Excelight EL720AK 8 GPM UV Water Disinfection System
Designed for whole-house, point-of-entry (POE) microbial protection, the Excelight EL720AK by Waterite Technologies is a reliable UV sterilizer built to help inactivate bacteria, viruses, and other pathogens in potable water using chemical-free ultraviolet light.
Key Features
- Flow Rate: Rated up to 8 GPM (30 L/min) for typical residential use. At this flow, the unit delivers about 30 mJ/cm² UV dose, which meets standard industry disinfection expectations. At lower flows (≈6 GPM) it can achieve higher UV doses (~40 mJ/cm²).
- Lamp Life: High-output UV bulb with about 9,000 hours (~1 year) of effective germicidal operation.
- Stainless Steel Chamber: Durable 304 stainless steel reactor for corrosion resistance.
- Easy Installation: ¾″ MNPT inlet/outlet ports and compact design make it straightforward to install in line with plumbing.
- Built-In Alarms: Audible and visible lamp failure indicators plus lamp life countdown and override feature for maintenance reminders.
- Includes: Lamp, quartz sleeve, ballast/power supply, and installation hardware (varies by retailer).
Why Choose the Excelight EL720AK
- Chemical-free UV disinfection: Helps protect against microbiological contaminants such as E. coli, coliforms, Cryptosporidium, and Giardia without affecting taste, odour, or water chemistry like chlorine does.
- Point-of-Entry protection: Installed on the main water line, it safeguards all faucets and water outlets in a home, cottage, or similar property.
- Built-in reminders and alarms assist with annual lamp replacements and system monitoring.
Product Uses
This system is ideal for:
- Whole-house UV disinfection on well or untreated water supplies
- Residential & cottage applications seeking safe drinking water
- Pre-filtered municipal supplies where biological contaminants are of concern
- (Note: Always pre-filter water to <1 NTU and low iron/tannins for best UV performance.)
Typical Maintenance
- Annual UV lamp replacement (~9,000 hours).
- Clean or replace the quartz sleeve if mineral scale or staining reduces UV transmission.
