🔬 How It Works

The H.R.UV-C Single Pro utilises advanced high reflection technology to maximise UV-C sterilisation effectiveness:

Pool Water → Pump → Filter → Heater → H.R.UV-C → Chemical Dosing → Return to Pool

1️⃣ E-PTFE REACTION CHAMBER Water enters the UV chamber lined with E-PTFE (expanded polytetrafluoroethylene), an extremely repellent material that maintains UV reflectivity throughout the product’s life.

2️⃣ HIGH REFLECTION UV-C STERILISATION The 55W low pressure/high output UV lamp emits UV-C radiation. The E-PTFE chamber reflects up to 95% of this radiation, dramatically amplifying microorganism exposure and destroying bacteria, viruses, algae and fungi that traditional chemicals cannot neutralise.

3️⃣ INTELLIGENT CHEMICAL DOSING The integrated peristaltic pump automatically doses hydrogen peroxide or liquid chlorine at programmed intervals, maintaining optimal sanitisation levels without manual intervention.

Key Benefits:

• No harmful gases or by-products produced
• Neutralises bacteria, viruses, algae and fungi that traditional chemicals cannot
• Powerful sterilisation eliminates the smell of chlorine
• E-PTFE chamber maintains reflectivity – no degradation over time

🖥️ Digital Lamp Life Indicator System

The HRP-55-UK features an advanced digital countdown display showing exact remaining lamp hours:

LED Colour	Hours Remaining	Status	Action Required
🟢 Green	9,000 – 500 hours	Normal operation	None
🟡 Amber	499 – 1 hours	Lamp life low	Order replacement lamp
🔴 Red	0 hours	Lamp expired	Replace lamp immediately

Digital Features:

• Precise countdown from 9,000 hours
• Automatic LED colour change at threshold points
• Power failure does not affect lamp life countdown
• Simple reset procedure after lamp replacement
• Multi-language menu selection on power-up

💊 Intelligent Dosing System

The integrated smart peristaltic dosing pump provides automated chemical injection with two programmable modes:

Mode A: Hydrogen Peroxide (H₂O₂) Dosing

Dosing Table – H₂O₂ at 32% Concentration, 28°C Water Temperature:

Pool Volume	Daily Dose
35m³	200ml/day
50m³	320ml/day
60m³	420ml/day
80m³	620ml/day
90m³	700ml/day
100m³	800ml/day
130m³	1,040ml/day
150m³	1,200ml/day

💡 Note: For 12% concentration H₂O₂, multiply dosing amounts by 3. The digital controller automatically senses water temperature and adjusts the required dose accordingly.

Mode B: Liquid Chlorine Dosing

Dosing Table – Stabilised Liquid Chlorine (Split CL1 + CL2):

Pool Volume	Daily Dose	Split Dosing
10m³	200ml/day	100ml + 100ml
20m³	400ml/day	200ml + 200ml
30m³	600ml/day	300ml + 300ml
40m³	800ml/day	400ml + 400ml
50m³	1,000ml/day	500ml + 500ml
60m³	1,200ml/day	600ml + 600ml

💡 Note: Daily chlorine dose is split between morning (CL1) and afternoon (CL2) delivery for optimal distribution. Dosage is approximate and dependent on pool volume, local water type, temperature, positioning, bather loading and weather conditions.

Shock Dose Function

The shock dose feature enables immediate dosing with a chosen volume following heavy pool use or water condition changes. Simply select the volume and confirm – dosing begins immediately when the filtration pump is operational.

❓ Frequently Asked Questions

Q: What is High Reflection UV-C technology? A: H.R.UV-C uses an E-PTFE (expanded polytetrafluoroethylene) reaction chamber that reflects up to 95% of UV-C radiation, dramatically increasing microorganism exposure compared to standard UV systems. This makes it the highest UV reflective index on the market.

Q: What size pool is this suitable for? A: The HRP-55-UK is designed for pools up to 55,000 litres (55m³) with a minimum filtration turnover of three times per day.

Q: Will this fit my existing pipework? A: The unit comes with 2″/63mm stepped ABS unions plus 1½”/50mm reducers included, compatible with most pool plumbing systems.

Q: What is the maximum flow rate? A: Maximum flow rate is 16m³/h (16,000 litres per hour). Higher flow rates require a bypass installation.

Q: What voltage does this require? A: Single phase 100-240V at 50/60Hz. Maximum power consumption is 64W. Installation by a qualified electrician with 30mA RCD protection is required.

Q: How often do I need to replace the lamp? A: The lamp has a 9,000 hour life (approximately 2 years average). The digital countdown display shows exact hours remaining, changing from green to amber at 499 hours and red at 0 hours.

Q: What chemicals can the dosing pump handle? A: The intelligent dosing pump is pre-programmed for hydrogen peroxide (H₂O₂/Active Oxygen) or liquid chlorine. It features daily programmable dosing times (split CL1+CL2 for chlorine) and a shock dose function.

Q: Is it compatible with salt water pools? A: Yes, the H.R.UV-C is 100% compatible with chlorinated salt water and sea water systems.

Q: Can I mount it vertically or horizontally? A: Yes, both mounting orientations are supported. Ensure 1 metre clearance from one side for lamp and quartz sleeve access during maintenance.

Q: What warranty is provided? A: 2 years within Europe, 1 year outside Europe. The warranty does not cover serviceable parts (lamps, quartz sleeves, O-rings) or damage from incorrect installation, inappropriate use or neglect.

Q: Will this eliminate the need for chemicals entirely? A: The H.R.UV-C significantly reduces chemical requirements and eliminates chlorine smell, but should be used alongside a residual sanitiser. The integrated dosing pump automates this process.

Q: What maintenance is required? A: Annual maintenance includes lamp replacement (when indicated), quartz sleeve inspection and cleaning, O-ring replacement, and dosing tube replacement every 6-12 months.
