FAQs
1. What types of applications is this round coil best suited for?
The AES HI 3.5 Round Coil 20-53mm is ideally suited for heating pipes, tubes, bearings, and cylindrical metal components. It excels at applications requiring controlled heat for loosening seized parts, breaking rusted connections, and pre/post-weld heat treatments on round surfaces within the 20-53mm diameter range.
2. Is this coil compatible with other induction heater models?
This round coil is specifically designed for use with the AES HI 3.5kW liquid-cooled induction heater system. It connects via the reducer attachment and is not guaranteed to be compatible with other brands or models of induction heaters without proper adapters and matching specifications.
3. How is the coil cooled during operation?
The coil utilizes the same water-cooling system as the main AES HI 3.5kW induction heater unit. The cooling liquid circulates through the coil during operation, maintaining optimal temperatures and preventing overheating. The main unit has a 2.5L cooling capacity which supplies the coil through the integrated 2-meter hose.
4. What maintenance is required for the round coil?
Regular inspection for physical damage, proper cleaning after use, and ensuring connections remain secure are essential maintenance practices. Check for any debris or metal particles that may have attached to the coil during use. The water cooling system should be maintained according to the main unit’s specifications to ensure proper cooling of both the unit and coil attachments.
