Canada Blower
has developed reliable and efficient air
make-up units for industrial building ventilation. In industrial plants
where
there is a high density of employees and many manual operations
involved, an
improvement in the environment can produce substantial benefits in
terms of
increased production, reduced errors, and a decline in complaints and
absenteeism among employees.
Direct
Gas-Fired Air Heating Systems are a class of
equipment utilized primarily in industrial and commercial environments
to
provide for worker comfort. To a lesser extent, these systems are used
to
condition air for process and finishing applications such as material
drying
and paint curing.
These systems
have gained widespread use due to the fact
that they are inexpensive to build, maintain, and operate compared to
other
furnace types of comparable heating capacity.
The key
advantages are simplicity and efficiency. No heat
exchanger is required. This eliminates component installation and
maintenance
costs. With no heat transfer losses, the unit is nearly 100% efficient.
The primary
disadvantage is the introduction of waste
products into the airstream. For this
reason, both
ANSI Z83.4/CSA3.7 and ANSI Z83.18 standards
state: “Heaters covered by this standard are intended for use in
industrial and
commercial applications.” ANSI Z83.18 states further that: “Heaters
covered by
this standard are not intended for use in any area containing sleeping
quarters." Carbon Monoxide and Nitrogen Dioxide are the primary
pollutants. These are limited to no more than 5.0 PPM for CO and 0.5
PPM NOX, a
fraction of OSHA allowable Permissible Exposure Limits(PEL’s).
A Direct
Gas-Fired Air Heating System may be used in an
industrial or commercial application for any or all of the following
purposes:
* Make-Up Air
Heating – Air is introduced to a building to
replace air being exhausted.
* Space Heating
– A unit provides primary or supplementary
heating to a building space.
* Space
Pressure Control – Building or Room Pressurization
is held within a range.
