GFX4-IR: the new frontier of IR heating control

February 04, 2011


Gefran launches the GFX4-IR, its advanced power controller with hardware and software functions specifically for IR (infrared) heating elements of any wavelength.

IR lamp heating technologies are being applied more and more often in industry, and provide concrete advantages over traditional heating devices.

They are used in a wide variety of industrial processes, from producing PET bottles to cooking foods in ovens, from finishing furniture to heat treating silicon wafers for photovoltaic panels. This applicative flexibility is typical of contactless technologies, in which the product is not (or must not be) in contact with the heating element.

The use of IR lamps has many advantages, including better process control and reduced dissipation of electrical energy, thanks to a highly sophisticated control technology that directs heat to the required point of the product/process.

GFX4-IR, with zero crossing mode, manages and balances individual half waves and controls radiation stability to eliminate flickering. IR lamps, especially in the short wave range, have a very long reaction time and non-linear behaviour between cold lamp and lamp at working temperature. If the heating elements are not correctly controlled, there is risk of flickering, which generates non-stable temperature on the product and shortens the life of the element.

In addition, GFX4-IR does not generate EMC noise when used in zero crossing mode, eliminating the need to install expensive filters in panels.

Soft Start functions, control of peak and RMS current, phase angle trigger functions, feedback functions in voltage, current and power, satisfy the multiple demands of controlled processes.

GFX4-IR is an all-in-one solution with 4 controllers , 4 SCRs with heat sink, 4 current transformers, 4 voltage transformers, 4 fuses and 4 fuse holders: an unbeatable mix that offers enormous benefits in terms of reduced space and wiring.

Optional fieldbuses can be used to interface with Profibus DP, Devicenet, CANopen, Modbus TCP, Ethernet IP and EtherCAT communication devices.
