DE-IONIZED & DE-MINERALIZED WATER:
Pure Water for Industrial & Automotive Applications:
Diesel Generators New Zealand manufacture highly purified PH neutral de-ionized (DI) water for industrial applications. Our Water is filtered on our premises using the latest technology and the following process:
- Stage 1 - 20 Micron pre filter media.
- Stage 2 - 5 Micron pre filter carbon media.
- Stage 3 - 1 Micron pre filter media.
- Stage 4 - Ultraviolet sterilization.
- Stage 5 - Reverse osmosis filtering (RO).
- Stage 6 - Quad mixed bed ion exchange resin filtering.
- Stage 7 - 5 Micron post filter media.
- Stage 8 - 1 Micron post filter media.
- Stage 9 - PH, C-Ion, A-Ion and suspended particle testing. (We do not test bacterial count).
De-ionized Water is used in the following applications:
- Automotive cooling systems.
- Industrial cooling systems.
- Generator cooling systems.
- Lead acid batteries (cars, trucks, boats, forklifts etc).
- Industrial steam systems.
- Non residue applications such as window cleaning, pressure washing etc.
Our main use of DI Water is for automotive and generator applications. Council tap, rain tank and well water contain minerals and chemicals which are corrosive to the metal components found in engines cooling systems and form scale over a period of time. Since DI water is free of any particles, it is safe to use in cooling systems and will prevent corrosion and hard deposit obstructions.
The same can be said of lead acid batteries found in automotive, industrial and marine installations. Filling and topping up with DI Water is essential to maximize the lifespan of batteries as it does not contain minerals that will corrode or build up on the internal metal components.
Water is sold in high strength 20 litre plastic drums and can be couriered nationally (Non DG).
Drums all come with a bung to accommodate an optional Valve for easy dispensing of smaller quantities.
Higher volumes in 200 Litre drums or 1000 Litre Intermediate Bulk Containers (IBC's) can be supplied on request (we only supply new containers).
A container exchange service is available to reduce costs (conditions apply).
MSDS supplied.
We recommend Ezi-action Drum Pumps http://www.nzpump.com/
CAN I USE RAIN WATER?
No. Rainwater gets its composition largely by dissolving particulate materials in the atmosphere when droplets of water nucleate on atmospheric particulates, and secondarily by dissolving gasses from the atmosphere. Rainwater compositions vary geographically and can contain quantities of Salt plus CO2 and gaseous acids (SO3, NO2) and bases (NH3).
CAN I USE BOILED WATER?
No. Boiling does not remove any of the water's ion or chemical content. The Steam has to be condensed and the associated cooled water collected to be free from dissolved minerals and Ion's.
OTHER USEFUL INFORMATION:
Deionized Water is a very "hungry" acid, however, it's hunger is very easily satisfied. DI Water fresh from a DI Column will easily be >15 MΩ resistivity.
Once exposed to air, DI water will quickly absorb CO2, satisfying its acidity and reducing its resistivity very quickly. Once it leaves the system, it very quickly drops down to approximately 1 MΩ which is typical. It is also true that it will lose resistivity the moment it comes in contact with any container due to any inherent contaminants. This is particularly noticeable in plastic, low grade stainless steel or ferrous metal containers. Good quality, sealed, glass containers are best.
