The spiral elevator from SpanTech is useful for cooling, curing and time delays. The product rests on the spiral chain and travels up or down at speeds up to 250 fpm. A variable frequency drive comes standard and no controls are needed. No pressure is applied to the device, so the elevator is suitable for delicate items such as butter. The unit handles a range of product sizes with no adjustments needed-the product group needs only to fit within the product-size envelope for each unit.
