AIRDRY ADP 9500

The TFT ADP 2000 - 9500 dessicant dehumidifier for food processing and other demanding applications.

PRINCIPLE OF OPERATION.

The dehumidifier uses two opposing airflows: process air (dehumidified) and regeneration air (used to dry the rotor). Two high-efficiency fans drive these flows through a slowly rotating silica gel desiccant rotor, which absorbs moisture from the process air and delivers a dry air stream for supply or further treatment.

The system works reliably from –30°C to +40°C. A motor and gearbox turn the rotor slowly by belt drive. Regeneration air is heated (typically +100°C above ambient) and passed through the rotor in the opposite direction, releasing absorbed moisture as vapor to the outside. This prepares the rotor for continuous operation.

STRUCTURE.

Casing: galvanized steel insulated panels (painted or stainless steel AISI304 optional).

Easy access via removable top and front panels.

Standard duct connections for airflows.

FANS.

Direct-coupled motors (IP55, ISO F, class B), single- or three-phase.

Protected by safety panels during operation.

Standard fixed speed; optional frequency converter for variable airflow control.

ROTOR.

Honeycomb, heat-resistant structure containing silica gel.

High absorption capacity in compact design.

Withstands saturated air, fan stoppages, and pre-cooling coils.

Non-combustible and non-flammable.

TRANSMISSION SYSTEM.

Belt-driven rotor, 6–12 rph, powered by motor and gearbox.

Belt tensioning prevents slip; rotor visible for inspection.

Mounted on ball bearings around central shaft.

REGENERATION HEATING COIL.

Electric: Steel elements in multiple control banks; optional proportional power modulation for efficiency.

Steam: Stainless steel tubes with aluminum fins; includes modulating valve for flow control.

FILTERS.

Two G4 filters (process and regeneration air).

Higher grades available on request.

PLC CONTROL.

Touch-screen PLC regulates temperature, protection, cooldown, sequencing, alarms, humidity/dewpoint, and pre/post-treatment.

Can integrate with external humidistats, BMS systems, and MODBUS protocols.

ELECTRICAL PANEL.

Built to EU standards (73/23, 89/336).

Top access panel.

Includes mains switch, thermal switches, relays, and terminal block for remote ON/OFF and alarm contacts.
