🔬 How It Works

The H.R.UV-C Double Pro employs advanced UV-C technology combined with a revolutionary super reflective chamber and intelligent chemical dosing:

Water enters H.R.UV-C → Passes through E-PTFE reflective chamber → Dual UV-C lamps destroy microorganisms → Dosing pump adds residual sanitiser →

1️⃣ E-PTFE SUPER REFLECTIVE CHAMBER

The unique E-PTFE (Expanded Polytetrafluoroethylene) reaction chamber provides the highest UV reflective index on the market. This extremely repellent material maintains up to 95% UV reflection, dramatically amplifying the exposure of microorganisms to sterilising UV-C radiation.

2️⃣ DUAL UV-C LAMP STERILISATION

The powerful dual 55W low pressure/high output UV-C lamps (110W total) emit germicidal ultraviolet light at 254 nanometres. This wavelength penetrates microorganism cell walls and disrupts their DNA/RNA, preventing reproduction and effectively neutralising:

• Bacteria
• Viruses
• Algae
• Fungi
• Parasites (including Cryptosporidium and Giardia)

3️⃣ AMPLIFIED PATHOGEN DESTRUCTION

The combination of dual UV lamps and the super reflective E-PTFE chamber means microorganisms receive multiple exposures to UV-C radiation as light reflects throughout the chamber. This dramatically increases sterilisation efficiency compared to standard UV systems.

4️⃣ INTELLIGENT CHEMICAL DOSING

The integrated peristaltic dosing pump automatically delivers hydrogen peroxide (H₂O₂) or liquid chlorine at your programmed time each day, ensuring consistent residual sanitisation between UV treatments.

→ Only sterilised and sanitised water returns to your pool

❓ Frequently Asked Questions

Q: What is the difference between Classic and Pro models?

A: The Pro model includes a digital lamp life countdown (showing exact hours remaining) instead of analogue indicator, plus an intelligent peristaltic dosing pump for automated chemical delivery. Classic models have analogue indicators and no dosing pump.

Q: What chemicals can the dosing pump handle?

A: The system is pre-programmed for two chemical types: Hydrogen Peroxide (H₂O₂/Active Oxygen) and Liquid Chlorine. The controller automatically adjusts H₂O₂ dosing based on water temperature.

Q: How does the chlorine dosing work?

A: For liquid chlorine, the daily dose is split into two deliveries — CL1 (morning) and CL2 (afternoon) — for more even distribution throughout the day. You programme the time and volume for each dose.

Q: What is the shock dose function?

A: Shock dose allows you to immediately deliver a chosen volume of chemical to the pool. This is useful after heavy bather loads, pool parties, or when water quality tests indicate issues.

Q: How often should I replace the dosing tube?

A: The dosing tube should be replaced every 6-12 months to maintain optimal performance and prevent wear.

Q: What size pool is this suitable for?

A: The HRP-110-UK is designed for pools up to 110,000 litres (110m³) with a minimum filtration turnaround of three times per day.

Q: Will this fit my system?

A: The H.R.UV-C connects via 2″/63mm stepped ABS unions, with reducers included for 1½”/50mm pipe. Maximum flow rate is 32m³/h.

Q: How long do the UV lamps last?

A: Each lamp has a usable life of 9,000 hours under normal conditions (approximately 2 years). The digital display shows exact hours remaining.

Q: What happens during a power cut?

A: Programmed settings (dosing volume and time) are retained during power loss. If power is off for more than 3 hours, the current time will need to be reprogrammed (indicated by flashing clock).

Q: Is this compatible with salt water?

A: Yes. The H.R.UV-C is 100% compatible with chlorinated salt water and sea water pools.

Q: What’s the warranty?

A: 2 years within Europe, 1 year outside Europe. The warranty does not include serviceable parts such as lamps, quartz sleeves, O-rings, and dosing tubes.
