Our Service

Jianyun Zhishui (Qingdao) Industrial Technology Co., Ltd., a brand of VLLRO, believes that excellent products must be accompanied by impeccable service. We have built a full-process service system that runs through pre-sales, sales, and after-sales, ensuring that you can experience professional, efficient, and worry-free cooperation in every link from consultation to delivery to maintenance.

We have a professional foreign trade service team, team members cover, sales, engineers, after-sales service personnel and so on.

Our international sales team is not only fluent in multiple Chinese languages, but also well-versed in international business practices in the water treatment industry. They are your bridge to efficient communication, responding promptly to your inquiries, providing detailed product catalogs, quotations, and technical specifications, and handling various business matters, ensuring smooth and error-free communication.

Our team of expert engineers is at the heart of our services. Our experienced team of water treatment engineers and mechanical engineers can provide you with in-depth technical advice and solution design. They can tailor the most economical and efficient water treatment process (e.g., multi-media filtration, reverse osmosis disinfection) and complete equipment selection and non-standard design based on the raw water quality report (TDS, hardness, turbidity, etc.) and water demand you provide.

We understand that standard products cannot meet all needs. VLLRO provides in-depth OEM/ODM services.

With a demand analysis, start by analyzing your source water quality, water usage, pressure requirements, installation space, etc.

Then customize the solution and customize the design according to your application scenario (industrial water, commercial drinking water, household water purification).

Next is product customization, which can be customized according to your requirements for equipment size, processing capacity, brand logo, exterior color and control system.

There is also accessory customization, flexibly selecting core components such as pumps, membrane elements, and valves of different brands to balance budget and performance.

In addition, there is testing and delivery, and each set of VLLRO customized equipment undergoes rigorous factory testing (including stress testing, performance testing) to ensure that it is delivered to customers around the world after meeting the standards.

Time is money. We ensure that products reach you quickly through efficient in-house management and mature logistics cooperation.

We have a large inventory of regular products, and for standard orders, we promise to pay on the same day as soon as possible, greatly reducing your waiting time.

We maintain long-term cooperation with many well-known international logistics companies and sea freight forwarders, and can recommend the best (air, sea, land) transportation solutions according to your needs to ensure the safe and timely delivery of goods to any corner of the world.

We provide you with a variety of after-sales maintenance services, including full technical guidance, detailed installation manuals, video guides, and online remote installation guidance to ensure that your team can install the equipment correctly.

Online technical support and spare parts supply, we provide lifelong online technical support to answer questions in time during equipment operation. We guarantee a long-term stable supply of wearing parts and spare parts such as filter elements, membrane elements, and sealing rings.

Quality warranty policy, we provide a clear quality warranty period for all products (e.g., 1 year for the whole machine, longer for core components such as membrane shells and pumps). During the warranty period, we provide free repair or component replacement services for failures caused by product quality issues.
