In the world of electric heaters, one of the most critical elements to consider is the control. Depending on the specific application, a certain level of control is not only desired but often required. In order to achieve adequate results, operators need to be confident that the process is reaching a specific temperature at the proper time on a consistent basis. 

Industrial manufacturers and plant engineers need a reliable, flexible and cost-effective way to control power to electric heaters used in their plant’s manufacturing processes. Of all the controls available, silicon-controlled rectifiers (SCRs) best meet those needs. The precise control offered by SCRs extends heater life, reduces maintenance costs and improves product quality.

The EPack compact SCR power controller is designed to be a replacement for aging contactors, solid state relays and silicon control rectifiers.

Heating derived from electrical sources is used extensively in industrial processes for thousands of widely varying applications.
