Dantherm AD 935 S Condensation Dehumidifier
Heated, Ductable Drying for Professional Applications
The Dantherm AD 935 S is a versatile professional condensation dehumidifier designed for construction drying, water damage restoration and targeted airflow applications. It builds on the proven AD 9 series platform but adds an integrated 1kW electric heater and two 100mm duct connections, enabling warm, dry air to be directed into voids, crawl spaces, cavities and other difficult-to-reach areas.
Reliable Drying Performance
With an extraction capacity of up to 28 litres per 24 hours at 30°C and 80% RH, the AD 935 S provides dependable drying in small and medium-sized rooms, site areas and structural materials. It operates effectively between 5 and 30°C with a humidity working range of 30–90% RH. A single-stage fan delivers 400m³/h airflow for focused and controlled air movement.
Durable, Mobile and Easy to Service
The robust steel chassis features large wheels, a telescopic handle and a stackable frame, making the unit suitable for rental fleets and contractors operating multiple machines. Service access is simplified through removable covers, supporting quick cleaning, inspection and replacement of components to minimise downtime.
Advanced CC 6 Control with Remote Monitoring
The integrated CC 6 controller provides clear, intuitive operation through a fully graphical display with colour-coded status indication. It is prepared for wireless integration with Dantherm’s Simplify system, allowing technicians and fleet managers to review performance, monitor alarms and adjust settings remotely.
Flexible Drainage and Professional Metering
The AD 935 S includes an 8 litre water tank and a 15mm gravity drain connection, and it automatically detects an optional condensate pump kit when installed. A MID-approved kWh meter and non-resettable hour counter are fitted to support accurate reporting for extended drying projects and hire use.
Efficient Refrigeration with Low-GWP Refrigerant
Using R454C refrigerant with an extremely low Global Warming Potential, the AD 935 S delivers efficient, professional drying performance. Maximum power consumption is 1,785W when the heater is active, making the unit suitable for applications requiring accelerated evaporation or temperature stabilisation.
Typical Applications
Common applications include construction and refurbishment sites, industrial drying, preservation spaces, commercial buildings, storage rooms, warehouses and water damage restoration projects where directed heated airflow is required.
