Non-pressure Solar Collector
Non-pressure solar collector working principle:
Working principle it’s similar to non-pressure solar water heater, non-pressure solar collector it’s not a storage water tank, just a manifold. The selective coating absorb the solar energy and converts it into thermal energy for heating water. This type solar collector always used for large scale commercial solar water heating project, hot water between tank and solar collector always circulated by a circulation pump.
Non-pressure solar collector characteristic:
● The round absorber surface of vacuum tubes passively track the sun throughout the day.
● Available in 20, 25, 30, 50 and 60 tubes model, flexible combination, meeting customers' different requirement.
● Environmentally friendly, small investment with big payback.
● Good for large scale solar water heating system installation.
● Low maintenance.
