® technique is employed, particle contaminants are also separated from the hydraulic medium as a by-product. This means that the Aquamicron® elements doubles as a safety filter. The "filtration rating" is 40 µm absolute (Β40≥ 100 to Δp = bar). In order to guarantee the greatest efficiency, it is recommended that these elements be installed in an off-line recirculation loop configuration. Principles of Aquamicron® Technology: The separation of water from mineral oils with the aid of the super absorber embedded in the filter mesh is based on a physical-chemical reaction. The super absorber in the element layer reacts with the water present in the hydraulic fluid and converts it to a gel. As it swells, the gel increases resistance to flow in the form of differential pressure increase across the element. This is a one way reaction and once the water is absorbed it cannot be released back in the fluid even by an increase in pressure. The Aquamicron® technique is capable of absorbing circulating water whether emulsified or free. These filter elements cannot remove dissolved water from the system, i.e. water below saturation level of the hydraulic fluid. |
