Care basically stainless steel boxes that can consist of one or several cooking compartments, making them highly versatile because each compartment can cook a different type of food. This makes them an ideal choice for cooking small quantities of food or for cooking a variety of different foods because you use only those compartments that are needed. Although pressure steamers are still in use, pressureless steamers dominate the market. For maximum flexibility, some compartment steamers offer both pressureless and pressurized cooking in a single unit.

- Pressureless (atmospheric) Steamers
> Cook without using pressure making them especially suited to frozen foods and on-line cooking.
> Cooking begins after the steamer defrosts the food.
> Cooking starts and stops automatically, without depressurization, any time the door is opened during the cooking process.
> Constant exchange of fresh steam allows dissimilar foods to cook at the same time because there is no transfer of flavors.
- Pressurized Steamers
> Achieves higher production by employing pressurized steam, which raises internal food temperatures 3°F above 212°F for every pound of pressure.
> Requires depressurization
