Executive Product Summary for Process Tunnel Insulation Equipment

• The Process Tunnel is a new generation production line for manufacturing urethane, isocyanurate, phenolic foam core panels
• Process Tunnel uses an air film or air bearing to move the insulated panels through the pressure conveyor
• The air film or bearing provides rapid heat transfer, faster line speeds and unmatched accuracy of 0.010 of an inch
• In addition, the air bearing does not leave belt marks of a standard pressure conveyor
• The air film design allows for production of much thinner foam core panels than a standard pressure conveyor
• Smooth, flat and flexible substrate materials work best in the Process Tunnel
• The Process Tunnel line consists of multiple pieces of equipment working together for the manufacture of insulated foam core panels
• Polyurethane, isocyanurate, phenolic, or similar foam materials may be used in the production of foam core panels
• Chemicals are pumped from day tanks through a dispensing unit and into the mixing head mounted on a traverse
• The traverse moves rapidly across a laydown table to distribute the foaming chemical mixture
• The laydown table brings the top and bottom panel skins together with the expanding foam
• The foam insulation is spread across the bottom skin before it enters the process tunnel
• Inside the pressure conveyor the foam mixture expands filling the area between the two skins
• The length of the Process Tunnel depends on the chemical mixture used and the production speed needed
• Upon exiting the Process Tunnel, the foam panels are allowed to cool and stabilize on a roller conveyor
• If needed, the sides of the foam panels are trimmed with edge saws
• Then the insulated panels are cut to length
• At this point the individual foam core panels continue down a run out conveyor where they can be stacked manually or mechanically

• High production speed, better heat transfer, higher accuracy, and thinner panels
• On the fly, variable length production
• You can use a wide selection of smooth, flat, flexible panel skins
• Assured accuracy during production
• Flexibility of chemical formulations and production speeds

• Some examples of how foam core panels are used: exterior or interior walls, ceilings, floors, HVAC ducts, and backing for vinyl siding
