HYDRO-DRY

Water removal elements

FEATURES

The hydro-dry filter elements remove up to 80% of the free water present in the oil.

The hydro-dry elements use the FormulaUFI.H2O filter media, working by absorption and ensuring a high water retention capacity.

To get the maximum water removal efficiency the hydro-dry elements must be used at constant flow rate and low and constant pressure, i.e. the ideal use is in off-line filters or in filtration units.

The hydro-dry elements remove also the solid contamination (ß21(c) > 1.000), but we recommend to remove the main part of solid contamination using a dedicated return line filter.

The hydro-dry elements are available in standard dimensions, to fit standard filter housings.

A clogging indicator set at 130 kPa (1,3 bar) on the filter housing is recommended for proper replacement of the clogged element.

UOW022

Portable filling and filtration unit

FEATURES

Inlet: flexible hose Steelflex 16HNA, 2,5 m long with rigid end DE16 0,4 m long
Outlet: flexible hose Steelflexx 13HNA, 2,5 m long with rigid end DE12 0,4 m long
“Y” type filter for pump protection
Gear pump 22 l/min, 2800 rpm
Electric motor single phase 230V - 0,25 kW – 2 poles - B3/B5
Double handle for easy and safe transportation
Total weight 16,5 kg

HOW IT WORKS

The mobile filtration unit is used for cleaning the fluid off line, for the transfer, filling and topping up of the oil tank and for any roll-off operation. The oil returning to the tank-reservoir from the return line is filtered by the UOW unit, reducing drastically the “clean-up time.” The filter can be fitted with a visual clogging indicator, also of differential type

UOW040

Portable filling and filtration unit with green element

FEATURES

Inlet and Outlet flexible hose, 2 m long with rigid end 0,5 m long

Gear pump 40 l/min with inbuilt 1 MPa (10 bar) relief valve

Electric motor: three phase 380V - 0,75 kW 1450 rpm - IP54

Double handle for proper and easy transportation

WEIGHT
50 Kg

HOW IT WORKS

The mobile filtration unit is used for cleaning the fluid off line, for the transfer, filling and topping up of the oil tank and for any roll-off operation.

The UOW mobile off-line filtration unit filters hydraulic fluid at low-pressure with the aid of a self-contained pump, motor and filter.

The construction design is compact and user-friendly, and guarantees high filtration performances and long life filter element.
