Master Humidity Control Even in the Cold
Maintaining optimal humidity levels in low-temperature environments has always been a challenge in greenhouse cultivation. Ice buildup can disrupt dehumidifier performance, leading to inefficiencies, downtime, and inconsistent climate conditions.

The electric defrosting system for the DG-12 and DG-3 solves this issue, making reliable and efficient dehumidification possible in temperatures as low as 6°C (43 °F).

Ensure precise humidity control across a wider temperature range, supporting healthier plants and higher yields year-round.

Please note: the defrost coil is available only by pre-order and increases the unit height by approximately 5–10 cm. (2–4 in.).

How the Electric Defrost System Works

The electric defrost coil is designed to prevent ice buildup on the heat exchangers during operation in low-temperature environments. This is achieved through a controlled, cyclic heating process that melts frost, allowing for a smooth dehumidification process.

Key Features

Continuous Operation

The system automatically activates when frost begins to form, ensuring uninterrupted moisture removal.

Wide Temperature Range

Operates effectively in temperatures as low as 6°C (43 °F), making it ideal for cold-climate cultivation or crops requiring cool nighttime conditions.

Energy Efficiency

The targeted use of electric coils minimizes energy consumption while maintaining DryGair’s industry-leading efficiency standards.

By integrating this mechanism into the DG-12 and DG-3, you can achieve consistent humidity control regardless of external temperatures.
Benefits of the Electric Defrost Coil
Reliable Performance in Low Temperatures
The electric defrost system allows the DG-12 and DG-3 to operate efficiently in environments where temperatures dip below 10°C. This makes it an excellent solution for crops that thrive in cooler conditions, such as strawberries, winter vegetables, and certain herbs.
Eliminate Ice Buildup
Ice formation on dehumidifier coils can severely impact performance and lead to downtime for manual defrosting. The electric defrost coil eliminates this issue entirely, ensuring continuous operation and stable humidity levels.
Healthier Plants
Stable humidity control is critical for preventing diseases like powdery mildew, botrytis, and more. By maintaining consistent conditions even at low temperatures, you can protect your crops from these common threats while optimizing transpiration and nutrient uptake.
Energy-Efficient Operation
Unlike traditional heating systems used to prevent ice buildup, DryGair’s electric defrost coil is designed to minimize energy consumption. This ensures growers can maintain sustainable operations without compromising performance or increasing costs.
Low Temperature Dehumidification Applications

The electric defrost coil expands the versatility of the DG-12 and DG-3 units, making it suitable for a broader range of crops and growing conditions:
Cold-Tolerant Crops: Ideal for strawberries, berries, herbs, greens, and other crops that require cool nighttime temperatures.
Year-Round Cultivation: Supports both winter and summer growing seasons by adapting to varying temperature requirements.
Greenhouse & Indoor Farming: Ensures reliable humidity control in controlled environments with fluctuating or low temperatures.
