Isothermal Dehumidifier DeAir.CRE-600

DeAir.CRE: The Optimal Isothermal Dehumidification Solution for Specialised Environments

In specialised manufacturing and storage environments such as cold stores, pharmaceutical compounding facilities, and laboratories, precise humidity control without altering room temperature is often a challenge. Understanding this, DeAir has developed a range of isothermal dehumidifiers. These floor-standing units not only effectively control humidity but also maintain stable temperatures, conserve energy, and protect product quality.

1. Operating principle

DeAir.CRE operates on the principle of isothermal dehumidification, combining refrigeration technology with a hot gas bypass reheat system. First, moist air is drawn into the unit and passed over the cooling coil, where moisture condenses into water. Then, the dry air is passed over the hot gas bypass coil for reheating before being discharged back into the room. This process allows DeAir.CRE to effectively control humidity while maintaining a stable room temperature, avoiding the coldness associated with conventional refrigerant dehumidifiers.

Furthermore, DeAir.CRE is equipped with a heat rejection module, allowing users to choose between heating or cooling modes according to their needs. When heating is required, the heat rejection coil is deactivated, and heat from the refrigerant is transferred into the room. Conversely, when cooling is needed, the heat rejection coil is activated to expel heat to the external environment, helping to maintain a stable room temperature.

2. Structure

The DeAir.CRE isothermal dehumidifier consists of two main sections:

• Dehumidification section: Compressor, condenser coil, expansion valve, evaporator coil, filter, and fan.
• Heat exchange section: Condenser coil, exhaust fan, liquid receiver, filter drier, high and low-pressure gauges.

3. Installation guide

• Piping connection diagram
• Electrical connection diagram: Maintain a stable voltage with fluctuations within ± 5%.
• Condensate drain pipe installation diagram: The drain pipe should be installed with a slope of >2% to ensure smooth drainage and prevent blockages that could lead to water splashing into the fan compartment.

4. Applications

With its ability to precisely control both humidity and temperature, the DeAir.CRE isothermal dehumidifier is widely used in:

• Cold stores and freezer rooms
• Pharmaceutical and vaccine storage
• Laboratories and cleanrooms
• Food production and storage
• Other applications requiring precise humidity control and stable temperature maintenance.
