1.2 COOLING WATER
Use either pure water or tap water treated in an ion exchanger.
Set the water temperature in the range from 20°C to 30°C.
Wait for the water temperature to reach 20°C or greater before
starting the oscillator.
(1) pure water supply unit
Install a pure water supply unit (ion-exchange region) at the
water inlet of the chiller. The pure water supply unit can prevent
problems with the oscillator from occurring due to corrosion or a
clogged pipe. Replace the water periodically after every 1,500
hours because the quality of the circulating cooling water is
lowered.
Product name:
Pure Water Treatment Cartridge
Manufacturer:
ORUGANO Corporation
Use:
Refer to the description indicated on the product.
(2) Anticorrosive
Add the following anticorrosive to cooling water immediately
after installation to prevent problems due to corroding cooling
water and to decrease the frequency of replacement of cooling
water.
Consult the chiller manufacturer for use of the anticorrosive.
Product name Manufacturer
1 CONTLIME K-6000 MITSUBISHI GAS CHEMICAL. Inc
2 Kurilex L-111 Kurita Water Industries LTD.
Use :
Add the anticorrosive to cooling water in concentration of
1000 to 2000 ppm (100 to 200 cc/100 liters). Monthly
check the concentration of the anticorrosive using
concentration check paper dedicated to anticorrosives 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 (manufactured by Mitsubishi Gas Chemical Inc).
