Evac EcoVac vacuum tank
The Evac EcoVac offers excellent energy efficiency which today is more important than ever. EcoVac units are ideal for black and gray water collection on board large vessels, making them an excellent option for cruise ships. Vacuum tank systems consist of a buffer tank with a typical capacity of 1m3, vacuum pumps, and sewage discharge pumps.

Unlike online vacuum pump systems such as the Evac OnlineMax R or liquid ring pumps, sewage is collected in the tank and discharged in batches. As with OnlineMax R, the vacuum is created by special vacuum pumps, but the vacuum tank also acts as a large stabilizing vacuum buffer for the system reducing the number of startup cycles needed.
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.
