True multi-lamp geometry
Lamp placement changes everything in a multi-lamp reactor. Our engine models up to 10 lamps by exact X/Y position, arc length and output — so dose is engineered, not assumed from a single-lamp chart.

The UVONIC CMLA — Commercial Multi-Lamp Amalgam Series — is engineered around one principle: every reactor is sized to your actual dose target. Most commercially available UV calculators only model stainless steel chambers. Ours models the real world — stainless, white PVC and dark/black HDPE all reflect and absorb 254 nm UV differently, and that changes the delivered dose. Our in-house MPSS dose engine — BTA's custom-built UV steriliser engineering software — places every lamp, models chamber material, water transmittance and geometry, and validates the result against industry-standard UV software to within 1%. The software is as much a part of every UVONIC build as the reactors themselves: it brings another level of accuracy to UV sizing that generic charts cannot match.
The UVONIC difference
Sized by modelling. Not by guesswork.
Three things set the UVONIC series apart from off-the-shelf commercial UV units.
Chamber material matters
Stainless steel, white PVC and dark/black HDPE reflect 254 nm UV very differently. The calculator applies material-specific geometry factors so a PVC or HDPE build is sized honestly.
Validated accuracy
The MPSS engine uses 124,480 probe points with 80-point Gauss-Legendre quadrature and matches industry-standard UV software within 1% on reference cases.
In-house engineering
Every reactor is modelled before it is built
We size every UVONIC reactor with our own UV dose calculator — a high-resolution MPSS engine that accounts for lamp placement, chamber material, water transmittance and reactor geometry. Here is a look at the tool we use in-house.
Reactor parameters
Chamber dimensions, sleeve size, flow rate and water %T at 254 nm are entered for your system — not a generic worst case.
Lamp-by-lamp layout
Up to 10 lamps placed by exact X/Y position with individual wattage, arc length and efficiency — the layout that actually goes into your reactor.
Dose you can check
New-lamp dose, end-of-lamp-life dose and a 10% safety-factor design value are reported for every configuration.
Fluence distribution
See the dose before you buy
The engine produces a cross-section fluence map of the reactor — orange circles are lamp sleeves, contour lines show iso-fluence levels. This is the same output we use to verify that every corner of the chamber receives the designed dose.

Complete the treatment train
UV works best on clear water. Pair the UVONIC with filtration that removes the solids and colour that shield pathogens from UV light.
Protein skimmers & foam fractionation
Remove fine solids and dissolved organics before UV treatment for better transmittance and dose delivery.

Design philosophy
Why no LCD screen or UV intensity sensor?
No LCD screen
LCD displays add significant cost to commercial UV control boxes without adding treatment value. The UVONIC control box carries the meters that actually matter: voltage, on/off status, per-lamp bulb indicators and over-temperature sensing.
No UV intensity sensor
In a multi-lamp reactor a single intensity sensor cannot read the chamber accurately — if a lamp on the far side of the reactor fails, a spot sensor still shows healthy output. Every UVONIC unit is instead sized to the target dose with end-of-lamp-life factors built into the design.
Frequently asked questions
UVONIC FAQs
What chamber sizes are available?
The current range covers 280 mm and 315 mm chambers, with more sizes in development. Custom configurations are available on request.
Can the reactor be mounted vertically or horizontally?
Yes. UVONIC reactors are built to any format — vertical or horizontal — with interchangeable inlet and outlet connections in customisable sizes to suit your pipework.
Does chamber material really change the UV dose?
Yes. Stainless steel, white PVC and dark/black HDPE reflect 254 nm UV differently, which changes the delivered dose. Our dose calculator applies material-specific geometry factors so every build is sized honestly for its actual chamber material.
How accurate is your dose modelling?
The MPSS engine uses 124,480 probe points with 80-point Gauss-Legendre quadrature and matches industry-standard UV software within 1% on reference cases — for example, a validated five-lamp 320 W case returned 154.75 mJ/cm² against a reference 155.67 mJ/cm².
Why doesn't the control box have an LCD screen or UV sensor?
LCD screens add substantial cost without treatment benefit, and in a multi-lamp reactor a single UV intensity sensor cannot accurately measure chamber output — especially if a lamp on the opposite side fails. Instead, each lamp has its own ballast and indicator light, and every unit is sized to its target dose rate with end-of-lamp-life factors included.
Can I get flow monitoring?
Yes. Flow meters with low and high transducer switches are available as an option — they also serve as a backup to the over-temperature sensor included as standard.
Not sure what your UV is actually doing?
Want to check the sizing of an existing unit, or retrofit a UV reactor to another system and verify the dose rate? That is exactly what we built our UV calculator for. Send us your flow rate, water transmittance and target dose — we will model it and give you the numbers.
