When a disaster occurs, the support of disaster volunteers is essential for the recovery and reconstruction of affected areas. The aim is to assist those affected in returning to their normal lives as quickly as possible, with various disaster volunteer activities ranging from physical labor to administrative tasks and emotional support! Additionally, direct recovery support such as food distribution is also very important. We will introduce examples of how cool boxes are used during such disasters.

The Z Pack, which is active in various situations, has now been upgraded to a more powerful version! This product is recommended for those who frequently open and close their cool boxes and are concerned about temperature management of the items inside. Introducing the Z Pack 300L with a cooling unit, a foldable cool box equipped with a cooling unit. What’s different from the regular Z Pack? → There are three major differences! 1. High-power cooling system Normally, you would need to use the Z Pack in conjunction with ice packs for temperature management, but this product comes with a cooling unit, allowing you to store items in refrigerated or frozen conditions without the need for dry ice or ice packs! By simply using the Z Pack with the cooling unit, you can maintain a temperature range of -20 to +5°C, transforming a regular vehicle into a refrigerated or frozen one in no time! The high-power cooling system allows for quick cooling of the interior to refrigeration or freezing temperatures. *For more details, please see the related links below.

Introducing the "Z Pack," a large commercial cooler box available in stock that solves the issue of small sizes in foam and resin molded cooler boxes. We offer five sizes: 75, 90, 150, 240, and 300 liters. It excels when you want to transport a large quantity of refrigerated or frozen items at once. Made from high-quality domestically produced aluminum-coated fabric, it reflects direct sunlight and suppresses radiant heat. The core material is a 30mm thick insulation board used in construction materials, providing high insulation performance and durability. As reference data, we present the temperature test results assuming the delivery and storage of bottled beverages in an environment with an outside temperature of 40°C. By using cold packs in conjunction with the cooler box, it is possible to maintain a refrigerated state of 10°C or lower for 12 hours. Test conditions: Cooler box used: Z Pack 75L Cold packs used: 0°C grade cold packs, 2kg Contents: 10 bottles of 500ml bottled water Outside temperature: 40°C *For more details, please check the related links below.

We would like to introduce in detail the Heat Box W460SY, which was co-developed with Olsen Co., Ltd. Olsen Co., Ltd. is a general trading company engaged in the development and sales of industrial materials, shade products, and delivery products such as bento and pizza. It is also a "trading company with development capabilities" primarily focused on the textile industry! "We wish it could be done like this..." We take customer requests as important hints for manufacturing, and through Olsen's technical and development capabilities, along with their commitment (added value), we have realized "shapes that exceed expectations." Olsen has numerous achievements even with major companies. They boast over 10 years of experience in the delivery and heat retention industry, and they hold the number one market share in the pizza delivery industry! In fact, Olsen also has similar heat-retaining products. However, when customers inquired, many expressed concerns like, "I want it, but at that price, it's difficult..." This led to our collaboration, resulting in the birth of a heat box filled with Olsen's know-how and Sanyo's expertise! We were able to develop it at a price point that is competitive compared to conventional products!

When purchasing frozen souvenirs to take home or when requesting delivery through a co-op, dry ice is often included as a cold material. Due to the demand for staying at home during the COVID-19 pandemic, food delivery has also increased, and dry ice is being used for the transportation of COVID vaccines, leading to a rise in demand for dry ice. Dry ice is solid carbon dioxide that vaporizes at about -80°C, absorbing a large amount of heat in the process. The vaporized carbon dioxide is harmless and disperses into the atmosphere, making it highly convenient and easy to handle as a cold material for one-way applications or situations requiring ultra-low temperatures, without the need for post-processing. On the other hand, it sublimates and disappears if left alone, which can make storage challenging. In such cases, how about the new standard product "Dry Ice Cooling Box"? Our company has been providing custom-made boxes for dry ice delivery and storage to various customers for some time. Leveraging that expertise, we are developing products with a focus on ease of use, cooling performance, durability, and appearance. *For more details, we would appreciate it if you could check the related links below.

This time, we will introduce how to choose cold storage agents (cooling agents), their effective usage, and points to note. The term "cold storage agent" may not be very common, but the cooling agents used in low-temperature logistics for commercial purposes are referred to as cold storage agents. While there may not be a strict definition, I believe it is acceptable to understand that cooling agents and cold storage agents are the same thing. General cooling agents are often those that come with souvenirs for takeout or are used during activities like camping, and they are typically used at temperatures above 0°C. On the other hand, cold storage agents can be seen as more specialized cooling agents used to maintain temperatures below 0°C. There are various temperature ranges, capacities, and shapes available, and some of you may be wondering which one to use. Therefore, I am providing this introduction. For more details, I would appreciate it if you could refer to the linked page.
