Petro Barrier is a system specially designed to easily adapt to any retention tank or pit, and retention volume. It ensures rainwater drainage by filtrating hydrocarbons traces, pumping the fluid through a filtration cartridge, while retaining all hydrocarbons traces, avoiding any ground contamination.
Outflow Filtered: Approximately 110 Litres per Minute.
Industrial equipment or storage units containing hydrocarbons must be equipped with a bund or retention tank. Tanks installed outdoors must be drained of water regularly, and can release oil in the rainwater. The Petro Pipe PI-616 is a cartridge specially designed to be placed in all kinds of tanks, allowing rainwater to drain while retaining all hydrocarbon traces, preventing ground contamination.
Rainwater Outflow: 16 Litres per Minute.

Thanks to its hydrophobic component, PETRO PLUG lets water pass but prevents oil escaping. In case of an oil leak the active product solidifies immediately, avoiding any polluting discharge. Sized for small flow rates, Petro-PLUG® is used in a vertical position.
