Description
Elevate spa water quality with the Del Ozone UO3 Ozonator, a high-output ozone generator built on the trusted MCD-50 platform. This compact unit blends advanced ozone technology with complete injection, mixing, degas, and destruct options to deliver powerful oxidation while prioritizing safety. With a proven track record since 2003, DEL’s ozone systems are designed for reliability, serviceability, and a longer lifespan than typical spa ozonators.
Designed for spas up to 500 gallons, the UO3 ozonator packs a steady 30 mg/hr ozone output (580 PPM) at a modest 2 cfh flow. It runs on 115V or 230V, with adjustable ozone output to match your spa’s needs. The compact footprint (8.6" H x 6.1" W x 2.8" D) and light weight (3.75 lbs) make it an easy upgrade or replacement in existing systems that use the MCD-50 platform.
Why this Del Ozone unit stands apart
- High-output, long-term reliability: Reputed for the longest lifespan of any spa ozone generator on the market—typically around five years—with serviceable design for easier maintenance and replacement.
- Integrated MCD-50 functionality: Utilizes the same robust MCD-50 approach you’ve seen in spa installations since 2003, but now in a smaller, more adaptable form factor to meet growing replacement demand.
- Comprehensive ozone management: Complete injection, mixing, degas, and destruct options ensure ozone is delivered efficiently where your spa needs it, maximizing water quality while minimizing byproducts.
- Versatile power and output: 115V at 55 mA (2.9W) or 230V at 132 mA (4.2W), with adjustable output to suit different spa sizes, bather loads, and water chemistry.
- Proven compatibility and ease of upgrade: Specifically designed for spas that originally use the DEL MCD-50 system and now offered as a compact replacement with the same output.

What problems does it solve? Who is it for?
- For spa owners seeking clearer, cleaner water: Higher ozone output accelerates oxidation of organic contaminants, reducing chlorine or bromine demand and diminishing odor and haze.
- For service professionals and installers: A reliable, serviceable ozone generator with a smaller footprint that preserves the proven MCD-50 performance you trust in-field.
- For families and bathers with sensitive skin or allergies: Lower chemical load in the water without sacrificing disinfection, thanks to consistent ozone dosing.
- For upgrades and replacements: A drop-in replacement that maintains output while fitting modern spa enclosures, with all necessary connections included.
Practical tips and best-use scenarios
- Match ozone output to your spa size and usage; larger baths or higher bathers-per-day may benefit from the adjustable output option.
- Ensure proper installation with the included 1/4" check valve and tubing, then secure with the supplied clamps and mounting hardware for vibration-free operation.
- Periodically inspect connections and the tubing for signs of wear to maintain optimal ozone delivery and system lifespan.
- Consider pairing with a spa water testing routine to monitor ozone-related oxidation markers and adjust as needed for balanced water chemistry.
With its proven DEL pedigree, the Del Ozone UO3 Ozonator (51002-002-107) delivers robust ozone performance in a compact package. It’s the dependable choice for spa enthusiasts who demand clearer water, reduced chemical use, and a durable, replaceable ozone solution that grows with their spa system.
