Found in all types of restaurants, from fast food to fine dining, a commercial deep fryer almost always runs on natural gas. Consuming anywhere from 60,000 to 100,000 or more BTU per hour, deep fryers for commercial use are far more durably built than home models. The main reason for this is that a commercial unit is likely to experience constant use during working hours, so their components need to be rugged. Made by a wide variety of restaurant supply manufacturers, including American Range, Imperial, Dean, Frymaster and Cecilware, commercial deep fryers can cost anywhere from $700 to $20,000, depending on their capacity, construction and operational features.
Smaller-Scale Commercial Deep Fryers
Lesser-priced commercial deep fryers typically feature a single or double basket oil vat with a cooking capacity of 10 to 40 pounds at once. Ideal for smaller restaurants, delis or food kiosks, they feature a combination of stainless and galvanized steel components, a mechanical thermostat and gas control mechanism with a regulator. Design features include a 3/4-inch gas line, a 200- to 400-degree range with temperature limit switch and a standing pilot light.
Heavy-duty commercial models will feature an all-stainless steel design, long-life elements and multiple fry pots each with a large capacity. Some models feature a built-in computer that automatically replenishes oil, runs logistical checks and improves the overall energy efficiency of the fryer.
