Poseidon® FAQ’s

The old ~200 GPM rule of thumb assumed a nozzle with heavy friction loss (up to 100 psi). Poseidon has very low friction loss. Its combined outlet area is much larger than the inlet, so there's almost no back pressure. Modern hose linings help too. We verified flows with an FRC FTA400 flow meter after calibrating it against a standard SM20 fog nozzle. With a positive water supply it flows 400+ GPM on 100 ft of 1¾"; the exact results are in the flow table on the Poseidon page.

You can. With a 2½" line Poseidon flows over 500 GPM. But a 1¾" is easier to move and is what most crews pull first, and it already gives you 400+ GPM.

Poseidon sprays from the top and sides, spreading water across the underside of the vehicle. A few large jets look impressive in the open, but much of that water bounces off at high velocity. We built Poseidon for wide, even coverage.

Any metal, steel included, can be damaged at the temperatures a vehicle fire can reach. That's why Poseidon is meant to be flowing while you deploy it. The water keeps the nozzle cool, and the spray acts like a fog pattern between you and the heat. We chose 6063 aluminum to keep the nozzle at 18 lb so it can be handed down safely from a top compartment, and because it won't rust where paint wears off the way steel does.

18 lb with the 38" deployment pipe, made of 6063 aluminum. 2½" tall, 42½" long and 12" wide.

Poseidon is 2½" tall. Many EVs sit lower once the tires fail.

Poseidon works on a standard 1¾" or 2½" line. Crews often start at idle on tank water (200+ GPM, without draining the tank), then, once a positive water supply is established, increase flow to 400+ GPM. With a 2½" line you'll get over 500 GPM. See the flow table on the Poseidon page for exact figures.

Seconds. Attach the pipe, open the line, and push it in from any side while it flows, so firefighters stay out of the dangerous hot gases an EV gives off.
