Cooling Tower Descaler and Scale Cleaner:

 

Micro-Nice D-5

Cooling system descaler and scale preventative chemical

 

 

Micro-Nice D-5 is a non-toxic botanical extract used to remove scale and scum from cooling and heating systems. D-5 uses plant extracts to penetrate between existing scale on interior surfaces while preventing new scale from forming.

The Problem:

Water typically contains common salts such as calcium carbonate and magnesium carbonate, which are unusually less soluble in hot water than they are in cold water. This leads to rock hard deposits where heated water is introduced to these salts. Calcium from hard water also combines with soaps that would normally dissolve in water, which forms scum that precipitates out in a thin film on the interior surfaces of heating and cooling systems.

The formation of these deposits can drastically reduce the efficiency of the system. By looking at the graph below, you can see that even a mere 3/32" of scale can decrease the efficiency of the system by 50%!

The typical method of removing this scale and scum is to use acids, such as hydrochloric or sulfuric acids. These acids are applied to the scale-inhabited system in an effort to dissolve and remove the scale. However, the use of acids can actually create additional salts which can turn into further scale. The following is the chemical reaction between calcium carbonate (CaCO3) and hydrochloric acid (HCl):

1 CaCO 3 (s) + 2 HCl (aq) = 1 CaCl 2 (aq) + 1 CO 2 (g) + 1 H 2 O (l)

As you can see, the reaction has produced another soluble salt, CaCl 2 (calcium chloride), which increases the potential for further scale formation.

Aside from the chemical aspects of using acids as descalers, there is also the health and environmental aspect of using acids. It is commonly known that acids, such as hydrochloric acid and sulfuric acid, are extremely corrosive and hazardous to living beings. Their chemical reactivity can prove to be potentially fatal, citing the example of the mixing of hydrochloric acid with common household bleach which will produce toxic chlorine gas. Sulfuric acid has been documented to cause more serious burns to the skin due to it's dehydrating properties. If these acids are released into storm sewers, they can be detrimental to aquatic plant life and animals.

The solution: Micro-Nice D-5

As opposed to the use of acids, Micro-Nice D-5 uses a physical reaction to reduce the inter-molecular bond between the scale and the surface to which the scale has adhered. Since no acids are being introduced, there is no further development of additional salts. Micro-Nice D-5 reduces the surface tension and static electricity of salts and scum, making existing scale fall of of the system's surfaces while simultaneously preventing new scale from forming.

Micro-Nice D-5 is completely safe for the system, with excellent corrosion test results on stainless steel, aluminum, zinc, and copper. Click here to view the corrosion test results from tests performed by Mtec Technical Services in Bangkok, Thailand.

Micro-Nice D-5 is also friendly to the user and to the environment. The active ingredient is comprised of a natural botanical phytochemical, and the use of Micro-Nice? D-5 requires no special handling measures. Click here to view the biodegradability test results of Micro-Nice D-5 from tests performed by the Department of Science Services in Bangkok, Thailand.

Micro-Nice D-5 Case Study performed in the United States:

Over the course of a 60 day period in early 2007, Technogreen USA had the opportunity to run a large-scale evaluation of Micro-Nice D-5 domestically in the United States. Click here to view the white parpers of this case study at an Ultra High Temperature dairy facility in Virginia.

Micro-Nice D-5 Case Studies in Asia:

There are several companies in Asia using Micro-Nice D-5 as their scale and scum control chemical. The following are a couple of case studies on two specific customers in Thailand:

Central Department Store Group cooling tower study using Micro-Nice D-5

Walls Ice Cream factory energy savings study using Micro-Nice D-5

Directions For Use:

A concentration of 250 to 500 ppm is recommended for effective system cleansing. Add Micro-Nice D-5 in one of the following dilutions:

  • Add 1 liter of Micro-Nice D-5 for every 2,000 to 4,000 liters of water

  • Add 1 liter of Micro-Nice D-5 for every 528 to 1,056 gallons of water

Q: How do I determine how much Micro-Nice D-5 to add to my cooling tower water?

A: Micro-Nice D-5 is recommended at 250 to 500 ppm as a cooling tower water treatment to remove and control scum and scale build-up. We have created a calculator for your use to calculate how much Micro-Nice D-5 to initially add to the system, and also how much D-5 needs to be added as a result of the addition of make-up water.
