Power supply for cold chain delivery of premium chocolate.

Power supply for cold chain delivery of premium chocolate.

It has been adopted as a power source for deep freezers because the shipper requires temperature management and log submission.

Temperature management has become possible even with standard temperature transport vehicles, improving mobility. A portable power unit plus a battery bank can guarantee over 10 hours of sub-zero temperatures for small freezers. 【What is a cold chain?】 A distribution system that delivers products requiring low-temperature management in a refrigerated or frozen state to their destination. By storing and transporting goods in warehouses, containers, and trucks while maintaining low temperatures, deterioration is prevented. Delivery items are monitored with temperature sensors. Items requiring low-temperature management include a wide range of products such as pharmaceuticals, frozen foods, and fresh produce. *For more details, please download the PDF or feel free to contact us.

Power supply for outdoor events during food and drink events or markets.

Power supply for outdoor events during food and drink events or markets.

Adopted as a BCP measure for the event space commissioned by the city. It can be connected to electrical appliances that cannot be used with regular storage batteries, such as freezers and rice cookers.

The "HPP-2000/HBB-1000" is an off-grid power supply that can be used in places without electricity, just like a regular outlet. Typically, there is a shortage of outlets in the local dining area, and when using appliances like rice cookers, the circuit breaker trips. Therefore, it has been adopted to compensate for the insufficient capacity of the outlets. Additionally, it is also utilized as a power source for events such as regular markets held in the square. *For more details, please download the PDF or feel free to contact us.*
