A ducted dehumidifier is a dehumidifier that is connected to a duct or ventilation shaft with either the supply air, return air,or both. The duct work can be connected to an existing HVAC system or ducted out on its own to an exterior area.
Are all dehumidifiers ducted?
Depending on the application, a dehumidifier doesn’t have to be ducted to do its job. Only dehumidifiers with a strong enough fan
to overcome the static pressure of the ductwork are capable of being ducted.
Why use a ducted dehumidifier?
Often the space that needs to be dehumidified is not the same space that houses the dehumidifier, the application requires a better distributed airflow, or there are multiple spaces needing dry airflow. By ducting the dehumidifier to these remote locations, the user has the freedom to install the dehumidifier where ever it is convenient, easily distribute dry air across a wide area, or can use a single dehumidifier to dry multiple spaces. Ducted dehumidifiers also have the added benefit of being able to condition fresh outside air to the space rather than just circulate stale indoor air.
Why might you need a ducted dehumidifier?
1. IF YOU HAVE AN ESPECIALLY LARGE SPACE.
If your space is very large, such as an indoor ice rink or a water treatment facility, using a ducted dehumidification system
maybe the best option. By nature, the system can distribute the air evenly or target trouble areas.
2. IF THE AREA NEEDING TO BE DRIED HAS LIMITED POWER AVAILABILITY OR SPACE CONSTRAINTS.
If, such as in an indoor pool, the area needing to be conditioned doesn’t have available space to house the dehumidifier, ducting the unit from a utility closet gives the flexibility needed to manage the space properly.
3. IF YOUR SPACE HAS POOR VENTILATION OR HAS MULTIPLE COMPARTMENTS.
Spaces that have poor ventilation often benefit from a ducted dehumidifier, as the system’s design allows for fresh air to
circulate through the space. Using a ducted dehumidifier can help such areas by maintaining a healthy air quality. This is also beneficial in facilities like Self-Storage or float spas where there are multiple smaller rooms that need to be addressed.


* Since 2010 R22 is no longer in use by manufacturer’s of new air conditioners and heat pumps
* As of 2020 R22 will no longer be imported or manufactured
* R22 contributes to the depletion of the ozone layer
* R22 is less capable of absorbing and releasing heat than R410a refrigerant, making it less energy efficient
* The price of R22 continues to rise as the remaining supply diminishes
R410a refrigerant:
* R410a comes in all newly-manufactured air conditioners and heat pumps
* Unlike R22, R410a does not contribute to the depletion of the ozone layer
* R410a is better at absorbing and releasing heat than R22, making it more energy efficient to use
* Since R410a operates at higher pressures it requires the use of tougher and more durable air conditioner parts. Better quality
parts reduce the risk of your system overheating and breaking down.
It’s not hard to see why R410a is a substantially better refrigerant.
