Model: STH-150L, STH-200L, STH-300L
New Integrated Pressurized solar water heater: STH with 316L for blind tube
For our compact pressurized model STH we have special design: We use 316L material for blind tube instead of copper caecus tube, because for copper blind pipe after some period with the high temperature and high pressure, or in the water quality inferiority area, it will face corrosion and will happen blind pipe perforation phenomenon or blind pipe leakage. This new blind pipe is composed of 0.9 mm stainless steel 800 stamping with the red copper gasket.
