Catalysts

Exhaust gases produced by internal combustion enzymes employing unleaded petrol, diesel and gas, contain unburned hydrocarbons, carbon monoxide and aldehydes.

OSCA V3NA

industrial catalysts

Exhaust gases produced by internal combustion engines running on unleaded petrol, diesel or gas, contain unburned hydrocarbons, carbon monoxide and aldehydes. When these fumes exit the combustion chamber, they are released into the atmosphere and add significantly atmospheric pollution.
These gases are responsible for environmental degradation and they are highly dangerous for people causing serious illnesses to the respiratory organs.
These effects become much more severe when the machines work in closed or partly enclosed environments (e.g. mines, tunnels, warehouses, etc.).
To resolve these problems, the OSCA catalyst utilizes the chemical conversion performed by catalysis and transforms unburned hydrocarbons (HC), carbon monoxide (CO) and the aldehydes into non-toxic carbon dioxide and water, as illustrated by the diagram below.

Due to its small size the OSCA catalytic converter is easily fitted on power generators, earth movers bulldozers, forklift trucks, off-road vehicle and any similar machinery.
The use of the catalyst coupled with the application of a particulate filter or FAP offers maximum emission control.


METALLIC HONEYCOMB
The OSCA catalyst has a metallic honeycomb construction on to which optimized amounts of noble metals are added (platinum, palladium and rhodium). There are several advantages on using metallic honeycomb structure as opposed to a ceramic structure:
• Reduced back pressure since the metallic honeycomb walls are thinner (0.04mm) as compared to the ceramic version (0.15mm)
• Smaller overall size since the reduced internal structure facilitates the use of a reduced catalytic mass
• In contrast to ceramic honeycomb, metallic honeycomb is far more robust and does not suffer from irreparable fractures or breaks created by impact
• Metallic honeycomb reaches higher temperatures more quickly than ceramic due to the higher conductivity of metal. This provides high efficiency even in the event of intermittent use.

EFFICIENCY
The OSCA catalyst should be installed as close as possible to the exhaust manifold where the exhaust temperature is highest.

The catalyst becomes operational at 180/200°C and at 250°C, 90% elimination of pollutants is achieved.
In order to reach the necessary temperature, insulation of the OSCA catalyst (with ceramic wool, fibre glass, etc.) is recommended.

The OSCA purifier has been tested by the Italian Experimental Laboratory of Combustible products in Milan; the efficiency is shown in the graphs below.

INSTALLATION
It is essential that the OSCA V3NA catalytic converter is installed as close as possible to the exhaust manifold since the high temperature is crucial for high catalytic efficiency.
Install the catalyst in the exhaust line. There is no particular direction for the exhaust flow through the purifier.
As the catalyst doesn’t act as a silencer, the original silencer system is left in place.

Fitting accessories are provided with the catalyst.
In order to meet all possible types of installation, Bersy produces four different models: standard, with flanges, flanged type and lateral illustrated below.

LIFE
Since the OSCA catalyst facilitates a catalytic reaction, the life of the catalyst is theoretically unlimited.

However, since operating conditions are not ideal; poorly tuned engines, engine vibration and the abrasive action of fumes on the honeycomb, the life of the catalyst is reduced, therefore the actual life of the OSCA V3NA is approximately 12,000 hours.




MAINTENANCE
Due to high temperature, the OSCA V3NA catalyst does not need planned maintenance.

When the catalyst is fitted to a LPG or petrol engine, no maintenance is required; when the catalyst is fitted to a diesel engine, cleaning is suggested every 500 hours of use, as follows:

• Remove the catalyst and soak in hot soapy water for 5 hours
• Dry thoroughly (with the aid of compressed air, if necessary)
• Reassemble the catalyst on the machine

In order to choose the correct OSCA model, proceed as follows:

1. For 4 stroke engines read directly from the table.
2. For turbo engines multiply the appropriate cubic capacity by 1,4 before reading the table.
3. For 2 stroke engines multiply the appropriate cubic capacity by 2 before reading the table.
