Frequently Asked Questions

What is the main purpose of an ultra-pure water system?
It is used in laboratories, pharmaceutical production, electronics (semiconductors), and fine chemicals requiring high-purity water for cleaning, experimental reactions, and sterilization.
What maintenance and consumables are required?
RO membrane lifespan: 2–3 years; Polishing/ion-exchange cartridges: 6–12 months; UV lamp life: 8,000–12,000 hours. Regular flushing and sterilization are required to prevent microbial growth.
What types of ultra-pure water systems are available?
We offer inline/loop systems for continuous production and recirculating systems for stable water quality storage.
Can the equipment be customized?
Yes, we offer full OEM/ODM customization based on your specific purity requirements and processing capacity needs.
Are you a manufacturer or a trading company?
We are a direct manufacturer with integrated R&D, manufacturing, and export capabilities, offering factory-direct pricing and technical support.
What standards does the water quality meet?
The output water meets ASTM, GB/T 6682-2008, and ISO 3696 laboratory water standards with resistivity up to 18.2 MΩ·cm.
