The on-site equipment management personnel accompanied the entire process, first understanding the customer's basic dehumidification requirements. The customer first proposed dehumidification requirements for key areas, that is, local dehumidification for environmental areas. I have conducted specific area and height measurements for the key dehumidification areas. The dehumidification area is connected to the entire space without any obstructions, so when calculating the dehumidification amount for this dehumidification area, a higher safety factor should be considered.
