Gregory Sachs of the Merchant Marine Institute, who has a hydrogen installation very similar to ours, uses a clever passive switching mechanism: His K-cylinder of hydrogen has a pressure regulator set to 40 psi, and the cylinder is always open. When his storage tank empties to the point that its pressure goes below 40 psi, the K-cylinder line has the higher pressure, and starts supplying fuel.<\/p>\n\n\n\n<p>Although the manifold does not require additional pressure regulators for hydrogen K-cylinders, we have regulators for both nitrogen and hydrogen, for testing and purging (Thermadyne SR450E-580 and SR452E-580).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"267\" height=\"200\" src=\"https:\/\/web.siei.org\/wp-content\/uploads\/2020\/12\/manifold_h_200.jpg\" alt=\"\" class=\"wp-image-145\" srcset=\"https:\/\/www.siei.org\/wp-content\/uploads\/2020\/12\/manifold_h_200.jpg 267w, https:\/\/www.siei.org\/wp-content\/uploads\/2020\/12\/manifold_h_200-200x150.jpg 200w\" sizes=\"(max-width: 267px) 100vw, 267px\" \/><figcaption>The manifold.
