Product use instructions

★Do not in outdoor environments with high humidity.

★When the dry burning electric heating tube heats the air, the components should be arranged evenly and crisscrossed to ensure that components have good heat dissipation conditions and that the air passing through can be fully heated.

★The default material for stock items is stainless steel 201, the recommended operating temperature is <250°C. Other temperatures and materials can be customized, with stainless steel 304 selected for temperatures below 00°C and stainless steel 310S selected for temperatures below 800°C.
