DEFINITION
What is an ultrasonic humidifier?
An ultrasonic humidifier adds moisture to air as fine water mist without a heating process. This family provides humidity compensation for greenhouses, textile applications, cold storage and other controlled environments. Selection depends on the required humidification output, water quality, airflow, room conditions and installation position; automatic humidity-control functions vary by model and configuration.
Confirm humidification output, water quality and supply, mist absorption distance, airflow, power supply and controls for the project.
RYJS-21D has a published humidification output of 21 kg/h. Confirm rating conditions and the required output for the project before selection.

102 kg/h SELECTION STEPS
How to select the right configuration
- Step 1 — define the humidification requirement. Provide the operating temperature, current and target relative humidity, room volume and ventilation conditions so the required moisture addition can be reviewed.
- Step 2 — review water supply and mist distribution. Provide water-quality information, available supply conditions, the airflow path and outlet position. Confirm water treatment, supply pressure and mist absorption distance for the project.
- Step 3 — compare humidification output in kg/h. Review the model's published output, power supply and control method. Confirm rating conditions, humidity-sensor location and any external control interface before ordering.
FAQ
Frequently Asked Questions
How much humidification output does the project need?
The published humidification output for RYJS-21D is 21 kg/h. Provide temperature, current and target humidity, room volume and ventilation conditions for an output review. Confirm rating conditions and final selection for the project; floor area alone is not enough.
What water quality and supply are required?
Provide the water source, available water-quality analysis and supply conditions. Water treatment, inlet pressure and maintenance requirements must be confirmed for the model and project before ordering.
What mist absorption distance and control arrangement should be planned?
Provide the outlet layout, airflow path, temperature, target humidity and nearby surfaces for review. Confirm the mist absorption distance for these conditions. The model tables list automatic humidity control; confirm sensor placement and any required external control interface for the selected configuration.
