Details

The problem - Calcium creates scale in pipes,on appliances and other plumbing surfaces. This leads to higher heating and energy costs and expensive repairs to appliances,such as ice machines, coffee makers,dishwashers and cooling towers in commercial buildings. Scale can also be a source for bacteria to grow, which can be a health concern in drinking water applications. Calcium, on the other hand, is important to human health, and supplements are recommended if Calcium is reduced or totally void in one's diet.

The solution - WATTS®Anti-Scale systems transform Calcium ions into Calcium crystals, which are stable and cannot attach to pipes, surfaces, hardware or heat exchanger components. The crystals are so small they are easily rinsed away by the water flow.

Benefits

  • Scale is virtually eliminated!
  • Aids in removing existing scale.
  • No costly repairs to appliances due to scale.
  • No salt
  • No brine tank.
  • No backwash.
  • Saves water!
  • No electricity.
  • Easy installation.

ScaleNet® is an environmentally friendly alternative to water softening or any other treatment device designed to address limescale for the entire house. ScaleNet® prevents scale by transforming dissolved hardness minerals into harmless, inactive microscopic crystal particles. These crystals stay suspended in the water and have a greatly reduced ability to react negatively and form scale compared to untreated hard water. Physical Water Treatment devices for Scale Prevention and achieved an efficiency rating of 99.6% for scale prevention ScaleNet® media has been tested and certified for material safety to NSF/ANSI Standard 42 and 61 Limitations to use - 428 ppm hardness, no Fe, Mn or HS, <3ppm Cl (if in doubt please ask as it is possible to either treat the problem or re-size the unit as necessary) Install systems in new facilities with copper pipework after one month of water use ScaleNet® systems will leave white deposits on shower curtains etc, but are easily wiped away We are also able to offer commercial models with higher flow rates, but would need to price these on an individual basis

 

 

Installation & Maintenance: we offer our own installation and maintenance service via our national network of approved plumbers. The service is offered subject to availability (dependent on how remote your location is).

How does ScaleNet® differ from a Water Softener?

ScaleNet® uses a specially designed media to convert the dissolved primary hardness mineral (calcium carbonate) into a relatively insoluble microscopic crystal so that it cannot cause harm downstream. A water softener, on the other hand, uses the principles of “ion exchange” to remove calcium and magnesium ions from water while
replacing them with sodium ions. A water softener requires a control valve, backwashing, drain line, regeneration and a brine tank to store salt while ScaleNet®
requires nothing but an inlet and outlet connection.

Does ScaleNet® remove the important minerals in water?

No. ScaleNet® preserves the beneficial mineral content while preventing the possible negative scale formation associated with these minerals. By rendering the hardness minerals harmless while still keeping them present, you truly get the best of both worlds. Other treatment methods fall short.

In a 2005 report on Nutrients in Drinking Water, the World Health Organization
writes…“We conclude that hard water is good because it contains nutrients valuable in themselves…To minimize heart disease risk, the ideal water should
contain sufficient calcium and magnesium to be moderately hard.”

Applications for ScaleNet®

Virtually any application where scale reduction or scale removal from water hardness is required or desirable. For humidifiers, distillers, steam generators,
solar heating systems, tankless water heaters, RO pre-treatment, misting systems, tract home builders, laundromats and numerous food service applications are all ideal for a ScaleNet® system.

What factors may effect ScaleNet’s system performance?

Water chemistry and peak flow rate are the guidelines used to assure optimal system performance. Most municipally treated (city) water falls well within our performance guidelines to ensure scale control results. However, there are chemistry limitations related to possible foulants and interference ions. Water known to contain visible dirt and debris must be strained using a wye-pattern strainer or equivalent (100 mesh) before ScaleNet® tank systems.

As with any water treatment technology, correct sizing of the system is important to ensure proper performance. However, ScaleNet® is more forgiving of flow variations and
unplanned peaks than a conventional water softener.

Does the media in a ScaleNet® System need to be replaced?

Yes. Tank-based systems require media replacement every three years. Systems should be installed with this in mind. An isolation valve with a by-pass loop is
recommended for most commercial applications so the tank(s) can be taken off-line for media replacement. Filter housing based systems require cartridge
every year.

Are there any application limitations to ScaleNet®?

Untreated well water may pose a limitation to ScaleNet® due to the unknown chemistry it often possesses. High hardness is never a problem for ScaleNet®, but with well water, hardness minerals are often accompanied by other contaminants with levels outside of our operating guidelines. Additionally, closed-loop systems that do not offer a
“blow-down” or “flush valve” are not recommended because the micro-crystals need to exit the system.

How easy is it to install a ScaleNet® system?

For anyone who has ever installed a Water Pressure Reducing Valve or a Backflow Preventer, installation of a ScaleNet® system will be relatively easy.
Tank systems offer “sweat” or “plastic MPT” connection sizes in 3/4", 1" & 1-1/4". Larger tanks offer single socket or manifold connections in 2" sizes. Several
ScaleNet® installation accessories are offered to accommodate most applications. ScaleNet® systems are compact allowing for easy installation when space is limited. ScaleNet’s light weight makes it easy for the installer to transport with nothing more than a hand truck.

What are the on-going maintenance costs and considerations for ScaleNet®?

One of the great benefits of the ScaleNet® technology is the dramatically reduced maintenance requirements. Other than the planned media replacement, there is nothing else required. For tank systems, the media replacement is once every three years, and for filter housing systems, it's once a
year. That's it.

Why is ScaleNet® a “Green Technology”?
ScaleNet® is truly a “Green product” because it saves water and energy in the following ways:
1. Reduces Energy Consumption – ScaleNet® uses no electricity and reduces energy consumption by keeping heat transfer surfaces free of energy-robbing scale formation.
2. Reduces Chemical or Raw Material® Consumption – ScaleNet® requires no chemical or significant ongoing consumable (salt, as an example)
3. Reduces Waste Water Discharge and Water Consumption – Because ScaleNet® does not discharge or require backwashing it meets both objectives.
4. Reduces Space Requirements – ScaleNet® systems use approximately 75% less floor space than water softeners.
5. Retains nature's minerals in the water. The beneficial minerals, calcium & magnesium, are completely retained.

Installation Instructions:

The flow thru the Scale Net™ system is upward. Therefore, the inlet and outlet connections are opposite of traditional water treatment equipment. The flow rate must not exceed the maximum specified flow rate of the system. A flow control devise
will be required for applications where flow rates may exceed the maximum specified flow rate.

1. Place system on a smooth flat surface.
2. Install the fittings and / or the bypass (see separate instructions). Slide the
nut on first then the split ring and o-ring.
3. Connect incoming cold water to the inlet of the system.
4. Connect system outlet to service water of the house.
5. Partially open a valve down stream of the system to allow the air to purge
from the system.
6. Slowly open inlet valve and allow the system to fill with water.
7. Close the down stream valve five minutes after all the air has been purged
from the system and plumbing. This flushes any fines out of the system.
8. Check for leaks and repair as required.
9. System is ready for use.

Conditions for Operation:
• Minimum pressure 15 PSI
• Maximum pressure 125 PSI
• Minimum operating temperature 34 F
• Maximum operating temperature 120 F
