The current disclosure relates to example method, system and apparatus for coupling a delivery vessel disposed at a first location on a substrate processing platform to a remote refill vessel disposed in a second location remote from the substrate processing platform via a first chemical delivery line, storing a chemical in the remote refill vessel in a first phase, changing the chemical in the remote refill vessel to a second phase, transporting the chemical in the second phase, to the delivery vessel via the first chemical delivery line, heating the first chemical delivery line to a first temperature equal to or above a phase change temperature of the chemical, and coupling the delivery vessel to an accumulator via a second chemical delivery line.
