Solar evacuated tube collector SUNSYSTEM VTC

PRODUCT FEATURES:

• Evacuated tubes of heat-tempered borosilicate glass.
• Selective coating for efficient sunlight absorption.
• Heat transfer plates resistant to high temperatures of stagnation.
• Copper heat-carrier tubes type Heat PipeTU 1. The pipe system is manufactured with a minimum number of welds for perfect air-tightness and reduced deposits accumulation possibility.
• Both outlets of Manifold pipe can be connected as heat-carrier input or output in any direction.

Dry evacuated tube solar collectors made by Heat Pipe technology are characterized by their high efficiency: improved heat-absorbing capacity of collector, low heat losses and stable performance in harsh climate conditions. Temperature sensor can be mounted left or right, depending on the position of the heat-carrier outlet.
The Heat Pipe itself is a compound of two concentric glass tubes with evacuated space between them. The inner tube surface is covered with selective coating allowing maximum absorption of sunlight and high performance efficiency. Through the center of the heat pipe runs a hollow copper tube, inside which begins the process of evaporation of non-toxic fluid that transfers the heat to the tube top and then releases it to the collector pipe to heat up the heat-carrier inside. Then the process repeats over and over again.
