Q:RTLwith around 300 workers in the factory.

RTL technical advantage lies in the high desalination technology, and the process of coating polyamide is different from its counterparts. Therefore, in the use of household membranes, according to market feedback, it can be applied to 3,000-6,000 ppm water quality. Seawater membrane can be applied in the environment of 30,000-40,000ppm, and the cost advantage is very obvious.

Q:If quality problem,what is your guarantee terms?

At present, we maintain zero customer complaints on products. Please note that the first item of our company's values: Do not let customers count one copper coin.
