1、Product overview

The solar collector split with water tank, open tank with unpressurized water. Pressured water with coil tube heat exchange system, it needs 2-5 bar pressure for supplying water. Medium of heat collector circulate is water, emptying the heat collector and tube's water for anti-freezing. It needs the vertical distance between heat collector and water tank less than 5 meters.

8 、Product features

  • High efficiency of blue film flat plate solar collector imported from Germany. Best stability and prevent system from anti-overheating.
  • Flow rate can be monitored by flowmeter.
  • The shape and capacity of solar water tank can be customized.
  • Adopt paraffins thermal insulation technology on the top of water tank.
  • Fresh water every time, use heat exchange system. It doesn't have water quality problem for long time leaving unused.
  • It is easy to maintain, top cap of water tank with flange connect.
  • Pressure water with unpressurized water tank, easy to adjust pressure and temperature, and easy to combine with other heating producers ( electric / gas water heater/ boiler ).
  • Water tube with cyclic system to keep hot water when open the tap.
  • Continuous and stability hot water, it has 2-5℃ range of thermal waste.
  • Adopt galvanize tube for whole circulation tube and SOLA special thermal insulation tube.
  • Low maintain cost, it needs not replenish solar liquid.
  • Adopt natural emptying of the freezing measures as the frozen area, high efficiency and tability.
  • Adopt the shortest tube for the system design to avoid heat waste on heat collector pipe.
  • The vertical distance between heat collector and water tank should be less than 5 meters to low the energy consumption.
