The insulated overdoor "Ice Barrier" and "Ice Barrier 75" have been newly developed as decorative frames. The resin decorative frame can be used as is, which makes it less conductive to heat compared to traditional methods that involve wrapping with stainless steel, thereby reducing condensation. It prevents internal corrosion like that seen in traditional wooden decorative frames and suppresses the growth of bacteria, making it hygienic. Additionally, it reduces deterioration due to corrosion, thereby lowering maintenance costs associated with replacements and repairs. *For more details, please refer to the leaflet.

"KOSMOS" (Kongo Smart Multi Monitoring System) is a remote monitoring system for doors that utilizes IoT technology. It shares data with KMS (Kongo Maintenance Support System) regarding the operational status of doors, the number of openings and closings, as well as the surrounding temperature and humidity. This enables automatic recording and monitoring of temperature and humidity necessary for HACCP compliance, and allows for the management of the operational status of truck berths, facilitating efficient planning of inbound and outbound shipping operations. By reducing the opening time of doors to minimize cold air leakage, it helps lower electricity costs and contributes to energy-saving effects. ★ Awarded the Special Prize in the Service & Solution category at the MCPC Award 2020 ★ At the MCPC Award 2020, "KOSMOS" received the Special Prize in the Service & Solution category. The MCPC Award 2020 recognizes cases that have achieved results in "business efficiency," "performance improvement," "customer satisfaction enhancement," "promotion of social contribution," and "advanced mobile utilization" through the introduction of mobile systems in the IoT/AI field. It is held annually to promote the further dissemination of mobile solutions and IoT/AI systems.

The dock shelter consists of a pad wrapped in a sheet made of polyurethane foam, but if the sheet gets partially torn, the tear can widen, causing the foam inside to be scraped off, or the edge of the sheet may get caught on a truck, potentially detaching the entire dock shelter. To prevent this, a new sheet is placed over the pad to reinforce it and maintain safety. 【Benefits of Dock Shelter Reinforcement Repair】 ● It reinforces the damaged areas of the pad. ● The appearance is restored to like-new condition. 　(※ The metal parts remain as they are.) ● It is more cost-effective and eco-friendly compared to replacing the pad with a new one, as it generates minimal waste. 　(※ Depending on the condition of the underlying structure, pad replacement may be necessary.) ● An optional heat-insulating sheet can also be included. ● Methods can be chosen according to the budget. ■ For more details, please download the materials and take a look.
