Introduction
Overview
The HydrX™ Fuel Conditioning System is installed and used in diesel STP containment sumps. Its purpose is to
remove accumulated water from the tank bottom and help prevent microbial growth that can lead to broad fueling
system contamination and, ultimately, corrosion of fueling system components.
The HydrX system is controlled by a Fuel Conditioning Controller (FCC). The FCC operates in combination with a
TLS-450PLUS ATG using existing USM interfaces to Veeder-Root protocol digital devices as well as switched
pump control via IOM relays (see Figure
1).
Figure 1. HydrX Components
The HydrX system includes an in-sump Fuel Conditioner (FC) containing a water detection probe (single float) and
pressure sensor to monitor water collection and flow efficiency, respectively. In the process of removing water from
the fuel, the FCC utilizes 2-way inlet and outlet valves in the FC to control fuel flow through the Water Intake
Device (WID) for either suction-based extraction, pressure-based sweeping or fuel polishing.
