Saving Waste Energy

摘要

As of the start of October 2008, Finnish company Evac was able to claim 31 references for its new Onlinemax vacuum generation backplate system, either as test installations, as retrofits or on newbuilds, aboard 20 different ships. The OnlineMAX concept has been designed to meet the growing need for larger and more energy-efficient vacuum capacity on large passenger vessels. With a payback claimed at between two and three years, installation of the new system can be executed by ship crews during the cruising time, with no yard necessarily involved. In the case of a retrofit, only three connection points are required from Onlinemax to the existing tank and manifold. Onlinemax is installed close to the existing waste collecting unit alongside the ejectors (normally four) and it takes up about 1m~2 of space. The existing units are still there, as are the tanks, while the existing ejector pumps are still used for discharge purposes.
