Heatrex can provide a control system for any electric heating application. We have built thousands of heater control panels. Our experienced engineering staff can design control systems ranging from ON/OFF logic to fully proportional SCR, multiple channel and ramp/soak control with computer interface capability.
Heatrex offers two standard control panel designs: Fully proportional SCR control and ON/OFF contactor control. All components are factory mounted and wired in compliance with the National Electrical Code.
This contactor-based system with ON/OFF process temperature control is recommended for less demanding applications. Systems with two of more heating stages utilize a Heatrex controls electronic sequencer (step controller), driven by a proportional output temperature controller to minimize the amount of load cycling while providing good outlet temperature control.
