Detailed Product Description

vacuum tube  solar collector

Features:
Evacuated tubes convert solar energy into thermal energy that is
transferred to copper U pipes by an aluminum fin with high solar
energy absorption and low heat radiance loss. Liquid (pure water
or glycol solution) in the U pipe heats up, and the U pipe conducts
thermal energy to the water inside the storage tank through internal
copper coils.

Uses an electrical heater to heat water during cloudy days or at night.
As the water temperature can be adjusted using an automatic controller,
user can get hot water all day long.

With a testing pressure of 12 MPa, this system has a working pressure
of 0.6 MPa.

Solar water heaters can still work even with several tubes broken.

Highly efficient insulation with integrated polyurethane foam.
