Closed-Circuit Cooling Tower Freeze Prevention Notice

To Our Esteemed Customer:

When the winter freeze-up period begins, users of equipment—especially those using closed-circuit cooling towers—must take antifreeze measures to prevent the coolant inside the equipment from freezing and cracking the radiators, which could cause you unnecessary trouble.

Temperatures below 0℃ often cause the unit's water system to freeze, damaging the unit.

The following different antifreeze methods, Shandong Kanda Electric Furnace We recommend that you make a reasonable choice.

1. Keep the water pump. Operates 24 hours a day, keeping the cooling water inside the equipment flowing continuously to prevent freezing.

2. The control device maintains the water temperature above a certain value and prevents freezing by installing dedicated electric heating devices and an automatic water temperature control system on the water system pipelines.

3, When the equipment is shut down for winter, drain all water from the system. To do this, open the drain valves on the water system piping and also open the drain plugs at the bottom of the containers. To put Drain the water. ( Pay special attention to cooling tower radiators, reactors, and ultrasonic transformers. )；

4. Add antifreeze glycol to the water supply system piping in the appropriate proportion. ( Prohibition of the use of alcohol-based flammable products.

Our company provides the following data; specific additions are as follows: quantity You may consult the antifreeze supplier based on local temperature conditions and add antifreeze accordingly (we recommend that you store the antifreeze you’ve purchased in a safe place). Place Experimenting in the freezer Find the experience points. The amount of water in the circulating water tank doesn't need to be excessive—just enough to allow for circulation—to minimize the use of antifreeze.

Ethylene Alcohol Precautions for Using Type Cooling Fluid Item ：

1. When adding ethylene glycol-based coolant, avoid spilling the coolant onto the surface of the equipment to prevent corrosion of the equipment’s paint finish.
2. Ethylene glycol is toxic. When adding it, do not suck it into your mouth, and avoid getting it on your skin. If it accidentally gets on your skin, immediately rinse it off with plenty of clean water. Clean.
3. Ethylene glycol has a relatively high boiling point, and during the operation of the coolant, what mainly evaporates is water. If you notice that the water level is low, be sure to add more promptly.
4. For closed-loop cooling systems ， Generally used for corrosion and freeze protection. agent The coolant should not be filled to the brim; fill it up to... Use 70%-80% as the guideline to prevent overflow and subsequent expansion and leakage.
5. Before topping up, first flush the cooling system with water. After flushing, drain all the water completely before adding the coolant.
6. The mixing ratio of water to ethylene glycol should be adjusted appropriately according to the temperature in different regions. Generally, when preparing the mixture, its freezing point should be lower than the temperature of the region where the equipment will be used. 5 °C⁻¹ 0° C As appropriate, see the table above.
7. To prevent corrosion of the cooling system, antifreeze containing ethylene glycol should be added. agent Add to the coolant 1.6% borax, 0.35% of... Hydrogen Oxidation Sodium And's 2% Benzoic acid Sodium Ensures rust and corrosion resistance.
8. When the weather turns warmer, Must Drain the ethylene glycol-based coolant. Generally, if antifreeze is stored for too long, its corrosiveness will increase. It is recommended that... Replace it every year to ensure antifreeze performance. fruit 。

The above content is for reference only; for detailed usage, please refer to Yi Er. Alcohol Refer to the coolant instruction manual or consult the antifreeze manufacturer.

Also: When the temperature... -5° C The following spray Pump When shutting down, please drain the spray water completely and remove the water from the spray pump. Ranking Empty.

5 Other small tips:

Add a thermal cover to the outside of the device, and add three to four inside. 100 W The above electric heating tubes provide heat and insulation, ensuring the internal temperature of the equipment. High Yu 5° C ;

Note: Before starting the equipment, please check whether there is any ice formation inside the equipment and in the cooling water tank. Ensure that the cooling water flow is unobstructed. Start Movable equipment! No then It will cause severe damage to the device components. !

Friendly reminder:

If the water-cooled host is installed in a cool, well-ventilated area, even though the equipment... Working continuously for 24 hours, the coil of the water-cooled host could potentially freeze and crack, so it’s necessary to add an appropriate amount of antifreeze. quantity Ethylene diol Alcohol 。

Due to our company’s tight production schedule at the end of this year and the extended turnaround time for maintenance work, if water-cooling repairs become necessary, we may not be able to arrange them in a timely manner. The estimated turnaround time is approximately... 30-40 Heaven! Please be sure to take adequate frost-prevention measures so as not to disrupt your production.

The primary causes of freeze-related failures in water-cooling equipment over the years have been attributed to a sense of complacency on the part of the user organizations and inadequate management. Upon receipt of this letter, we kindly request that your company’s relevant leaders promptly take action based on local weather conditions. Warm Adopt reasonable antifreeze measures based on your company’s actual conditions.
