How to maintain high-frequency induction heating equipment in winter?
How to Maintain High-Frequency Induction Heating Equipment During Winter? Dear Yongda Cooling Equipment users, As strong cold air has recently swept in, causing a sharp drop in temperatures, we urge you to take proactive steps to protect your equipment. To prevent the cooling water inside your devices from freezing and potentially cracking the copper pipes—causing inconvenience—we recommend implementing effective frost-proofing measures. Drawing on years of experience serving our customers, Shenqiu Yongda Cooling Equipment Co., Ltd. has prepared this frost prevention guide for your convenience. If needed, feel free to reach out to us for further assistance. Here are some practical frost-proofing tips: 1. **Keep the water pump running 24/7** to ensure continuous circulation of cooling water within the system, effectively preventing it from freezing. 2. **Drain all water from the equipment**, paying special attention to components like the cooling tower radiator, reactors, and ultrasonic transformers. 3. **Add ethylene glycol-based antifreeze fluid** (note: never use alcohol-based or flammable products). Our company provides recommended guidelines below; however, the exact amount required should be determined based on local temperature conditions—consult with an antifreeze supplier for precise advice. As a general tip, add just enough antifreeze to ensure proper circulation while minimizing overall usage. *Important note:* Before adding antifreeze, test it by placing a small sample in your freezer to determine its optimal concentration for your specific climate. *Regarding the coolant tank:* There’s no need to fill it excessively—just enough to allow for smooth circulation will suffice, helping to reduce the amount of antifreeze needed. *Additional safety reminder:* Ethylene glycol-based coolants come with specific handling instructions. Always refer to the product’s official manual or consult directly with the manufacturer for detailed guidance. *Extra precaution:* When temperatures plummet below -5°C and the spray pump is turned off, make sure to completely drain any remaining spray water and empty the pump itself to prevent ice formation. 4. **Consider additional warming solutions:** - Install insulating covers around the exterior of the equipment. - Inside the unit, equip it with three to four electric heating elements, each rated at 100W or higher, to maintain a stable internal temperature above 5°C. *Important reminder:* Before starting the equipment, thoroughly inspect both the internal components and the cooling water reservoir to ensure there’s no sign of ice buildup. Only proceed with operation once you’ve confirmed that the cooling system is functioning properly and unobstructed. Failure to do so could lead to severe damage to critical components! **A Friendly Reminder:** Even if your water-cooled unit is installed in a cool, well-ventilated area and operates continuously, its coil may still be at risk of freezing. To address this, always add an appropriate amount of ethylene glycol-based antifreeze. Historically, many equipment failures during winter have occurred because users underestimated the risks or failed to implement adequate preventive measures. With colder weather on the horizon—potentially dropping as low as -20°C—now is the perfect time to replace outdated antifreeze fluids with more reliable options. Finally, please note that the majority of past incidents involving frozen water-cooled systems were caused by inadequate management practices and a lack of vigilance on the part of facility operators. Upon receiving this notice, we kindly ask your company’s leadership to promptly assess local weather conditions and adopt suitable frost-proofing strategies tailored to your unique operational needs. **What is Induction Heating?** In induction heating, the workpiece is placed inside an induction coil, typically made of hollow copper tubing designed to carry medium- or high-frequency alternating current (ranging from 300 Hz to 300,000 Hz or even higher). This setup generates a varying magnetic field, which induces eddy currents of the same frequency within the workpiece. These induced currents distribute unevenly across the material—stronger near the surface and significantly weaker toward the core, nearly zero at the center. Leveraging this "skin effect," the process rapidly heats the workpiece’s surface, raising its temperature to 800–1000°C within seconds, while the core remains relatively unaffected.
