Superheated Steam Mechanism

Superheated Steam is generated by instantaneously reheating 100°C steam. It contains approximately 11x more thermal energy than a conventional oven’s hot air.

Superheated Steam

Superheated Steam steam, Phreatic Explosion

Steam generated in the boiler is heated immediately by the high-temperature heater.

Normal Steam

Condensation Begins Immediately

Pooled water in the container gets steamed up by the heater.

How Superheated Steam Reduces Calories

When cooking meat, ultrafine and high-temperature Superheated Steam immediately envelops the meat. At this moment, the high thermal energy of the Superheated Steam quickly gets inside the meat and melts fats. This highly liquid fat is forced to the surface of the meat where it drips off together with water created by the difference in the meat's inner and outer temperatures. As a result, Superheated Steam achieves significant calorie reduction compared to typical pan cooking.

High Heat Oven / Grill

A heating element (ferrite rubber) is attached to the back surface.

3Triple Weight Sensor

Used to adjust the amount variance.



  • • Roast Chicken
  • • Steamed White Fish
  • • Baked Potato, etc

Food which needs continuous modest heating.



  • • Hamburg Steak
  • • Lasagna
  • • Fried Chicken, etc

Food which needs high grilling heat.

Auto cooking is a convenient function that first weighs the food then adjusts cooking temperature and time accordingly. The microwave heating element at the back of the tray allows food on the unit to be cooked at high temperature from the bottom.

Triple Weight Sensor

Triple Weight Sensor

About the Triple Weight Sensor

The Triple Weight Sensor weighs the food and automatically detects the optimum temperature and cooking time. The Sensor also uses a three-point measuring system to detect the food’s position, allowing precise focusing of microwaves for more efficient reheating. Even when temperature is high after use, auto cooking can still be performed.

2 to 4 Hamburger Patties

Reheat Two Dishes at the Same Time

The Sensor detects the weight of each dish and focuses more microwaves on the heavier one.

*A single serving of food is approximately 100g to 300g. As a rough guide, make sure the servings are within 0.7 to 1.3 the weight of each other. Use a setting that corresponds to the type of food you are reheating.
