Hot water will be output at -30℃ as usual; the high-temperature special effect tube, because the stainless steel ion in the film is resistant to high temperature and dry, the film does not age under 400℃ , Does not attenuate, does not change color.
Under the same light conditions, the heat absorption of ordinary pipes is not as high as that of the three high-level pipes, and can not even meet the bathing requirements; when the temperature is lower, the heat loss is greater, and the heat collection efficiency decreases, which affects normal use; especially when the air temperature exceeds 270℃, The film layer begins to age and fall off, the absorption rate is rapidly reduced, and the life span is greatly shortened.
