Copper Coil Heat Exchanger Specifications
Material	12mm x1.0mm copper pipe
Surface Area	1.13m2 for 30 tube water heater
Testing Pressure	9 bar
Net Weight	15kg for 30 tube water heater

Working Principle:
Heat exchanger inside the tank which provides more than 1.5m2
of heat transfer area. When water flows through the coil, it
absorbs heat from the water inside the solar collector tank. The
solar collector tank is therefore a thermal store.
Specifications:
◆ Tank material: Interior SUS 304-2B
