The excellent thermal conductivity properties of copper make it the ideal material for thermal solar collectors.

Solar energy is transferred to the circulating fluid, which is then transported further in the pipe circuit.

The high degree of cleanliness of TREFI®-SOLAR tubes makes it possible to optimise the contact with the solar panel strip. It also adapts very well to the different types of welding (laser or ultrasonic).

The delivery form LWC (Level Wound Coil) allows the acceptance of long tube lengths, which are especially necessary for continuous use in industrial series production.
