Selco Success Story: Custom Electronic Controller for Precision Tank Heater

Selco custom electronic controller for precision tank heater

Selco was approached by a customer needing an electronic controller to replace a competitor product that would be used in a precision tank heater.

The requirement was an electronic controller kit that included a proportional heating electronic control board assembly and a potentiometer assembly.

Selco was able to modify its custom water heater control by removing the touch control and LED’s, accommodating a potentiometer and adding the quick connect arrangement the customer needed.
