## Temperature-sensing Louver Utilizing Shape Memory Alloy Technology
Sahara Co., Ltd. (Headquarters: Ichinoseki City, Iwate Prefecture) announced the launch of the "Factory/Warehouse Heat Exhaust Eco-Louvre" on April 1st, a natural heat dissipation ventilation device that solves indoor heat build-up problems in large facilities such as factories, warehouses, and logistics centers.
In recent years, summer temperatures in Japan have continued to rise, and rising indoor temperatures have become a major issue in large-space facilities such as factories, warehouses, and logistics centers. In particular, the stagnation of hot air near the roof causes problems such as deterioration of the working environment, increased load on equipment, and increased air conditioning costs.
However, when introducing ventilation equipment or large fans, equipment costs and electricity costs increase, so in many cases, sufficient measures are not taken.
To address these issues, Sahara Co., Ltd. developed the "Factory/Warehouse Heat Exhaust Eco-Louvre," which dissipates heat using natural forces without consuming electricity.
## Natural Heat Dissipation System Utilizing Wind and Temperature Differences
This product adopts a natural ventilation method that creates airflow using external wind pressure and temperature differences inside and outside the building.
In factories and warehouses, warm air tends to stagnate in the upper part. By installing the Eco-Louvre on the upper walls of buildings, stagnant hot air is efficiently discharged to the outside, promoting indoor air circulation.
Since it does not use mechanical devices such as motors or fans, it has the features of not consuming electricity, requiring less maintenance, and suppressing running costs, making it possible to use it as an energy-saving ventilation measure.
## Temperature-sensing Opening and Closing Mechanism Utilizing Shape Memory Alloy
The "Factory/Warehouse Heat Exhaust Eco-Louvre" adopts a temperature-sensing opening and closing mechanism that applies shape memory alloy (SMA) technology, which Sahara Co., Ltd. has been researching and developing for many years.
Shape memory alloy is a metallic material that changes shape due to temperature changes. By utilizing this characteristic, a mechanism that automatically controls the opening and closing of the louvre according to the ambient temperature has been realized.
When the temperature rises, the opening expands to promote heat dissipation, and when the temperature drops, the opening closes, enabling natural ventilation according to changes in the internal environment of the building. Since no electrical control is required, it achieves both energy saving and high reliability.
This product is set to close at 5°C and open naturally at 25°C.
