Gold tube violet
At present is a big selling point on the market! Of course, this is closely related to its superior performance! Three purple tube slender parameters: absorption is higher than that of ordinary vacuum tube increased by 12%, emission ratio decreased by 30% - 40%, super absorbent, and less heat loss, fast temperature rise. Three Zijin pipe, super absorption, high thermal efficiency, fast heating, in the same light illumination conditions, than the ordinary pipe to more high temperature hot water; alpine tube, due to copper ion emission Bibi aluminum ion low 0.2, so heat loss rarely, in the alpine environment can still work. - 30 DEG C as usual hot water; high temperature tubes, stainless steel ion in the film due to high temperature, anti air drying, coating at 400 DEG C under the condition of aging, decay, do not change color. And in the same light illumination conditions, ordinary tube heat absorption as well as three Zijin high, even can not meet the requirements bathing; in low temperature, the greater the heat loss, heat collecting efficiency decreased, affecting the normal use; especially drying in the air more than 270 DEG C when the film began to aging, loss, absorption rate decreased rapidly, greatly shortened life expectancy. And three Zijin pipe will not appear the situation, so at present, three Zijin pipe is the substitute of the ordinary solar vacuum tube, is a market trend! From the long-term plan the purchase of solar vacuum tube or pipe is still relatively cost-effective three zijin!!
