What our customers say

Thanks to Amy and Sam for their assistance last week. It's always really appreciated to know Quantum are at the end of a phone when we need you all to get us back up and running.

Ken Barker, June 2020

Just wanted to say a big thank you for your efforts on Saturday evening when I contacted the out of hours team to get us out of the mire. We had an event which lead to the failure and subsequent loss of 2 inverters; this stopped us from brewing our products. Within 20 minutes I was being told that a solution was being worked up to get us up and running again. A truly outstanding service! Once again, we thank you for a full and proper service. Quantum Controls were the only 24hr service to respond to our call. Cheers!
