Why UV instead of chemicals
No chemicals, no residuals
Nothing is dosed into the water and nothing has to be removed downstream. No by-products, no taste or odour impact, no storage or handling of hazardous chemicals on site.
Lower OPEX
The running cost is electricity plus one lamp and seal set per service interval — against continuous chemical purchase, dosing equipment and neutralisation.
Validated dose, not a guess
HOD UV reactors monitor UV intensity and UVT in real time, so the delivered dose is measured continuously rather than assumed from a contact time.

Applications
Where HOD UV replaces or protects existing treatment. Each card links to the manufacturer's published application page.
Disinfection
Process and product water, simple syrup, Legionella control in service water systems.
Food & Beverage↗
Dechlorination
UV breaks free and combined chlorine without SMBS or carbon — no residuals, no consumable chemistry.
Technology↗
RO protection
Removes the biological load ahead of the membranes — fewer CIPs, longer membrane life.
Industry↗
Biofouling control
Cooling water, heat exchangers and intake lines — control of algae, mussels and biofilm without biocides.
Industry↗
Aquaculture
RAS, hatcheries, well-boats and marine operations — biosecurity without chemical residues in the fish water.
Aquaculture↗
Biopharma
WFI and PW loop disinfection, ozone destruction, TOC reduction.

Not sure which system fits?
Send us the water data — flow rate, UVT, application and target dose — and we come back with a sized system and a budget figure. It takes two minutes to fill in.
Find the code shown on your controller and work through the steps in order. Codes and wording differ between controller generations — always cross-check against the manual supplied with your system. Work inside the control cabinet is for qualified electrical personnel only: isolate and lock out the supply before opening. If the fault is still there after the last step, send us a service request with the serial number, lamp hours and the error log — that is everything we need to respond the same day.
Critical — system stopped
E01Lamp failed to ignite
- Check ballast module power and the wiring harness
- Inspect the lamp and the lamp connector pins
- Replace the UV lamp
- If unchanged — replace the ballast module
E03UV sensor out of range
- Clean the quartz sleeve and the sensor window
- Check the UVIS cable and connector
- Replace the UV sensor (OPB000100)
- Calibrate against the master sensor kit
E12Ballast overheating
- Check cabinet ventilation and filters
- Clean the cooling fins
- Verify ambient temperature is within spec
- Replace the ballast module
E99Emergency shutdown
- Cut power and isolate the system
- Read and export the controller error log
- Contact Atlantis-UV — do not restart before clearance
Warnings — running degraded
W02UV output below setpoint
- Check lamp age against the 6,000 h interval
- Clean the quartz sleeve
- Measure UVT — check upstream water quality and turbidity
W05Leak at quartz sleeve
- Isolate and depressurise the reactor
- Inspect the sleeve O-ring (MP0023000) and sleeve holder O-ring (MPE007500)
- Re-seat or replace the seal, then run the return-to-service checklist
Communication / interface
E07No flow sensor signal
- Verify water flow is actually present
- Check the flow sensor wiring and the 4–20 mA loop
- Confirm the interlock configuration on the controller
I01No controller comms
- Check the RS485 wiring and termination
- Verify the Modbus address and baud rate
- Restart the controller
Service checklists
Open a checklist, tick the items as you go, fill in the site details at the bottom and send the completed report to Atlantis-UV — or print it as a PDF for your own logbook. Your progress is saved in this browser as you fill it in, so you can close the page and come back. It is cleared once the report is sent.

Special procedures
Shipped from our Budapest warehouse — anywhere in the EU without import formalities, typically 2–5 days. Fast-moving items (lamps, quartz sleeves, seal sets, UV sensors) are held in stock; everything else is ordered against your enquiry. Part numbers are the original Atlantium catalogue numbers. Availability and lead time for each line are confirmed with your quotation, usually the same working day.
Original Atlantium parts only. Aftermarket and copy lamps are on the market and they do not match the spectral output the reactor was validated for — the controller still reports a dose, but the delivered dose is no longer the one in your validation report, and the warranty is void. Every part in this catalogue is supplied from Atlantium with its original part number. If you have been offered a "compatible" lamp, send us the part number and we will check it.
Recommended site spare set
What every operating plant should hold on site so a lamp or seal failure never becomes downtime. One set per installed reactor — quoted as a package on request.
