At RHS, we pride ourselves on the professional service and high-quality equipment that we supply to the renewable energy sector. Anaerobic digestion is one of our biggest sectors, providing only the best brands for our customers throughout Scotland and the rest of the world. Our product range has continually increased due to the ever-rising demand for gate valves, cavity pumps and associated equipment within this sector. We have the exact products to meet your unique requirements. Before any equipment should be purchased and installed, we must first understand your individual requirements.

We are proud to be working with and representing the below brands. We have specifically chosen them as they are brands in which we feel are best suited to the renewable energy sector. They have a lot to offer, and we encourage you to reach out to a member of the team to see how we can help tailor products to your requirements.

What makes us different from our competitor, is not only can we supply new, but our team of skilled engineers can strip, fault find and diagnose problems with your current pumping applications. Re-conditioning your existing pumps can sometimes be the most cost-effective way.
