The Calpak VacuumTS range is our latest innovation. It includes 160/14 VTS and 200/16 VTS which are closed circuit thermosiphonic systems with a vacuum tube collector. The vacuum tubes are equipped in the interior with Copper U-pipes and copper fins. These are ultrasonic welded, thereby providing outstanding performance and reliability. VaccuumTS is ideal for regions with cold winters and moderate sunshine as well as for users with very high hot water needs.
