Hydro Changeover Systems

Mechanical Switchover or Automatic Changeover System
HYDRO changeover systems have 2 models as Mechanical Switchover or Automatic Changeover systems depending on the need and purpose of chlorination systems.
Automatic Changeover Systems, consisting of controller, line pressure gauge and electrically actuated ball valve, Automatic Changeover Systems, consisting of controller, line pressure gauge and electrically actuated ball valve, receive a low pressure alarm signal indicating that the gas supply is exhausted when the drums / collector line in operation are exhausted, and the controller closes the ball valve in use and opens the ball valve in standby.
The mechanical switchover unit is placed in the vacuum line and cannot receive any signal. When the vacuum in the operated vacuum line is reduced, it provides a transition to the standby line, thus ensuring constant gas flow.
