UVonic T5 UV Sterilizers MKII 5"
UVONIC
UV STERILIZERS
Professional UV disinfection rated at End-of-Lamp-Life. Every flow rate 3rd party validated. Protection that holds for 16,000 hours.
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.
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.
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.
Every UVonic T5 design has been independently validated by a 3rd party authority on UV disinfection science. Third-party proof. Not marketing claims. Verified science.
Built for Professionals.
Specified for Performance
Every UVonic T5 MKII ships complete — no additional purchases, no missing adapters, no surprises.
Independent 3rd party dose validation applied to every model in the range.
Flow rates published at End-of-Lamp-Life. Performance guaranteed all 16,000 lamp hours.
Premium T5 UV lamps — significantly longer than standard UV lamps, reducing running costs.
Larger irradiation chamber delivers higher flow rates without sacrificing UV dose.
Both union types included. Installs into any existing plumbing — no adapters needed.
Visual confirmation your lamp is running — simple, practical, absent on many competing units.
Countdown timer tracks lamp hours. Indicator light confirms active UV output.
Ponds: 1 turnover/4hr. Aquariums: 1 turnover/hr. Correct hydraulic sizing for real-world results.

What's New in the Lineup
Continuous improvement — same engineering rigour, expanding capabilities.
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.
UV40-T5 — New 40W Model
A new 40W model bridges the gap between the 28W and 48W units — ideal for medium ponds (~18,000 L) and larger display aquariums (~4,500 L). Flow: 75 lpm @ 30 mJ/cm² EOLL.
3" Diameter Models
A compact 3-inch body range is in development — same 3rd party validated 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

Aquatic Systems
From premium koi ponds to commercial aquaculture — if pathogen control matters, UVonic delivers.
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.
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.
UV240-T5 and UV310-T5 double-chamber models deliver industrial-grade UV capacity for RAS, hatcheries, nurseries, live seafood holding, and research facilities.
