The feedback fromthe “Crystal Harmony” crew is that thepumps function well and build up thevacuum effectively. They have startedoverhauling the pumps, changing bearings,macerators and mechanical seals, but thiswas only required after three years ofintensive operation.The collecting tanks are no longer used,and foaming has become a foreign word.“CRYSTAL HARMONY”A module withtwo Vacuumaratorswas installed toreplace the ejector units.We used the existing piping onthe collecting tank to connectthe retrofit Vacuumarators.After connecting the inlet andoutlet, the retrofit was readyfor operation.The transparent coversmake it easy to checkthat the system isfunctioning smoothly.15

Manycruise ships have installedplug-in modules with 2, 3 or 4Vacuumarators, without eveninterrupting the ship’sregular operation.And the Jets solution startsreducing costs as soon as itis in operation.
