Jiajie Bianxiao answers how to choose a good ultrapure water equipment from the customer's point of view:
1, look at the border first, the weld is smooth and there is no unevenness. The whole gives a heavy feeling.
2, look at the pipe connection, pipe connection horizontal flat vertical, see whether the surface finish of pipe fittings is uniform.
3. Are the high-pressure pump and raw water booster pump the products of regular manufacturers?
4. The tank in the pretreatment part is definitely heavy, and some small manufacturers choose thin tanks to save costs, which is prone to problems.
5. Is the membrane a refurbished second-hand membrane? In fact, there are many kinds of membranes. For example, dry film is cheaper than wet film, and refurbished carbon for activated carbon can't absorb chloride ions at all. Many small manufacturers cut corners to compete at low prices.
Is after-sales service in place?
1. Whether to install and debug at home.
2. Can on-site operators be trained?
3. The warranty period is generally one year, and the quality problems will be repaired free of charge within one year. If you can do the above, you can usually choose a good ultra-pure water equipment.
