Description :
these systems pump heat-transfer fluids (usually a glycol-water antifreeze mixture)through the solar water heater.Heat exchangers transfer the heat from the fluid to the water that is stored in tanks.Double-walled heat exchangers or twin coil solar tanks prevent contamination of household water.Some standards require double walls when the heat-transfer fluid is anything other than household water.Closed-loop glycol systems are popular in areas subject to extended subzero temperatures because they offer good freeze protection.CEshanghai230039004000packing aloneChina1
