Controlling humidity in factories and warehouses is crucial for protecting equipment, raw materials, and goods from mold, corrosion, and damage. Below are four key criteria to help select the right industrial dehumidifier, ensuring optimal performance and cost efficiency.
What size dehumidifier do you need?
The dehumidification capacity refers to the amount of water the device can remove per day, typically measured in liters (L/day) or pints (PPD). Choosing the dehumidifier capacity depends on the space size, required humidity levels, and ventilation system. For warehouses or factories under 500m², dehumidifiers with a capacity of 50-150 L/day may be suitable. Larger spaces (500m² – 5000m²+) generally require machines with a capacity of 200-1000 L/day to ensure effective moisture control.
Selecting the right capacity is essential. If the dehumidifier is too small, humidity will not be adequately controlled, affecting product quality and equipment. Conversely, using an excessively powerful unit for a space with lower humidity needs can lead to unnecessary energy consumption.
Industrial dehumidifiers are essential for specialized manufacturing facilities such as electronics component factories and pharmaceutical factories, etc.
Humidity control requirements
There are two common types of industrial dehumidifiers: refrigerant dehumidifiers and desiccant dehumidifiers. Depending on environmental temperature and humidity control requirements, investors can choose the appropriate type.
What is a refrigerant dehumidifier? When should it be used?
A refrigerant dehumidifier operates by cooling the air to condense moisture into water, similar to household dehumidifiers. This type is commonly used in warehouses and general production facilities where strict humidity control is not required.

What are the advantages of a desiccant (rotor) dehumidifier? When should it be used?
A desiccant dehumidifier (also known as a rotor dehumidifier) is designed for low-temperature environments (<10°C) or facilities requiring precise humidity and cleanliness control. This type uses moisture-absorbing materials to remove water vapor from the air, allowing it to function efficiently in low temperatures while maintaining accurate humidity levels. Desiccant dehumidifiers are commonly used in specialized environments such as cleanrooms, electronics manufacturing, pharmaceuticals, and food storage warehouses, where strict humidity regulation is essential.

Industrial dehumidifier installation
Proper installation plays a key role in optimizing the performance and longevity of an industrial dehumidifier. Below are important factors to consider when installing these systems.
Should you choose a fixed or mobile dehumidifier?
Correct installation helps maximize efficiency and extend the lifespan of the equipment. Investors can choose between two options:
- Fixed dehumidifiers: Suitable for large factories that operate continuously and have a dedicated system for expelling moisture.
- Mobile dehumidifiers: Flexible and easy to move between different areas, making them ideal for small-scale production facilities or those that frequently change layouts.
Drainage system
The drainage system is another important factor to account for during installation. Some dehumidifiers use gravity drainage through piping, while others are equipped with built-in pumps to expel water. In small-scale facilities, manual drainage may also be an option.
Can dehumidifiers be connected with HVAC systems?
For businesses requiring large-scale, synchronized humidity control, dehumidifiers can be integrated into HVAC systems. This solution helps maintain stable humidity levels, enhances efficiency, and reduces energy consumption.
Energy efficiency & control features
Industrial dehumidifiers consume a significant amount of electricity, so energy-saving features should be considered when selecting a unit. Models equipped with variable-speed fans and smart sensors can optimize efficiency by automatically adjusting operation based on real-time conditions, preventing unnecessary energy waste.
Additionally, modern dehumidifiers can be integrated with automatic humidity controllers (humidistats) to maintain precise moisture levels in production environments. Investors may also collaborate with smart factory contractors and MEP (mechanical, electrical, and plumbing) specialists to connect dehumidifiers to BMS (Building Management Systems) or smart factory systems. This integration allows for real-time monitoring and simultaneous control of dehumidifiers and HVAC systems, ensuring accurate management of temperature, humidity, and air cleanliness in critical production areas.
