Guide to Choosing a Commercial Humidifier
With the wide variety of industrial and commercial humidifiers available, selecting the right system for your business can be time-consuming.
Different industries have specific humidity requirements tailored to their processes, products, and environmental conditions. For example, data centres may require precise humidity control to protect sensitive equipment and prevent static, while printing facilities need consistent levels to ensure product quality and prevent material distortion.
In this guide, we will cover:
- The main types of humidifiers used in commercial and industrial settings
- Common applications for humidification
- Key considerations when specifying and sizing a commercial humidifier
Types of Industrial Humidifiers
Commercial or industrial humidifiers are generally classified into two main categories:
- Isothermal (steam) Humidifiers
- Adiabatic (cold-water) Humidifiers
Isothermal (steam) humidifiers produce steam by heating water using electricity, gas, or existing steam from sites and introduce it into the air to raise humidity levels. This method provides precise and hygienic humidity control, making it ideal for applications such as healthcare, cleanrooms, and manufacturing environments where sterility is essential. Steam humidification systems can be used to add humidity directly in-room or via ductwork.
Adiabatic (cold water) humidifiers use low-energy processes to add moisture to the air without heating the water. These systems are typically more energy-efficient and are well-suited for applications where lower energy consumption is a priority, such as warehouses, data centres, or offices. Cold water humidifiers also provide free adiabatic cooling as part of the humidification process.
There are three main types of adiabatic (cold water) humidifiers:
- High-pressure humidification
- Ultrasonic humidification
- Evaporative humidification
Each type offers distinct advantages, and the best choice depends on factors such as target humidity levels, application needs, water quality, space size, and existing infrastructure.
Industrial Humidifier Applications
Industrial humidifiers are used across a wide range of sectors to control relative humidity (RH) for process efficiency, product quality, comfort, and compliance. Here are some of the most common industrial humidifier applications:
Manufacturing & Production
- In factory environments, increasing relative humidity can help prevent static, improve product quality, and increase machine efficiency
- Spray booths need a relative humidity of at least 70% to reduce the rate of water-based paint evaporation during the curing phase, which allows an even coating on bodywork. Due to the large amount of moist air needed to cover these industrial paint spray booths, high-pressure or resistive humidification systems are often the most economical solutions
Data Centres and Server Rooms
- Humidification in data centres and server rooms is vital for preventing electrostatic discharge (ESD), which can damage sensitive equipment. Alongside humidity, temperature control is crucial to prevent overheating and system failures. Cold water humidification systems efficiently maintain humidity while easing the load on air conditioning, reducing overall energy consumption
Food & Beverage
- In bakeries, maintaining proper humidity is essential to keep dough moist during proofing and fermentation, ensuring consistent texture and quality. Additionally, increasing moisture in the air helps suppress airborne dust particles, common in environments with flour and other dry ingredients, reducing the risk of allergies and improving air quality for staff throughout the production process
- In cold storage rooms, precise humidity control prevents dehydration, weight loss, and quality decline in goods like produce, meat, and dairy. As cold air holds less moisture, humidification systems such as cold water or steam help maintain optimal levels, reducing spoilage and extending the shelf life of products.
Healthcare & Laboratories
- Adding moisture through steam humidification helps to maintain sterile conditions, reduces the spread of bacteria and viruses in hospital environments, and protects sensitive laboratory equipment from electrostatic discharges.
Museums, Archives & Art Galleries
- Precise humidity control in museums, archives, and art galleries is essential to preventing significant damage to materials like paper, canvas, wood, and paint, putting valuable artworks and historical artefacts at risk. Steam humidifiers are commonly used to maintain stable moisture levels and safeguard delicate collections from long-term deterioration.
Cleanrooms & Pharmaceutical Environments
- Strict humidity control is essential in cleanrooms and pharmaceutical settings to protect product integrity, ensure process consistency, and meet regulatory standards. Fluctuations can compromise materials, cause electrostatic discharge, and disrupt testing. Steam humidifiers provide precise, hygienic moisture control to maintain contamination-free, stable environments
Agriculture & Horticulture
- In greenhouses and cannabis farms, accurate humidity control supports healthy growth, disease prevention, and higher yields. Cannabis plants need varying humidity levels at different stages—higher during vegetative growth and lower during flowering to prevent mould. High-pressure misting and ultrasonic humidifiers help maintain optimal conditions for consistent, high-quality crops
- Mushrooms require 85–95% relative humidity for proper growth and yield. Even small drops in moisture can cause drying, cracking, or reduced mycelium development. Ultrasonic and high-pressure misting systems create stable, moisture-rich environments that promote healthy growth and maximise productivity.

Selecting and Sizing an Industrial Humidifier
Environmental requirements and operational factors are essential when determining the correct humidifier for your facility. This ensures that the humidification system delivers reliable and efficient humidity control. Here is a breakdown of key considerations:
- Application requirements
- Room volume and air change from existing air conditioning and ventilation.
- Water quality
- Type of humidifier
- Temperature and humidity levels
- Control system integration with existing BMS and HVAC systems, including additional temperature and humidity monitoring
- Installation and space constraints, i.e. ceiling height, mounting options (ducted vs. direct room injection), access for maintenance, etc.
- Energy efficiency and operating costs
