Take control of limescale with proven commercial water conditioner and maximise system efficiency with Rinnai commercial water heaters
The Rinnai Nexus is a uniquely-powered water conditioner for commercial hot water systems. Independently tested, it is a low-maintenance and simple installation way to protect a property against the damaging and expensive impact of limescale buildup.
- Long lasting protection against water issues such as the formation of hard limescale
- Ensure bacteria has fewer places to hide as a result of cleaner surfaces improving water quality
- Protects capital investment
- Protects system equipment such as shower heads.
- Independently tested and proven
- WRAS approved for drinking water
- Permanent treatment of water
- Used and specified in all market sectors
The water conditioner is widely specified and installed in a range of sectors such as manufacturing, hotels, retail and supermarkets, healthcare and education as well as public authorities.
Proven Performance in Reducing Scale Buildup & Delivering Value Engineering
The electrolytic zinc anode technology used is listed in the UK Building Regulations - Part L Building Services Compliance Guide, whereas "external to pipe" water conditioning techniques are not referenced.
The low level of zinc additions made by this water conditioner changes the water conditions and inhibits the formation of limescale by transforming calcium carbonate crystals in such a way that they do not stick.
Delivering Value Engineering
The zinc treatment process of the Nexus water treatment system does not decay after dosing and its effectiveness is not impacted by water storage or agitation caused by passing through a booster set which ensures consistent performance. The system has a simple installation process and can be installed in the rising main, before the water heater and booster set.
Capital expenditure savings are probable because the rising main pipe size is often a smaller diameter than the hot and cold water supply pipe sizes. As our treatment does not decay, we only need to install one system to treat the whole location, offering an attractive value engineering opportunity.
The nexus is a chemical and electricity free, fully recyclable water treatment system enabling both end users and water treatment providers to tackle the problems of limescale without impacting the environment.
Reduce Environmental Impact
With commercial water softeners 1,000kg of salt has to be mined, cleaned, transported and then ultimately put into the local rivers or directly into the sea. This makes commercial water softeners not as environmentally sound as a high performing commercial water conditioner.
Save Money & Breakdowns
Due to the fact that around 60% of the mains water supplied in the UK is classified as ‘hard’, limescale build up on heat transfer surfaces, internal pipework surfaces, shower heads and other components create costly and unhygienic problems.
Limescale deposits reduce the efficiency of water-heating appliances, shower pressure and wider water supply fittings, increasing running costs and potentially harbouring bacteria on all types of outlets such as different shower types and tap water outlets
Impact of water hardness content in water
British Water calculates that every 1.6mm or 1/16” of scale buildup in a heating system causes a 12% loss in heating efficiency.
The Carbon Trust also found: “A 1mm layer of limescale will cause a 7% increase in energy input to the boiler to meet the same heat demand”
Commercial Water Conditioning vs Water Softening (Salt Softeners)
Commercial water softeners replace calcium & magnesium ions with sodium ions (salt) to soften the water. This can cause pitting and pinhole corrosion within water systems.
The Nexus solution has been independently tested and proven to reduce limescale in water systems, offering savings of up to 55% of energy costs.
Payback can be very fast, due to the wide spectrum of savings in chemical remedial work and costs associated with water heating. In addition, appliances last longer.
Rinnai Nexus is a patented galvanic and electrolytic solution in a self-cleaning package. In this process, minute amounts of high-purity zinc ions are released and react with calcite. Calcite crystals are modified into adhesion-neutral aragonite, which is simply discharged into the water.
Different to other water treatment units such as water filters is that the Rinnai Nexus operates without current, chemicals or magnets. The two swirling chambers each upstream and downstream agitates the water and is responsible for the self-cleaning units themselves.
