How does a reefer monitoring system improve productivity

A remote reefer monitoring system offers real-time tracking of temperature and humidity levels for perishable goods throughout their journey, including transportation and storage at ports. This system ensures greater visibility and control over the supply chain, allowing operators to promptly address any deviations from optimal conditions. By maintaining the ideal environment for sensitive cargo, such as fresh produce, pharmaceuticals, or seafood, the system reduces spoilage risks, enhances product quality, and minimizes financial losses. Additionally, the data gathered can be analyzed to improve logistics planning, boost operational efficiency, and strengthen customer trust by consistently delivering goods in perfect condition.

FDA Compliance Made Simple
How the system works

How It Works

1. Solar Powered Wireless Temperature SensorsThese small, self-powered sensors are placed inside the refrigerated trailer. They continuously monitor the environmental temperature and optional humidity and send data wirelessly. Communication is done via BLE (Bluetooth Low Energy) or optional wired digital temperature sensors
2. Active RFID GatewayPiccolo Gateway device is mounted outside or on the trailer. It receives temperature data from the BLE sensors inside the trailer. communicates with sensors from up to 150ft (50m) away.
3. Data Transmission to the CloudThe Piccolo gateway transmits the collected data via 4G LTE cellular network. The data includes:Pickup/drop-off locationsReal-time temperatureLast known locationDate & time stamps
4. Fleet.Net Cloud PlatformAll transmitted data is centralized on our powerful Fleet.Net cloud platform. Dispatchers or managers can access the platform to:Monitor trailer location in real timeView temperature logs for cold chain complianceReceive alerts for temperature excursions or route deviations

FAQs

Reefer temperature monitoring - Frequently Asked Questions

What is a reefer monitoring system?

A reefer monitoring system tracks and reports real-time temperature, humidity, and operational status of refrigerated containers (reefers). It provides alerts if conditions deviate from set parameters, ensuring cargo quality and compliance.

How to monitor reefer container temperature?

You can monitor reefer temperatures remotely using telematics solutions with sensors that transmit data via cellular or satellite networks. Real-time temperature and alerts are accessible through web-based platforms or mobile apps.

How often should I check the reefer temperature?

For optimal cargo safety, temperature should be checked at least every 4 hours. Continuous remote monitoring systems can provide automated checks at more frequent intervals (typically every 5 to 15 minutes).

How often should a reefer be serviced?

Routine servicing should occur every 1,500 to 3,000 operating hours or approximately every 6 months, whichever comes first. This typically includes inspection, coolant checks, compressor maintenance, and electrical system evaluations.

What is the normal temperature for a reefer?

Typical reefer temperatures range between -30°C (-22°F) and +30°C (+86°F), depending on the cargo. For most refrigerated foods and pharmaceuticals, temperatures between 2°C (35.6°F) and 8°C (46.4°F) are common.

What temperature should a reefer container be set at?

Reefer container temperature settings depend entirely on the cargo. Examples: Fresh fruits/vegetables: +2°C to +8°C (35.6°F to 46.4°F) Frozen meats/fish: -18°C to -25°C (-0.4°F to -13°F) Pharmaceuticals: +2°C to +8°C (35.6°F to 46.4°F)

What is the maximum temperature for a reefer container?

Maximum allowable temperature typically is around +30°C (+86°F), though cargo-specific guidelines should always be followed.

How do you check a reefer container?

Conduct visual inspections for damage, leaks, or corrosion. Verify setpoint temperatures, air flow, and humidity levels. Use a monitoring system to confirm compressor status, alarms, and sensor accuracy. Ensure reefer doors seal properly and insulation integrity is maintained.

What is the average reefer rate per mile?

Average reefer transport rates per mile range approximately from $2.00 to $3.50 in the U.S., but can vary greatly depending on distance, cargo, region, and market demand.

How many hours is a reefer good for?

A well-maintained reefer typically lasts between 15,000 and 25,000 operating hours (approximately 7–12 years), depending on usage intensity, maintenance schedules, and environmental conditions.

How do you troubleshoot a reefer unit?

Check alarms or error codes displayed on the unit. Inspect electrical connections, battery, and fuel levels (for diesel units). Verify proper airflow, fan operation, and refrigeration system pressures. Check refrigerant levels, temperature sensors, and door seals. Reset the system after fixing minor issues; consult manuals or technicians for persistent or complex problems.
