Refrigerated trailers play a vital role in the food transportation industry

 

Refrigerated trailers

by ensuring safe and hygienic delivery of perishable goods over long distances. With growing demand for chilled and frozen food items, refrigerated trailers have become an indispensable part of the cold chain logistics.

 

Types of Refrigerated Trailers

There are different types of refrigerated trailers developed for specific temperature controlled transportation needs:

Frozen Food Trailers

Frozen food trailers maintain temperatures below 0°F to transport items like meat, seafood, ice cream etc. which require frozen temperatures. They have insulated walls and roofs along with heavy-duty refrigeration units to keep contents frozen during transit.

Chilled Food Trailers

Chilled food trailers are designed to carry food and beverages requiring temperatures between 35°F to 45°F. Products like dairy, fruits, vegetables and juices are transported using chilled trailers. They have powerful yet energy efficient refrigeration systems.

Pharmaceutical Trailers

For transport of temperature sensitive pharmaceutical drugs and medical supplies, pharmaceutical trailers precisely maintain temperatures between 45°F to 80°F. They have calibrated sensors, alarms and data loggers for compliance with regulatory standards.

Beverage Trailers

Non-alcoholic and alcoholic beverage trailers are optimized for transport of drinks in cartons or bottles/cans. They ensure contents remain at temperatures acceptable for consumption without compromising taste and quality.

Key Features of Refrigerated Trailers

Insulation

Trailer bodies are heavily insulated using high-density foams or vacuum insulation panels to restrict heat transfer through walls and doors. Effective insulation helps refrigeration units maintain set temperatures efficiently.

Refrigeration Units

Reliable and durable refrigeration units powered by diesel fuels are installed in trailers. Advanced units provide temperature controlled air circulation ensuring uniform cooling. Backup generators ensure uninterrupted cooling during power outages.

Temperature Monitoring

Refrigerated trailers have electronic temperature display/control panel and logging systems to closely monitor and record internal temperatures throughout transit. Any temperature excursions instantly trigger visual/audio alarms.

Alarm Systems

To avoid product spoilage, refrigerated trailers have thermostats connected to audible and visible alarm systems. Alarms instantly notify drivers in case of equipment malfunctions or temperature excursions beyond set limits.

Tracking and Monitoring Technologies

Fleet management systems and GPS trackers help remotely monitor refrigerated trailers. Built-in sensors transmit temperature and location data in real-time for proactive interventions if needed. This ensures on-time deliveries of goods in ideal conditions.

Considerations for Refrigerated Trailer Purchase

Cargo Space and Doors

The size, number and type of doors depends on cargo dimensions and ease of loading/unloading. Reach-in or walk-in frames suit different application needs. Insulated floors withstand temperature variations.

Fuel Efficiency

Look for trailers with aerodynamic designs, lightweight construction and EPA-certified fuel-efficient refrigeration units to reduce operational costs. Hybrid electric units improve efficiency.

Reliability and Durability

Heavy-duty chassis, wheels, suspension systems and corrosion resistant components ensure longevity. Backup systems provide uninterrupted refrigeration during frequent use over many years.

Temperature Range

Consider application temperatures while choosing trailers certified for frozen, chilled or pharmaceutical ranges. Precise controls are critical for temperature sensitive cargo.

Maintenance and Service

Ease of cleaning, serviceability, spare part availability and warranty support determine long term cost of ownership. Dealers with nationwide servicing network offer added advantage.

Regulatory Compliance

Refrigerated trailers must meet safety, emissions and food safety standards. Certifications provide legal compliance assurance for domestic and international freight transportation.

From frozen meat to fresh produce, refrigerated trailers have revolutionized long haul transportation of perishable goods. Advanced technologies now enable real-time monitoring and control over cargo temperatures nationwide. With continually improving cold chain infrastructure, refrigerated trailers will facilitate further growth of temperature controlled supply chains globally. Purchasing the right type of refrigerated trailer suited for the application ensures sustainable and compliant food transportation.
