With the advent of the aerospace and defense industries drive for life cycle cost savings, Drytech is pursuing combination technologies to provide longer life desiccant systems.

These systems use a combination of a membrane filter to initially reduce the dewpoint to -40°C, with the desiccator being used as a polishing filter further reducing the dew-point to the - 65° to -75°C range, where applications apply. This combination increases the life of the desiccant by up to 3-6 times its normal life depending on ambient conditions.

Drytech will design and supply just the combination membrane desiccant filter or incorporate it into a self contained compact, robust and lightweight compressor/pump package to meet the rigors of military and aerospace applications.

Membrane Filter Technology
A membrane filter consists of a bundle of hollow membrane microfibres. The compressed air is passed through these hollow fibres, and the water vapor and/or Carbon Dioxide is removed by the principle of selective permeation through the membrane fibre wall.

A proportion of the resulting clean air, termed the 'sweep flow', is then re-directed back along the length of the exterior of the fibre bundle to carry away the impurities and return it to atmosphere. The remainder of the clean dry air is then piped away for use downstream as depeted.
