KOYAMA CO., LTD. Product Lineup

In the manufacturing industry, temperature management in the work environment significantly affects product quality maintenance. In particular, working in high temperatures can lead to decreased concentration and health issues, increasing the risk of defective products. Therefore, it is important to maintain worker comfort and ensure stable quality. Our W Cooling Fan contributes to quality maintenance by suppressing temperature rise in the work environment through a combination of fan airflow and double cooling plates. 【Usage Scenarios】 - Work in factories with high temperatures - Precision tasks that require quality control - Long hours of outdoor work 【Benefits of Implementation】 - Reduction in perceived temperature for workers - Improved quality due to maintained concentration - Decreased risk of heat-related illnesses

In the construction industry, work is often required in harsh environments, such as long hours outdoors or near heat sources. In such situations, workers' body temperatures can rise significantly, increasing the risk of heatstroke. There are growing concerns that general cooling vests may provide airflow but not sufficient cooling. Therefore, the W cooling fan equipped with a cooling plate enhances worker comfort and strengthens heatstroke prevention through a dual cooling effect of airflow and the cooling plate. 【Usage Scenarios】 - High-altitude work outdoors - Work near heat sources - Long hours of heavy machinery operation - Material transportation during summer 【Benefits of Implementation】 - Suppression of workers' body temperature rise - Reduction of heatstroke risk - Improved work efficiency through sustained concentration - Fatigue reduction

【Fan-assisted airflow + Peltier cooling plate】 Due to the recent extreme heat, there has been an increase in feedback that "the air comes in, but it's not cool" with typical cooling clothing. Therefore, we have developed a dual cooling fan equipped with a cooling plate. 【Double cooling sensation from fan airflow and cooling plate】 STEP 1: The air blown from the fan evaporates sweat, lowering body temperature through evaporative cooling. STEP 2: The cooling plate lowers the temperature of the air circulating inside the clothing, enhancing the cooling effect. STEP 3: The cooling plate directly contacts the body, allowing you to feel the coolness instantly.

It is suitable for harsh usage conditions such as precision machinery, marine and chemical fields, and ultra-low temperature environments. Its specific gravity is 4.51, achieving about 60% of the weight of iron. In addition to preventing magnetic interference due to its complete non-magnetic properties, it exhibits excellent corrosion resistance that surpasses stainless steel due to its strong oxidized surface, making it resistant to seawater and chemicals. 【Convenience of Procurement】 During the prototype and verification stages, arrangements can be made immediately from just one piece. When transitioning to mass production, we utilize our unique procurement routes as a specialty screw trading company to efficiently source equivalent products that meet design specifications. We aim to optimize costs and delivery times.

We have achieved "cooling the entire body" which was not possible with previous heat countermeasure products. When you sit inside the box, a breeze blows from the back, and cool air hits your neck just right. The cool air is about 5°C, providing a refreshing sensation similar to that of a refrigerator's chilled compartment. Compared to conventional localized cooling methods, it effectively cools the body. Additionally, it automatically stops after 20 minutes to prevent excessive cooling. There is no need for installation work, so it can be used immediately, and it is suitable for both indoor and outdoor settings. The electricity cost is approximately 16 yen per hour! Its energy-saving performance is about half that of a spot air conditioner. We have demo units available.

To maintain a safe working environment, it is important to manage the health of workers. In particular, in recent years, there has been a trend of prolonged extreme heat and revisions to labor safety and health regulations, leading to a demand for companies to strengthen their heatstroke countermeasures. "Canary Plus" is a wristwatch-type wearable device that detects the risk of heatstroke based on changes in core body temperature. An alarm sounds when the core body temperature approaches 38°C, notifying of the risk of heatstroke. 【Usage Scenarios】 - Managing heatstroke risk during work at construction sites - Compliance with mandatory heatstroke countermeasures - Strengthening safety measures on-site 【Benefits of Implementation】 - Reducing the risk of accidents due to heatstroke - Improving health management and safety for workers - Strengthening safety measures as a company

• Other measurement, recording and measuring instruments

Summer factories, construction sites, and logistics sites. "I thought it would be fine for now." This complacency is leading to an increase in serious accidents and withdrawals. In recent years, especially with the prolonged heat waves and the trend of revising labor safety and health regulations, companies are being urged to strengthen their measures against heatstroke. "Canary Plus" is a wristwatch-type wearable device that detects heatstroke risk based on changes in deep body temperature. An alarm sounds when the deep body temperature approaches 38°C, notifying you of the risk of heatstroke. Additionally, - No charging required (single-season use) - IP67 dustproof and waterproof - Lightweight design at approximately 30g - Easy-to-wear wristwatch type are features that make it user-friendly for on-site use. Demonstration tests have also been conducted with the Tokyo Fire Department, confirming the effectiveness of the algorithm in high-stress environments.
