The system forces water through specially designed misting nozzles creating a fog of ultra fine water droplets which can instantly flash evaporate and reduce the surrounding temperature as much as 30 degrees in just seconds. The system uses a booster pump that draws only one amp, delivers 130 psi and keeps a flow rate as low as one gallon per hour depending on the number of nozzles installed. "Push to Connect" tee connectors splice right into the boats on-board water lines. We offer a 7 gallon hard plastic container or a 5 gallon collapsible container (see all availbale accessories below) NOTE: Systems can also draw water from most fresh water lakes.
