1. Why is Sizing Capacity More Important Than Price?
Choosing an industrial dehumidifier based solely on price or a rough area estimate is the most common mistake, leading to waste and inefficiency. A system with accurately calculated capacity based on detailed technical parameters is the key to a successful investment, helping businesses save on operating costs and optimally protect their assets.

2 Major Risks of Choosing the Wrong Capacity
🚫 UNDER-POWERED
- Machine runs 24/7 without rest.
- Never reaches the desired humidity level.
- Electricity bills skyrocket.
- Machine overload reduces its lifespan.
⚠️ OVER-POWERED
- Wasted initial investment cost.
- Space becomes excessively dry.
- Machine short-cycles (constantly turns on/off).
- Damages the compressor, reduces lifespan.
To avoid these risks, the following checklist will be your tool to work with DeAir's engineers to find the most optimal and cost-effective solution for your facility.
2. The Golden Checklist: 4 Steps to Provide Information for DeAir's Most Accurate Consultation
Step 1: Determine the Target Humidity (RH%)
Information needed: Desired humidity level (%).
Why is it important? Each industry and product has a different "safe humidity threshold." Providing this number helps us define the core objective of the system.
Recommended Humidity Levels for Various Industries
(For reference)
- Pharmaceuticals: 15% - 35%
- Food (Confectionery): 25% - 30%
- Electronics: 20% - 40%
- Cold Storage: 5% - 15%
- Garment, Wood: 40% - 55%
Step 2: Analyze the Physical Space
Information needed: Dimensions (Length x Width x Height), Construction materials (walls, floor, ceiling), Number of doors/windows and opening frequency.
Why is it important? These factors determine the "infiltration moisture load" - the amount of natural moisture entering from the outside. A factory with metal sheet walls will have a completely different moisture load than a sealed concrete room. The frequency of door openings also greatly affects the amount of incoming moisture.
Step 3: Evaluate Internal Moisture Sources
Information needed: Number of workers, presence of a fresh air supply system, any processes that generate water vapor (washing, drying...), and especially information about the product (weight, initial and final moisture content).
Why is it important? People, fresh air, and the product itself are the largest sources of moisture inside a space. Calculating these sources will largely determine the required capacity of the machine.
Step 4: Other Environmental Factors
Information needed: Does the room use air conditioning (and what is the maintained temperature)? Location of the factory/warehouse (coastal, inland)?
Why is it important? The ambient temperature directly affects the performance of the dehumidifier (especially condensing types). The climate at the installation site is also a critical factor in selecting the most suitable technology.
