Optisun 245 V

High performance vertical solar thermal collector for drainback system

Data sheet

Optisun™ collectors are specially designed for gravity drained thermal solar installations. Their design optimizes costs and labour on-site, thus also reducing the total cost of the solar installation.

Optisun™ collectors' internal manifolds mean fast connection of all the collectors in series. Using the Opticonnect™ system, a series of twenty collectors can be connected in a single self-balanced row via a piping system based on the Tichelmann principle. The 3 sections of our Optifix™ range (Flat Roof, On Roof and In Roof) contains a large number of fixings designed for pitched roofs as well as flat roofs.
