Evoqua offers various automatic changeover modules to ensure an uninterrupted and unattended changeover to a fresh gas supply when the on-line supply is exhausted. Once a storage container reaches a specific low level, changeover module switches to the next available full tank or bank. This means all available chemicals are optimally utilized.
There are three types of changeover units available in Wallace & Tiernan® portfolio depending on the type of installation. Changeover may occur on vacuum gas line, pressurized gas line or liquid line. Please refer to the attached brochure or contact Evoqua Water Technologies for more information.
