HYDRO DRY

Product catalog summary

Water Removal Efficiency
The Hydro-Dry filter elements are designed to remove up to 80% of free water present in oil using WR filter media. They work by absorption, ensuring high water retention capacity. For optimal efficiency, these elements should be used at a constant flow rate and low, constant pressure, ideally in an off-line filter or filtration trolley.

Solid Contamination Removal
While Hydro-Dry elements can remove solid contamination (ß21(c) > 1,000), it is recommended that the majority of solid contaminants be removed upstream by a dedicated return filter.

Standard Dimensions and Replacement
The elements are available in standard dimensions to fit standard filter housings. A clogging indicator set at 130 kPa (1.3 bar) is recommended for timely replacement of clogged elements.

System Care Recommendations
It is advised to fit RD series filter housings. The filter element used in ESF**NWR is made with the same filter media as other Hydro-Dry elements. The ERD series includes spin-on cartridges, while the ERF series fits OF series filter housings and the UOW filtration unit.

Technical Specifications
The document provides detailed specifications for various models, including H2O retention capacity and recommended maximum flow rates for different oil viscosities (98 cSt and 30 cSt). The specifications are subject to change without prior notice.

SYSTEM CARE WATER REMOVAL ELEMENTS The hydro-dry lter elements remove up to 80% of the free water present in the oil. The hydro-dry elements use the WR lter media, working by absorption and ensuring a high water retention capacity. To get the maximum water removal efciency the hydro-dry elements must be used at constant ow rate and low and constant pressure, i.e. the ideal use is in a off-line lter or in a ltration trolley. The hydro-dry elements remove also the solid contamination (ß21(c) > 1.000), but we recommend that the main part of solid contamination is removed upstream by a dedicated return lter. The hydro-dry elements are available in standard dimensions, to t standard lter housings. A clogging indicator set at 130 kPa (1,3 bar) on the lter housing is recommended for proper replacement of the clogged element.
