Everything You Need to Know About Steam Humidifiers

Steam-based humidification systems are capable of compensating for reduced or fluctuating relative humidity (RH) levels at any time of the year, regardless of climate. This way, environments can be protected against adverse health, comfort, and productivity-damaging issues. Steam humidifiers such as Condair’s SE offer the ideal humidity control solution in the form of an energy-efficient, resilient, and powerful product.

The Steam Generation Process

The Steam Generation Process uses a meticulously engineered method known as isothermal humidification. Steam humidifiers such as Condair’s SE utilize central facility steam to boil potable, reverse osmosis, or deionized water. This process produces purified, hygienic atmospheric steam that is free of toxins, which is then introduced into the airstream to maintain consistent relative humidity control.

How a Steam Humidifier Works

A steam humidifier uses data from a humidistat to continuously monitor indoor relative humidity (RH). When humidity drops below the set level, the humidistat signals the system to generate steam by heating water in a reservoir. The resulting steam is then distributed evenly into the air to restore and maintain optimal humidity conditions.

Steam Humidification and Infection Control

Steam humidifiers such as Condair’s SE help support infection control by maintaining balanced relative humidity levels, typically between 40% and 60% RH. At lower humidity levels, airborne aerosols can remain suspended longer and spread more easily. Proper humidification increases droplet mass, causing them to settle more quickly and reducing airborne transmission risks. This is especially important in healthcare environments such as hospitals and care facilities.
