moisture during PCB assembly can increase the number of failures during assembly, and decrease the circuit assemblies and its life. Exposure to high moisture during Printed Circuit Board (PCB) assembly and manufacturing, leads to Microscopic corrosion Adhesion failures Surface defects Decreased performance of the circuit board. Increase electrical resistance Decrease capacitance. Hygro Desiccant Dehumidifiers provide the ideal low humidity environment in the manufacturing, assembly and storage of these precision, high quality electronic Printed Circuit Boards since they are capable of maintaining RH as low as 1% or even lower at a constant level, regardless of ambient conditions.

DESICCANT ROTOR The desiccant rotor is a high capacity desiccant media captivated in a circumference rim with radial spokes. The spokes attach to a central hub with integral sealed ball bearings. The sealed bearings ride on a solid center shaft. The rotor is held in place with a lock ring on each side the desiccant material, usually a silica gel impregnated into a support. This looks like a honeycomb, which is open on both ends. Air passes through the honeycomb passages, giving up moisture to the desiccant contained in the walls of the honeycomb cells. The desiccant structure is formed into the shape of a wheel. The wheel constantly rotates through two separate air streams. The first stream, called the process air. Is dries by the desiccant. The second air stream, called reactivation or regeneration air, is heated. It dries the desiccant. Technical Specifications Rotor material Desiccant: Solid silica gel Silica Gel Si02 - 82% Glass-fibre- 16% Acrylic surface coating - 2% Technical Data Density: 240kg/m3 Surface compression strength: >200kpa Water vapour absorption capacity :> 40% Max temp: 160Deg C PATENTED Desiccant Rotor Product NOT classified as harmful to the environment Properties No limitation of process air relative humidity. As long as no droplets are introduced in rotor during operation Dehumidification performance after continuous operation for: 5 years: approx. 90% 10 years: approx. 90% 15 years: approx. 90% Incombustible Washable in water or non alkaline detergent after saturation in humid air HYGRO DEHUMIDIFIER ADVANTAGES The Dehumidifier Manufactured by Hygro Tech is non cyclic, rotary type and removes the moisture by process of continues physical adsorption. The desiccant used by Hygro Tech is non toxic, non flammable with maximum moisture removal Capacity Hygro Dehumidifier can maintain Relative humidity (RH) as low as 1% regardless of ambient conditions.
