Product Features


High-Efficiency Solar Vacuum Tubes

Advanced Absorption Technology: The 58mm-diameter vacuum tubes feature a selective Al-N/Al-Cu coating that absorbs over 92% of solar radiation while minimizing heat loss (emission ratio <8%). This design ensures rapid water heating, even on cloudy days, thanks to infrared absorption capabilities.

Durable Construction: Made from borosilicate glass 3.3, the tubes resist hail impacts (up to 25mm diameter) and extreme temperatures (-30°C to 300°C), ensuring a lifespan of 15+ years.


Smart Pump Station (SR881)

Energy-Efficient Operation: The SR881 consumes <3W of power and includes temperature differential control to activate pumps only when needed, optimizing energy use.

Comprehensive Safety Features: Built-in frost protection, overpressure relief, and anti-legionella functions ensure safe operation in all climates.

User-Friendly Interface: The intuitive controller allows manual adjustments, holiday mode, and real-time temperature monitoring via digital display.


Large-Capacity Storage Tanks

Stainless Steel Durability: Tanks are constructed from food-grade SS304L stainless steel with PUF insulation, reducing heat loss by 90% and maintaining water temperature for extended periods.

Scalable Sizes: Choose from 150L to 1000L capacities to suit households, hotels, schools, or industrial facilities.


Pressure Management with Expansion Vessels

Membrane Design: The expansion vessels feature a dual-layer diaphragm to isolate water from air, preventing corrosion and ensuring stable pressure under thermal expansion.

Wide Temperature Range: Rated for 130°C and 10 bar pressure, they protect the system from damage during extreme heat cycles.


Applications


Residential Use

Home Heating: Ideal for family homes, providing hot water for showers, kitchens, and central heating systems. The RNE-SPHS-150 (150L) suits small households, while the RNE-SPHS-300 (300L) caters to larger families.

Energy Savings: Reduces water heating costs by 50–80% compared to electric/gas systems, with payback periods often under 5 years.


Commercial & Industrial

Hospitality Sector: Hotels and resorts benefit from the RNE-SPHS-1000 (1000L) to meet high-demand hot water needs for pools, spas, and guest facilities.

Institutional Buildings: Schools, hospitals, and offices use the system to align with sustainability goals, lowering carbon footprints while ensuring reliable hot water supply.


Agricultural & Off-Grid

Greenhouses and Farms: Efficiently heats water for crop irrigation, livestock, and processing, even in remote areas without grid access.
