Minimum Pressure Accumulation Conveyor Systems.
A controlled, economical way to queue sturdy cartons and cases when light product-to-product contact is acceptable.

Both ACSI models use belt-driven live rollers and reduce pressure as products queue. Choose the duty class that fits the product and application.

Light Duty Minimum Pressure Accumulating
1-3/8″ roller belt driven. Gentle minimum pressure accumulation for light products.

Medium Duty Minimum Pressure Accumulating
1.9″ roller belt driven. Medium duty minimum pressure accumulation.

Minimum pressure accumulation is best evaluated by the conveyed product, acceptable contact, required queue length, operating rate, and conveyor geometry.
The 1-3/8″ roller platform is intended for lighter, consistently shaped cartons and cases that can tolerate controlled contact while accumulating.
The 1.9″ roller platform provides a medium-duty option for sturdier cartons and cases requiring controlled accumulation on a belt-driven live roller conveyor.
Products have stable bases, consistent shapes, and packaging that can accept light contact while queued. It can provide a straightforward, economical accumulation method.
Product separation matters, loads are fragile or variable, or downstream control requires independently released zones. Compare ACSI zero pressure accumulation conveyors.
Minimum Pressure Accumulation Questions.
It reduces driving force as products queue, allowing controlled light contact rather than full conveyor line pressure.
Sturdy, consistently shaped cartons and cases are typical candidates when their packaging can accept light contact.
Minimum pressure permits controlled contact. Zero pressure uses independently controlled zones to prevent pressure between adjacent products.
The 138CAP is light duty and the 190CAP is medium duty. Product size, weight, base, rate, queue length, and layout determine the final model.
U.S. Conveyor Manufacturer.
ACSI manufactures minimum-pressure accumulation conveyors for light and medium-duty applications where controlled contact is acceptable and zero-pressure accumulation is not required.
