PRODUCT DESCRIPTION
The APSOL DECKER – DAD series desiccant dehumidifier is specially designed for applications requiring low-humidity control, with the capability to achieve a dew point as low as -40°C.
● Mechanical construction: The frame is made of extruded aluminum profiles with thermal bridge resistance; the casing is constructed of PIR panels, 50 mm thick with a density of 40 kg/m³, providing optimal thermal insulation and completely eliminating external condensation. Optional configurations include anti-corrosion coating or explosion-proof design, depending on application requirements.
● Airtightness: The entire housing is engineered to meet strict airtightness standards, ensuring precise control of temperature and humidity conditions.
● Standard equipment: Desiccant rotor, process fan, regeneration fan, electric heater, air filters, and a complete electrical control system.
OPERATING PRINCIPLE
The unit operates on the principle of two separate air streams:
Process Air Stream:
● This is the primary airflow, with a volume approximately three times greater than the regeneration air stream.
● Air from the controlled space is drawn through a filter to remove dust particles before entering the desiccant rotor.
● Within the rotor, moisture is adsorbed by the desiccant material, producing clean and dry air, which is then supplied back to the conditioned space.
Regeneration Air Stream:
● Ambient air is taken from outdoors and heated up to approximately 140°C.
● The hot air passes through the regeneration sector of the rotor, releasing the absorbed moisture, which is then exhausted to the outside by the regeneration fan.
Desiccant Rotor:
● The rotor rotates continuously at a low speed (8–15 revolutions per hour).
● The rotor surface is divided into two independent sectors: 270° for process air dehumidification and 90° for regeneration.
KEY ADVANTAGES OF APSOL DECKER DESICCANT DEHUMIDIFIER
High Performance: Equipped with NICHIAS desiccant rotor (Japan, manufactured in Vietnam) – a leading technology capable of achieving ultra-low dew points down to -90°C.
Reliable Fan System: Utilizes Kruger fans (Soler & Palau Group – Spain, manufactured in Vietnam), renowned for high durability, convenient maintenance services, and widespread availability across Asia and Europe.
Advanced Control: Integrated electrical system with PLC, HMI, and BMS connectivity via Modbus RTU; supports monitoring, operation, and remote control via smartphone. IoT technology has been applied to all DECKER products since 2020.
Certifications: Production management compliant with ISO 9001:2015 and certified to meet European quality standards (CE).
