Company unveils device to meet emissions standardsPosted on
Herrington Marine Technologies recently introduced a new device to enable boatbuilders to meet diurnal emission standards set by the Environmental Protection Agency.
Builders have the option of creating their own solution for capturing hydrocarbons regulated by the EPA or using companies such as Attwood, Perko and now Herrington.
Washington-based Herrington said its EPA-certified E-Valve pressure relief manifold creates an effective and economical solution to EPA evaporative emission standards.
The E-Valve manifold operates with a bi-directional valve system, permitting non-restricted air flow to the fuel system during engine operation. While sealing off the fuel system vent when the vessel is not in use, the E-Valve will operate in either the horizontal or vertical position.
Made of corrosion-resistant components, the 1-pound unit measures 9.5 by 3.5 inches, fitting a 5/8-inch hose. It meets and exceeds a Coast Guard requirement and is compliant with National Marine Manufacturers Association and American Boat and Yacht Council standards.
The manifold also reduces fuel system moisture accumulation. Today’s ethanol and biodiesel fuels can absorb as much as 300 times more moisture than traditional petroleum-based fuels.
