Distinction of product
- First : No leakage occurs even in 50,000 times of repetition test of heating(200℃) & cooling(-30℃).
- Second : Stainless steel 316L that is corrosion resistant against Anti freezing solution (Calcium chloride, Sodium chloride) is used to prevent corrosion.
- Third : Helical type corrugation tube does not generate any vibration or noise of the tube.
- Forth : Assembly is more convenient than Copper tube(no welding work needed) and the price is about 40% cheaper than Copper tube.
- Fifth : Thickness of Copper tube, heat-exchange coil inside of heat-storage tank, is 0.8mm while stainless steel corrugation tube thickness is 0.3mm. Heat-exchange surface of stainless steel corrugation tube is about 40% larger than Copper tube, which lead 33% reduction of heat-exchange coil length
In case of steel thermal thank, both ends of heat exchanger coil are brazing-welded to male or female nipple which is to be connected by welding to the tank. In case of synthetic resin tank (plastic tank), both ends of heat exchanger coil are brazingwelded to male or female nipple which is to be connected by screw fitting ststem to the tank. (Regarding these connecting methods, please refer to model 006).
And please refer to model 003 & 006 for solar thermal system and helical corrugated tube’s sizes and fittings.
