CALFA BAS is New Generation Water Treatment for cooling tower-cooling system-water chiller to save Water and Energy
 
"CALFA BAS" is water treatment preparation friendly to the Environment, and which Conditioner for the circular cooling system accorded in the ISO14001. "CALFA BAS" is an inorganic product, economical, safe and easy to handle with remarkable effects, replacing the management of the circular cooling water by organic compound chemicals.

TEST.A
The test was done at "M" electric parts factory in Japan, below pictures are corrosion progress test that have been
immersed 2 iron plates and 2 copper plates in the cooling towers for 49days. As you can see, The sample plates which supplied CALFA BAS water did not corrode beside only circulated or supplying water.

TEST.B
 TEST: Corrosion Test (metal material: The sample plate (*AC4C, 50mmx30mmx3mm) ) *AC - A:Alminium C:Casting

Test method:
1. Measuring the weight(mass) of sample plates after ultrasonic washing for 5 minutes in acetone and drying.

2. After measuring the weight(mass), 4 sample plates are attached to a machine (*accorded in JIS K 0100 reference), and immersed in 5 litters of Sample Water which kept temperature at 40 degrees Celsius , and revolving for 14 days each.
(Revolving speed : 220-240rpm)

(The quantity moisture evaporated from sample waters while operating, Supplies distilled water)

3. Ultrasonic washing for 15 minutes in acetone, remove the part of corrosion in Nitric Acid (4+1) for 20 min.,
Then, Ultrasonic washing for 5 minutes in acetone again.

4. Measuring the weight(mass) after drying, find out how much weight(mass) was lost by corrosion on average.

Test Result :
 "Supply Water with CALFA BAS" did not lose the weight(mass) the most by corrosion.
CALFA BAS can also prevent the corrosion against "ALUMINIUM Materials". On the other hand, The Anti-corrosion Chemical was used for Aluminum, the corrosive rate was promoted conversely.

TEST.C
 TEST: Corrosion Test (metal material: The sample plate (*SPCC, 50mmx30mmx1mm))
*SPCC - S:Steel P:Plate C:Cold C:Commercial

Test method:
1. Measuring the weight(mass) of sample plates after ultrasonic washing for 5 minutes in acetone 2 times and drying.

2. After measuring the weight(mass), 4 sample plates are attached to a machine (*accorded in JIS K 0100 reference), and immersed in 5 litters of Sample Waters which kept temperature at 40 degrees Celsius, and revolving for 14 days each.
(Revolving speed : 220-240rpm)

(The quantity moisture evaporated from sample water while operating, Supplies distilled water)

3. Ultrasonic washing for 15 minutes in acetone, immersed in 20wt% of sodium hydroxide solution (70 degrees Celsius ) for 50 min. and gives Ultrasonic for more 10 min.

4. After washing by water, remove the part of corrosion in 20wt% of citrate hydrogen 2-ammonium (70 degrees Celsius ) for 60 min.

5. After washing by water, ultrasonic washing for 5 minutes in acetone, Measuring the weight(mass) after drying, find out how much weight(mass) was lost by corrosion on average.

Test Result :
 "Supply Water with CALFA BAS" did not lose the weight(mass) the most by corrosion.
CALFA BAS can also prevent the corrosion against "STEEL Materials" more than twice compares with the Anti-corrosion chemicals which a major Japanese chemical company produced.

TEST.D

Below pictures are corrosion progress test that have been immersed 2 CHROMIUM STEEL plates into water. Left Picture is "Chromium Steel Plates + Tap water that BAS immersed", and Right Picture is "Chromium Steel Plates + Soft water that exchanged ION (Na type)" Chromium steel is one of the steel which is the easiest to corrode in water even if only 1 hour.

   
   
TEST.E

Below pictures are corrosion progress test that have been immersed 2 CUTTING EDGEs into water. Left Picture is "cutting edges + Tap water that BAS immersed", and Right Picture is "cutting edge + Tap water". and 1 week later.
The cutting edges of box cutter (mixed metal) are simple material which somebody available in the market place.

   
          (1 Week Later)          
   
 
[CONCLUTION] :
Reverse Osmosis-treated water (RO water) is not harmful to the human health, and for Environmental. Ofcourse NO SCALE formations. However, what about RO water in metal piping, heat exchangers, cooling towers? 　RO water easy to corrode these metal equipments. CALFA BAS is "VALUABLE" as an Corrosion Inhibitor for those cooling systems.
