Chemical Source Switching

The Chemical Source Switching System from Landry Engineering, Inc. is an in-line, fluid control system that provides uninterrupted chemical flow to a process tool or supply header. It eliminates process tool interruptions and wait times due to an empty chemical source.

In standard configuration, it operates with two ATMI® NOWPak® pressure-dispense chemical containers, controlling container pressurization and chemical flow. It features a 100% Teflon® (PTFE, PFA) wetted path. Automatic switch over occurs with no change in pressure or flow. Chemical containers are virtually emptied and the associated bubbles are captured and eliminated.

Alternate configurations are available for direct pressure or pump-draw systems and high or low flow rate systems as well as Class I, Division II installations.
