Description

The SUNDA’S SEIDO Evacuated Tubes are engineered for optimal thermal efficiency, utilizing advanced heat pipe technology that dramatically enhances heat transfer rates. Each tube is a closed system integrating a two-meter copper tubing assembly, featuring an evaporator section, capillary wick structure, and condenser section filled with a small amount of vaporizable fluid. The innovative evaporating-condensing cycle efficiently captures solar heat through its tightly bonded evaporator section, converting liquid into steam which then ascends to the condenser. Here, the steam is condensed by circulating water, effectively transferring latent heat energy to the process water. This continuous cycle maintains consistent heating in the solar loop, making it a reliable choice for solar energy applications.

Advantages of the Technology:
– High heat transmission rate
– Fast start-up capability
– One-way heat conduction
– Homogeneous heat distribution on the condenser surface
