Ventless Condenser Dryer - How It Works

Ventless condenser dryers use a dual loop airflow system. The first loop draws in a small amount of ambient air which passes through the condenser for initial heating. The heated air is then pushed into the drum, where it heats up the wet laundry and causes water to evaporate. This air is then looped back into the condenser where it's cooled down - that's the second loop. The air that's already inside the condenser is reheated and sent back into the drum to repeat the process until the clothes are dry. The water that is extracted goes to a tank or an external drain. For more information, see our Ventless Condenser Dryer - How it Drains article.

Understanding the Steps in the Drying Process

1. Ambient air inside the dryer is heated by a heating element.
2. Process air (heated) enters the drum to absorb moisture and dry the load.
3. Process air (heated wet) enters the condenser and is cooled, releasing moisture. Moisture collects in the tub and is removed from the dryer through the drain pump.
4. Process air (cool dry) exits the condenser.
5. Process air (cool dry) enters the heater and is reheated.
6. Process air (heated) re-enters the drum to absorb more moisture and dry the load.

Ventless Condenser Dryers Benefits

• Flexible installation location without venting externally, such as a closet, undercounter or stacked in a corner.
• Lower dry temperatures.
• Less make-up air is required.

Note: Dry times can be 2 to 3 times longer than vented dryers. It does not emit any hot air into the room.
