Operating Principles> Mattei Condensate Drains


How Mattei drains work.

The condensate seperated from the compressed air system flows into a collecting tank where a level sensor continuously monitors the condensate level. When the condensate level reaches the upper sensor threshold, the solenoid valve opens for the programmed time until the condensate level has dropped to the lower sensor threshold. The condensate is exhausted from the collecting chamber. Because a small amount of condensate remains in the tank when the valve closes, no compressed air reaches the condensate outlet.

The alarm is activated if a fault arises due to excessive amounts of condensate (overload) or blockage of the drainage line. A flashing LED indicates alarm status. In alarm status the drainage valve remains open in order to continue draining the condensate from the collecting tank as much as possible. The electronic control system reverts to normal operation when the level in the collecting tank is back to normal.
The condensate then flows into a Mattei oil-water seperator which processes the condensate so it can be legally discharged.
