DIEN Water Treatment's equipment portfolio covers all water needs across various scenarios, from small commercial water purifiers for stores and whole-house water purification systems for homes, to centralized water supply equipment for factories employing hundreds of people and large-scale industrial pure water systems with capacities of tens of tons. All models support customized configurations, with pre-process optimization specifically designed for the high hardness and high suspended solids water quality in Xi'an and Shaanxi Province, reducing the risk of scaling at its source.
Customers who have visited the site understand the advantages of sourcing reverse osmosis equipment locally in Xi'an from direct manufacturers.
Firstly, quality is fully controllable throughout the entire process. Each piece of equipment has its own dedicated quality inspection record from the moment it is supplied. Core components such as RO membranes, high-pressure pumps, and piping valves are all directly sourced from top-tier brands, eliminating the use of refurbished parts or cost-cutting measures. Each piece of equipment undergoes a 72-hour pressurized and water-based simulated operation test before leaving the factory; any unit that fails the test is rejected. The failure rate of this equipment after commissioning is more than 60% lower than that of models supplied by trading companies.
Secondly, it offers maximum cost-effectiveness throughout the entire lifecycle. Without multiple layers of distributors adding to the price, customers receive direct factory prices. All consumables, including filter cartridges and membrane elements, are supplied at factory cost. Over three to five years, the overall investment saves nearly half the maintenance costs compared to buying cheaper, generic equipment.
Thirdly, customization is completely straightforward (click to learn more: DIEN's flexible customization of all models). Instead of relying on fixed configuration lists, our technicians visit your site to measure water quality and site dimensions. Based on the customer's raw water hardness, peak hourly water consumption, machine room dimensions, and precise output water specifications, we meticulously adjust the pretreatment stages, membrane element selection, and piping layout. This completely eliminates the embarrassment of installing generic models only to find they don't fit or the water quality doesn't meet standards.
Fourthly, localized after-sales service eliminates waiting time. Our factory is located in Xi'an, and our spare parts warehouse is fully stocked with all commonly used consumables and accessories. Engineers can provide on-site service within 2 hours in the city. Surveying, installation, commissioning, and maintenance are all handled by our full-time technical team, ensuring you'll never encounter situations where after-sales service is unavailable or parts take a week to arrive.
Xi'an Reverse Osmosis Equipment Manufacturer, DIEN Water Treatment – Direct Supply from Our Factory
Real Customer Case: Pure Water Project for a Precision Parts Factory in Xi'an Economic and Technological Development Zone
A company in Xi'an Economic and Technological Development Zone that processes precision automotive parts had extremely high requirements for pure water quality in the final ultrasonic cleaning process. Previously, they purchased standard models from out-of-town brand distributors, but these models frequently malfunctioned within three months: fluctuating water resistivity, rapid scaling on the RO membrane surface, 30% higher energy consumption than designed, and watermarks and white spots often remaining on the cleaned parts, directly lowering product yield. To completely resolve these water quality issues and control long-term production costs, the company directly visited DIEN's production plant and finalized a customized solution with direct factory supply on the spot.
Customized Solution: Our technical team conducted water sampling and testing at the factory for three consecutive days, recording the raw water hardness data at different times of day (morning, noon, and evening). Considering the company's core operating conditions—an average daily water consumption of 10 tons, extremely limited installation space in the workshop, and the extremely high requirements for water quality stability in the cleaning process—we tailored an integrated single-stage reverse osmosis water purification system. A two-stage fully automatic softening pretreatment unit was specially added beforehand to specifically address the common problems of high tap water hardness and easy scaling of membrane stacks in the Xi'an Economic and Technological Development Area. A highly fouling-resistant, low-pressure RO membrane was selected, improving overall desalination efficiency while reducing operating energy consumption by 22% compared to the previous equipment. Equipped with our independently developed intelligent fully automatic control system, it supports automatic flushing at different times, real-time water quality data upload, and proactive fault push warnings. The entire unit features a highly integrated one-piece rack design, occupying only half the space of traditional split-type equipment. On-site connection of water and electricity pipelines can be completed on the same day, requiring no dedicated personnel to be on duty throughout the process.
