According to one embodiment, a vaporizing system comprises first and second tanks that can accumulate liquid source and first, second, and third pipes. The first pipe allows first gas to be sent out of the first tank. The second pipe allows second gas to be sent out of the second tank. The third pipe is connected to the first and second pipes and allows the first and second gas to be sent out to an external apparatus. The first tank is placed on an upper side of the second tank in a stacked manner.

Humidifier apparatus for a respiratory apparatus includes a housing providing a gas flow path, a heater apparatus, and a water supply distribution member configured and arranged to deliver water vapour to the gas flow path. The water distribution member is provided to the housing and in thermal communication with the heater apparatus.

A fuel management module for use with a CNG fuel system for a vehicle includes a housing configured to be connected to the vehicle and a number of connections, receptacles, and controls associated with the module. A defueling receptacle may be positioned on the front panel of the housing, for defueling a fuel tank of the vehicle. A defueling control valve may be positioned on the front panel of the housing for controlling operation of the defueling receptacle, allowing for selective defueling. One or more high pressure connections may be accessible on the housing and configured for connection to one or more separate fuel tanks in a plug and play configuration. A plurality of filling connections may be accessible on the housing for filling the fuel tank(s). A low pressure fuel output connection may be positioned on the back panel of the housing to provide fuel output from the high pressure connections to the engine.

A high-pressure vessel unit includes: plural cylindrical vessels arrayed inside a case, with end portions of the vessels on one side in the axial direction thereof being equipped with openings; a coupling member connected to the openings of the vessels to couple the plural vessels and includes a flow passage that communicates the insides of the vessels; a lead-out pipe that is leads out to the outside of the case from the coupling member through a through hole formed in the case; securing members that secure the coupling member to the case; and a retention mechanism that retains portions of the vessels on the axial direction other side of the end portions on the one side in the axial direction such that those portions of the vessels on the axial direction other side are movable in the axial direction relative to the case.

A modular tank system comprising at least two pressure tanks (1,1) and a mounting frame (2), wherein each of the pressure tanks (1,1) comprises a pressure vessel (3) and a protection frame (4) within which the pressure vessel is arranged, the protection frame (4) is adapted such that multiple pressure tanks (1,1) may be mounted on top of each other and the pressure vessel comprises a vent outlet and a first inlet (5), wherein the vent outlet is arranged in an upper half of the pressure vessel, the first inlet (5) is arranged in a lower half of the pressure vessel and is fluidly connected to a tank process line (6), the tank process line comprises a first fluid connector (12) and a second fluid connector (23) on opposite ends of the tank process line, such that the second fluid connector (23) of a first pressure tank (1) is connectable to the first fluid connector (12) of a second pressure tank (1), when the second pressure tank (1) is mounted on top of the first pressure tank (1); and the mounting frame (2) comprises a base frame (15) upon which the at least two pressure tanks (1) may be mounted, the base frame comprises a frame process line (16); the frame process line (16) comprises at least two fluid connectors (20), each fluid connector (20) connectable to the first fluid connector (12) of a tank process line (6) and arranged such that the frame process line (16) may be fluidly connected to the tank process lines (6) of the at least two pressure tanks when the pressure tanks (1) are mounted upon the base frame (15) side by side.

Each of the tanks includes a pressure vessel and a protection frame within which the vessel is arranged, the protection frame is adapted such that multiple tanks may be mounted on top of each other and the vessel includes a vent outlet and an inlet, where the outlet is arranged in an upper half of the vessel, the inlet is arranged in a lower half of the vessel and is fluidly connected to a tank process line, which includes a first fluid connector and a second fluid connector on opposite ends of the tank process line, such that the second connector of a first tank is connectable to the first connector of a second tank, when the second tank is mounted on top of the first tank; and the mounting frame includes a base frame.

A trench is dug under an above ground water storage tank either before erection of the walls or after the wall is erected. A (rectangular) sump is preferably made of ? inch steel. It serves as a conduit from an inner tank liner port to an outside tank fill or drain port. The system eliminates hoses hung over the top edge of the tank wall. A pump can fill the tank from the outer port. The tank can be drained using head pressure of the water and/or a pump.
