IAG’s hydrant solution for all types of machinery represents an attractive alternative to conventional spindle-drive designs. Unlike such systems, the system is kept open by applying a 24 V power supply. To ensure proper functioning even at high intake pressures, a special electromagnetically opened solenoid valve is integrated, a device that has proven reliable in many years of use.

The compact unit, which may be screw-mounted directly on the line, additionally includes an overpressure regulator. This arrangement ensures that water is supplied to the machine at a constant pressure level, regardless of the geodetic pressure, and prevents any overpressure load to the machine. The system responds within a fraction of a second, in this way preventing any pressure peaks that might otherwise occur with slow-response spindle drives. The system closes immediately in the event of any power fallout, so that there is no risk of water damage to ski slopes.

The safety valve in the feed line prevents any damage to the line. This provides the additional advantage of optionally shutting down equipment immediately. Unlike spindle-drive hydrants, which may require minutes before the machine can be shut down, the IAG hydrant cuts operation immediately.

The system is easily mounted. Like conventional hydrants, it can be screw-mounted directly on existing water supply lines.
