Introduction of Guard120 Commercial Ceiling Mounted Dehumidifier

The 380V / 50Hz Guard120 dehumidifier is suitable for mainstream three-phase power markets in Europe, Asia, the Middle East, and Africa, and is specifically designed for high-load industrial and commercial environments. The Guard120 can remove 120 liters of water per day at the AHAM condition (26.7 ℃/60% RH), even reach 70 L/D when the temperature is around 15 °C. Its control board is magnetic and can be attached to any part of the machine shell, providing high flexibility during use. The unit comes with a nylon filter and can be optionally purchased with MERV 8 filters. The machine adopts gravity direct drainage and frees users from regular emptying. More details and advantages await you to discover.

Details of Guard120 Grow Room Dehumidifier

The Guard120 features a front air intake and rear air discharge design, ensuring optimized airflow for improved heat exchange efficiency and overall dehumidification performance. The refrigeration system is specially optimized with individually tuned capillary tubes, precisely matching refrigerant flow in each circuit to achieve uniform evaporator cooling, making the unit particularly stable under low-temperature operating conditions. Performance in low ambient temperatures has been further enhanced, allowing operation throughout the entire cannabis cultivation cycle, with a minimum operating temperature of 13 °C.

To improve system safety and durability, high- and low-pressure protection has been added to safeguard the compressor under abnormal conditions. A refrigerant charging valve is integrated to simplify servicing and refrigerant replenishment. The unit is equipped with an external humidity sensor interface for more accurate humidity detection, as well as a Modbus communication interface to enable connection with third-party supervisory control systems.

Additional refinements include clear on-unit labels for error codes, interface instructions, and safety warnings, allowing faster operation and reducing the risk of misuse. The packaging structure has also been upgraded, using a reinforced wooden-strip carton frame that provides enhanced protection during transport while remaining easy to unpack and install.

Features of Guard120 Grow Tent Dehumidifier

Design for Plant Growth

The unit delivers performance comparable to Quest-class dehumidifiers. Its effective operating range of 13.3 °C to 35 °C fully supports humidity control requirements throughout the cannabis growth and flowering stages. Even at 13.3 °C, the unit maintains continuous operation without entering defrost mode, ensuring consistent dehumidification under low-temperature conditions.

Flexible Control Options

An external humidity sensor interface enables more precise environmental monitoring and control. The system supports Modbus communication and APP control, allowing seamless integration with third-party environmental control platforms.

Optimized Refrigeration System

The refrigeration system features dynamic refrigerant pressure monitoring, providing active compressor protection under varying load conditions and extending compressor service life.

Memory Auto Restart Function

It ensures the unit resumes previous operating settings after power restoration, maintaining environmental stability without manual intervention.

Auto-Defrost Function

An automatic defrost system with adjustable defrost timing and temperature setpoints allows flexible adaptation to complex low-temperature conditions, minimizing efficiency loss while ensuring safe operation.

Durable Heat Exchange Components

The system utilizes thickened copper tubing, enhancing pressure resistance, heat transfer efficiency, and long-term operational durability.
