Australian Designed & Distributed
Most UV sterilizers publish their performance at brand-new lamp output — the best-case scenario that degrades quickly. Every UVonic flow rate is published at End-of-Lamp-Life (EOLL) — so the dose you are buying still works 16,000 hours later.

Why Smart Operators Choose UVonic

Three engineering principles that separate UVonic from every other UV sterilizer on the Australian market.

Rated at End-of-Lamp-Life (EOLL)

UV lamp output degrades over time. Most brands publish best-case new-lamp figures. Every UVonic flow rate is published at EOLL — protection that holds for the entire 16,000-hour lamp lifespan.

📈

UVT 90% Design Standard

All UVonic units are sized to UVT 90% — the professional standard used in municipal water treatment and commercial aquaculture. Accurate sizing, conservative design, real-world results.

What's New in the UVonic Lineup

Continuous improvement — same engineering rigour, expanding capabilities.

⇧ UPGRADED

UV28-T5 — 25W Upgraded to 28W

The UV28-T5 has been upgraded from 25W to 28W. If you previously had the 25W model, the replacement is now the 28W unit. Better UV output and flow performance — same price, same form factor, drop-in compatible.

✚ NEW

UV40-T5 — New 40W Model

A new 40W model bridges the gap between the 28W and 48W units — ideal for medium ponds (~19,200 L) and larger display aquariums (~4,800 L). Flow: 80 lpm @ 30 mJ/cm² EOLL.

⏱ COMING SOON

3" Diameter Models

A compact 3-inch body range is in development — same Bolton-verified engineering, EOLL dose rating, and UVT 90% standard. Designed for smaller systems, tighter installations, quarantine tanks, breeding facilities, and compact RAS setups. Register your interest → info@btaqua.com.au

Built for Serious Aquatic Systems

From premium koi ponds to commercial aquaculture — if pathogen control matters, UVonic delivers.

🌊

Ponds

Koi, goldfish, and native fish face continuous pathogen pressure. UVonic units sized for 1 complete pond volume turnover every 4 hours — consistent treatment on the correct hydraulic schedule.

🕘

Large-Scale Aquariums

Marine, reef, and high-stocking display systems demand aggressive UV programs. UVonic targets 1 full volume turnover per hour — meeting the elevated demands of closed recirculating systems.

🧪

Professional Aquaculture

UV240-T5 and UV310-T5 double-chamber models deliver industrial-grade UV capacity for RAS, hatcheries, nurseries, live seafood holding, and research facilities.

Common Questions

Q What does EOLL mean and why does it matter?
EOLL stands for End-of-Lamp-Life. UV lamp output decreases over time. Most manufacturers publish at new-lamp output. UVonic flow rates are published at the end of the lamp's 16,000-hour lifespan — the stated 30 mJ/cm² dose is what you get even from an aging lamp. Honest, conservative numbers for the entire lamp service life.
Q What is UVT 90% and why is it used?
UVT 90% is the professional standard used in water treatment and commercial aquaculture — representing clean, well-managed water. Designing to this standard ensures accurate sizing with inherent conservatism built in for real-world conditions.
Q What turnover rate should I use to size my UV?
Ponds: 1 full volume turnover every 4 hours. Aquariums: 1 turnover per hour. When in doubt, size up — a UVonic running below its rated flow always delivers more dose, not less.
Q What is Bolton Photosciences and why does it matter?
Bolton Photosciences is the globally recognised authority in UV disinfection science — the same organisation that verifies UV systems for municipal water treatment worldwide. Verification means the design has been independently confirmed to deliver the stated dose at the stated flow rate. Independent science, not marketing claims.
Q Do UVonic units include unions for Australian plumbing?
Yes. Every unit ships with both imperial and metric unions — installs directly into your existing plumbing in inches or millimetres. No adapters required.
Q How long do UVonic lamps last?
UVonic T5 UV lamps are rated to 16,000 hours — significantly longer than standard UV lamps (typically 8,000–9,000 hours). At 24/7 operation this is approximately 22 months between lamp changes. The countdown timer tracks hours to the service interval.
Q What is the difference between single and double chamber models?
Single chamber models (UV28 through UV155) use one UV lamp in a single irradiation chamber. Double chamber models (UV240-T5 and UV310-T5) use two chambers in series, doubling irradiation capacity for the highest flow rate applications.
Q When are the 3" models available?
The 3" diameter UVonic models are currently in development using the same Bolton-verified design process, EOLL dose rating, and UVT 90% standard. Email info@btaqua.com.au to register your interest and be notified on launch.
