Key issues

Question 1: What are the power and frequency coverage ranges of the SINUS series? What are the main impacts of different frequencies?

Answer: Power coverage ranges from 5kW to 25kW, and frequency coverage ranges from 50kHz to 2000kHz. Frequency determines heating depth: the higher the frequency, the stronger the skin effect, and the more concentrated the heating is on the surface; The lower the frequency, the deeper the heating depth.

Question 2: What are the mandatory requirements for cooling water in this series of equipment? Why not use deionized water?

Answer: The required flow rate is 4-12L/min, inlet pressure is * *<6bar * *, pressure difference is * *>3.5bar * *, and water temperature is 18-25 ℃. The product design allows the use of ordinary industrial cooling water without the need for deionized water, reducing on-site usage and maintenance costs.

Question 3: What are the core differences between SINUS 251 and 252, which are both 25kW models? What scenarios are suitable for each?

Answer: The difference lies in the working frequency:

SINUS 251：500~1000kHz， Suitable for medium depth and medium speed heating.

SINUS 252：1000~2000kHz， High frequency version, suitable for surface ultra high speed heating (such as fine brazing, surface quenching).
