Cooling system descaler and scale
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. You can view the product MSDS and informative product

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
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

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.

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.

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
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
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.
