Product & Solution Certification

DENBA helps support
crew health and
the enjoyment of meals.

During long periods of service at sea, meals are one of the few daily pleasures for crew members and an important part of health management. On long ocean voyages, it is difficult to keep perishable fresh foods such as vegetables and fruit for extended periods, so frozen and processed foods tend to become the main options in the latter half of the voyage, reducing menu variety and making meals less balanced.

The marine food freshness preservation system “DENBA⁺ Marine” has obtained Product & Solution Certification under “Innovation Endorsement,” a certification service for innovative technologies provided by ClassNK.

Crew Feedback

  • We appreciate this wonderful invention from DENBA.

    The DENBA system installed on this vessel has been highly effective and has greatly helped keep fruits and vegetables fresher for longer. My crew and I monitor it daily and are satisfied with the results.
    We appreciate this wonderful invention from DENBA.

    Captain

  • Still fresh even after 30 days onboard!

    Even after being stored onboard for 30 days, the vegetables still look fresher than before.
    Our chief cook is very satisfied with this system.
    *We received this message from the captain along with photos of the fresh vegetables.

    Chef

  • The DENBA system works well for most vegetables and fruits.

    DENBA can also be used on other vessels and offers clear advantages. When vegetables and fruits are supplied fresh by the vendor, we have observed an impression of 5 to 8 additional days of storage life.

    Crew

  • We were impressed by how well it maintained the freshness and quality of vegetables and fruits!

    After installing DENBA+ in our provision room, we were impressed by how well this technology maintained the freshness and quality of vegetables and fruits. Vegetables and fruits purchased in Naoshima, Japan on January 31, the same day DENBA+ was installed on the vessel, have retained more than 95% of their freshness, appearance, and taste to date.

FAQ

How long can DENBA products extend the freshness of fresh foods?

Because the type of vegetables and fruits, as well as their freshness and quality at the time of purchase, vary each time, it is difficult to provide a specific freshness-extension period. However, there have been cases where dishes using fresh vegetables could still be served after four weeks.

How long can DENBA products extend the freshness of fresh foods?

①Metal containers may reduce the DENBA effect, so please move food into plastic or cardboard containers. ②If the discharge mat touches metal, the discharge effect may weaken. Do not allow metal to touch the mat. ③To help prevent moisture evaporation from vegetables and fruits, close the lid of the cardboard box and cover it with cloth if possible. ④Set the storage temperature to around 2–5°C to help suppress bacterial growth and slow spoilage.

Do you have ROI data showing reduced food waste or extended shelf life from improved freshness after introducing this product?

This product is primarily designed to improve the QOL of vessel crews, so we do not have ROI data.

What technical guidance or support is available after purchase?

Operation is very simple: leave the power on 24 hours a day. If you have any questions, please contact us through your distributor, and we will answer as fully as possible based on our past experience and results.

Are there any additional costs after purchase?

No costs are incurred other than electricity. Electricity costs are about 100 yen per month. However, if consumable items such as mats are damaged, those items will need to be purchased again.

Have you obtained any certifications other than ClassNK?
Have you obtained any region-specific local certifications overseas?

In addition to ClassNK certification, this product has obtained PSE, CE, RoHS, and VDE certifications. We have not obtained region-specific local certifications for particular overseas areas.

Is this product recyclable?

This product is not designed with recycling as a premise.

Are there any costs required for introducing or installing the product?

For shipment from the manufacturer within Japan or mainland China, a shipping fee of 3,000 yen will be charged. If our technicians install the equipment, an installation labor fee of 30,000 yen plus actual travel expenses for two people will be charged.

What is the shipping cost when shipping outside Japan?

Overseas shipment can be arranged through the courier specified by the customer, such as DHL, FedEx, or EMS. Shipping costs vary depending on the timing of the courier quotation, but a paid receipt from the courier will be attached when actual costs are billed.

What is the product warranty period?

The warranty period is one year after purchase.

Technology that vibrates water molecules is also used in sonicator devices. Does this product use the same technology?

Sonicator devices and this product use different frequencies. This product uses an extremely low frequency of around 50–60 Hz to vibrate water molecules in food without damaging food cells, helping maintain freshness.

Can you provide contact information for existing customers who can share feedback about the product?

We are sorry, but we do not disclose customer information.

What is included with the product besides the main unit?

The following items are included with the product.

①Main unit
②Three discharge mats
③One high-voltage cable (5 m)
④One power cable
⑤One voltage detector
⑥User guide
⑦Instruction manual
⑧DENBA sticker
⑨USEFUL TIPS
⑩30 attachments
⑪Waterproof receptacles (one male and one female)
⑫Extension high-voltage cables (one 5 m and one 2 m)
⑬One Y-connector

How much space is required to install the discharge mats, and what is the amperage?

Each mat measures 126 cm × 66 cm. The discharge range extends about 1 m in all directions from the mat, so when placing a second mat nearby, it can be set up to about 2 m away.
Please arrange the three mats so they can be attached to the wall or hung on a shelf.
The amperage of this product is 0.03A.

An ozone generator is installed in the vessel’s refrigerated storage room.
Is it okay to add DENBA MARINE?

In conclusion, there is no problem using the two products together. They have different characteristics. An ozone generator sterilizes bacteria that have already occurred, while this product helps suppress bacterial growth through lower storage temperatures. Therefore, the products do not interfere with each other.

How should the product be cleaned?

Both the main unit (IP45) and mat (IP56) have waterproof performance. However, detergents often cannot be used in chamber rooms, so please clean with water only.

Can the product be transferred to another vessel due to vessel sale or similar reasons?

This product can be transferred to another vessel. However, it must be installed on a vessel with the same voltage. Also, when removing the mat from the wall during transfer, the double-sided tape on the attachments cannot be reused. If additional attachments are needed, please contact your distributor for the parts cost.

How long is the product life?

Although it depends on the usage environment, the product has durability comparable to ordinary home appliances. It does not use any moving parts such as motors or fans, which are common causes of failure in general home appliances.
