Re-engineered to boost energy efficiency

The latest Hi-DRI compressed air membrane dryers from Hiline Industries have been reengineered to achieve new standards for performance and energy efficiency. An arrangement of structurally packed, permeable hollow fibres spirally wound on a support core creates a design that combines efficient air flow with high contact areas to boost drying performance.

Products are suitable for in-line installation to ensure the delivery of dry compressed air at point of use.

This is said to ensure maximum effectiveness with virtually any dewpoint or degree of drying being achievable. As the humid compressed air passes through the Hi-DRI unit, water vapour diffuses through the walls of the hollow membrane fibres without loss of compressed air. At the dryer outlet, a small volume of the dry air is expanded and released into the annular space between the membrane fibres and the outer aluminium shell. The air purge sweeps away entrained water vapour to atmosphere as a humid air stream.
