GEA Mechanical Equipment engineering for a better world

Cost saving has become a very attractive

proposition on board of ships as the

operating costs have risen sharply.

The overall economy and less consump-

tion of fuel are essential to be more

competitive and to operate a green and

environmentally friendly vessel.

In traditional lube oil treatment systems

the energy for heating the lube oil

upstream of the centrifugal separator is

lost, because after separation the hot oil

goes back to the engine sump tank to be

cooled by the engine cooling system.

As an integral part of the lube oil treat-

ment system in compact unit design the

GEA Westfalia Separator EnergyMaster

re covers part of this energy. The recovery

heat exchanger is the heart of this system

and designed as a brazed plate heat

exchanger.

The GEA Westfalia Separator

EnergyMaster is available as

• An intergrated part of the heater

unit, HRU

• A retrofit package for existing

heater units

The return of investment period is out-

standing short even for retrofit systems.

The cold dirty oil inlet to the separator system is

pre-heated by the recovery heat exchanger before

the dirty oil is heated up to separating temperature

by the standard steam, thermal oil or electric pre-

heater. The hot clean oil outlet of the separator

is used for pre-heating the cold dirty oil inlet. The

footprint is not larger with separator systems in

compact unit design. The system contains a brazed

plate heat exchanger, a mounting plate, by-pass

lines and isolating valves.

The GEA Westfalia Separator EnergyMaster is easy

to handle, self-regulating and maintenance free.

The GEA Westfalia Separator EnergyMaster saves

the energy on the separator preheater system and

the same energy is saved on the engine lube oil

cooling system.
