Solar vacuum tube


Vacuum solar system

The specialsolar vacuum tube T12-CPCis the revolution for forced circulation system with auxiliary heating.

The accurate design achieves high performance even in winter with low outdoor temperatures and low light.

Solar thermal collectors T12-CPC are ideal for domestic water heating, but are also suitable as a supplement to the heating of rooms.

The modules are small, lightweight and modular so simple to install.
Each module consists of six tubes only 55 mm thick and its total weight is 16,4 Kg.

vacuum operation

The principle of operation of the solar panel vacuum tube is equal to that of a normal thermos. The tubes are formed from double glazing, the gap between the two glass retains heat even when outside temperatures are very low.

The mirror reflective CPC place under the pipes allows to exploit solar radiation in an optimal way, since it reflects the sun's rays from multiple angles and conveys them in evacuated tubes with very low heat losses.

The cylindrical tubes also capture the slanting rays (which are usually lost with flat plate collectors) thus providing a high yield, even in the afternoon and facing unfavorable.

Reflector sunlight

They capture the sun's rays slanting

Under the vacuum tube is placed in a special mirror parabolic reflectors (CPC) that embraces the manifold.

This sensor light can also capture the sun's rays reflected on the oblique vacuum tube, while maintaining the original heat and minimizing heat losses.

The riflettitore is made with special materials capable of providing excellent yields of the diffused light.

By the construction of the reflector related to those of the vacuum tube, the solar thermal system increases exponentially performance even whenthe sky is overcast and low light.
