Stability at low humidity levels

The MDC1000 uses desiccant technology to remove moisture down to a very low level. In this instance the air from the facility was pre-cooled before passing through the desiccant wheel.

This increased the relative humidity of the air to make the desiccant wheel more efficient and able to remove the moisture load from the air. The drying process adds heat to the process air, so this was cooled using a post-cooler to deliver the air back into the space at 21⁰C.

The process air on this occasion was introduced directly into the process machine to ensure low humidity at the point of production, with the remaining air ensuring that the room conditions were kept at a low relative humidity - and to maintain a very small differential between the process and the room to prevent moisture transfer via vapour pressure, which might affect the product.

Also, in 2018 an MDC2000 dehumidifier was supplied, delivered and installed at a pharmaceutical test company in Berkshire. The client’s specification was to achieve below 15% RH in a lab environment at 20⁰C.

DT Group, based in Lithuania is a manufacturer of a range of desiccant dehumidifiers for the industrial and commercial markets. Combined with Humidity Solutions expertise, the products can be used to provide stability at very low humidity levels in high end, critical applications.
