Vacuum Thermosiphonic Systems
The Calpak Vacuum 160/14 VTN and 200/16 VTN are our latest innovations. They are closed circuit thermosiphonic systems with a vacuum tube collector. The vacuum tubes are equipped in the interior with U shaped copper tubes and aluminum fins that maximize the absorbance of heat.
All Vacuum models are available as well in triple energy version (Trien models with an extra heat exchanger).
