Antifreezing Flat Panel Solar Collector, Freezing Proof Flat Panel

Sunsky solar new patent product which realize flat panel can work at -40ºC terriblly cold circumstance instead of antifreezing liquid only as working liquid .That's means if split pressure solar system adopt anti-freezing flat panel solar system ,water tank neednot equipped with cooper coil ,water can be directly circulated as heat exchange throgh water tank solar collector . Its great invention in solar thermal field ,not only greatly save solar system material & increasingly improve heating efficiency
Feature as following 
1.Safe:
Due to long term heat expansion & cold contraction corrosion fatigue system can generate liquid leaking and bursting phenomenon ,anti-freezing can avoid poison & other series consequence.
2.Improving system heat efficiency 
Anti-freezing flat panel solar collector adopt once heat exchange measure,effectively lower heat loss Compare with twice exchange system ,anti-freezing system hot temperture rising and fast increasingly .Heat efficiency is 115%
For example :10 tons project water tank if use normal flat panel solar collector No.100pcs But anti-freezing flat panel solar collector flat panel solar collector No.85pcs .15pcs normal solar collector saved ;
3.Improving system stability 
Anti-freezing can solve system failure problem caused by liquid -leaking ,crack ect.
4.Low maintance 
After sales-service is troublesome & costly ,anti-freezing solar system running year round ,low-failure rate profits installer and  customer 
5.Multi-fuction:
In winter anti-freezing flat panel collector fastly melting snow & ice pile ;In summer can be covered as installation layer on the roof to anti-ultraviolet rays .
