We got another project from another vacuum furnace machine which is one of three SCR heater regulator Controller was broken. This vacuum furnace machine has 3 heater (top, main, and bottom heater) and this issue occurs on the bottom heater.
The broken SCR was discontinued , so we replaced it with a new unit with the same specifications and interface, smaller size dimension (space saving), low power consumption, easy to find in market. Besides installing this new unit, we also set up and recalibrated this new unit.
The result was that the machine was back to optimal performance with excellent heating performance.
