Precision Control Systems StripIR 4185 - Manual (Page 5)

• The lamps of these heaters heat up and cool down instantly in response to power
control signals.
• They reach 90 percent of full operating temperature within three seconds of a cold
start.
• The radiant energy dissipates to ten percent five seconds after the power supply is
disconnected.
• Localized heat focuses only on the desired area without heating the rest of the
product.
• The construction of these heaters, combined with air-cooling, allows them to
withstand continuous high temperature operation.
• Non-contact heat source does not come in contact with product being heated.
• The infrared energy emitted from these heaters can be adjusted to match the heating
requirements of a variety of applications.
• Repeatable results can be achieved for consistent process outputs.
• Integrated power controllers to control the operation of the heater.
• The ceramic reflector in the heater module is self-cleaning in most applications. This
feature provides both high efficiency and low maintenance cost.
Heater Module
The absorption/emission characteristics of the ceramic reflector surfaces in the Model
4185 heater module maintain a high surface temperature. The reflector material also
serves as a re-emitter of medium wave (3 to 4 microns) infrared energy. This can be
beneficial in many processes depending on the absorptive properties of the material
being heated.
Ceramic Reflector
The ceramic reflector provides heat by re-emitting medium wave and short-wave energy.
Mounting
The back of the Model 4185 has six 10-32 NF threaded holes for mounting purposes.
Product Temperatures
The maximum work-piece temperature depends upon a number of conditions: the ability
of the work-piece to absorb radiant energy, the amount of heat loss, and the applied
voltage to the heater emitter. For continuous heating processes, the maximum work-
piece temperature should be less than 1300°F (704°C).
Heat Flux Densities
The Model 4185 can generate as much as 100 watts per linear inch (3.9 watts per mm).
Dissipated power for the heaters varies with heated length and is listed in Specifications.
Heat flux density is a product of the lamp type, applied voltage, and distance between the
lamp and the target surface.
