Combat In-Tank Corrosion
The Veeder-Root HydrX Fuel Conditioning System combats in-tank corrosion by providing continuous water removal within diesel storage tanks. The unique design of HydrX removes water from the lowest point in the tank, preventing water from stagnating on the tank bottom and breeding microbial contaminants. The integrated filtration removes entrained water, rust, sand, and microbial particulate from the fuel, polishing it before returning clean fuel back to the tank.
Keep your fuel within specification and maintain equipment at peak efficiency to avoid unplanned site shutdowns.
Improve Fuel Quality and Maintain Optimal Flow Rate at the Dispenser
Micro-biologically Influenced Corrosion, caused by growing microbes in water, has been a persistent issue that causes fuel degradation and premature equipment breakdown. Water contamination is the chief enemy of diesel storage. Stagnant water on tank bottoms is the breeding ground for microbial activity, which leads to the production of corrosive acids and microbial waste. Continuous water removal is the only long-term, sustainable solution for optimal tank health and diesel fuel quality.
How it Works
- The Water Intake Device (WID) is inserted through a spare bung in the Submersible Turbine Pump (STP) sump, which rests on the tank bottom to access water from the lowest point in the tank.
- The WID is a multi-mode device powered by the STP to collect water from the bottom of the tank and entrained in the fuel, delivering it to the Fuel Conditioner in the sump. Fuel and water are separated through filtering, and the water kept in the containment vessel.
- Vacuum mode uses suction from the STP port to pull fuel, water, and particulate into the fuel conditioning system.
- Sweep mode uses clean fuel to push water and particulate to the lowest point in the tank, where it can be picked up by the WID.
- Polishing mode is activated when the vacuum and sweep modes are complete (i.e., no more water is being collected). This mode provides a fine polish for optimal fuel quality.
- Separation and filtration purifies the fuel before returning it to the tank.
- The TLS-450PLUS and TLS4 Automatic Tank Gauges (ATGs) allow the user to see the status of HydrX onsite or remotely, including the water level in real-time and alerts when the water containment vessel is full.
- When the water containment vessel is full, the system will automatically shutdown until the water is removed from the containment vessel.
- To remove the water, a site technician would quick-connect to the water containment vessel and drain water into a separate container for disposal.
