Soot filter UGET 3

Description

Exhaust Gas purification is ever evolving technology, and for this reason, Bersy is continually improving their range of exhaust gas purification systems in order to offer the most advanced, long lasting and reliable solutions.
After many years of research and development into improving exhaust emissions, Bersy now presents this innovative exhaust gas filtration system.
UGET 3 is a dry particulate filter system capable of reducing by 90% carbon particles emitted from the exhaust of a diesel engine and it operates immediately from engine start-up.
The environmental advantages are obvious, enabling our customers to meet the very stringent regulations laid down by Government Health and Safety executives.

Operating principle

Very fine unburnt carbon particles are responsible for the typical black smoke emitted from a diesel engined exhaust. They are the main cause of many respiratory illnesses and also have a damaging effect on the environment. These negative effects are compounded when diesel vehicles are used in confined spaces or in close proximity to human beings (i.e. tunnels, mines, quarries or in factories and warehouses).

Operating plan

UGET 3 filter housing is made of stainless steel and encompasses a heat shield for protection against burns. The filter element or cartridge is made of special fibres that are contained in a carbon steel structure and fit inside the filter housing.
The filter cartridge is fire and heat resistant and also resistant to aggressive elements contained in the exhaust gases.
The texture weave of the special fibre retains carbon particles from as small as 0.3 microns.
The filter complete with the housing, which also acts as a muffler or silencer is fitted as part of the exhaust system and the exhaust gases passing through the fibre glass filter material collects the carbon particles and retains them in the filter element allowing the remaining exhaust gases to pass through. The filter element has a capacity of 1000 grams before needing to be replaced.
UGET 3 filters are available in varying sizes and are supplied complete with cartridge(s) ready for instant use.
Apart from the standard models shown here, Bersy are able to produce units suitable for even larger engines to suit customers individual needs.

Fitting Instructions

Maximum operating temperature is 350°C. Bersy recommend that the UGET 3 filter is fitted as far away as possible from the engine to avoid any problems of the filter getting too hot.
It is suggested that the filter housing is anchored to the vehicles frame or body with fixing brackets and connected with a piece of flexible pipe to the exhaust pipe using the counter flanges supplied.
As the filter assembly acts as a silencer as well, there is no need for the muffler on the machine to be used and this should be discarded.

Maintenance

The filter does not need planned maintenance.
At the end of the filter cartridge life the back plate is removed to extract and replace it with a new one.
Disposal of the used cartridge is straight forward as it is not classed as hazardous waste but it has to be disposed of as special waste.

Filter life

The life of the filter element is approximately 300-350 hours of use, depending on the condition and maintenance of the engine.

Opacity Tests

Opacity Tests have been carried out on an 80 Kw supercharged engine.
Recorded values are expressed in percentage terms and represent the values of five efficiency tests made on the same engine.
The graph below shows the percentage reduction at three different stages during the life of the filter.

Back Pressure Tests

Back Pressure tests have also been carried out to record the restriction caused by the filter at different stages of its life.
The graph shows these based on three different stages in the elements life.

Safety protection system

To ensure correct and improved functioning of the system there is a safety device available.

Backpressure valve

Over-temperature valve

By-pass valve

Backpressure valve

The Backpressure valve has been introduced in order to protect the filter and the engine from excessive backpressure.
This valve starts to function if and when there is a sudden increase in pressure in the exhaust system, or when the filter reaches its maximum capacity.
The exhaust gases go out through the valve. This situation allows the operator to rectify the problem without causing damage to the engine and/or filter.
This valve is recommended on all UGET 3 filters.

Over-temperature valve

The Over-temperature valve is available to protect the filter from excessive temperatures.
This valve starts to function when there is a sudden increase in the exhaust gas temperature. It prevents the passage of excessively high temperature gases through the filter thereby preventing damage to the filter itself .
Please note: The Over-temperature Valve must be fitted together with the Backpressure Valve.

By-pass valve

The By-Pass Valve is available to by-pass the filter if and when there is no need to purify the exhaust gases.
Three different models are available:
Manual version operated by a lever;
Semiautomatic version controlled by a 12-volt electromagnet and operated by a button;
Automatic version controlled by a 12-volt electromagnet and operated with photoelectric cells.
