AD 800-1100

Product catalog summary

Technical Specifications:
The AIRDRY Adsorption Dehumidifiers, models AD 800 and 1100T, have dehumidification capacities of 4.8 Kg/h and 5.0 Kg/h respectively. The process air flow is 800 m3/h for AD 800 and 1100 m3/h for 1100T, with static pressures of 200 Pa and 300 Pa. Both models have a fan nominal power of 0.25 KW and 0.37 KW. The reactivation air flow is 250 m3/h with a static pressure of 180 Pa and a fan nominal power of 0.085 KW. The drive motor nominal power is 11 VA for both models. The regeneration type is electric with an installed power of 6.6 KW. Electrical characteristics include a power supply of 400/3/50 ±5% and maximum power absorbed of 7.0 KW and 7.1 KW. Noise levels are 65 dB(A) and 66 dB(A) for sound pressure, and 93 dB(A) and 94 dB(A) for sound power.

Principle of Operation:
The dehumidifiers operate using two airflows: process air and regeneration air. The process air is dehumidified by passing through a rotor with silica gel, which absorbs moisture. The regeneration air is heated to increase its moisture-holding capacity, allowing it to remove moisture from the rotor. This process is effective between -30°C and +40°C.

Structure and Components:
The dehumidifier is constructed from painted galvanized steel or optional stainless steel. It features high-efficiency fans, a rotor made of desiccant material, and a belt drive system for rotor movement. The regeneration air heating coil uses self-regulating PTC elements for efficiency. The unit includes G4 filters for both air inlets, with higher grade filters available on request.

Control and Electrical Panel:
The dehumidifiers are equipped with a PLC control system for managing regeneration temperature, thermal protection, and other functions. The electrical panel complies with European regulations and includes components like mains switch and relays for protection and control.

Versions and Options:
Various versions are available, including standard, stainless steel frames, and construction site versions with wheels. Optional features include pre/post-cooling coils, proportional control valves, and fan inverters. Standard features include G4 filters, PLC control, and circular spigot connections.

Dimensions and Connections:
Both models have dimensions of 1000 mm x 600 mm x 1000 mm, with empty weights of 145 Kg and 150 Kg. Connection sizes for process air inlet, dry air outlet, reactivation air inlet, and wet air outlet are specified.

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...
