FAQ
Q: Your company is manufacturer or trading company?
A: Yes, we are manufacturer, we have our own factory and meanwhile we cooperation with other factories in our own technology. Haiana has a 18-year background in the reverse osmosis membrane industry with independent R & D personnel and engineering, and masters the core technology of high salt water purification. HJC brands are well-known in southern India, southern Pakistan, and Syria in the Middle East and Palestine cause of worse raw water conditions in those area.
Q: How many employees does your company have?
A:our headquarters has more than ten people, 142 workers in the factory and 16 office workers. We are still a small company, and our goal is not to be the biggest, but to be stronger. In the segmented high desalination market, the product quality and service are maximized.
Q: What are the advantages of your company and products?
A: Haina 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?
A: At present, we maintain zero customer complaints on 3G and 4G products. Please note that the first item of our company's values: Do not let customers count one copper coin. If there is a quality problem, we will guarantee the replacement and be responsible for the freight on the way according to a reasonable quality problem verification process.
Q: What is your MOQ?
A: Our minimum order quantity varies from model to model. There are also differences in OEM orders. The minimum order for household membrane is 100 (two boxes), and the minimum for industrial membrane is five pieces. If there is an industrial membrane for refueling household
