Refuse the ”one price for universal sets of machines" routine: Many middlemen directly quote a fixed price for foreign general-purpose models, regardless of your local well water hardness and sediment content. This kind of equipment will quickly scale and block the film after 3 months of operation under high-hardness conditions. The hidden cost of subsequent film replacement and pickling far exceeds the original purchase price difference.
Verify the hard certificate of ”local entity production": Don't just listen to the other party verbally say that you are the source manufacturer. When inquiring, you directly ask to see the real-time production workshop photos and the on-site completion photos of the same tonnage project in Xi'an in the past 3 months. Only those who can directly invite you to see the equipment in production are the real local manufacturers, avoiding shell traders who are purely OEM.

Clarify the list of “water quality adaptation configurations”: The hardness of raw water in the Guanzhong area of Xi'an is generally in the range of 300-500mg/L. The compliance configuration must be equipped with an independent softening unit +5 micron precision security filter in front of the reverse osmosis host, and only a low-cost solution for simple PP cotton pretreatment can not be adapted to the local water quality at all, and the problem of water production will be reduced in half a year.
Lock in the "localized after-sales response time limit": When inquiring, you must clearly mark in the quotation that the time limit for failure to come to the door within the Xi'an bypass area is ≤12 hours, and the area in the suburbs of Shaanxi is ≤24 hours. After-sales of foreign brands need to wait for engineers from different places to send express parts, and it takes a week to come to the door, which directly slows down the pace of enterprise production.
Avoid the trap of ”bundling consumables at low prices": Some merchants keep the price of equipment extremely low, but later increase the price of special scale inhibitors and filter consumables by more than 3 times, and the long-term operation and maintenance costs are directly doubled.Regular local manufacturers will separately list the public market price of consumables, and will not rely on the equipment to drain at a low price and harvest users on subsequent consumables.
