NE-2180C, NE-2180, NE-3280 specifications

Panasonic's commercial microwaves, including the NE-3280, NE-2180, and NE-2180C, are designed to meet the demanding needs of the foodservice industry. Each model is engineered to ensure optimal performance, efficiency, and durability, making them ideal for restaurants, cafes, and catering services.

Starting with the Panasonic NE-3280, it features a powerful 1800 watts of cooking power. This industrial-grade microwave offers a spacious 0.9 cubic feet interior, allowing for larger dishes and more significant quantities of food to be heated at once. The NE-3280 is equipped with a user-friendly touch control panel that provides easy access to multiple power levels and cooking times, which can be stored in memory for quick recalls. A key feature is its inverter technology, which delivers a steady stream of power for even cooking and defrosting, ensuring food retains its texture and flavor without overcooking.

Next, the NE-2180 model also showcases cutting-edge inverter technology but with a slightly lower wattage of 1,200 watts. This model maintains a compact design while providing a substantial 0.8 cubic feet of cooking capacity. It's tailored for smaller kitchens or operations looking for efficiency without compromising quality. The NE-2180 comes with programmable menus enabling quick selection of common cooking tasks, improving speed during busy service periods. Furthermore, the stainless-steel exterior makes the unit easy to clean and resistant to wear over time.

The NE-2180C variant is similar to the NE-2180 but is designed with specific features for enhanced versatility in food preparation. It includes a reliable cooking timer and a convenient one-touch control for reheating items quickly. The NE-2180C also sports a robust construction tailored for high-volume use. All three models boast a design that enhances safety with features like a cooling fan to prevent overheating and a child safety lock.

In summary, Panasonic's NE-3280, NE-2180, and NE-2180C microwaves represent a blend of innovation, reliability, and versatility. Each model is geared toward improving efficiency in commercial kitchens while ensuring the quality of heated food.
