SOLFEX evacuated-tube collector CPC INOX

SOLFEX evacuated-tube collector CPC INOX
The CPC INOX evacuated tube collectors were developed especially for solar water heating and for solar backup heating. The low pressure loss allows several modules to be connected in series. The aperture area measurements of 1.0, 2.0 and 3.0 m2 allow accurate adjustment to water and/or space heating requirements.

Solfex Energy Systems vacuum tube collectors are mass-produced products manufactured by our OEM partner and European market leader for vacuum tube collectors Ritter Solar GmbH in Baden- Württemberg-Germany. Their outstanding design, professional processing, top quality and high energy yield, as well as their excellent price/performance ratio make them stand out. High-quality, corrosion resistant and tested materials ensure smooth operation over a long useful life. The well-known indestructibility of the borosilicate glass tubes was confirmed by positive test results in the hailstone test according to DIN EN 12975-2 and the thermal shock test.

The CPC INOX evacuated tube collectors were developed especially for solar water heating and for solar backup heating. The low pressure loss allows several modules to be connected in series. The aperture area measurements of 1.0, 2.0 and 3.0 m2 allow accurate adjustment to water and/or space heating requirements. We also paid careful attention to details which are important for mounting the system: the solar system is delivered with a tentered sun protection sheet to allow commissioning the system even during maximum solar irradiation. Hand straps which can be attached to the collector frame ensure safe and easy transport onto and across the roof and can be used as transport straps for quick mounting.

To increase the efficiency of evacuated tube collectors, a highly reflective, weatherproof CPC reflector (Compound Parabolic Concentrator) is fitted behind the evacuated tubes. The special, improved geometry of the reflector ensures that direct and diffuse sunlight falls onto the absorber even when the angle of incidence is not ideal. This considerably improves the energy yield. The evacuated tube is a product with improved geometry and performance. The evacuated tubes consist of two concentric glass tubes which are sealed in a semicircular shape on one side and are joined to one another on the other side. The space between the tubes is evacuated and then hermetically sealed (evacuated insulation).

To use solar energy, the internal glass tube is coated with an environmentally friendly, highly selective layer on the outside, thus turning it into an absorber. The coating is protected in the evacuated space. The aluminium nitrite sputter coating used is characterised by extremely low emissions and excellent absorption.

 

  • Europe’s best-selling evacuated-tube collector, manufactured in Germany.
  • Specially developed for solar water heating and backup heating.
  • Suitable for on-roof, flat roof and wall-mounted installation.
  • High efficiency and minimal heat loss makes evacuated tubes idea for the UK climate.
  • A curved, specially coated reflector directs sunlight from every angle onto the tube for maximum energy yield.
  • Durable, mechanical-strength glass-to-glass seal maintains the vacuum within the tubes, eliminating heat loss.
  • High-quality, corrosion-resistant materials ensure smooth operation over a long useful life.
  • Solar Keymark approved with 20-year product warranty.
