    Evac OnlineMax - Vacuum Collecting Units

    The Evac OnlineMax is currently the most powerful and energy efficient vacuum collecting system on the market. The Max concept was specially designed as an energy efficient way to meet the continuously increasing demands for better vacuum capacity on large vessels. The OnlineMax pump offers significant long-term operational savings – the bigger the vessel, the bigger the financial benefit.

  • Evac - Vacuum Tank Units

    Evac - Vacuum Tank Units

    Vacuum tanks are the original technology first used on board marine vessels. Vacuum tank systems consist of a vacuum tank (normally 1-6 m3 in capacity), vacuum pumps and sewage discharge pumps. Unlike the OnlineMax, for example, sewage is collected to the tank and discharged in batches. As with the OnlineMax, vacuum is created by special vacuum pumps but the vacuum tank also acts as a big vacuum buffer for the system.

  • Model QUA-VAC MDQ - Automated Dosing System

    Model QUA-VAC MDQ - Automated Dosing System

    Qua-Vac designed a unique dosing system for vacuum pipe lines to remove or prevent clogging caused by organic materials such as limestone. The system requires only a standard electrical plug connection and works fully automatic. Fluids are dosed into the pipe lines by using the vacuum. These two non-toxic and biologically degradable fluids either remove or prevent (depending on which fluid is used) blockages of an organic nature. This means our one...
