• Panels: clear
• Material: borosilicate glass 3.3
• Temperature resistance: from -20°C to +120°C
• Use: normal pressure
• Stand: rubber feet

Product description
Aluminium frame with panels made of heat-resistant borosilicate glass 3.3, rear panel made of aluminium, including four shelves made of stainless steel, hygrometer and mounted drying unit, usable with up to 26 shelves, stackable. Electrical power connection 230 V / 50 Hz is required.

Product advantages

• Reinforced aluminium frame with panels made of borosilicate glass 3.3
• Door with magnetic catch and circular rubber seal
• Non slip rubber feet 
• Easy to read electronic hygrometer
• Variable height shelves made of stainless steel
• Automatic drying (manual regeneration of desiccant is not necessary)
• Constant low interior humidity between 20% and 30%
• Telescopic shelves

Applications
Hot, predried products (max. 120 °C) can be stored directly after having been taken out of an oven. The borosilicate glass panels as well as the materials used for the automatic drying unit offer a good chemical resistance against solvents like acetone and ethanol. Please check the chemical resistance before storing any other aggressive products.

With automatic drying that can maintain a constant humidity of between 20% and 30%, SICCO Automatic Desiccators are suitable for long-term storage. Even frequent opening of the door is compensated automatically. They are the ideal solution for storing reference samples, electronics, photo equipment, papers, valuable cultural assets and much more.

Technical data

SICCO Electronic Dehumidification System

How it works:

The essential components of the drying unit are dustless, colour-changing silica gel desiccant beads and two fans.

The automatic dehumidification and desiccant regeneration cycle operates continuously every 20 minutes as follows:

The circulating fan draws for 14 minutes interior chamber air across the desiccant and thus dehumidifies the chamber. During this phase, the oneway flap valves are open to the interior of the desiccator and closed to the exterior.

Afterwards the cirulating fan is stopped and the silica gel is heated electronically to initiate its regeneration. After one minute, the regeneration fan starts to operate and draws air in an opposite direction to the first fan. Due to the air flow, the one-way flap valves to the interior of the chamber are closed and the valves to the exterior environment are open. The desiccant is heated for another four minutes to release the captured moisture to the ambient air.

At the end of the cycle, the circulating fan operates for one minute with ambient air to cool down the desiccant to the ambient temperature.
Then the cycle starts again.

Drying Performance

Test procedure:

After a pre drying period of 10 minutes, a humidity of 100 % is simulated in an Automatic-Desiccator. The desiccator is switched on, the door remains closed tightly until the end of the test. The curves show relative humidity versus time.

Results:

After only 10 hours, the relative humidity inside the desiccator is down to 10 % due to automatic drying. Frequent controls are not necessary. The storage space is bigger since it is not necessary to use silica gel and process errors are avoided.
