KWIKOT > SOLAR WATER HEATERS > SOLAR VACUUM TUBES

Description
Kwiksol Solar Vacuum Tubes can be used in a direct or indirect system as the potable water from the direct solar water heater or heat transfer fuild (diluted propylene glycol and water) from the indirect solar water heater passes through the aluminium manifold above the array of solar vacuum tubes and is heated by the vapour inside the vaccuum tubes which is transferred to the manifold.

The vaccum tubes consist of two glass tubes made from borosilicate glass. The outer glass is transparent allowing light rays to pass through with minimum reflection. The inner glass is coated with a special selective coating (A1-N/A1), which provides excellent radiation absorption.

The top of the two tubes are fused together and the air is extracted, which forms a vacuum. To maintain the vacuum a barium gatter (vapour) is used.

The array of solar vacuum tubes is supplied with an anodized frame and manifold.



Warranty
  • 5 Years from date of installation on the vacuum tubes providing proof of installation is furnished.

  • The warranty only applies to defects, which have arisen solely due to faulty materials and workmanship during the manufacture of the vacuum tubes.

  • Breakage or cracks to the vacuum tubes is not covered by the warranty.
