Product Details

The SOLFEX FK 500 flat plate solar thermal collector series encompasses the latest patented technologies along with industry know how.

The FK 500 black anodised frame collector is available in portrait or landscape versions and is modular in design and can be mounted in many variants including on roof parallel or raised and can also be roof integrated with an attractive anthracite flashing kit which fits any roof fabric profile.
