Description
The UV Dynamics UVD320E is a compact and reliable ultraviolet (UV) water disinfection system engineered for point-of-entry whole-house use in residential, cottage, or light commercial water systems. Built for up to 10 gallons per minute (GPM) flow, this system uses germicidal UV-C light to help inactivate bacteria, viruses, and other microorganisms without the use of chemicals — delivering safe, treated water to faucets, showers, and appliances.
Key Features & Benefits
- Rated flow: Up to 10 GPM (37 L/min) at a UV dose of 30 mJ/cm², and up to 8 GPM (30 L/min) at 40 mJ/cm² for enhanced disinfection performance.
- Stainless steel reactor: Passivated, polished 304 stainless steel chamber (3.5″ × 18″) for corrosion resistance and durability.
- Long-life UV lamp: Coated germicidal lamp rated at ~9,000 hours (~1 year), ensuring reliable service between replacements.
- Smart power source: Microprocessor-controlled ballast with audible and visible lamp failure alarms, annual lamp change reminder, and lamp life remaining feature for confident operation.
- ¾″ MNPT inlet/outlet connections — standard plumbing for straightforward installation.
- User-friendly service: Domed quartz sleeve protects the lamp and simplifies maintenance, and tool-free lamp connector makes annual servicing easier.
- Made in Canada, designed for durability and reliability.

The UVD320E is well suited for homeowners and light commercial users who want chemical-free water disinfection at a robust flow rate. Its design combines trusted UV technology with practical features such as alarm systems and easy annual service, making it a dependable choice when microbial safety is a concern.
Typical Installation & Use
- Install as a point-of-entry pre-treatment on cold potable water (ideally after sediment/carbon filters).
- Pre-filtration recommended (e.g., 5 micron) to ensure delivered UV dosage isn’t compromised by turbidity or solids.
- Annual lamp replacement keeps UV output within effective disinfection levels.
Maintenance & Parts
To keep your system performing at peak levels:
- Replace the UV lamp annually (~9,000 hours). Lamp #400152
- Inspect and clean or replace the quartz sleeve if fouling or cloudiness is present.
- O-rings and seals should be checked during service for a leak-free system.
