What our Customers have to say: 

We are new to Milk Pasteurising and would highly recommend Unison as a part of your dairy team. The pasteurising unit is fantastic, highly efficient and easy to use. Excellent and trustworthy customer service and availability even during these tough pandemic restrictions. Nothing was too much trouble and we really appreciate all of the support.

Lindsey Richards

Owner, Mount Farm

Arrabawn Dairies have been using Unison to service our Pasteurisers, Homogenisers and storage tanks for the past 14 years. Unison does an excellent job, they are always punctual, professional and offer the most competitive rates in the industry. They provide 24hr support and can be onsite within an hour – this is critical to us, and why we use them, they are extremely dependent.

John Fay

Maintenance Manager, Arrabawn Dairies
On purchasing the Cheese Milk Pasteuriser, I found it to be very user-friendly. The touch screen simplifies its use for operators. Prior and aftersales contact I have had with Unison and their staff has always been handled in a professional and courteous manner. I would have no hesitation in recommending Unison Process Solutions for any future similar installations.
