Introduction
Section 1
The Model 4085 electric infrared spot heater (Figure 1) is designed for use in any
application that requires clean, non-contact heat on a small target or object. Typical
applications for this heater include:
• Metal annealing
• Soldering and de-
soldering electronic
components
• Heating
thermoplastic
composites
• Localized weld
stress relief
• Brazing

Standard Features
Rapid Response
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.
Continuous Operation
The construction of these heaters, combined with air cooling, allow them to withstand
continuous high temperature operation.
Controllable Energy Output
The infrared energy emitted from these heaters can be adjusted to match the heating
requirements of a variety of applications. PCS/Research Inc. manufactures a complete
line of process control instruments and SCR power controllers to control the operation
of these heaters.
