Case Study: Miura City Hall, Kanagawa Prefecture - Introduction of "Ultra-Low Temperature Freezer Monitoring Solution" to Prevent Vaccine Waste ★ Monitoring of Freezer Temperature & Power Supply + Power Backup System (Note 1)
アイエスエイ
Utilizing the "Ultra-Low Temperature Freezer Monitoring Solution," a system that automatically monitors temperature and power abnormalities in freezers for storing COVID-19 vaccines, the Miura City Hall is implementing measures to prevent vaccine disposal. This initiative, which involves the introduction of a system that monitors both temperature and power, is one of the few of its kind in the country.
<Purpose of Implementation>
To monitor temperature and power abnormalities in freezers and ultra-low temperature freezers (deep freezers) storing COVID-19 vaccines, in order to prevent vaccine disposal accidents caused by power outages, equipment malfunctions, and human errors.
<Results of Implementation>
The system operated during power outages, allowing vaccines to be stored without compromising quality. Additionally, the vaccine storage environment (internal temperature and power abnormalities) can now be checked from smartphones and PCs, leading to reduced work hours for staff and improved operational efficiency.
<Freezers monitored by the system at Miura City Hall>
- One unit from Japan Freezer Co., Ltd.
- One unit from PHC Corporation
*For details about the system, please refer to the product PDF.
*For more information, visit our company website or the Ipros introduction page.
<Note 1> With a 270W freezer, the standard configuration provides 2 hours and 45 minutes of backup. In the maximum configuration (with two additional battery units), it can provide 5 hours and 5 minutes of backup.
Temperature increases inside the refrigerator can occur due to various factors such as human errors like incomplete door closures or unplugged power cords, power outages caused by lightning, and malfunctions of the refrigerator itself. At ISA, we monitor the important vaccines stored in the refrigerator 24/7, 365 days a year, with two solutions that monitor both temperature and power.
When the threshold is exceeded, email notifications and alert lights will be triggered, enabling efficient ventilation measures within the theater and helping to prevent sealing!
Measurement sensors (subunits) that do not require power are installed in each classroom, and measurement data is collected at the main unit in the staff room or management office. Since CO2 concentration and temperature and humidity data can be monitored remotely in bulk, measures to improve the indoor environment can be initiated immediately. By setting thresholds suitable for avoiding the three Cs and for the learning environment, the optimal timing for ventilation can be determined!
[Municipal Introduction] Monitoring temperature and power anomalies of deep freezers with emergency alerts! [Contributing to the prevention of vaccine disposal accidents with up to 5 hours of cooling! *1]
【Troubles and management measures that actually occur with ultra-low temperature freezers (deep freezers) for storing the COVID-19 vaccine】
■ Power outage
■ Plug disconnection
■ Forgetting to close the door
■ Equipment failure
■ Temperature anomaly
■ Circuit breaker
For power supply measures, a UPS (uninterruptible power supply) is connected to provide power in case of emergencies such as power outages. For temperature monitoring, a high-performance sensor unit is installed to automatically measure the internal temperature, and both systems will issue warnings and notifications via email or warning lights in case of anomalies.
<Applicable to both freezers and refrigerators>
Ultra-low temperature freezers for Pfizer vaccines (-75°C compatible deep freezers), low-temperature freezers for Takeda Moderna vaccines (-20°C compatible), and other freezers and refrigerators are also supported. (Can also be repurposed for refrigerators used for storage after thawing)
*Note 1: For a 270W freezer, with a standard configuration (one additional battery unit), backup for 2 hours and 45 minutes is possible. With a maximum configuration (two additional battery units), backup for 5 hours and 5 minutes is possible.

Double monitoring of temperature anomalies and power anomalies in cold storage for COVID-19 vaccines!! <Ideal for early detection and prevention of malfunctions and issues>
The management of vaccine freezers, such as ultra-low temperature freezers for Pfizer vaccines (-75°C compatible deep freezers) and low-temperature freezers for Moderna vaccines (-20°C compatible deep freezers), consumed human resources through regular inspections and checks of temperature loggers by opening and closing the doors.
At ISA, we have developed a monitoring system using the WD100 series, which utilizes LoRa wireless communication to monitor the internal temperature without opening the doors and to provide warnings and notifications in case of abnormalities. The system allows for remote monitoring via smartphones and PCs, and its retrofitting method makes it easy to install even in freezers that do not have built-in temperature loggers.
[COVID-19 Measures + Ventilation Promotion] Indoor Environment (CO2 Concentration + Temperature and Humidity) Monitoring Set (Main Unit + Subunits)! Up to 32 subunits can be connected!
The indoor environment monitoring set by Momoko and Ayaka from ISA (WD100 series) adopts the LoRa communication method for long-distance communication (LPWA), which is resistant to obstacles and enables low-power, long-distance data transmission. This allows coverage in areas where Wi-Fi and Bluetooth cannot reach. For example, when measurement sensors (sub-units) are installed in each classroom or in separate buildings on the premises (such as gymnasiums or club rooms), the main unit in the staff room or management room can collectively gather measurement data, overcoming conditions such as different floors or distances. Even in facilities where internet infrastructure is not established, environmental monitoring can be started immediately without the need for wiring work. Up to 32 sub-units can be connected to one main unit, and the sub-units come with a built-in battery that lasts for 10 years, requiring no maintenance. They can be installed in locations that do not allow for frequent removal, such as walls or high places, without the need for a power supply. Please feel free to contact us for any inquiries or concerns regarding environmental measurement and remote monitoring.
When the threshold is exceeded, email notifications and alert lights will be triggered, enabling efficient ventilation measures within the theater and helping to prevent sealing!
■Indoor Environment (CO2 Concentration + Temperature and Humidity) Monitoring Set
The configuration consists of a main unit + sub-units (with sensors included).
Up to 32 sub-units can be connected.
- Main Unit (WD100-S32/N32) Data Collection Communication Control Server
- Sub Unit (WD100-THC) Temperature and Humidity/CO2 Measurement Unit (with sensor included)
[Configuration Image]
Install the sub-units in locations where CO2 concentration and temperature and humidity need to be measured, and place the main unit in the office or management room. The main unit collects measurement data from each sub-unit. Since CO2 concentration and temperature and humidity data can be monitored remotely in bulk, measures for improving the indoor environment can be initiated immediately. By setting appropriate thresholds for avoiding crowded spaces and ensuring a comfortable environment, the timing for effective and efficient ventilation can be accurately grasped.
Measure indoor temperature, humidity, and CO2 concentration, and display it on a large LCD screen. Warn with three colors of light in stages and notify about ventilation via email or alerts!
The "Miharu-kun PRO <WD100-ENV-LCD>" features a large, highly visible LCD display that allows for easy monitoring from anywhere in the indoor space. It clearly indicates the timing for ventilation, contributing to cost reduction and energy savings. The secondary effects of ventilation also help prevent issues such as decreased concentration, drowsiness, and headaches, thereby contributing to a healthy indoor environment by addressing infection control and improving productivity.
