CHOOSE THE RIGHT POWER CONTROLLER TO MAXIMIZE HEATER PERFORMANCE AND LIFETIME
There are four common power controller types; electromechanical relays, mercury displacement relays, solid state relays and silicon controlled rectifiers (SCR's).
Choosing the right device to switch power to your heater can make all the difference in your process control as well as your heater lifetime.
See the attached table comparing these different devices and choose correctly the next time you need to make a purchase.
