How many dehumidifiers are needed for a Class 1 water loss with a volume of 25,000 cubic feet if each removes 125 pints?

1. 1 dehumidifier

2. 2 dehumidifiers

3. 3 dehumidifiers

4. 4 dehumidifiers

The correct answer is: 2 dehumidifiers

In a Class 1 water loss scenario, the amount of water present is relatively low, and dehumidification needs are less intense than in more severe classes. For a space of 25,000 cubic feet, it’s important to determine the total volume of moisture that needs to be removed. Typically, for dehumidifiers, one unit is adequate for a small area but may not be sufficient for a larger space with a volume like 25,000 cubic feet. When using a dehumidifier that can remove 125 pints of water per day, one would first convert the total water volume needing removal into pints to assess how many units are required to handle the moisture efficiently. To determine how many dehumidifiers are necessary, one must understand the efficacy of the dehumidifier in relation to the specific space volume. Given the space size and a typical expected moisture load, it is reasonable to deduce that two dehumidifiers would provide an effective solution to manage the humidity effectively, allowing for efficient drying within the expected parameters. Thus, the decision aligns with common practice in restoration settings, confirming the choice of needing two dehumidifiers for optimal moisture control in a Class 1 loss environment of that size.
