Product Features:

The PH value is 1; although the acid is strong, it is safe for the material.

The descaling and descaling effect is good, the use is safe and the operation is convenient.

Economical-can be diluted 10 times with water.

After cleaning, it can quickly and effectively improve the cooling effect of the central air conditioner.

Scope of application:

Scale cleaning of central air-conditioning water systems in industrial and mining enterprises, hotels, hotels, shopping malls, office buildings, office buildings, etc.

Instructions:

Circulating cleaning method: The ratio of this product to the circulating fluid is fed from 1:10 to 1:20, and the specific amount depends on the fouling situation. After feeding, soak for one hour, and recirculate for cleaning for about 3 to 6 hours, and pay attention to keep the acidity of the circulating fluid at PH value 1. After the cycle is completed, drain the cleaning fluid, circulate with clean water, and then use QR-124 neutralizer or prepare your own The lye will neutralize the remaining acid until the PH value of the inlet and outlet water is consistent; the ratio of neutralization with soda ash: 1‰～3‰. [In order to save cleaning costs, we recommend that the main unit (condenser or heat exchanger) be cleaned with 10 times diluent, and then connected to the entire system for cyclic cleaning for 3 to 6 hours (replenishing 1% of the original liquid), and then drain the waste liquid or pump Go to the next air-conditioning system; finally use QR-124 neutralizer for neutralization and passivation.

Spray or soak the removed air-conditioning fins with QR-555 diluted with water 1-2 times (depending on the degree of fouling), and rinse with water after the reaction is complete.

Precautions:

This product is acidic, please do not touch the skin for a long time

 After pickling, it must be neutralized and passivated in time
