VERTICAL DRYERS

Vertical dryers are used when space is at a premium or when process variables dictate a vertical dryer is required to accommodate the entrance or exit of the web. Common in the graphic arts industry, vertical dryers can also be used in many other applications. ASI has designed and manufactured vertical dryers for a wide variety of applications, including flexography printing on foils and films and numerous graphic arts applications.

ASI's AirBars

​

AirBar design is one of the most important aspects to dryer performance and choosing the correct AirBar is a critical step in every dryer design. ASI has designed and developed over two dozen AirBars that are tailored to specific drying environments, products, and criteria. AirBar selection is based on multiple process variables, including line tension, web porosity, web weight, temperature sensitivity, coating characteristics, and solvent volatility.

​

Our AirBars include:

​

• slot nozzles - impingement-style AirBars for high heat and mass transfer applications;

• hole bars - impingement-style AirBars that supply dilution air for slower drying applications;

• airfoils - flotation AirBars that can be mounted above or below the web to provide unparalleled lift or hold-down force and can be used:

  • with low web tensions without web flutter; and

  • for single sided web flotation;

• dual purpose AirBars - ASI's impingement-style slot nozzles combined with a moveable wing to convert to a dilution-style AirBar; and

• BW-style AirBars - flotation AirBars that can float the heaviest of webs and can be mounted above or below the web to provide high heat and mass transfer.
