Located in Green Bay, Wisconsin, ASI has been an industry leader in providing custom drying, curing, and cooling solutions to manufacturers in the US and abroad since 1986. We specialize in forced air convection drying and curing solutions for the converting, inline, roll-to-roll and continuous process industries. Our systems employ a variety of web transport and heating methods, including air flotation, roll-support, through-air, and infrared (IR) supplementary heat. 





We have designed and built inline drying systems as short as 36 inches to over 200 feet in length for widths ranging from 4 inches to over 200 inches wide. Web speeds vary from less than 20 fpm to almost 2,000 fpm. Some of the industries we serve include:

  • Adhesives, tapes, & PSAs

  • Automotive products

  • Battery electrode & separator lines

  • Coating & casting lines

  • Construction materials

  • Diapers & personal care products

  • Electrical components

  • EPDM & rubber web lines

  • Fabric & textile lines

  • Fiberglass mat lines

  • Film & foil web lines

  • Filtration media lines

  • Flexible packaging lines

  • Hydrophilic cast coating lines

  • Medical & pharmaceutical lines

  • Nonwovens

  • Paper & plastic web lines

  • Release liners

  • Reverse osmosis media

  • Silicone-based coating lines

Peripheral Components


We also design and fabricate an array of peripheral components to meet our customers' requirements and facilitate getting their line installed and operating as quickly as possible: ​

Manufacturing at ASI
ASI Building

ASI's 65,000 square foot manufacturing facility employs over 30 highly skilled machinists, welders, electricians, technicians, and tradespeople. From metal fabrication, welding, and electrical dress out, to painting and system testing, our facility can accommodate the fabrication of any size dryer a customer requires. Our multiple manufacturing bays and cranes allow for several orders to be worked on simultaneously to meet our customers' needs. 

ASI Manufacturing Facility

ASI's dryers are designed, engineered, and manufactured solely in Green Bay, Wisconsin and we ensure strict compliance with all applicable codes and regulations, including NFPA, FM, GE GAP requirements, and OSHA safety standards.


ASI adheres to a rigorous quality control process to ensure that everything we manufacture, wire, and program performs as designed and as required by the customer. When you buy an ASI drying system, you can be confident that you are getting a quality product made in the US that will accomplish your drying needs.

ASI's Technology


ASI is located in Green Bay, Wisconsin, and has been designing and manufacturing custom drying solutions since 1986.



ASI's vast experience in designing and manufacturing custom drying solutions, as well as its proprietary modeling programs and patented air and web handling technology, means that our customers always get a drying system specifically designed for their application that performs as required while optimizing heat transfer and efficiency. ASI's modeling program uses heat and mass transfer equations, empirical data, and lab trials to accurately predict how a coating will dry as it travels through a dryer. In addition, ASI has developed over two dozen AirBar designs and has been granted over twenty patents related to AirBars and drying technology.

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.

ASI's AirBar mounting system keeps maintenance downtime at a  minimum by allowing for easy removal and reinstallation. This is accomplished by making the AirBars interchangeable and thus, eliminating the need to match-mark each AirBar to a specific location. Removal and installation is further eased by our one or two bolt-mounting system.

ASI's flotation dryers utilize our air handling technology through offset AirBars and return air baffles to create a sine wave with the web that promotes web stability and reduces edge flutter.​

Our AirBars are mounted on tapered headers engineered to deliver air that is of uniform temperature and volume. Header feed legs are designed to provide even air distribution in both the machine and cross-machine directions. This attention to detail ensures that ASI dryers offer predictable, consistent, and streak-free drying.

ASI's AirTurns

ASI's AirTurns allow for web maneuverability and directional changes without web contact. Our dryers can be designed with AirTurns that allow for multiple web passes to conserve space and accommodate space restrictions.

ASI's Engineered Efficiency

ASI dryers are thoughtfully and intentionally designed with the following features to enhance performance and efficiency:

  • minimum through-metal for avoidance of localized hot-spots;​

  • a minimum of four (4) inches of high-temperature industrial insulation to reduce heat loss, increase efficiency, and reduce operating costs;

  • internal expansion joints to allow for thermal expansion;

  • premium efficiency supply and exhaust fan motors;

  • one or two bolt mounted and interchangeable AirBars for ease of removal, reinstallation, and maintenance;

  • return air baffles to reduce cross-machine air flows and avoid web disruption while maintaining a consistent drying profile;

  • ASI's exclusive twisted Z-clips that are welded between the inner and outer walls to create spacing for insulation while allowing for metal expansion in all directions;

  • gasketed access doors for easy access to the interior enclosure that are designed with a slotted heat trap to reduce heat loss.
