Product name Manufacturer
1 DESLIME MITSUBISHI GAS CHEMICAL. 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.
(4) Antifreezing solution
If the chiller is used in a cold district, it should be provided with
an antifreezing function. When the air temperature falls, the
water supply pump should be kept running. In a very cold district,
incorporate a heater into the chiller to prevent the water
temperature to drop too much. A chiller with a built-in heater is
recommended because the water temperature must reach 20°C or
greater to start the oscillator.
If it is necessary to use an antifreezing solution for lack of an
alternative, he following antifreezing solution should be used. Its
concentration should be 30% (usually) or 40% (in an extremely
cold district). Use of an antifreezing solution should be restricted
within four months in winter. The following antifreezing
solution is already added with an anticorrosive; do not use the
above-mentioned anticorrosive.
