Dryer protects CMM machines
January 1st 2004

Available from Parker Balston is a new Membrane Air Dryer. It is designed to protect coordinate measurement machines (CMMs) from oil and water by providing a reliable source of pure, dry compressed air.

The new dryer has no moving parts and requires no electrical connections, making it suitable for remote and point-of-use installations or for flammable and explosive applications without operator attention.

The unit will dry compressed air to dewpoints as low as 35F at flow rates of up to 600scfm. Dry air is achieved by returning a small portion of the dry product air to sweep out moisture, that preferentially passes through the membranes.

The degree of drying is controlled by varying the compressed air throughout the system. The moisture laden

sweep gas is vented to atmosphere, eliminating potential liquid-handling and freezing problems.

Compact and lightweight, the

air dryer can be mounted easily

on an existing pipeline.

Coalescing prefiltration is used immediately upstream of the membranes to protect them from pipe scale, other particulate and liquids.
