Pattons Medical IntelliSwitch Cost-savings Features Explained : Economizer and Look-Back Feature

ECONOMIZER FUNCTION

When using liquid cylinders in switchover application, it is common for the reserve cylinder to build pressure due to the vaporization of liquid within the cylinder. When this pressure reaches the set point of the relief valve on the liquid cylinder, the relief valve will open, venting gas to the atmosphere.

The IntelliSwitch constantly monitors the reserve cylinder and, at a predetermined pressure, will change the valving to allow gas from the headspace of the reserve cylinder to feed the system, thus drawing down the pressure in the reserve cylinder.
