Evac OnlineMax The Superior Vacuum Pump
The Evac OnlineMax is the most powerful and energy efficient vacuum collecting sustem for shipboard toilet systems ever made.
Designed using robust mechanical components, the Evac OnlineMax pump creates and maintains constant vacuum in the piping of a ship's vacuum toilet system. The Max concept was specially designed as an energy efficient way to meet the continuously increasing demands for better vacuum capacity on large vessels. Today's high energy prices and environmental concerns have lifted energy efficiency to the fore, especially when considering units in continuous operation. Ships are getting bigger, and the large scale vacuum production offered by the Online pump offers significant long-term operational savings - the bigger the vessel, the bigger the financial benefit.
Through better energy efficiency and lower operating costs than low-performance competitors, the Evac Online Max Effectively finances itself in 2-3 years.

Waste & Wastewater treatment
Vacuum systems also lend themselves to the recycling of gray water. Once again the flexibility of the vacuum system allows you to bring all the grey water from the building back to one location, for forwarding to your treatment plant.
Evac can offer a wide range of sewage treatment plants from biological sewage treatment plants to membrane bioreactors for recycling gray water to be used as toilet flush and irrigation water or the safe disposal of black water. The plants have been designed to minimize technical problems and to maximize total process reliability.
Evac MBR
The Evac membrane bioreactor – MBR systems allows private yachts, cruise liners, ferries, naval vessels and others operating in environmentally sensitive areas to treat and discharge all waste water generated by passengers and crew, at sea, without threat to health or the environment. It is based on proven, very low maintenance membrane bioreactor technology, which is capable of filtering out particles as small as viruses. Its compact footprint makes it ideal for retro fitting to existing vessels as well as for installing on new ships.
The Evac MBR is an advanced wastewater treatment process where the waste water streams are treated to meet all current and future standards. |

Waste treatement without polluting the air, land or sea
A specialist in waste treatment on cruise ships, Norsk inova installed the world's first three deck incinerator system on board the 'SS Norway' in 1979 - followed by the first integrated incinerator/food waste/recycling system installed aboard the 'MS Sovereign of the Seas' six years later. As thousands of passengers and crew generate huge amounts of waste aboard a cruise ship, the limited space available for storage makes the waste treatment plant one of the most important piece of machinery and logistics systems aboard. Norsk Inova located in Notodden, based in NOtodden in Norway, is a major manufacturer and vendor of complete waste handling and treatment systems for cruise ship applications. The company supplies technical solutions and services to both new buildings and to the sailing fleet. Far from standing still, the company is continuously working on waste treatment equipment. A lot of improvements have been introduced in recent years. These include the 'Green Ship Concept' first introduced in 1990, which has become a standard for environmentally aware cruise ship owners, and a flue glas cleaning system capable of complying with the world's strictest regulations.
