AD 7000-25000

Product catalog summary

Technical Specifications:
The AIRDRY adsorption dehumidifiers are available in models AD 7000, 9000, 11000, 13000, 19000, and 25000. They offer dehumidification capacities ranging from 52.9 to 162.0 Kg/h. The process air flow varies from 7000 to 25000 m3/h, with a static pressure of 400 Pa across all models. The fan nominal power ranges from 4 to 15 KW for process air and 2.2 to 5.5 KW for reactivation air. The units operate on a 400/3/50 ±5% power supply, with maximum power absorption between 81.4 and 272.7 KW.

Principle of Operation:
The dehumidifiers function using two airflows: process air and regeneration air. The process air is dehumidified as it passes through a rotor containing silica gel, which absorbs moisture. The regeneration air is heated to release moisture from the rotor, allowing continuous operation. The system is effective in temperatures from -30°C to +40°C.

Structure and Components:
The dehumidifier's casing is made from painted galvanized steel or optional stainless steel. Fans are directly coupled to motors and can be controlled by frequency converters. The rotor is made of desiccant material and is designed to withstand saturated air. A belt drive system rotates the rotor, and the regeneration air heating coil can be electric or steam-based.

Control and Electrical Panel:
The units are equipped with a PLC control system with a touch-screen terminal for managing various functions, including temperature regulation and alarm resets. The electrical panel complies with European regulations and includes components like mains switches and relays.

Versions and Options:
The dehumidifiers are available in several versions, including standard, stainless steel frames, and construction site versions with wheels. Optional features include higher-grade filters, pre/post-cooling coils, and various control interfaces.

Dimensions and Connections:
The dimensions and weight vary by model, with the largest model (AD 25000) measuring 3850 mm in length and weighing 2150 Kg. Airflow connections are specified for process and reactivation air inlets and outlets.

Adsorption Dehumidifier PRINCIPLE OF OPERATION The dehumidifier operates with 2 airflows. The main airflow, the PROCESS AIR is what is dehumidified and a second, smaller, airflow is used to regenerate the rotor material. Two high efficiency fan and motor assemblies inside the machine create these separate airflows in opposite directions through the rotor. The PROCESS AIR is taken trough the dehumidification rotor and moisture is taken up by the desiccant material bonded to the rotor structure. Mainly Silica Gel is used, which is a hygroscopic material capable of holding many times its weight...
