Upon the introduction of nominal amounts of oil in the tank, it mechanically shuts the inlet closed (with 16 feet of total dynamic head or 0.5 bar) thus containing the oil spill upstream. When conventional oil spill control valves close the outlet pipe, the tank can continue to fill up due to the accident and it eventually overspills through the manhole causing environmental disaster downstream. Such damage is very costly to clean up. The EcoStop valve has a true and tested 99.9 % reliability track record. No electrical requirements. It can be installed with our optional AC or DC alarm systems using internet protocols to immediately send operators electronic messages advising which tank in particular requires attention.
Experience has taught us that it is not uncommon for employees responsible for visually inspecting tanks after storms and other accident causing events, often time fail to carry out such duties and in fact, in some cases, actually force the conventional oil spill prevention valves to remain open. This 'obviates' their perceived need for continued and regular visual inspections thus exposing the owner to expensive clean up costs and legal liability. The EcoStop valve avoids such 'human error' and provides peace of mind. A must for oil companies, gas/fueling depots and electric power plants.
The Ecostop Spill Control System is designed to control spills at petroleum storage or fueling facilities. A spill situation shuts down Ecostop‘s closure valve, preventing the discharge of free oil to municipal sewers or direct discharge outfalls. Ecostop maintains the spill on site where it can be contained either below grade (i.e. an underground storage tank or a large diameter pipe) or in an above grade, diked area. The capacities of this upstream storage reservoir should be large enough to accommodate typical amounts of a tank truck oil-spill (with an additional capacity, safety factor).
The downstream Ecostop tank is equipped with Ecostop‘s automatic shut-off valve (patent pending). This float actuated closure device stops the flow through the system when the maximum oil storage capacity or a certain liquid level in the Ecostop chamber is reached. In its closed position, the valve is watertight up to 0.5 bar (5m water column). The Ecostop detects spills automatically and therefore eliminates the most common failures in traditional spill control systems, human error.
In the event of a minor petroleum build-up or a catastrophic type spill, changes in the liquid levels can be monitored by accurate and reliable liquid level sensor alarms.
The system is installed in-line and downstream from any segregated petroleum containment drainage area treating runoff.
Ecostop comes pre-installed in a standard precast concrete manhole or in an Ecosep Oil/Water Separator. Ecostop can be retrofitted to an existing drainage system.
Any facility or site, where the potential for a petroleum spill exists:
- Gasoline stations and other fueling facilities
- Electrical transformers
- Oil storage areas
- Transportation fueling systems
Catastrophic oil spill control
An inlet shut-off valve (patent pending) makes Ecostop the industry standard in providing the highest environmental protection against discharge of petroleum spills at your facility.
Watertight to 0,5 bar pressure (16 feet TDH)
The outstanding test results achieved at noted testing institutions show that Ecostop will be able to meet even tougher future standards.
High operational reliability
No external energy supply is required, no electrical parts and constructed only of stainless steel components.
Easy to install
The system is prepackaged in a standard precast concrete manhole.
Easy to retrofit
To existing concrete separators or manholes.
An investment that is built to last
Due to the use of stainless steel components and high strength precast concrete hosts.
