HYDRO/P1A is a device for the recovery of LNAPL, equipped with elements dedicated to the recognition of air/water/product and stop and automatic restart systems. The device works with AC 220V electrical control panel that controls the pick-up equipment, which operates in DC 12V. The equipment is provided with a maximum delivery height of 5 bars (reference data: flow rate of 2,0 l/min with 1 bars delivery height). The control panel is normally made in IP55 version for outdoor installation; if required, it can be made in an explosion-proof Exd version. The components of the recognition system of air/water/product (floaters) form an intrinsically safe circuit Exia (double level floater Exia, driven by an isolated dual channel barrier Exia) with a protection up to two independent failures in the system. The device has a maximum delivery height of 55 metres and it is provided as standard with a 20 metres cable that is equipped with two interchangeable metal mesh filters.
