Vacuum Tube (Non Pressure-bearable) Systems

♦ –  Non Pressure-bearable System suited for Potable Water

♦ –  Reaches temperatures of 90° - 95°C

VTN Series

The VTN Series is an open-circuit solar water heater that uses the highly efficient Evacuated Tube technology and performs equally well in areas of low and areas of high solar energy (such as the central highlands). The system is suited to application where water lines have low-pressure (< 0.5bars). They can be installed on most roof/slabs, and is a reliable product designed to last a lifetime.

The evacuated tubes capture a high degree of solar irradiation by the selective coated inner surface contained within a glass vacuum, heating the water directly in the tubes. By the principle known as the Solar-siphon Effect the heated water is transfered to the storage tank ready for your use - hot water free from the sun!
