Automatic Fuel Oil Purification System , Heavy Fuel Oil Filtration System

Strainer and filter

automatic fuel oil filter systems provides effective full-flow filtration of fuel oil (FO), heavy fuel oil (HFO) and marine diesel oils (MDO) up to 700 cSt/50°C. These fuels are widely used in modern two-stroke and four-stroke diesel engines, and the quality and cleanliness of such fuel has an important influence on engine efficiency, fuel consumption, reliability and service life.

This range of automatic fuel oil filter systems only requires very limited investment yet helps ensure reliable engine operation, along with peace of mind for those dependent on the engine working as intended. The robust, space-saving design makes these units easy to install as well as to retrofit as upgrades to existing installations.

These units use fuel oil that has already been filtered to backflush the filters, doing away with any need for a compressed air supply. This backflushed oil is then cleaned by refiltration in a special filter-equipped diversion chamber (which also uses the same backflushing principle) before being recirculated into the system. This diversion chamber acts as an automatic maintenance-free sludge treatment system, collecting and concentrating the particles backflushed from the full-flow chamber and the subsequent cleaning process into a concentrate sludge.

Description:

1.  Filtration

The fluid to be filtered flows through the

filter elements of the back-flushing filter,

passing from the inside to the outside.

Contamination particles then collect

on the inside of the filter elements.

As the level of contamination increases,

the differential pressure between

the contaminated and clean sides

of the filter increases.

When the differential pressure

reaches the pre-set trigger point,

back-flushing starts automatically.

Triggering back-flushing

Automatic back-flushing is triggered:

– When the differential pressure

 trigger point is exceeded,

– By means of an adjustable timer

– By pressing the TEST button.

2. Back-flushing

- The gear motor rotates the flushing arm

 under the filter elements and ensures

 the contamination is discharged

– The contamination is flushed away

 through the open back-flushing valve

The pressure drop between filtrate side

and back - flushing line flushes a small

amount of the filtrate back through

the contaminated filter elements.

The contamination particles collected

on the inside of the filter elements

are loosened and flushed into the

backflushing line via the flushing arm.

After the "back-flushing time per element"

has expired, or after one revolution

(EU version), the back-flushing valve

is closed. In this way, all the filter elements

are back-flushed, one after the other.

A back-flushing cycle is terminated once

all filter elements have been cleaned.

3. Pulse - aided

back-flushing

On the control types EPT and PT,

the flushing arm remains under the filter

element for only a few seconds.

Rapid opening of the pneumatic

back-flushing valve generates a pressure

surge in the filter element openings,

and supplements the cleaning effect

of the back-flushing process.

The back-flushing valve opens and

closes during back-flushing of each

filter element (back-flushing volumes

are lower in pulse-aided control).
