“I highly recommend DSU Fridge Seals, they have an extensive range of seals available on their easy to use website. The service is extremely helpful when it comes to selecting the right profile and offering assistance by telephone, email and sometimes in person. Delivery turn around is quick and efficient.”

April Burrows Altiga refrigeration

“I have dealt with DSU for many years, their knowledge & range of profiles is extensive. The UK back up and support is excellent and delivery is quick. On some occasions we needed to ship items ahead of the normal lead times and they took care of this for us. I like the fact that on many of the profiles there are options for having them made in different material choices, such as TPE. We consider which material would best suit the customers site application which is vital in commercial kitchens where heavy use is a factor. You do pay slightly more which I have no problem with as the gaskets in the TPE range will last a lot longer than the standard materials. I also buy standard PVC which are perfect for what I call “my low use customers”. DSU are a key supplier to my business and I would have no hesitation in recommending their vast range of products and services.”
