Using microwave-heated ceramic chips instead of standard gas flame or electric coil, the system heats pans with near-perfect balance and lets you control the heat level with incredible precision.

Fan coil air outlet and the air return are not at the same level (such as when the outlet for side inlet and outlet for the last time), air inlet and the air return distance can be relatively close.

It was reported that the overvoltage level of low resistance grounding mode is lower than that of arc suppressing coil mode, but the operation carried out the other way.
