Both the new Hya-Solo D FL single-pump unit and the Hya-Duo D FL dual-pump unit meet the criteria of the new DIN 14462 standard for fire-fighting water systems, which is valid since April 2009. The units have been designed for use in residential buildings as well as on commercial and industrial premises.
Their maximum flow rate is 110 m3 per hour, to a head of up to 160 m. The Hya-Duo D FL dual-pump unit features a stand-by pump and separate electric circuits.
The units are started up and switched off as a function of pressure and can be controlled via one or several remote ON-OFF limit switches at a wall hydrant. An optional flow-rate based control function makes it particularly easy to install the ready-to-plug-in package unit.
