- Procurement Manager, OEM - Insulation Blowing Machines
I would like to commend your Engineering Manager for following up on a customer's feedback related to one of your products. He communicated with me in a timely manner. He also went a step further, suggesting a better solution for our customer's application. It was a real pleasure to interact with such a professional!

- Service Team Leader - National Industrial Supply Company
I sourced Macromatic's PMDU Phase Monitor Relays on the internet as an alternative to another brand I could not get for 12-weeks. I reviewed product specs and met with my staff who were okay with the PMDU. I then called three panel builders and each one said that Macromatic PMDU was a good choice. The PMDU is now our standard.
