Infrared
Oven designed to
cure or dry water based or high solid
stains, sealers, and top-coats. High
velocity flash off sections enhance the
curing process. Engineered to fit over
your existing conveyor or built as an
integral part of your new finishing
system, drying tunnels are economical,
reliable, easy to install.
Long-wave, medium-and short-wave
infrared energy may all be used in
heating ,drying and curing processes,
with the most efficient type being
determined by the actual process
requirements. Long- wavelength infrared
emits energy between 4.0 and 6.0
microns, with energy densities of 5 to
15 watts per square inch.
Medium-wavelength infrared emits energy
between 2.4 and 4.0 microns, with energy
between 2.4 and 4.0 microns, with energy
densities of 15 to 60 watts per square
inch. Short-wavelength infrared, also
known as High-Intensity infrared, emits
energy between 1.0 and 1.2 microns with
energy densities between 100 and 200
watts per square inch.
By studying the properties of the
material to be used, Casso-Solar selects
the infrared heater that is best applied
to the process. Considerations for the
selection include performance, space
availability for the equipment,
reliability, safety, and ease of use.
Choosing the wrong infrared system may
result in wasted production floor space,
excessive operating costs and
inconsistent quality. Often replacement
systems provide short payback periods
based on electrical power savings alone.
Infrared
Oven provides the heat, the cure, the
bond and the catalyst for a wide variety
of industrial processes. Infra red
oven’s most important role however is
the one in which it first found
widespread use: the curing of liquid
coating. Whether solvent-based,
waterborne or non-reduced, infrared is
the curing technology of choice among
manufacturers of metal, plastic and
composite parts. Infrared ovens consist
of infrared lamps that put maximum
energy in the area where materials are
placed. Infra red ovens are designed for
high energy efficiency to save power and
fuel cost. Infra red ovens allow
combining with ambient air with the hot
air for increased drying speed.
Advantages of Infrared Oven:
• Production speed
• Space considerations
• Presentation of parts
• Control
• Capital costs and maintenance
• The infrared ovens are very
environmentally friendly emitting no
regulated pollutant gases.
GAS FIRED INFRARED OVEN:
A gas-fired
oven is disclosed wherein heated air is
delivered to an oven's interior from a
gas burner located outside the oven in a
way to enhance the convection heating
properties and capacity of the oven.
This is accomplished by means of a
conduit which receives air heated by the
external gas burner and internally
discharges this heated air into the
return air path of a blower used to
recirculate hot air within the oven. The
internal discharge end of the conduit is
located adjacent to the blower's return
air path so that the conduit does not
obstruct the recirculating air. The
external gas burner may be either an
atmospheric burner or a power burner.
Its gas burner head is axially aligned
with the
conduit's exterior inlet end and spaced
a short distance from this inlet. The
spacing between the burner head and the
conduit inlet controls the dilution air
which is required to regulate the
temperature of the hot air according to
the oven's function such as heating
food. Gas-fired ovens are used in
diverse industrial applications and can
be used as Foundry core ovens, Powder
coating ovens, Paint baking, Burnout,
Drying etc. The air circulation is done
with the help of blower from bottom to
top that ensures uniform temperature in
the chamber.
ELECTRIC
INFRARED
OVENS:
Electric
ovens use electric infrared elements, or
sources. Electric infrared sources are
heated by current flowing through a
resistance heating element. The element
and the material surrounding the element
are heated to an incandescent
temperature.
All well designed electric ovens exhibit
the following characteristics:
• Vertical and horizontal zoning. To
provide an effective, flexible, and
efficient application of electric
infrared heating to a specific process.
• Precise layout and distribution of
elements. To incorporate shape factors,
overcome an edge effect, and provide
greater flexibility.
• Insulated reflective panels to
reradiate heat. To provide reradiation,
even when panels may be dirty.
• Insulated element wiring to provide
additional life. To extend significantly
the life of the infrared elements.
• Non-contact temperature sensors for
control. To provide the optimum in
temperature control.
• Rigid, non-vibrating structure. To
lengthen the life of the elements.
• Custom control. To meet the specific
needs of the process and the operators.
DRYING
INFRARED
OVENS:
Drying
Ovens, also referred to as Dryers, are
typically used for the removal of
moisture from water-based coatings and
adhesives. Drying Ovens are also used
for removing water from the surface or
interior of certain products or
substrates. Infratrol Drying Ovens are
designed and built to your specific
requirements for part size, production
rate and thermal characteristics.
WATER DRY-OFF
INFRARED OVEN:
Water
Dry-Off oven completely removes the
residue water, film the parts after they
leave the cleaning machine. This is
especially important for applications
where powder paints or solvent based
paints are applied shortly after the
parts leave the dry off. The dry off can
be constructed as a convection oven or
dehumidification dryer.
CAMEL BACK
INFRARED
OVEN:
Camel-back ovens are an extremely
efficient design and especially useful
for powder coating systems. The
description is applied to an elevated
oven that permits loads to enter and
leave through openings in the oven
floor. The Camel Back design allows
multi colours to be cured simultaneously
without the fear of cross contamination.
This gives more capacity which means
faster turnaround. The design of the
oven also allows for heavier and bulkier
items than the on line oven above. This
oven is monitored to give accurate
back-tracking on the time and
temperature of any particular job. Main
advantage, especially for powder
coatings is that this entry arrangement
does not require a powered airseal and
therefore does not result in powder
disturbance.
Other Advantages:
• Space saving.
• Manufactured to your specific needs
• Designed to minimize heat loss
• Individual panels easy to move.
• High temperature circulation fans.
