- Production Rate: 20L/h, 30L/h
- Dispensing Rate: 1.5–2 L/min (with pressure tank)
- Feed Water Requirements: Urban tap water
- U-type Korean quick-insert filters, using imported filter media.
Ultra-pure Water Purifier, LWP-S3-20VF, LWP-S3-30VF
Descrição
- Built-in filter, witha 10 micron 316L stainless steel precision filter screen to remove fine impurities instead of a PP cotton filter; The manual drain valve allows for automatic cleaning at any time; The soft-scraping design ensures more thorough drainage; The transparent shell makes the filtration effect visible.
- The long-acting KDF device adopts the original imported filter material. It removes residual chlorine, heavy metals, and inhibits the growth of fungi at thepretreatment stage of water purification. It has a long service life, better protects the downstream purification system, and extends the lifetime of the ultra-purification column.
- Built-in pressure tankwith a transparent, antibacterial inner bladder that can be replaced anytime.
- ABS engineering plastic case, with a powder coating technology, featuringwater quality and quantity upgrade functions, and a side-opening door.
- U-type Korean quick-insert filters, using imported filter media.
- Backlit LCD display, and dual‑waterway online monitoring, which can simultaneously display RO conductivity, UP resistivity and equipment operation status.
- Menu-driven operation, parameters can be set and modified, with an operating status display and indicator lights to promptly reflect themachine operating status such as high-pressure shutdown, low-pressure alarm, water-full shutdown, etc.
- Water quality over-limit alarm, automatic filter replacement reminder, water intake time can be set. Water dispensing via touch keys; automatic indicator lights show RO and UP water intake.
- Equipped with a portable test pen, which can test TDS content, conductivity and water temperature anytime, anywhere.
- The pipeline features a quick-connect interface, with NSF-certified pipe joints. Thedual-wavelength UV lamp effectively sterilizes and reduces TOC, and the original imported 5000D ultra-filtration module effectively removes pyrogens.
- Featuring an RS-232C communication interface, it can be connected to intelligent instruments to transmit measurement data or print records (optional).
- The original imported 3-meter telescopic water dispensing gun makeswater collection convenient (optional).
- Can be equipped with an ultra-pure water internal circulation system which keeps the water quality at the highest level (optional).
