Non-pressurized Vacuum Tube Solar Collector VNC-58

DESCRIPTION
VISION VNC series non-pressurized solar collector is mostly designed for an open loop system, in which the water is heated directly inside tubes and stored in a separated tank;
The solar collectors are usually connected together in series and parallel to form large-scale heating systems, supplying hot water for hotels, factories, hospitals, schools, swimming pools, space or floor heating applications.
MAIN FEATURES
1. Most economical collector for solar water heating;
2. Wide heating applications for hot water and house;
3. Large heating capacity from 500 to 100,000 Liter;
4. Efficient direct hot water heating with big flow rate;
5. Strong adaptability to flat or slope roof installation;
6. Easy installation and connection with simple system design;
7. With anti-freezing protection it works well in subzero weather;
8. Applicable to active open loop system or thermo siphon system;
