System Enables Removal of Residual Moisture Film

The new Line-Dry system from Air Control Industries (ACI) enables the removal of the residual moisture film from water-cooled insulated wire/cable and extruded products. It is also said to save energy and reduce running costs in comparison with compressed-air nozzle arrangements and other existing blower-driven devices. When compared with compressed-air systems, up to 10-fold energy savings can be achieved, according to the company.

Free onsite trials to potential customers in the UK can be arranged to quantify potential savings. ACI's blower-powered Line-Dry system can handle products measuring up to 25mm in diameter at speeds of 500m/min. The blower is an ACI variable-speed Multi-Stage unit controlled via a speed controller, which enables different products and line speeds to be accommodated. Two versions are available - one has the dryer heads enclosed to contain displaced moisture and 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 inverter 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 80C.
