Aquafog Digital Humidistat Control DH-120-DF
The Aquafog Digital Humidistat Control DH-120-DF is a precise, fast-acting digital humidity controller designed for compatible Aquafog XE direct-feed fogging systems.
With a wide 5–99% RH operating range, real-time humidity display, adjustable setpoint and differential, included water solenoid, and built-in alarms, the DH-120-DF provides dependable automatic humidity management for greenhouse, horticultural, agricultural, and industrial environments.
Fast Digital Humidity Control
The DH-120-DF uses a fast-response digital humidity sensor to continuously monitor relative humidity.
When humidity falls below the programmed level, the controller activates the connected Aquafog XE fogger. Once the system restores the desired humidity level, it automatically switches off.
This helps maintain more consistent environmental conditions while reducing manual adjustments.
Wide 5–99% RH Operating Range
The Aquafog Digital Humidistat Control DH-120-DF operates across a broad 5–99% RH range, making it suitable for many controlled-environment applications.
Typical uses include:
- Greenhouses
- Propagation areas
- Commercial horticulture
- Indoor growing facilities
- Agricultural buildings
- Plant production areas
- Warehouses
- Manufacturing environments
- Industrial humidification
- Environmental control applications
Prolonged operation above 90% RH is not recommended. For continuously high-humidity environments, another control method may be more appropriate.
Real-Time Humidity Display
The digital display provides real-time relative humidity readings, allowing operators to monitor environmental conditions quickly and conveniently.
This provides greater visibility and control than a basic mechanical humidistat.
Adjustable Setpoint and Differential
The DH-120-DF lets you adjust the humidity setpoint and differential range to match your application's needs.
This gives operators greater control over when the connected fogging system activates and shuts off.
Water Solenoid Included
Because direct-feed systems require the water supply to stop whenever the fogger switches off, the DH-120-DF includes a water solenoid.
The solenoid coordinates water flow with fogger operation, helping prevent unnecessary water flow when the system is off.
Built-In Alarm Functions
The controller includes important monitoring features such as:
- Over-humidity alarm
- Sensor fault alarm
These alarms help alert operators to abnormal humidity conditions or problems with the humidity sensor.
Controls One Aquafog XE Unit
The DH-120-DF controls one compatible Aquafog XE direct-feed unit.
Its electrical capacity is rated at:
- 1,800 W
- 15 A at 115 V
- 115 V / 60 Hz
