Germ-free drinking water – safe with certified UV-C technology

oxytec systems for effective disinfection of drinking water – without chemicals, without residues

Drinking water is a hygiene-critical resource both in production and in buildings. Even with a regularly checked supply, germs, bacteria and viruses can multiply in pipes, tanks or taps – especially in the event of stagnation, warm temperatures or backflows. This can lead to hygiene problems, system contamination or health risks.

With the certified UV-C systems from oxytec, drinking water is 99.999 % germ-free – without any chemicals, changes in taste or environmental pollution. The technology is durable, low-maintenance and safe to use in flow-through operation.

What would you like to know?

Simply put your question to our AI. They will answer you individually:

Typical sources of germs in the drinking water system

Source Load potential Special features
Piping systems Biofilm, Legionella, Pseudomonas Stagnation, dead pipes, irregular use
Storage tanks & containers Germ proliferation with heat, sediments, algae Especially in stainless steel or plastic tanks
Return flows / external inputs Germs from systems, fittings or tankers Hazard due to inadequate backflow or filter protection
Final tapping points Hygiene problems at taps, dispensers, appliances Touched outlets, invisible sources of germs

Why drinking water disinfection with UV-C makes sense

Bacteria and viruses can multiply uncontrollably despite standard values in the system

Chlorination or ozonation leave residues, change the taste and are not always permitted

UV-C acts directly and physically – without additives or reaction by-products

The effect is sustainable, certifiable and can be reliably documented

The systems are also suitable for industrial drinking water and sensitive applications

Legal requirements & hygiene standards

  • TrinkwV (Drinking Water Ordinance): microbiological requirements mandatory
  • DVGW W 294-1: Guideline for UV systems in drinking water technology
  • HACCP integration: safe water quality as CCP or oPRP
  • Verification for health and food authorities

oxytec supplies certified systems with test report, calibration and documentation.

FAQ – häufige Fragen

Which germs are safely inactivated by UV-C?

oxytec UV-C systems eliminate reliably:

  • Bacteria (e.g. Escherichia coli, Pseudomonas, Legionella)
  • Viruses (e.g. norovirus, adenovirus, rotavirus)
  • Parasitic pathogens (e.g. Cryptosporidium, Giardia)
  • Spore formers (e.g. clostridia)

The germ reduction is up to 99.999 % (5 log levels) – scientifically proven and certified.

How does disinfection work without chemicals?

The water is passed through a UV-C chamber using the flow-through method

The radiation at 254 nm destroys the genetic material of germs

The process is physical, immediately effective and residue-free

No aftertaste, no dosing agents, no reaction products

How much maintenance is required for the UV systems?

The systems are very low-maintenance:

  • UV-C lamps have a service life of 8,000-10,000 operating hours
  • Regular lamp replacement once a year, depending on operation
  • The quartz protective cover should be inspected regularly and cleaned if necessary
  • Optionally with automatic runtime monitoring and replacement indicator

Are the systems certified for use in drinking water pipes?

Yes – oxytec offers:

  • DVGW-approved models according to W 294-1

  • Devices with testing according to DIN EN 14897 / EN ISO 9001

  • Systems with validated germ reduction and calibration protocol

  • Approval documents for drinking water authorities or hygiene offices

Can UV-C disinfection be integrated into existing drinking water pipes?

Yes – the systems are:

  • compact and modular, for pipes from DN 20 to DN 100+
  • Can be installed horizontally or vertically, even in tight spaces
  • Can be retrofitted to a central feed or in partial circuits
  • Can be integrated into existing water filters, softeners, tank systems or tapping points

How high is the energy consumption of a UV-C drinking water system?

Very low:

  • Typical power: 20-80 watts, depending on the flow rate
  • Electricity costs mostly < 1 €/month in continuous operation
  • No additional costs for chemicals, storage or dosing pumps

How is the effectiveness proven and documented?

oxytec delivers on request:

  • Proof of germ reduction (log levels) for specific pathogens
  • Certificates, calibration protocols and proof of maintenance
  • Support with registration as oPRP or CCP in the HACCP system
  • Audit-ready documents for authorities, certifiers and food control authorities

Can they also be used in sensitive areas such as food production or hospitals?

Yes – UV-C disinfection is ideal for:

  • Food processing (washing water, ice machines, process water)
  • Beverage production (brewing water, mixing circuits, tank rinsing)
  • Hospitals, care facilities, commercial kitchens, schools
  • All facilities with increased hygiene requirements or mandatory testing

Is UV-C safe for the piping system?

Yes – UV-C only affects the water load inside the reactor:

  • No corrosion, no material degradation, as no oxidizing agents are used
  • Suitable for stainless steel, plastic and composite systems
  • No pressure loss, if correctly dimensioned
