Press Release: Transforming Worker Safety and Efficiency with RIGID’s AlphaCooler
RIGID is proud to share the success story of a prominent transportation equipment manufacturer that has implemented our AlphaCooler body cooling solution to safeguard employees, improve work efficiency, and prevent heat-related illnesses in high-temperature environments.
Discover how RIGID HVAC’s AlphaCooler transformed workplace safety and productivity at a leading transportation equipment manufacturer, preventing heatstroke and improving efficiency in extreme high-temperature environments.
1. Project Background
The customer operates a large-scale transportation equipment production facility. Their manufacturing process is continuous, spanning welding, assembly, and painting. In particular, the painting process involves workers using elevators that move up and down within a high-temperature painting booth. Due to the continuous nature of production, even a minor stoppage in one stage could disrupt the entire assembly line, impacting both productivity and deadlines.
During the painting process, workers are required to wear protective clothing and airline masks. While these measures protect their respiratory health and prevent inhalation of hazardous materials, the environmental conditions inside the painting booth remain challenging. Temperatures can exceed 40°C during the summer, and despite protective gear, workers’ upper bodies become drenched in sweat. The combination of high heat, humidity, and continuous movement exposes them to fatigue, heat stress, and increased risk of heatstroke.
Previous attempts to mitigate these issues included increasing the frequency and duration of breaks and providing vests with ice packs. However, ice packs typically melted within an hour, requiring significant preparation and labor. Moreover, using ice packs limited mobility and did not provide continuous cooling. These measures, while helpful, were insufficient to fully address heat-related risks.
Recognizing the critical importance of worker health and operational continuity, the company had already implemented several monitoring measures. This included tracking booth temperatures, measuring workers’ heart rates during breaks, and enhancing general health management practices within the facility. However, these initiatives did not fully prevent heat stress or fatigue, and a more robust solution was needed.

- Compressor Type: Brushless DC Rotary Compressor
- Cooling Capacity: 110–450 W (DC12V), 100–450 W (DC24V)
- Weight: 6.8 kg (15 lbs)
- Noise Level: ≤40 dB(A)
- Water Pump Flow Rate: 7.5 L/min
- Water Tank Volume: 145 mL
- Voltage Range: 9–19V (DC12V), 19–32V (DC24V)
2.2 Key Features
- Continuous Cooling: Unlike ice pack vests, the AlphaCooler provides sustained cooling without interruption, maintaining comfortable body temperature throughout the work shift.
- Flexible Hose and Lightweight Design: The hoses are flexible, and the overall design is lightweight, allowing easy donning and doffing during breaks. Mobility is maintained, which is critical for tasks such as climbing elevators and walking within the booth.
- Quiet Operation: With a noise level below 40 dB(A), the AlphaCooler does not interfere with communication or workflow, ensuring both comfort and safety.
- User-Friendly Control: Simple LED controls allow workers to monitor water temperature, ambient conditions, and compressor speed, enabling quick adjustments for personal comfort.
- Compact Form Factor: The unit’s compact dimensions (330 × 170 × 204 mm) allow it to be installed conveniently without obstructing workplace movement or other machinery.
2.3 Advantages
- Worker Safety: Significantly reduces the risk of heatstroke, especially in environments exceeding 40°C.
- Enhanced Productivity: Continuous cooling allows workers to maintain focus and stamina, reducing fatigue and increasing operational efficiency.
- Ease of Use: Minimal preparation and easy maintenance eliminate the logistical challenges associated with ice pack vests.
- Health Monitoring Synergy: When combined with existing heart rate monitoring and break management practices, the AlphaCooler contributes to measurable improvements in worker well-being.
3. Implementation and Operation
The implementation process of AlphaCooler was carefully planned to align with the facility’s workflow and safety requirements. Company leadership, including the president and factory manager, conducted on-site inspections to evaluate both environmental conditions and practical deployment scenarios. This ensured that AlphaCooler would meet the specific challenges of the painting process.
Workers wear the AlphaCooler as a body-cooling vest during the painting operation, particularly when using the elevator to move large parts between production stages. The unit’s lightweight design and flexible hose routing ensure that it does not interfere with walking, climbing, or other movements. The cooling effect covers the entire upper body, mitigating heat stress even while workers wear protective clothing and masks.
Operational Highlights:
Continuous cooling maintains optimal body temperature without the need for ice packs.
- The water pump provides a consistent flow rate of 7.5 L/min, ensuring uniform cooling across the torso.
- LED display allows monitoring of water temperature and compressor speed, providing real-time feedback.
- Quick connection hoses allow easy detachment and reattachment during breaks or shift changes.
- The AlphaCooler has been integrated seamlessly into the production workflow, allowing employees to work continuously without experiencing the fatigue or discomfort previously associated with high-temperature conditions.
4. Customer Feedback
Since installing the AlphaCooler, the company has reported zero cases of heatstroke in the current fiscal year—a significant improvement compared to previous years. Feedback from employees and supervisors highlights several notable benefits:
- Enhanced Comfort: Workers report that the vest cools the entire body evenly, creating a sensation of significant temperature reduction.
- Reduced Fatigue: Employees feel less drained after completing tasks, which allows for extended focus and sustained productivity.
- Elimination of Ice Pack Preparation: Continuous cooling eliminates the need to prepare or replace ice packs, saving time and reducing logistical complexity.
- Improved Efficiency: The ability to work continuously without interruptions has led to measurable productivity gains.
Quantitative Improvements:
Before AlphaCooler, workers’ heart rates during breaks ranged between 110 and 120 bpm.
- After implementation, heart rates stabilized around 100 bpm during similar conditions, indicating reduced physiological stress.
- The company plans to further optimize the AlphaCooler system by improving hose routing on the elevator, enhancing convenience and usability for all operators.
Overall, the customer’s experience underscores the effectiveness of AlphaCooler in addressing extreme workplace conditions while maintaining worker health and production efficiency.
