to 2000 ppm (100 to 200 cc/100 liters). Monthly check the
concentration of the anticorrosive using concentration check
paper dedicated to anticorrosive and add the anticorrosive to
cooling water until the concentration reaches about 1000 ppm.
Concentration check paper :
Purchase a concentration check set (50 sheets of check paper, a
dropping pipette, etc.) together with CONTLIME K-6000

CAUTION
If the above anticorrosive is added to cooling water
and the concentration is controlled, also be sure to
replace the cooling water every year.
3.2.2.5 Cleaning agent
To remove foreign matters such as fur that have adhered to the inside
of the cooling water circulating path, wash the cooling water
circulating path using the following detergent. Consult the chiller
manufacturer for use of the detergent.
Product name Manufacturer
1 DESLIME Mitsubishi Gas Chemical Company, Inc.
2 Kuridine I-302 Kurita Water Industries Ltd.
Use:
Add the detergent of 10% of the amount of cooling water,
circulate the water for an hour, then drain the water. After that,
rinse the cooling water circulating path thoroughly. Do not touch
a stock solution of DESLIME with your bare hands because the
solution is a strong chemical. If a stock solution accidentally
contacts your skin, wash the stock solution off your skin well
under running water.
If waste water used for washing is left standing, the main
ingredient, hydrogen peroxide is decomposed. Wait until
hydrogen peroxide is decomposed or dilute waste water with
water to reduce the concentration, then flush the waste water
down the drain.
