INSTALLING THE COMPRESSOR UNIT.
2.
Mounting of Compressor Unit considering Ventilation. (continued)
2.2.
Enclosed Mounting.
It is important that discussion occurs between the manufacturer and the person installing the unit
when it is to be placed in an enclosed area. Ventilation is one of the most important things to consider
when looking at the installation of a compressor/diesel engine driven unit in an enclosed area. It is
important that the air intake to the compressor and the engine exhaust are located outside of the
enclosed space. The unit generates considerable amount of heat when running. Proper ventilation is
vital for proper operation and to avoid damage to components. Ensure there is a minimum of 10" (250
mm) clearance between cooler grills on SMAC and any other components mounted on the vehicle. It
is strongly recommended that the installation is tested in the event that the unit is installed in an area
considered to be enclosed mounting. The following is a method suggested for testing.
1.
It is best to test the installation at the hottest expected ambient temperature.
2.
Setup and run the system at 120 PSI. This can be done by installing a ball valve on the air
outlet pipe and adjusting the opening of the valve so that the compressor is running
continuously at 120 PSI.
3.
Record the engine, compressor and current ambient temperature for future reference.
4.
Run the system at full load for at least one hour or until the temperature stabilizes.
Temperature stabilizing means there is no rise in temperature for 15 minutes when the
compressor is running at the rated load.
5.
Record the engine and compressor temperatures every 10 minutes.
6.
If the system over-temps, the ventilation is not sufficient, review the installation, make
changes as needed, and repeat the test.
3.
Engine Exhaust consideration when installing Diesel Engine Driven Compressor Unit
In the event that the exhaust system needs to be ducted away from the engine assembly, the
following are a minimum that should be considered -
The exhaust pipe needs to be adequate for the engine.
There needs to be a flexible joint at the point where the extension is connected to the exhaust
system of the Diesel Engine Driven Compressor Unit.
Ensure the exhaust pipe has suitable clearance and does not come in contact with anything.
Ensure that if the exhaust system has a method to prevent water from entering the exhaust
system.
Ensure exhaust from the diesel engine is routed in a way to prevent recirculation back into the
unit.
