Drying water-cooled insulated wire/cable and extruded products

23 March 2011

The removal of the residual moisture film from water-cooled insulated wire/cable and extruded products is often difficult to achieve effectively and consistently. Now, ACI’s new ‘LINE-Dry’ System solves this problem whilst also saving energy and reducing running costs when compared with compressed air nozzle arrangements and other existing blower-driven devices.

Compared with compressed air based system, the LINE-Dry achieves up to ten-fold energy savings. Free on-site trials to potential customers in the UK can be arranged to quantify these potential savings.

ACI’s blower powered LINE-Dry system can handle products up to 25mm in diameter at speeds of 500m/min. The blower is an ACI variable speed ‘Multi-Stage’ unit, which has the flexibility to accommodate a variety of products and line speeds.

Two versions are available, one with the dryer heads enclosed to contain displaced moisture the other is an open unit.

The enclosed unit has a pair of facing air delivery plenums.  These can be adjusted to suit different product diameters and are also sprung to allow flexing to accommodate any product distortions/kinks.  A series of baffles serves to isolate wet and dry areas and guard against moisture being re-deposited on the dried product.

The second option comprises two pairs of facing drying heads. These, too, are sprung to allow for product imperfections.

With both versions, the blower and speed controller are mounted on legs and enclosed in an ABS plastic enclosure to prevent moisture ingress.

Air is delivered at up to 2.8psi (80in. SWG) at speeds of 8,800m/min (28,900ft/min) at 80oC.
