Heat and Smoke Removal Canada Blower Power Roof Ventilators are
especially designed, built and proven by independent test to meet the
need of venting hot gases and smoke in the event of fire in commercial
and industrial buildings, such as factories, warehouses, parking
garages, shopping malls and department stores.
Canada Blower Type HS PRVs reliably extract large volumes of hot gases
and smoke regardless of building configuration, location and weather
conditions. They withstand high temperatures for long periods of time.
A reliable ventilation system that can operate during a fire is both
vital and essential. It prevents smoke logging, allows people to escape
quickly, minimizes damages to property and contents and enables firemen
to attack the fire without hindrance. These power roof ventilators have
the added advantage of providing normal day to day ventilation and in
many cases can also be fitted with duct work for use in multi storey
The concept of venting smoke and heat was first outlined by Industrial
Risk Insurers (IRI). Use of powered ventilators could eliminate the
problems experienced with gravity vents. Specially designed roof
mounted exhaust fans would mechanically vent heat and smoke under
emergency fire conditions.
In addition to the reliability and effectiveness of this powered
ventilation concept, the use of HS PRVs to vent heat and smokes has
these specific advantages:
* It is not dependent on air temperature differential or wind direction
and velocity to create air movement.
* It does not rely on heat itself to activate the system. Smoke
detectros and water-flow devices also may be utilized.
* It provides for normal ventilation needs of the building as well as
for emergency use as a vital component of the fire protection system.
* There is ususally a substantial cost saving in the purchase and
installation of the dual purpose system.
* Maintenance cost for building and equipment is frequently reduced.
* The system can be effectively used in multi stories and below grade
* Reliability of operations is assured because powered ventilators are
in daily use and receive regular inspection and maintenance.
The unique Canada Blower Type HS power roof ventilators provide a
solution for emergency heat and smoke venting that is dependable under
the most extreme circumstances.
All critical components of Canada Blolwer HS PTV that exposed to the
airstream are ferrous construction to withstand high temperature
conditions. These heavy gauge materials prevent warping of fan parts
and malfunction at high temperatures. This also insures years of
trouble-free service in normal daily operation of the PRV fan.
The wind shroud is made of galvanized steel; an exterior finish coat of
epoxy can be specified. Painted parts are coated with epoxy to provide
a protective coating rated excellent for hardness, impact resistance,
adhesion and chemical resistance.
Belt and bearings are protected from the air stream by enclosing them
in a ventilated tube. Design of HS fan incorporates a heat slinger /
impeller. It isolates the fan bearings from damaging heat and draws
cooler outside air through the motor compartment and over the belt and
bearings. A spring loade, fusible link activated device automatically
opens dampers when temperature at the fan reaches 165 F. This enables
the fan to function as a gravity ventilator prior to powered operation.
A safety disconnect switch is mounted to the PRV housing. This feature
protects maintenance personnel from an accidental fan start when the
unit is being serviced.
