LEWCO Drum Heaters are the most common and economically priced solution for elevated temperature storage and heating. Low Profile models are constructed with a 12 gauge steel plate floor that allows for convenient loading and unloading with a pallet jack or drum dolly. Due to the plate floor design, this model 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.
