Description and Operation

This liquid flat plate collector is designed to absorb solar radiation. The solar radiation is converted into heat on the inner all-copper absorber.

The copper tubes attached to the absorber contain a liquid, either water or a water antifreeze mix, which transports the heat to storage, either a solar tank or a water heater. This process continues until the tank is hot for evening and morning use whenever enough sun is available.

The Gobi collector features an attractive and permanent frame that is designed for good looks as well as weather resistance in both very hot and cold regions. Because of its special absorber coating, the Gobi operates efficiently also in the winter for year-round hot water production.

Heliodyne offers the easiest mounting hardware, modular kits for for sloped roofs and tilt-up racks for flat roofs or ground installations. Other components are required for a complete system to transport the heat to storage and assure its freeze protection.

Please check the complete system packages available from The Solar Biz.

Eaton/Dole Freeze Protection Valves                                

Freeze protection bleed valve utilizes a temperature activated element which does not require any external source of power. The valve opens at 38°, or 43 1/2°F allowing the discharge of near freezing water which is replaced by warmer water. When this warmer water reaches the valve, the port closes. This cycle repeats as often as necessary. High temperature plastic body, 1/2" brass male threaded connection. 5/8"ID anti-siphon discharge port, 150 PSI maximum operating pressure.
