Air Wipes

Effective removal of water or other cooling agents from extruded wire is essential to ensure proper processing, testing, inspection, printing and packaging. Our air wipes provide a robust, cost effective, low energy solution to the problems of drying wires and cables.

How Air Wipes Work

Standard air wipes rely on high pressure and large volumes of air to affect drying. Techna's air wipes use a patented design matched to wire diameter that allows compressed air to rapidly expand to atmospheric pressure and in the process, accelerating a thin layer of air around the wire to almost the speed of sound. This release of kinetic energy provides better efficiency than systems that rely on high air volumes to dry product.

The configuration of the alumina ceramic air chamber also acts to keep the wire centralised within the airflow and reduces the entrainment of ambient air within the system, which typically would dilute the energy available to dry the wire.

Techna offer two different types of Air Wipe:

Monoblock Air Wipes

Designed for use primarily with bare wires, the Monoblock Air Wipe model incorporates a replaceable cylindrical alumina ceramic insert pressed into a polymer mounting block and sealed with O-rings.

Monoblock models are available for use with wire up to 10mm (0.4") diameter.

Clamshell Air Wipes

The Clamshell Air Wipe design of our larger models is perfect for insulated wire or cable and opens to allow welds or extrusion bulges to pass through. Replaceable alumina ceramic inserts line the wire path and are surrounded by a tough polymer housing with a robust integral hinge mechanism. All standard fasteners, springs and hinge pins are stainless steel.

Units are supplied with their own air filter regulator including gauge and drain to enable easy set up and monitoring.

Clamshell air wipe models are available for use with materials up to 114mm (4.5") in diameter.
