70 Ton Chiller – Water Chiller Manufacturer


How to maintain the 70 ton chiller daily?

1. Routine inspection

Every other week, it is necessary to check whether the water level of the 70 ton chiller meets the requirements, and check whether the water quality of the chiller has changed (color, smell, impurities, etc.) once a month. Followed by regular replacement and cleaning, you can refer to the following replacement and cleaning cycle.

2. Filter cleaning cycle

According to the water quality, check once a week whether the filter is clogged (laser water inlet filter, water cooler filter), the laser water inlet filter is in the Y-shaped laser water inlet, and the 70 ton chiller filter can be confirmed according to the equipment model The location is generally on the outlet pipe.

3. Dust filter cleaning cycle and cleaning steps

The dust filter is on both sides of the 70 ton chiller, and the dust filter is easy to remove. When there is a lot of dust, the frequency of cleaning can be increased. Remove the dust screen and use an air spray gun to remove the dust on the dust screen. For oily dirt, please clean it with a neutral detergent. Before reinstalling the dust screen, rinse and dry it.

4. Filter replacement cycle

Check whether the filter element of the 70 ton chiller is polluted, and the filter element needs to be replaced every six months at most (depending on the actual model, some have no filter element).

5. Cooling water replacement cycle

Replace the cooling water according to the water quality, and the cooling water needs to be replaced once every 3 months at the longest. The water tank of the 70 ton chiller is not sealed. It is exposed to dust for a long time. Dust, metal shavings and bacteria enter the cold water and cause the water to deteriorate. Substances that do not dissolve water are produced and adhere to the inner wall of the laser waterway, thereby blocking the waterway and causing water leakage. The flow rate drops, reducing the cooling effect. If this happens, drain all the deteriorated cooling water in time and replace it with new cooling water.
