Why Does My Dehumidifier Quickly Reduce RH from 80 to 52 and Then Not Lower Anymore?

1. Size and Capacity of the dehumidifier:

The dehumidifier may not be appropriately sized for the space you are trying to dehumidify. If the capacity of the dehumidifier is not sufficient for the size of the room or the level of humidity, it may struggle to bring the humidity down further.

 

2. Operating Conditions of the dehumidifier:

Dehumidifiers are typically designed to operate within a certain range of temperature and humidity levels. If the room is too cold or too hot, or if the humidity level is extremely high, the dehumidifier may not be as effective.

 

3. Air Circulation of the working zone:

Proper air circulation is crucial for a dehumidifier with pump for basement to work effectively. Ensure that there is good airflow in the room. If the room is poorly ventilated, the dehumidifier may not be able to extract moisture efficiently.

 

4. Maintenance and Cleanliness of the dehumidifier:

Regular cleaning and maintenance of the commercial dehumidifier are important. Over time, dust and debris can accumulate on the coils and filters, reducing their efficiency. Make sure you clean or replace the filters as recommended by the manufacturer.

 

5. Defrost Cycle of the dehumidifier:

Some dehumidifiers have a defrost cycle that can temporarily stop the dehumidification process in order to prevent frost buildup on the coils. During this cycle, the dehumidifier may not be actively removing moisture from the air.

 

6. Humidity Source removal:

If there's a constant source of moisture in the room (like a leak or high-humidity activities such as cooking or showering), the dehumidifier may struggle to maintain a lower humidity level.

 

7. Dehumidifier Capacity Limit:

Some dehumidifiers are designed to maintain a certain humidity level rather than continually lowering it. Once they reach the desired humidity level, they may cycle on and off to maintain it. However, the LGR dehumidifier developed by Preair can be operated in an environment of 20%-90%RH. Contact Preair for high quality dehumidifiers.
