Steam tables are available powered by either electricity or gas. Gas steam tables can be powered by natural gas, which is often piped into commercial kitchens, or propane, which is available in tanks for on-the-go operations. Electric steam tables usually have a cord and plug for easy installation. If you have access to both electricity and gas, you may consider checking local pricing to find the most cost-effective power source.
KaTom's selection of commercial steam tables includes units with as few as two up to as many as six wells, so you can find the unit that works best for the volume of food you will be serving. Each well holds a full-size pan, and can also accommodate certain fractional pans. Some units have accessories available such as adaptor plates and bars to allow the use of pans as small as one-sixth size, which can be useful for items like toppings and condiments.
Other options available on commercial steam tables include storage under the table, on a solid or slatted shelf, an attached cutting board for food prep, and a tray slide for buffet applications.
