 Our
expert technicians are specially trained in the evaluation of existing ventilation and process equipment
to determine what changes are needed in order to maximize filtration
efficiency, lower maintenance, and extend equipment life. This
is an engineering design evaluation that focuses on your ventilation
volumes, hooding, ductwork, collector, and fan. Budgetary investment
values on recommended equipment may be included depending on the
process and the suggested solutions. The full audit consists of
an analysis of the following:
Ventilation
Requirements
As your
ventilation system changes to accommodate increased production,
ventilation needs, or process changes, more airflow is required.
If your system has not changed, but airflows are not at design performance
levels, having a system audit performed will help to determine why
this is happening and if a fan change is required.
Dust Collector
Capacity
We analyse your air-to-cloth ratio to determine the operating
limits of the dust collector as compared to industry standards.
Ductwork
Existing
ductwork diameters from each individual vent point are measured
and cross-sectional areas are calculated to ensure the sizes are
correct for the required air volumes.
Hoods and
Recommended Volumes
The hooding design at pickup points should provide ventilation of
the dust point, while minimizing the amount of product introduced
into the dust collection system. Improperly designed hoods tend
to increase the grain loading beyond what the collector was originally
designed to handle. The Industrial Ventilation Guide recommends
standard design practices for hood design and volumetric requirements
for transfer points.
Based on these
practices, specific minimum and maximum volumes are calculated and
compared to required volumes. A written recommendation is then
made regarding the system's potential to perform as installed.
