Collection – Vacuum Toilet System
We offer vacuum collecting units for all types of buildings and institutions. The vacuum collecting units create a powerful vacuum and are optimized for each application. The units have been designed to work reliably under heavy duty conditions and to bring energy saving benefits. They are designed for installation as part of the chain that makes up the waste water collection and transport.
In addition we offers a variety of vacuum toilets for different applications. Typical features include a water-saving flush, elegant design, reliability and low sound level in use. Toilets are available in porcelain and in robust stainless steel, and the range includes shock tested and squatting toilets. Interface valves are available to connect gravity lines to the vacuum piping system.

Vacuum generation

Evac OnlineMax
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 sanitary installations. The OnlineMax pump offers significant long-term operational savings.

Multiple advantages are:

High-capacity, low-footprint design
Quick and flexible installation
High energy efficiency
Simple, fully automatic operation
Robust design and quality, reliable components
No foaming and no need for antifoaming chemicals
No collecting tank needed
Vacuum performance independent of discharge head
Discharge up to 20 metres
No cooling or sealing water

Evac Vacuüm Tank Units
Vacuum tanks are the original technology first and most used.
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.

Benefits of the Evac EcoVac tank are:

Modern compact design with optimized components
The best efficiency in energy consumption
High capacity with small footprint
Wastewater holding capacity
Additional vacuum volume in the tank
Available with different vacuum capacities

Evac Ejector Units
The ejector vacuum collecting units are made using proven, robust technology, which is simple and reliable and still present a good option for certain applications.  They have fewer moving parts than other solutions, making them extremely low maintenance.
Ejector vacuum collecting units have a flexible design offering a large number of different possible variations and holding tank alternatives.
The ejectors’ aeration effect on sewage means that there is no need for additional aeration of vacuum collecting units.  This means no hazardous H2S gases and/or odors from the aerobic waste water process.
