SOME SUCCES CASES
IN MEXICALI
CATTLE SLAUGTHER HOUSE BOILERS
Installation of two SB 200’s in the discharge of the boiler make-up tank. Results were elimination of 100% of the chemical
treatment, reduction in the temperature of the chimney fume, and 30% less bleed off. We also installed 1 SB 200 in the make
up of the cooling tower and 2 SB 300’s in the recirculation line of the ammonia coil cooling tower. Results were elimination of
100% of the antifouling chemical and reduction of the bleed off of the towers by 30%. Return on investment for the project was 6
months for the boilers and 14 months for the cooling towers.
Scale blaster keep the towers and boiler clean and free of fouling , the sb-200 clean the excess of calcium carbonate in 60 days
through the bleed off and manual process as you can see in the pictures
Inspection port of the boilers
You can see in the pictures how the scale blaster started to clean the
boiler tubes through the inspection ports.
Here you can see the inspection ports with
soft, easy to remove scale. After only 30
days, the boiler tubes are almost clean.
CERRO PRIETO (CFE)
GEOTHERMAL
After almost five years testing in different geothermal steam wells, we obtained the approval of
CFE to install several units including SB600, SB1400 and SB2000. Geothermal applications
are not easy because of the chemistry of the wells, different temperatures, and different
pressures. In every case it is necessary to have the well water chemistry in order to select the
correct unit . We obtained very good results in the production orifice, the separator and the
condensate lines.
You can see in the picture the fouling factor of the well. Depending the pressure and temperature,
one inch of thickness for every 15 days. Scale contains calcium carbonate, magnesium and three
types of silica.
Some of the lines contained hard brine with a high level of fouling.
In every case, specific scale blaster equipment was installed in the
geothermal wells with successful results. More than 50 units of
different sizes were installed.
PLAZA NUEVO MEXICALI
Complete chilled water plant
treatment included 3 Carrier screw
chillers of 300 tons each, 3 BAC
cooling towers, and an ITT pumping
system. Installation of 1 SB200 in the
make up of the tower, 3 SB600’s one
per chiller, one silver copper unit and
sand filters. Project cost $45,000
with pay back in 3 years. Chemical
treatment was eliminated with a 30%
water bleed off reduction.
Keeping the tower fill clean, the combination of
scale blaster, silver copper unit ( biological control),
sand filter ( suspended solids), and an automatic
bleed off system keeping 5000 micro siemens total
dissolved solids in the water with a pH of 7.8 to
8.2, maintained the chemistry control of the water.
PILKINGTON
Installation of 2 SB200’s for boilers, 1 SB200
for reverse osmosis plant, and 6 SB125’s for
evaporative coolers. Pilkington is a car
windshield glass production plant. Project
return on investment 14 months. Reduction
of boiler chemicals by 50% due to the
company policy they have to use chemicals
in the boilers. No fouling in the tubes or
sump of the evaporative coolers. Results in
the reverse osmosis unit showed less
membrane changes per period .
CHILLERS TRANE CENTRIFUGAL
Installation of 1 SB200 for
tower make-up, 2
SB600’s 1 per chiller, no
silver copper unit as they
use chemical control for
biological growth, and
sand filters for suspended
solids. Payback 12
months.
BENQ
The lay out shows the
installation of scale blaster
in the main row of the
building taking advantage
of the benefit of the scale
blaster for bathrooms,
landscaping and other
uses. We also installed
monitoring equipment for
chemistry control.
