[Installation Example Introduction] Walmart Experimental Supercenter

[Installation Example Introduction] Walmart Experimental Supercenter

We will introduce an installation example where the annual power consumption reduction is equivalent to the annual electricity usage of 60 households.

Here is an introduction to the installation example of the fabric duct system "DuctSox." This system is designed to evenly distribute air at low speeds only to the living areas where cooling and heating are needed, positioned at a low height. On the other hand, in the previous Walmart locations in the southern region, metal ducts and outlets were placed near the ceiling, requiring a cooling capacity of 450 tons. However, the Walmart experimental supercenter where the installation was carried out was able to manage with 380 tons. According to the designer, the annual reduction in power consumption amounts to 600,000 kWh/h, which is equivalent to the annual electricity usage of 60 households. [Installation Example] ■ Installation Location: Walmart Experimental Supercenter (McKinney, Texas) ■ Effect: Previously required a cooling capacity of 450 tons, but was able to manage with 380 tons. *For more details, please refer to the PDF document or feel free to contact us.

New factory "Ayase Plant" begins production.

New factory "Ayase Plant" begins production.

Manufacturing capacity is approximately 1.5 times greater! By having multiple manufacturing bases, we achieve BCP (Business Continuity Plan) response and stable supply.

Kyoudo Kaitech Co., Ltd. began construction of the new factory "Ayase Plant" on July 1, 2019, and started production on July 1, 2020. The construction of the "Ayase Plant" aims to address BCP (Business Continuity Planning) and the increasing demand for bus ducts. We will enhance productivity by establishing a continuous manufacturing line that only allows horizontal movement, which was impossible at the current Kanagawa Technical Center, and by semi-automating the sheet metal processing that is currently done manually. Our company offers a wide range of bus duct products, including the "E-BD type insulated bus duct" and the "F-PE type fire-resistant bus duct." We also handle the SS-T type low-pressure trunk line system "Shaft Star," which has been developed specifically for medium-sized buildings such as tenant buildings and apartments, as well as logistics warehouses. *For more details, please refer to the PDF document or feel free to contact us.
