ABOUT US
Hangzhou Haina Environmental Protection Technology Co., Ltd, founded in 2005, is a national high-tech enterprise engaged in the research and development, manufacturing and service of reverse osmosis, nanofiltration membrane elements, and has the core technology of membrane flat sheet manufacturing. Since its establishment, it has formed deep strategic cooperation with many fortune 500 enterprises who are famous in the US, Japan and Korea, and maintained long-term close cooperative relations with domestic first-line brand companies.
The company headquarters is adjacent to the world cultural heritage "Liangzhu Ancient City Site". In 2021, the new production base had been completed. The first phase covers an area of 51 mu, with a construction area of 36,000 square meters, with an annual output of 15 million square meters of membrane flat sheet, 200,000 industrial 8040 membrane elements, and 18 million household membrane elements. After nearly 20 years of continuous innovation, Haina has developed more than 200 specifications of membrane products, including seawater desalination membrane, OC special membrane, antipollution membrane, nanofiltration membrane, high water efficiency membrane, ultra-low pressure membrane and so on. The enterprise has obtained IS09001 and 14001 system certification, the products are in accordance with NSF, RoHS, REACHSVHC and other standards, exported to many countries and regions.

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 20-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. Hynamo 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: HYNAMO have 150 workers, more than 30 R & D personnel, and we mainly use fully automated intelligent production lines
Q: What are the advantages of your company and products?
A: Hynamo 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 our 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 the household membrane is 200 pcs, and the minimum for the industrial membrane is 50 pieces. 500pcs domestic or 50 industrial ro membrane, we will provide FOB and custom service.
Q: How to pay
A: TT and L/C are acceptable and TT will be more appreciated. 30% deposit before producing, 70% balanced against the copy of B/L.
Q: What is the delivery time?
A: Usually within 7 days. Also depends on order quantities.
Q: Can the package be customized by our own logo ?
