Abstract
An LNG refueling facility includes a nozzle for mating with the receptacle on a motor vehicle to deliver a flow of LNG to the vehicle's tank. The nozzle is supplied with a flow of dry gas to purge moisture-laden air from around surfaces which mate with the receptacle to prevent freezing of moisture on the mating surfaces when the nozzle turns very cold. The nozzle also includes a boot enclosing mechanical linkages for latching the nozzle to the receptacle. Dry gas is supplied to the interior of the boot to displace air from around the mechanical linkages and thereby prevent moisture from freezing onto the mechanical linkages.
