MECO Vapor Compression (VC) desalination units are designed to produce high quality distilled water or potable water from a seawater source. Our desalination units are designed and constructed with the harsh environment in mind, only the highest quality materials are used. MECO VC stills have a smaller footprint with easy access for maintenance.
In addition, each comes equipped with the MASTERedge Package, a system of features that provides even greater value. You also benefit from the expert and responsive service delivered through MECO's MASTERsupport service capabilities.

Natural Circulation Evaporator
|
|
|
|
MECO's vertical arrangement allows the feed water to be on the inside of the tubes yielding numerous benefits to operation and maintenance. Feedwater boiling on the inside of a tube (percolation) allows the flow to travel up the inside diameter of the tube and return to the base of the evaporator via an internal downcomer. The natural circulation evaporator design eliminates the need to force circulation using pumps and spray nozzles, which increase both operating and maintenance costs.

Feedwater Deaerator
|
|
|
|
By deaerating the feedwater, MECO removes oxygen which a primary contributor to corrosion. Non condenible gasses which would otherwise inhibit heat transfer are vented to atmosphere, eliminating the need for a vent condenser that would be a source of additional corrosion and maintenance.

|
MECO Centurbo Vapor Compressors are single stage units with inconel or titanium impeller and monel shaft. Lubrication is provided by way of a forced feed oil system including pump, cooler, pressure and temperature monitors. Only MECO Centurbo compressors are fitted with the proprietary Lube Lock Seal System (LLSS).
