ASI's dryers are used in virtually every industry from adhesives and release liners to home goods and construction materials. If the product is made on a flexible web or a continuous process, we can design a system to dry, cure, or cool it. The industries we serve include:
Adhesives, Tapes, & PSAs
Three-zone flotation drying system for a specialty coatings, adhesives, and tape line. The dryer has an external split-hood retraction system that uses screw jacks to move the upper enclosure section 18 inches upwards for access to the dryer’s interior for web-up, cleaning, and maintenance.
Two-zone impingement drying system for an automotive foam product. System utilizes electric platens controlled via SCRs below the web and heated air above the web. A retraction system allows for access to the interior for web-up and cleaning.
Battery Electrode & Separators
Three-zone, flotation drying system with integrated plenum for a battery electrode coating line on an aluminum or copper foil web. The drying system has the following components to reduce contamination: electric heaters; HEPA filters for the makeup air; prefilters on the recirculated air; and drain ports at the bottom of the dryer to allow for pressure washing and cleaning.
This is the gear side of an almost 200-foot long dryer that features nine separate heating zones. It utilizes both counterflow and co-flow air and is belt supported. Separate heating zones provide versatility and fine-tuning of the drying rate for this cast coating line.
Six-zone drying system for an aqueous coating line that utilizes hole bars and drag bars. Dryer features 304 stainless steel construction, electric heat, HEPA filters in makeup and recirculated air, and mounting provisions for CO2 fire suppression nozzles within the dryer enclosure.
Six-zone through-air drying system for manufacturing shingle construction materials. Dryer utilizes a steel mesh belt and includes a belt return path and belt tensioning system. System includes web entry and exit roll stands.
Diapers & Personal Care
Three-zone flotation drying system for diaper material. Dryer has an external retraction system for web-up and cleaning.
Three-zone flotation curing and drying system for manufacturing electrical components for hard drives. System has stainless steel interior construction, door access, electric heat sources, and a pneumatically actuated internal retraction system.
EPDM & Rubber Webs
Three-zone arched roll-support dryer for a 200 inch wide EPDM web. Dryer is sized for both water and solvent based coatings and features natural gas plenums, split-hood retraction, and our standard Allen Bradley Compact Logix PLC controls package.
Fabrics & Textiles
Three-zone catenary or inverted arch drying and curing system that is used to dry a woven fabric web. This dryer is designed for a 6-inch web sag at the center of zones 1 and 2 and roll support in zone 3. Because the web is coated on both sides with a volatile coating that must be dried slowly with no contact, the dryer was designed for the web to create a catenary web inside the dryer.
Five-zone through-air drying system for a fiberglass mat line. The fiberglass web is supported by a conveyor belt over idler rolls and the system includes a belt return tunnel below the dryer. The dryer is over 11 feet high, 80 feet long, and can deliver air volumes of over 100,000 acfm at 600 degrees Fahrenheit. ASI also supplied web entry and exit roll support stands with a vacuum table to provide a transition into and out of the dryer.
Films & Foils
Three-zone drying system for a foil web material used to manufacture solar cells and solar panels. System utilizes electric heat and is comprised of a heat zone, cure zone, and an ambient air cooling zone. Doors provide access to the interior for web-up and cleaning.
Two-zone flotation drying system for nonwoven reverse osmosis filter media. System has low NOx gas burners for the heat sources and airfoils below the web for web flotation and controlled drying.
Two-zone flotation drying system for a flexible packaging line. Dryer features external split-hood retraction and windows with back lighting for web viewing.
Medical & Pharmaceuticals
Three-zone flotation drying system for a paper-based web on a pharmaceutical line. The dryer is constructed with an all stainless steel interior, class IV polished welds, and steam coils for heat to prevent product contamination.
Four-zone arched roll support drying system for a nonwoven PTFE product used for pressure sensitive adhesives (PSAs), gasketing, and sealing material. System was controlled using a PLC with distributed I/O and included the support legs to provide a specific web pass height.
Paper & Plastic Webs
Single zone flotation drying system for drying gravure printing on a paper web. Dryer features a clam-shell retraction system and integral plenum design.
Three-zone flotation drying system for release liners and PSAs. Dryer utilized our BW-style flotation airbars for maximum web stability and maximum heat transfer. Recirculated air is filtered through HEPA filters located prior to natural gas burner heat sources.
Reverse Osmosis Media
Three-zone flotation drying system designed to dry a polysulfone coating on a polyester web for reverse osmosis membranes. This dryer utilizes ASI’s hole AirBars in the first zone to limit drying and reduce streaking on the web. The upper hood has a retraction system that allows for 18” of upward travel allowing for easy access to the dryer’s interior for web-up, cleaning, and maintenance.
Two-zone flotation drying system installed on a 65” wide silicone release coating line. The dryer utilizes ASI’s silicone plenum design that greatly minimizes or eliminates silicate dusting that can cause product contamination in the supply air when silicate particulates reach an elevated temperature.
