EKS Solar Specification


Cutting edge solar design EKS vacuum tube is currently the most efficient solar tube worldwide it main parts are:

The Tube

The Tube: 2.5 mm borosilicate glass thickness, hail impact resistance (50kp/cm2), acid-proof, optical lens effect.



Absorber: Aluminum absorber 92% efficiency coating, aluminum nitrid sputtering, dimensions: 2000mm length, 100mm diameter.


The System
EKS-DB tubes are connected to a manifold. Every tube is floated with Glycol anti-freezing medium. The medium is premixed with distilled water to prevent corrosion and furring and it’s also eco-friendly. The system can be mounted on flat roofs, balconies, walls, nearly in every position facing due south.

EKS 600 Control unit, comes complete with 6 temperature sensors.

EKS 1600 Control unit, is a free programmable control unit, comes with 16 sensor inputs, 11 outputs, network Can-Bus, GPRS, (Cell phone) internet.
