WHY BURN EXPENSIVE
FUEL
TO HEAT MAKE UP AIR?
WHO NEEDS IT?
Supplying an industrial building with an adequate amount of fresh
outside air in order to overcome negative pressures created by
exhaust systems can be both difficult and expensive, especially
during the heating season. Historically, air was introduced into a
building through heated supply systems during the winter months.
Heating this fresh outside air from subfreezing temperatures to 80
or 90 degrees F. can accumulate to substantial costs during the
heating season.
All buildings have high air temperature at the ceiling level and
are often cold near the floor level. Cold air leaking into a
building lies near the floor and causes cold drafts and discomfort.
The Energy Jet System eliminates temperature
differential.
WHY IS IT NEEDED?
- To permit exhaust systems to operate properly during the
heating season.
- To prevent reverse flow through gravity vents and chimneys,
which could draw in deadly products of combustion.
- To eliminate cold drafts due to infiltration through doors,
windows, and building structure.
- To provide a healthy ventilation environment for safety and
comfort of employees.
- To improve efficient operation of heating equipment.
- To reduce heating cost due to stratification of air
temperatures within a building.
HOW DOES IT WORK?
THE ENERGY JET SYSTEM
An inexpensive method of supplying fresh outside air along with
recirculating existing in-plant air, consists of a poly fabric
flame-retardant duct supported on a cable located in the truss or a
similar high space. The fabric duct has holes along its entire
length for even distribution throughout the plant. A modulating
damper system that can be controlled automatically is used to insure
that the inside air will always be kept at a preset temperature.
This air is forced down the duct and out through the holes rapidly
mixing the cool air with the stratified heat at the ceiling. This
makes use of heat trapped near the ceiling before it is lost through
the roof.
An Energy Jet System will stabilize the air pressure
within a building and stop infiltration of outside cold air.
The cost of installing this system is a fraction of the cost of
conventional fuel fired make-up air
systems. |
