Customer Reviews

The products speaks for itself, which means we have lots of customers to speak for us!

You are always my first choice for electronic make-up systems!!

by Terry Leinberger on Cooling Tower Water Level Controls

Went well. Customer seems happy with the installation on his cooling towers. Thanks Again.

The installation went very well. The controllers have been working without any issues and communicating with the BMS.

I have received zero feedback from any customers...that might not be good news. Today, in reality, it speaks volumes and it is all good.

by Dan - Fountain Supplier in Los Angeles on Fountain Water Level Controller and Sensor

Wow! I was just on a job that had one of your controls on it for the past 10 years and it looks like it has never been in the water, it was so clean!
