LEWCO Drum Heating Tunnels provide a means to heat individual drums that are not palletized, while also accommodating “first-in, first-out” product flow. These models also offer the potential for automated drum handling and integration into other processes. This model features integrated spill containment and is suitable for indoor use only. All models feature our signature all-welded steel, heavy-duty construction and simple, user-friendly controls. Each unit comes complete with a (3) year warranty and is fully assembled, wired, and tested prior to shipment.
