Material
1.The cabinet door adopts a double beveled edge process, which increases the structural strength of the same material by 50%.
2.The installation holes are all made using a multi-layer stamping and stretching process, which reduces the sliding wire situation by more than 80%.
3.The inlet and outlet holes adopt a composite structure of knockdown holes and square holes, which can be flexibly selected during on-site installation.
4.The box adopts a double folding process, which increases the structural strength of the same material by 50%.
5.The control circuit adopts a composite design of debugging mode and fire protection mode, greatly reducing the burning of fan and water pump equipment designed for fire protection during debugging.
