A dispensing unit is provided having a circulation system for circulating a fluid in the dispensing unit is provided. The circulation system can include a circulation circuit, and a mechanism configured to circulate the fluid in the circulation circuit. By circulating the fluid, the fluid is counteracted from crystallizing. A method for circulating a fluid in a dispensing unit is also provided.

Disclosed is a beverage dispenser including a housing having a beverage storage space capable of storing a volume of a beverage to be dispensed and a heat exchanger sub-system operable to effect the temperature of a beverage stored in or passing through the beverage storage space. The housing is provided with at least one wall through which beverage in the beverage storage space can be visualized. The dispenser includes a coupling enabling the coupling of a valve to facilitate dispensing of beverage from the beverage storage space.

A method of controlling heating of hot melt adhesive within a hot melt dispensing system includes receiving input AC electric power, determining on a half cycle-by-half cycle basis which heaters in a plurality of zones will receive AC electric power during the next half cycle, and distributing the AC electric power to the heaters on a time sharing basis.

A side by side cartridge assembly for dispensing first and second fluid materials includes a first cartridge container and a second cartridge container. The cartridge containers include respective bodies and nozzle members coupled with the bodies. The cartridge containers are positionable with respect to one another such that the two nozzle members cooperate to form a cartridge outlet for dispensing first and second fluid materials from the respective bodies. The cartridge outlet includes dispensing openings communicating with respective nozzle channels, and a sealing surface configured for sealing engagement with a mixing element when a mixing element is attached to the cartridge outlet.

Devices, systems, and methods for thermally regulating and dispensing beverages are described herein. More particularly, in one aspect, jackets for thermally regulating a beverage container are described. Such a jacket can comprise an interior temperature control layer defining an interior space for receiving the beverage container, and an exterior fabric layer disposed over the interior temperature control layer. The interior temperature control layer comprises a first phase change material (PCM) having a first phase transition temperature corresponding to a desired service temperature of a beverage contained in the beverage container.

According to aspects, hydrogen fueling systems and methods are provided, including vehicle-to-vehicle communication techniques, hydrogen cooling techniques and/or hydrogen dispenser control techniques that facilitate improving aspects of a hydrogen fueling station.

A domestic beverage dispensing device includes a conduit for supplying the beverage from keg to a tap and a cooling member. The cooling member has a passage surrounded by heat conductive material. A disposable tube of deformable material forms at least a part of the conduit and extends through the passage. The deformability of the material of the disposable tube is such that the outer surface of the wall of the tube abuts against the inner surface of the passage when the beverage is pressurized.
