DENBA＋2.0 & 3.0 / Fresh Pro

One of its key advantages is that it can be added onto existing equipment.
This significantly reduces costs compared to replacing the whole unit.

DENBA Technology

DENBA technology is a next-generation freshness preservation technology that activates water molecules in food to maintain peak seasonal taste. By simply installing a compact device inside existing refrigerators or freezers, it exerts powerful freshness-preserving effects. Premium fruits like grapes and Shine Muscat remain juicy and delicious even after two months. Meat processors report up to a 95% reduction in drip loss during thawing of meat and fish. It enables freezing without cellular damage even in standard freezers. This cutting-edge technology is rapidly gaining traction in household refrigerators, commercial units, transport trucks, and shipping containers worldwide.

By causing water molecules to vibrate, food can be stored in subzero temperatures between 0°C and -4°C without freezing.

Usually, when water freezes, its volume expands and damages the cell walls of food. DENBA+ prevents this damage, keeping food fresh during storage.

■ The electric field is formed in all 360° directions from the discharge plate (mat)

DENBA technology is a system that helps preserve food freshness by applying subtle vibrations to water molecules

It generates an electric field with a radius of approximately 1 to 1.5 meters from the discharge plate (mat)

Even without direct contact with the plate, it can cause micro-vibrations in the water molecules within the electric field (space)

◆ Acts on water molecules within the electric field space

◆ Effects can be achieved even without touching the mat

High-quality “Refrigeration”, “Freezing” and “Defrost”

“Refrigeration”

Protects freshness from within by activating food cells with Extremely Low Frequency (ELF) technology.
The world’s first safe ELF technology has realized longer-lasting food freshness.

“Freezing”

Freezing at -18 °C to -25 °C minimizes structural damage to food cells, enabling high-quality preservation.
From this freezing method, it has become possible to maintain texture, flavor, and overall freshness for a longer period than ever before.

“Defrost”

Compared to conventional defrosting, this technology significantly reduces drip loss — by up to 95% — helping deliver fresher quality and greater customer satisfaction.
