Custom Control Panels
Below is a success story. Customer had a 40 year old system destroyed in a fire. They had no documentation at all for the damaged system. Avatar redesigned the entire system to include: 9 PID Controls, each controlling an SCR. 28 FM Limit. 36 Heat On indicators, Amp meter, head pressure controller, 7 VFDs, Alarm buzzer and a main DC motor control.
