In the water treatment equipment series, purified water equipment used in the pharmaceutical, biopharmaceutical, food and beverage, and chemical industries belongs to the top series of products. In recent years, with the strong support of the country for the medical industry and the increasing attention of the public to food safety, the demand for purified water equipment has been increasing; At the same time, due to the special requirements for production processes, raw material materials, complex processes, and bidding prices of purified water equipment, there is a large margin of space compared to other pure water equipment, which has led many pure water equipment manufacturers to compete in exploring the purified water equipment market, resulting in a mixed market. Many customers, due to their lack of understanding of the strength and qualifications of relevant manufacturers, rely solely on price to make decisions, resulting in the purchase of equipment that cannot pass GMP certification and suffering heavy losses; The author has summarized the relevant issues that should be paid attention to when purchasing purified water equipment for reference.

1、 Hardware facilities of manufacturers: Hardware facilities include a certain factory area, office space, professional personnel configuration, and after-sales service organization setup; In the overall design, assembly, and commissioning process of purified water equipment, a certain factory area is particularly important as a support. Currently, there are many manufacturers of pure water equipment in Shenzhen, and most of them are only engaged in pure trade mode. Although these manufacturers have certain advantages in price, their production capacity and after-sales service quality cannot keep up; In addition, with the transformation of value-added tax, production equipment can be used as fixed assets to offset input tax, reducing the tax burden on enterprises. Small scale trading companies cannot issue value-added tax invoices, and customers can directly eliminate such manufacturers when choosing them; The purified water equipment requires the use of 304/316 material for welding pipes, racks, water storage tanks, etc., and passivation treatment for the pipes. Therefore, when customers choose manufacturers, they should try to conduct on-site inspections.
 
2、 Software infrastructure of manufacturers: Software infrastructure is a symbol of a company's soft power. In the manufacturing of purified water equipment, cooperation with customers, supplier support, and brand reputation are particularly important. When choosing a manufacturer of purified water equipment, the manufacturer can be requested to provide past successful cases, and if necessary, the manufacturer can be asked to lead customers to the site to investigate the operation status of the equipment; For important components of purified water equipment such as reverse osmosis membranes, water pumps, filter media, etc., a strong and reputable supplier is an important condition for ensuring the good operation of the equipment. Therefore, when selecting a manufacturer, it is important to inquire whether the relevant manufacturer has established a long-term cooperative relationship with a well-known component supplier; In addition, customers can conduct targeted online research on the brand reputation of purified water equipment.

3、 Be careful not to fall into the price trap: Good value for money and value for money are what every customer expects. As the saying goes, there is no good product when it is cheap. In comparing the prices of purified water equipment, customers need to pay attention to discerning the authenticity of different manufacturers' quotes. Suppliers with artificially low prices often steal beams and replace columns in equipment manufacturing to reduce costs, which will inevitably lead to the inability of purified water equipment to pass GMP certification in the later stage of certification; Due to the fact that the installation, commissioning, and later operation of purified water equipment is a systematic project, each component has various brands, and the price difference after combination is understandable. When purchasing purified water equipment, customers should understand the composition of the main components in advance and consult relevant information to have a clear understanding.
