The AccuTemp S34403D090 SGL Steam'N'Hold™ Boilerless Floor Model Steamer is a stand-mounted electric convection steamer designed to hold three pans. It operates on 440v/60/3-ph power at 12 amps and has a power output of 9kW. Unlike conventional convection steamers, this steamer does not use fans to distribute heat. Instead, it utilizes AccuTemp's patented vacuum technology to remove air and allow steam to directly contact the food for more efficient cooking. This unique cooking mode cannot be replicated by other convection steamers. The steamer is connectionless, eliminating the need for plumbing for water and drain lines. It features a 3-gallon water reservoir that needs to be manually filled. The unit can use any potable water without the need for filtration or treatment, including hard water. AccuTemp provides a lifetime service and support guarantee, regardless of water quality. Standard features of this commercial floor model steamer include a 90-minute timer, heavy-duty door, power on switch, field reversible door, front-mounted drain valve, and no water or drain line requirements. It also comes with a 5-foot power cable and an L16-20P plug for easy connection to a 20 amp breaker. Optional features include a drain kit, marine package, military package, 180-minute timer, left-hinged door, perforated cooking shelf, one-year extended warranty, and more. The steamer is made of durable reinforced 14 ga. 304 stainless steel and is certified as a variable temperature holding cabinet. It is designed for efficiency and faster cooking, thanks to its patented vacuum technology and low temperature steam cooking mode.
