Equipment

A complete solar plant needs, next to the big components like collectors and storage tanks, the right equipment and accessories. We separate our equipment between the Heat Pipe equipment, Direct Flow equipment and the universal ones. Our assortment ranges from small screws to the bigger fixing set. Something got lost or damaged? No problem, we would like to help you individually and personally. We will answer all your questions about our solar plants and tube collectors. We are here for you at any time!

Universal equipment

Here you can find all the universal equipment that we offer at AKOTEC. The equipment fits in every one of our solar plants, no difference between the Heat Pipe or Direct Flow systems. You are missing a specific equipment piece, but don’t want to exchange the whole solar plant or repair it? No problem, we ship our equipment individually as needed.
