Evac EcoVac

The Evac EcoVac units are ideal for black and gray water collection on large application. Vacuum tank systems consist of a tank with a typical capacity of 1–3 m3, vacuum pumps, and sewage discharge pumps.

Vacuum tanks have become relevant again as a result of improvements in production methods and the emergence of robust vacuum pump technology. Excellent energy efficiency, the best feature of vacuum tanks, is today more important than ever.Unlike online vacuum pump systems such as the Evac OnlineVac, sewage is collected in the tank and discharged in batches. As with OnlineVac, the vacuum is created by special vacuum pumps, but the vacuum tank also acts as a large stabilizing vacuum buffer for the system.

In a system with an Evac EcoVac unit, the whole tank is under vacuum. Vacuum generation is controlled by a vacuum sensor and the PLC. Discharge is controlled by high and low-level switches or, optionally, by a timer.
