There are many different types of industries and businesses that require a constant humidity within their facilities. The most common application for humidity control is for greenhouses, but it is also necessary for many textiles plants, manufacturing area and in production facilities where there are combustible or flammable materials.
Humidity control is needed for wood processing facilities and storage facilities. Food production areas may also require specific humidity levels for consistent product quality. Regardless of the specific industry, the capacity and ability to maintain the humidity at the necessary level are essential in many applications.
In the past, humidity controllers were designed to allow for a particular humidity level to be pre-selected and set. The setting for humidity was separately from temperature, which potentially creates a problem as humidity and temperature are related. New options in programmable and smart humidity controller models allow for a variety of setting and options for more effective control.
Considerations with Controllers
Different types of humidity controller units will have one of two types of sensors. Most will feature an internal sensor, which means that the controller contains the sensor and it will be a one zone application. This requires the sensor be mounted in the area where the readings will occur.
The other option is to use a humidity controller with the possibility for an external sensor to be wired into the system. The benefit of this configuration is the ability to locate the sensor and the controller unit in different areas. For some industrial applications, this allows the controller to be centrally located allowing for easier access.
Accuracy in Control
The programmable or automatic types of controllers are highly accurate. The top manufacturers will provide guidelines for the use of specific models with many designed for utilization in conditions of up to 99% humidity and 99 degrees with very high levels of accuracy. The accuracy factor is always important in essential humidity control environments and will always be an important reason to upgrade to programmable options.
