Dehumidifier MASTER DH44 40 L/24h — portable industrial dehumidifier, model 4140.002

The MASTER DH44 40 L/24h is a portable industrial dehumidifier designed to control moisture in demanding environments. With a rated extraction capacity of 40 liters per 24 hours, this unit is intended for use on construction sites, in basements, warehouses and other spaces where reliable humidity reduction is required. The unit combines continuous water collection capability with the option for hose drainage and a robust housing built for frequent transport and on-site handling.

Advantages

The dehumidifier provides a steady extraction rate of up to 40 L/24h, enabling faster drying of building materials and reducing the risk of condensation-related damage. Its portable design and durable cabinet allow for frequent relocation and use in rough environments. Integrated water collection and the option to connect a drainage hose give flexibility for continuous operation without constant emptying. Controls are straightforward to operate, and the device is engineered for stable performance under typical industrial and construction conditions.

Suitable for

• Drying plaster, paint and screed on construction sites
• Moisture control in basements and cellars
• Humidity reduction in warehouses and storage areas
• Water damage mitigation and drying after leaks or floods

Key specifications

• Rated extraction capacity: 40 liters per 24 hours
• Portable industrial design with reinforced housing for transport
• Continuous water collection with internal tank and external hose drainage option
• Suitable for medium to large enclosed spaces typical of construction and storage
• User controls designed for on-site operation and simple setting adjustments

How to use

Position the MASTER DH44 in the area requiring dehumidification, ideally with free airflow around the unit and away from obstructions. If continuous unattended operation is desired, connect a suitable drainage hose to the outlet and route it to an appropriate drain; otherwise use the built-in water collection tank and empty it at intervals. Set the device according to the required dehumidification level and power it on. Monitor the unit periodically for proper drainage and ensure filters and intake areas remain clear of dust and debris to maintain performance.

Usage recommendations

For effective moisture control, place the dehumidifier centrally within the affected space and allow continuous operation until target humidity levels are reached. During construction drying, combine the DH44 with adequate ventilation and targeted heating when necessary to accelerate drying times. Regularly inspect the drainage connection and clean intake areas to preserve efficiency and prolong service life.
