UV Swim: UV Pool System for Commercial Pools (NSF50 Certified)

UV Swim is a UV Pool System engineered specifically for swimming pools and leisure facilities that demand consistent clarity, reduced chloramines, and protection against chlorine-resistant microorganisms. NSF50 Certified for critical aquatic treatment, UV Swim provides powerful secondary or supplemental disinfection without increasing chemical load or operational complexity.

From aquatic centres to hotel pools and high-bather-load water parks, UV Swim is designed to protect swimmers, safeguard reputations, and reduce the risk of costly shutdowns.

NSF50 Certified Secondary and Supplemental UV Pool Systems

UV Swim systems are built specifically for pools that require either secondary or supplemental disinfection — and the distinction matters. Both UV Swim U and UV Swim I are designed to support improved indoor air quality, better water clarity, greater swimmer comfort, and reduced corrosion risk in pool halls.

UV Swim system details

Expand the sections below to compare UV Swim U and UV Swim I, review key technical features, and understand specification requirements.

What is UV Swim U?

UV Swim U meets NSF50 requirements for supplemental disinfection and is designed to aggressively reduce combined chlorine in swimming pools.

It delivers ≥3-log reduction of Enterococcus faecium and Pseudomonas aeruginosa while breaking down mono-, di-, and trichloramines at the molecular level.

Using medium-pressure UV operating between 200–400 nm, UV Swim U improves:
• Indoor air quality
• Water clarity
• Swimmer comfort

For facilities focused on odour reduction, air quality improvement, and stabilising chlorine demand, UV Swim U enhances existing treatment without major plant room redesign.

What is UV Swim I?

UV Swim I is NSF50 Certified for critical aquatic treatment. It is engineered to meet MAHC, US EPA UVDGM and DVGW requirements and is specified where secondary UV disinfection is required.

UV Swim I provides effective protection against chlorine-resistant microorganisms such as Cryptosporidium and Giardia while also reducing chloramines in high-demand facilities.

For aquatic centres, competition pools, and high-bather-load environments, UV Swim I reduces outbreak risk, inspection exposure, and the operational consequences of pathogen incidents.

Both systems integrate directly into pool return lines and are engineered specifically for swimming pool hydraulics — not adapted from industrial water applications.

What are the key technical features of UV Swim systems?

UV Swim is not a generic UV chamber. It is engineered for swimming pool plant rooms where reliability, footprint, and operating efficiency matter.

UV Swim I features:
• Medium-pressure lamps with 8,000 hour expected life
• Stepless variable power with up to 70% reduction from maximum ballast power
• Dry DVGW-approved UV sensor for continuous performance verification
• Modbus RS485 communication for SCADA integration

UV Swim U features:
• Medium-pressure UV with 8,000 hour lamp life
• 4-level power stepping for energy control
• Wet UV monitoring to minimum UVT
• UL listed systems for US markets

Both systems include automatic quartz wipers for reduced maintenance and operate at up to 6 bar working pressure.

This is engineered UV performance designed for real-world aquatic facilities.

How do I choose the right UV Swim system?

Every pool has different hydraulic conditions, bather loads, and compliance requirements.

Selecting the correct UV Pool System requires:
• Maximum flow rate
• Minimum UVT conditions
• Disinfection objective (secondary vs supplemental)
• Electrical supply configuration
• Plant room footprint

UV Swim systems are available across a wide flow range to suit everything from spas to large aquatic facilities, with documented NSF50 certification and technical support packs available for consultants and operators.

Whether you are upgrading an existing chlorine-only system to include a UV system for secondary or supplemental disinfection, or specifying a UV system for a new aquatic facility, our team will size and configure the appropriate UV Swim system for your application.
