RHOMBUS2 - Dental Reverse Osmosis System

RHOMBUS2 Dental Reverse Osmosis System

Ref: RHOMBUSSYS2

The new RHOMBUS2 system is an advanced reverse osmosis system, designed specifically as an alternative to a water distiller. With 5 stages of filtration the RHOMBUS2 will remove up to 99% of impurities from tap water. Due to its high specification, the RHOMBUS2 should not be compared directly with regular domestic reverse osmosis units available on the web. This unit, tailored for the dental sector and for autoclave water production features a post membrane demineralisation cartridge and integral TDS conductivity monitor to ensure consistent production of quality water. Distillers have a tendency to use lots of electricity and can have a short life span, whilst our dental RO systems are built to last for many years.


With over 20 years in the industry you can be reassured you are purchasing from experienced suppliers of reverse osmosis systems to the dental sector.

• Internal mains booster pump so the system works regardless of mains water pressure.
• Internal leak detector.
• Only £90 to maintain filters per year.
• Up to 100 litres of water per day.
• Less than 4p per litre.
• Improved membrane rejection rates.
• Smart looking external case.
• Certified NSF components.

With a RHOMBUS2 reverse osmosis system in place, you can rest assured that your surgery meets the full legislative standards with respect to the quality of water used.

RHOMBUS 2 QUESTIONS AND ANSWERS
Below is a list of questions that we are frequently asked by prospective and existing customers that we hope will be of use to you.

What is it?
The RHOMBUS2 is the result of product development in conjunction with feedback from distiller users who are looking for better suited ways of ensuring an adequate supply of purified water for use in autoclaves & washers / disinfectors. Based on standard reverse osmosis systems which remove up to 98% of impurities, the RHOMBUS2 takes this process one step further and removes 100% of impurities from UK mains water.

Is it easy to install?
In a nutshell – yes. The RHOMBUS2 arrives pretty much assembled and ready to install with minor attention required and some basic DIY actions, leaving you ready to use the system. If the user is not confident to carry out minor / basic DIY they should consult a suitably qualified handyman / plumber.

Is it a complicated process?
Although reverse osmosis can be tricky to explain to a user who's not familiar with technical jargon, it is a simple process to understand. The incoming water goes through 5 stages of filtration – which requires no actions on the part of the user. Install it – give it time to fill up – and then you will have purified water. Put simply, the system rejects impure water to drain, whilst storing purified water for use.

Does it require technical knowledge for maintenance?
Another short answer – no. When you need to change the first 3 filters (every 6 months at least), you isolate the supply to the system, close the tank, press the tap and wait a few seconds. Then you open the filter housing and change the internal cartridges. The same process is used on the membrane – but this is done every 2/3 years and the post cartridge is done every 2 to 3 months depending on use.

Is changing the filters hard to do?
Whilst it may seem daunting to carry out a filter change for the first time, there is practically nothing that can go wrong. The most common mistake is people forget to re-open a valve when the change is complete. So after one or two changes, you would soon know the difference between a shut off valve and a flow restrictor.

Is it expensive to run?
The average annual running cost of a RHOMBUS2 system over a 3 year period is on average between £80 and £130 depending on filter change frequency. Compared to a water distiller this is a huge saving as more water is available on tap.

How will I know to change the filters?
If you remember that the pre filters must be changed at least every 6 months and the membrane should be changed at least every 2-3 years, then the system will do the rest. The integral TDS meters tell you how the system is performing and when the read out on the final meter is above 000ppm – change the post cartridge.

What are the 5 stages of filtration & purification?
The first filter (sediment) is designed to remove sediment and any particles from your pipe work. The second 2 filters remove taste/odour inducing chemicals that can damage the membrane and affect the performance of the whole system. This stage will remove particles down to 10 microns, ensuring that the membrane is not blinded by contaminants or damaged by chemicals. The membrane will purify water down to 0.0009 microns, and the purified water goes to the storage tank whilst the impure water gets flushed to drain. When you open the faucet, the water then goes through the final stage of filtration – a bed of demineralising media where residual impurities are removed by the special mixed media. The membrane will remove up to 98% of impurities and providing correct monitoring of the system and TDS meters, any impurities that get through the membrane will not make it past the final stage of filtration.
