Product Overview
The TOJJE DJDD-350P is a 350 PPD ceiling mounted grow room dehumidifier designed for indoor cultivation, controlled growing environments and smart vertical farms. With a nominal dehumidification capacity of 350 pints/day (350 PPD) at 27°C and 60% RH, the DJDD-350P removes excess moisture from the air to help maintain a stable humidity environment for plant growth. Its ceiling-mounted configuration helps save valuable floor space in grow rooms, while the 2000 m³/h circulating airflow supports effective air movement throughout the growing area. The unit provides a 40%–95% RH humidity control range and ±3%RH humidity control accuracy. For automated cultivation environments, the DJDD-350P provides a 24V dry contact interface compatible with TrolMaster controllers, allowing the dehumidifier to be integrated into a broader environmental control system.
Why Choose the DJDD-350P
350 PPD High-Capacity Dehumidification
The DJDD-350P provides a nominal dehumidification capacity of 350 PPD at 27°C and 60% RH, making it suitable for larger grow rooms and other humidity-controlled cultivation environments.
2000 m³/h Airflow
With a circulating airflow of 2000 m³/h, the unit continuously moves and processes room air to support effective moisture removal throughout the growing environment.
Precise Humidity Control
The DJDD-350P supports a 40%–95% RH humidity control range with ±3%RH control accuracy, helping maintain consistent environmental conditions for humidity-sensitive cultivation applications.
TrolMaster-Compatible Control
The unit features a 24V dry contact interface compatible with TrolMaster controllers.This allows the DJDD-350P to be incorporated into automated grow room environmental control systems. Specific wiring and control configurations should be confirmed according to the controller model and project requirements.
Ceiling-Mounted Design
The ceiling-mounted configuration keeps the floor area available for plants, racks, cultivation equipment and other infrastructure.For indoor cultivation projects where floor space is limited, installing the dehumidifier overhead can help optimize the available growing area.
Continuous Drainage
The DJDD-350P uses a hose connection for continuous condensate drainage, supporting extended operation without requiring frequent manual water removal.
Key features include:
-
High efficiency / energy saving / less power consumption without failure
-
Automatic restart on and off with memory function
-
Continuously drainage in 24 hours by tube
-
High precision humidity control with ±3%RH, ambient humidity controlled ＞RH45% based on temp
-
Compressor with 3 minutes delay - starting protection
-
Auot-defrosting function
-
High and Low pressure protection
-
Malfunction display Error code timely
-
Easy operation and simple installation on ceilin
-
24V dry contacts, be compatible with Trolmaster controller

How Does the DJDD-350P Work?
350 Pints/Day Ceiling Mounted Grow Room Dehumidifier Applications
Humidity is an important environmental factor in indoor cultivation. Excess moisture can increase condensation risk and make it more difficult to maintain stable growing conditions.
The DJDD-350P continuously removes moisture from the air and returns dehumidified air to the room, helping maintain the target relative humidity.
The unit is suitable for:
Indoor grow rooms
Controlled cultivation rooms
Greenhouse growing areas
Smart vertical farms
Humidity-sensitive plant production areas
The official TOJJE product specification specifically identifies this ceiling-mounted series for grow facility rooms and smart vertical farms where controlled humidity is required for plant growth.
Installation Considerations
The DJDD-350P is designed for ceiling-mounted installation.The installation location should provide sufficient airflow around the unit and adequate access for inspection and maintenance.The condensate drainage hose should be installed with a suitable drainage route to ensure continuous discharge during operation.For grow room applications, installation should also consider:
Ceiling load capacity
Airflow distribution
Drainage layout
Equipment clearance
Maintenance access
Interaction with other environmental control equipment
For project-specific installation requirements, contact TOJJE before installation.
