Do you know how to maintain an air cooled water chiller in winter? Winter chiller operation requires antifreeze measures to ensure stability. Following these water chiller guidelines can help you prevent freezing and safeguard your water chiller in cold conditions.
Winter chiller operation requires antifreeze measures to ensure stability. Following these guidelines can help you prevent freezing and safeguard your water chiller in cold conditions.
When the Temperature Is Below 0℃, Add Antifreeze: Antifreeze can lower the freezing point of the circulating water, preventing freezing and cracking of pipes and ensuring the sealing of the pipes. Therefore, when the temperature is below 0℃, promptly add antifreeze.
Antifreeze Mixing Ratio: To ensure the normal operation of the laser chiller, strictly control the ratio of antifreeze to water. The recommended ratio is 3:7.
*Tip: It is advised not to exceed 30% for the added antifreeze ratio to prevent pipe blockage and accessories corrosion due to high concentration.
Water Chiller Running 24 Hours: Keep the laser chiller continuously running 24 hours when the ambient temperature is below -15℃ to ensure continuous water circulation and prevent freezing.
Regular Inspections: Periodically check the chiller's cooling system, including cooling water pipes and valves, for any leaks or blockages. Address issues promptly to ensure normal operation.
What Should You Keep In Mind When Not Using The Chiller In Winter?
1. Drainage: Before long-term shutdown, drain the chiller to prevent freezing. Open the bottom drainage valve to let out all the cooling water. Remove the water pipes and internally drain by opening the water fill port and the valve. Then use a compressed air gun to thoroughly dry the internal pipes.
Note: Avoid blowing air at the joints where yellow labels are pasted above or on the side of the water inlet and outlet, as it may cause damage.
2. Storage: After draining and drying, reseal the chiller. It's recommended to temporarily store the equipment in a place that doesn't affect production. For water chillers exposed to the outdoors, consider measures such as wrapping the chiller with insulating materials to minimize temperature reduction and prevent dust and airborne moisture from entering the cooler.
During winter chiller maintenance, focus on antifreeze fluid, regular inspections, and proper storage. For further assistance, feel free to consult our customer service team via [email protected]. For more about TEYU S&A water chiller maintenance, please click TEYU Chiller Case.
