The HotRot 1811 unit consists of a steel/stainless steel u-shaped insulated hull, capped with fibreglass insulated lids. A stainless steel central tine-bearing shaft runs longitudinally through the u-shaped trough. This shaft is rotated periodically and provides mixing and aids aeration. Aeration is further enhanced by periodic air injection using a low-pressure system mounted external to the hull. 

​

This system is designed for situations where staff are undertaking other activities in the same general area (i.e. a waste management facility at a remote camp) or where a lower throughput is acceptable. The periodic feeding resulting from the use of a bin-lifter results in a reduced overall throughput. 

Like the HotRot 1206, the HotRot 1811 can operate successfully outdoors down to minus -20 C degrees  but again we would recommend placing the unit under cover when fitted with a bin-lifter feed system to provide weather protection to operators.
