There are several different types of Eagle Steam Tables, including Electric or Gas power for heating the water. Some models use water bath steam to then heat inserted food pans. Others use sealed wells, where the wells themselves transfer heat to food pans and their contents.
There are 2 wells, 3 wells, 4 wells, 5 wells, 6 wells steam table models available from Eagle. Note that Eagle's stationary steam tables are standard, but there are several portable models that come with casters.
