Evac OnlineMax R
Online double-stage vacuum generation unit

The Evac OnlineMax R is the most powerful and energy-efficient online vacuum collection system on the market. The Max concept was designed as an energy efficient way to meet the increasing demand for larger vacuum capacity in vacuum toilet systems on large vessels such as cruise ships. The Evac OnlineMax R offers significant long-term operational savings – the bigger the vessel, the greater the cost efficiency.

In the double-stage vacuum (DSV) system, the air/sewage mixture is divided into separate sewage and air phases. Because each phase is handled by a separate specialized pump rather than by common, non-optimized pumps for both phases, the system is much more efficient.

Benefits

  • High-capacity system with a small footprint (1 m²/10.76 ft2)
  • Suitable for both new builds and retrofits
  • Quick and flexible installation
  • High energy efficiency
  • Simple, fully automatic operation
  • Robust design with high-quality, reliable components
  • No foaming means no need for antifoaming chemicals
  • No collection tank needed
  • High discharge head of up to 20 meters/65.61 feet
  • No sealing water required, meaning lower fresh water consumption

 

 

 

Materials:

  • Vacuum pump; pump casing: cast iron, PTFE coated inside
  • Sewage pump; pump casing: cast iron
  • Frame: Steel S335 (ASTM A572)
  • Piping: Acid proof steel, EN1.4404 (AISI 316L)

The Evac OnlineMax R vacuum collection unit is optimal for large vacuum systems with high flow capacity requirements and no redundancy requirement. The unit requires compressed air supply.

In the double-stage vacuum (DSV) system, the air/sewage mixture is divided into separate sewage and air phases. Because each phase is handled by a separate specialized pump rather than by common, non-optimized pumps for both phases, the system is much more efficient.
