Aquafog Digital Humidistat Control DH-36

The Aquafog Digital Humidistat Control DH-36 is a professional digital humidity controller that automatically operates compatible Aquafog fogging systems and helps maintain consistent relative humidity in greenhouses, horticultural facilities, agricultural environments, storage areas, and industrial applications.

With a fast-response digital humidity sensor, a broad 5–99% RH control range, real-time humidity display, programmable differential, and built-in alarm functions, the DH-36 provides precise, flexible environmental control without constant manual monitoring.

Its convenient pre-wired, plug-in design simplifies installation, while the easy-to-read digital interface lets operators monitor current humidity and adjust the desired setpoint for their application.

Digital Humidity Control from 5–99% RH

The DH-36 provides a wide adjustable humidity range from approximately:

• 5% RH
• to
• 99% RH

This broad operating range makes the controller suitable for many professional humidification applications, from moderate-humidity environments to applications requiring elevated relative humidity.

The digital display continuously shows the current RH level, giving operators a convenient real-time view of environmental conditions.

Fast-Response Digital Humidity Sensor

The Aquafog DH-36 uses a fast-acting digital humidity sensor that responds quickly to changes in relative humidity.

When humidity falls below the programmed threshold, the controller activates the connected Aquafog fogging system.

Once humidity reaches the selected control point, the DH-36 automatically turns off the fogger.

This automatic operation helps:

• Maintain more consistent humidity
• Reduce unnecessary fogging
• Improve environmental stability
• Reduce manual monitoring
• Improve control in propagation and production areas
• Automate daily humidity management

Programmable Differential

Unlike a basic mechanical humidistat with a fixed differential, the DH-36 provides a programmable humidity differential.

This lets the operator set how far humidity must move from the selected setpoint before the fogging system cycles on or off.

Adjustable differential control can help balance:

• Humidity stability
• Equipment cycling frequency
• Fogging duration
• Environmental response
• Energy consumption
• Equipment operating time

This flexibility makes the DH-36 particularly useful in professional environments where precise humidity control matters.

Real-Time Humidity Display

The digital display continuously shows the current relative humidity level, allowing operators to quickly check environmental conditions directly from the controller.

This is especially useful for:

• Greenhouse operators
• Horticultural growers
• Propagation facilities
• Facility managers
• Agricultural operations
• Industrial humidification systems
• Storage facilities

The digital interface also makes setting and adjusting humidity levels easier than with traditional mechanical controls.

Built-In Alarm Functions

The DH-36 includes built-in alarm functions that help identify abnormal operating conditions.

These include:

• Over-humidity alarm
• Sensor-fault alarm

The over-humidity alarm helps alert operators when humidity exceeds the expected operating level, while the sensor-fault alarm can indicate a problem with the humidity sensor.

These features add an extra layer of monitoring for automated humidity-control systems.

Pre-Wired for Quick Installation

The Aquafog DH-36 is supplied as a pre-wired environmental controller with convenient plug-in connections.

For standard compatible installations, you don't need complicated hard wiring.

This makes the DH-36 particularly convenient for:

• Greenhouses
• Propagation facilities
• Indoor horticulture
• Agricultural buildings
• Mushroom-growing facilities
• Produce storage
• Wood and lumber operations
• Paper manufacturing and storage
• Textile facilities
• Commercial humidity-control systems
• Industrial humidification applications

Electrical Capacity

The DH-36 is designed to work with compatible Aquafog GT 500 and SS-700 fogging systems.

Published electrical specifications include:

• Controller electrical range: 100–240 V
• Frequency: 50/60 Hz
• Controlled-load rating: 1,200 W
• Maximum published load: 10 A at 115 V

When using the controller in installations other than the standard 115 V configuration, always verify that the connected equipment, receptacles, wiring, and electrical load match the supply voltage.

Used With / Compatible With

The Aquafog Digital Humidistat Control DH-36 is primarily designed for compatible GT 500 and Hydro SS 700 hanging-sump, bench-top, and self-contained fogging systems.

Compatible Aquafog products include:

• Aquafog Hydro SS 700-BT Fan – Bench Top
• Aquafog Hydro SS 700-HS Fan – Hanging Sump
• Aquafog GT 500-HS Fan – Hanging Sump
• Compatible with Aquafog GT 500 self-contained systems
• Compatible with Aquafog Hydro SS 700 self-contained systems
• Other compatible Aquafog humidification equipment within the DH-36 electrical load rating

The DH-36 is rated to control compatible GT 500 and SS-700 systems up to 1,200 W / 10 A at 115 V.

Important: Direct-Feed Systems Require DH-36-DF

The standard DH-36 does not include a water solenoid.

For direct-feed Aquafog systems such as:

• Aquafog Hydro SS 700-DF Fan
• Aquafog GT-500 Direct Feed Fan

use the Aquafog Digital Humidistat Control DH-36-DF instead.

The DH-36-DF includes the required water solenoid so the incoming water supply and fogging unit can be controlled together.

When the fogging system switches off, the solenoid also shuts off the incoming water supply, preventing water from continuing to flow into the atomizer while the fan is stopped.

High-Humidity Operation

Although the DH-36 offers a control range up to 99% RH, prolonged operation above about 90% RH is not recommended.

Applications requiring continuously saturated or near-saturated conditions may be better suited to an appropriately configured cycle-timer control strategy.

Ideal Applications

The Aquafog Digital Humidistat Control DH-36 is ideal for:

• Greenhouse humidity control
• Horticultural facilities
• Propagation areas
• Controlled-environment agriculture
• Mushroom production
• Agricultural buildings
