FAQ
Q: Your company is manufacturer or trading company?
A: Yes, we are manufacturer, we have our own factory and meanwhile we cooperate 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 mastered the core technology of high salt water purification.
Q: How many employees does your company have?
A: Hynamo headquarters has more than ten people, 200 workers in the factory and 32 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, product quality and service are maximized.
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 3,000-4,000 ppm water quality. Seawater membranes can be applied in an environment of 30,000-40,000ppm, and the cost advantage is very obvious.
Q: if quality problem, what are your guarantee terms?
A: At present, we maintain zero customer complaints about 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 100 (two boxes), and the minimum for the industrial membrane is five pieces. If there is an industrial membrane for refueling household
Q: How to pay?
A: TT and L/C are acceptable and TT will be more appreciated. 30% deposit before production, 70% balance against the copy of B/L.
Q: What is the delivery time?
A: Usually within 15 days. Also depends on order quantities.
Q: Can the package be customized with our own logo?
A: Yes, the package can be customized with your logo, but the MOQ will be higher which we can discuss as per the specific orders.
Q: How to install it after the products arriving the destination?
A: We will provide detailed illustrations to you. And we can also provide a guide to your workers on how to use it and how to maintain it.
