In some ships installations, there is not enough waste heat available, and if high fresh water quantity is required, the double stage units are the best solution for big water production at low energy consumption.

We have based our design on the highly successful single stage models. The used method for water evaporation of this double stage unit is illustrated on the below flow diagram.

The distilling plant consists on two evaporator stages made in two independent chambers.

Each chamber has a submerge tube heater at the bottom, and one condenser on the second chamber.

The generated steam on the first chamber in use to warm-up the second stage heater.

The condensation produced inside the heater tubes is recovered via one steam trap by the distillate water pump.

This condensed water is the extra production that we can get using the same amount of thermal energy.

Distilling plants were designed to operate with waste heat from diesel engines jacket cooling water, any how the units can operate whit other heat sources, like steam or combination of both systems.

The Watermakers are based on the principle that the sea water can be evaporated under a high vacuum at temperatures as low as 40ºC.

The units is designed to use a waste heat source like the engine jacket water from main engines or auxiliary diesels.

Any other kind of heat can be used as heating medium, such as steam, thermal oil, etc.

The Fresh Watermaker is a compact assembly ready for installation on board. The heater and condenser are located inside the housing and separated by a demister which prevents small salty water reach the condenser.

The distillate water vapour after their

Condensation is removed from the unit by the distillate pump..
