Dorner Introduces ERT 250 Roller Conveyor

Dorner’s new ERT 250 precision edge roller pallet and tray handling conveyor provides efficient, non-contact zoning for medium & heavy load assembly automation applications. It features a clean, open roller design and is ISO Class 4 approved for cleanroom applications such as medical product and device manufacturing, assembly, and packaging.

The simple, yet robust, design provides long-term durability and ease of single point roller maintenance. The force to move product has almost no friction, which means less debris, dust, and chances for contamination.

Additionally, slip roller technology reduces the force by almost 75%, and the force to accumulate product with driven roller is less than that of belted conveyors. The rollers are driven by a patent-pending, energy efficient linear gearbox that gives customers added flexibility with motor positioning and zoning. This allows for zone and slip roller operation. Simply removing a lower gear creates independent zones.

The conveyor’s open design eliminates concerns of small parts or screws dropping into rollers and causing conveyor damage or jamming.

The ERT 250 is ideal for applications calling for pallet or tray handling, with no- and low-back pressure accumulation.

The non-contact zone control provides simplified traffic control that eliminates pallet stops and costly pneumatic valves. Conversely, slip rollers can be used for full-length runs with conventional pneumatic pallet stops. The rollers are easily accessible and can quickly be replaced without affecting the remaining portion of the conveyor.
