What our clients have to say

“We had uncovered issues with our ABB Advant that controls our packing machine. This line worked for years without complex problems, but suddenly it stopped in the middle of a batch. As the first responsible operator, I looked at the controls and the ERR LED gave a flashing red indication. Our company has no technical department as we always solve problems ourselves, but this was outside our expertise.

We found on the internet, contacted them, and instantly got support from their Technical Support Representative. He was able to guide us as non-specialized operators to solve the problem. This online support gives us the opportunity to continue producing without a technical department or expensive contract.” – Vishal Kumar
