♨️ Balboa Ultrazo3ne™ Natural Purification Ozone System – Corona Discharge Spa Sanitiser

Cut your hot tub chemical use by up to 90% with Balboa’s compact, energy-efficient ozone purification technology.

📋 Product Overview

The Balboa Ultrazo3ne™ is a high-efficiency ozone purification system purpose-built for hot tubs and spas. Using advanced corona discharge (CD) technology, this compact unit generates a powerful natural oxidant that destroys bacteria, viruses, and organic contaminants in your spa water — dramatically reducing your reliance on chlorine and bromine.

Designed and manufactured by Balboa Water Group, the global leader in spa control systems for over 20 years, the Ultrazo3ne™ is engineered specifically for the demanding hot tub environment. The fully epoxy-potted construction protects against moisture and corrosion, whilst the unique CD ozone cell with a solid stainless-steel electrode delivers exceptional longevity and stable ozone output across a wide temperature range. At just 78 × 68 × 34 mm, it fits comfortably into even the tightest spa cabinet spaces.

Whether you’re upgrading an ageing ozonator or fitting one for the first time, the Ultrazo3ne™ offers plug-and-play installation for any ozone-ready spa system up to 500 gallons (approximately 1,900 litres).

💧 How Ozone Purification Works

Ozone (O₃) is one of nature’s most powerful oxidising agents — up to 3,000 times more effective than chlorine at destroying bacteria and viruses. The Balboa Ultrazo3ne™ works by converting oxygen molecules into ozone using corona discharge technology, then introducing this ozone directly into your spa water through the included tubing system.

The purification process:

1. The corona discharge cell generates ozone from ambient air drawn through the built-in silicone air filter
2. Ozone is delivered into the spa plumbing via the included 1/4″ tubing and non-return valve
3. The ozone oxidises bacteria, viruses, and organic contaminants on contact
4. After sanitising, the ozone naturally reverts back to oxygen — leaving no chemical residue

This process means your spa water stays cleaner and fresher with significantly less chlorine or bromine, resulting in softer water that’s gentler on skin, eyes, and swimwear.

🛠️ Installation & Compatibility

Connection Type: 4-pin AMP plug — compatible with most Balboa spa control systems and other ozone-ready controllers that accept a standard 4-pin AMP connection.

Installation Requirements:

Requirement	Details
Spa System	Must be ozone-ready with 4-pin AMP ozone port
Voltage Supply	240VAC (supplied via spa control system)
Mounting	Built-in thick mounting tabs for secure installation
Tubing Connection	1/4″ barb fittings (included)
Air Supply	Ambient air via included silicone air filter
Cabinet Space Required	Minimal — unit measures just 78 × 68 × 34 mm

Installation Notes:

⚠️ Mount the ozonator above the waterline to prevent water backflow through the tubing.

⚠️ Always install the included non-return (check) valve to protect the unit from water damage.

⚠️ Ensure the silicone air filter is clean and unobstructed for optimal ozone production.

⚠️ If your spa is not ozone-ready, you may need an ozone saddle clamp or inline bypass kit (sold separately).

⚠️ Installation should be carried out by a qualified spa technician in accordance with manufacturer guidelines and local electrical regulations.

💬 Frequently Asked Questions

Q: Will this ozone generator fit my hot tub? A: The Ultrazo3ne™ is compatible with any ozone-ready spa that uses a standard 4-pin AMP connection at 240V. This covers most Balboa-controlled spas as well as many other brands. If your spa doesn’t have a dedicated ozone port, you may need an ozone saddle clamp or inline bypass kit.

Q: Does ozone completely replace chlorine or bromine? A: Ozone dramatically reduces the amount of chemical sanitiser needed — by up to 90% — but a small residual amount of chlorine or bromine is still recommended to maintain sanitation when the ozonator is not running. Think of ozone as your primary sanitiser with chemicals as a backup.

Q: How long does the unit last? A: The Ultrazo3ne™ has a rated lifespan of up to 5 years under normal use conditions. The fully epoxy-potted construction and solid stainless-steel electrode are specifically designed for longevity in the harsh spa environment.

Q: Is it noisy? A: No. The Ultrazo3ne™ operates silently with no moving parts. You won’t hear it running in your spa cabinet.

Q: How do I know it’s working? A: The built-in LED indicator light provides visual confirmation that the unit is operating. You should also notice clearer, fresher-smelling water and a reduced need for chemical top-ups.

Q: Does it use a lot of electricity? A: Not at all. The Ultrazo3ne™ draws just 0.17A maximum — a fraction of the energy used by conventional UV ozone generators. The running cost is negligible.

Q: What maintenance does it need? A: Very little. Keep the silicone air filter clean and unobstructed, ensure the tubing and check valve remain in good condition, and replace the unit when ozone output diminishes after several years of use.

Q: Can I install it myself? A: If your spa is ozone-ready with a 4-pin AMP port, installation is straightforward plug-and-play. However, we always recommend having a qualified spa technician carry out the installation to ensure everything is connected correctly and safely.
