What is the Industrial Dehumidification Calculator?

The industrial dehumidification calculator analyzes total moisture load in manufacturing facilities and storage areas. It separately calculates infiltration, personnel, material, and process-originated moisture loads.

Infiltration moisture load calculation is based on door opening frequency, duration, and the humidity difference between outdoor and indoor environments. Personnel moisture load is determined by headcount and activity level (40–300 g/h/person). Process moisture loads are user-defined.

The calculation result provides total moisture load in kg/h and recommends appropriate dehumidification technology. Condensing (mechanical) units are recommended for low moisture loads, while desiccant (silica gel rotor) units are recommended for high loads and low dew point applications.

The tool also analyzes psychrometric conditions, showing the absolute humidity difference between current and target conditions. A safety factor is applied to determine design capacity.

Frequently Asked Questions

What does the industrial dehumidification calculator compute?
It calculates total moisture load in manufacturing or storage facilities: infiltration (door openings), personnel, material, and process moisture sources are analyzed separately.
What is the difference between condensing and desiccant dehumidification?
Condensing units cool air to condense moisture (effective above +10°C). Desiccant units adsorb moisture with silica gel rotor and can reach −60°C dew point.
Why is a safety factor applied?
A 10-20% safety factor is added for unaccountable losses, seasonal variations, and extraordinary conditions. This ensures the equipment has sufficient capacity under all conditions.
Which sectors require low dew points?
Lithium battery manufacturing (−40°C), pharmaceutical production (−20°C), weapon/ammunition storage, and certain chemical processes require low dew points.
How are device recommendations made?
Based on the calculated moisture load, device alternatives in the appropriate capacity range are suggested. Condensing (mechanical) systems for low loads, desiccant (silica-gel rotor) systems for high loads and applications requiring low dew points.
