TR-400E Trailer Refrigeration Unit Introduction

Reefer trailer refrigeration freezer units are a critical component for many businesses that rely on transporting perishable goods.

A reefer trailer refrigeration freezer unit is a crucial piece of equipment for many industries that rely on transporting perishable goods. From food and pharmaceuticals to chemicals and medical supplies, these units play a vital role in ensuring that products remain at the correct temperature during transit.

Benefits of Reefer Trailer Refrigeration Freezer Units

Versatility: Reefer trailer refrigeration freezer units can be used to transport a wide range of products, from frozen foods and ice cream to vaccines and medical supplies.
Temperature control: Reefer trailer refrigeration freezer units provide precise temperature control, which is critical for transporting perishable goods safely. They can maintain the temperature of the cargo within a narrow range, ensuring that it stays fresh and safe for consumption or use.
Reliability: These units are built to withstand the rigors of long-distance transportation and are designed to operate reliably in a variety of weather conditions.

How do Reefer Trailer Freezer Units Work?
Reefer trailer freezer units work by removing heat from the air inside the trailer, which in turn lowers the temperature of the cargo. They achieve this using a refrigeration system that circulates a coolant fluid around a closed loop, absorbing heat from the trailer's air and dissipating it outside.

The coolant fluid typically used in these units is a type of refrigerant that has a low boiling point, such as ammonia, carbon dioxide, or Freon. The refrigerant is compressed, which raises its temperature and pressure, and then passed through a condenser where it releases heat to the environment. After that, it's expanded through a valve, which lowers its pressure and temperature, and then circulated through an evaporator inside the trailer, where it absorbs heat from the air and cools it down.

The process continues in a cycle, with the refrigerant being compressed and expanded repeatedly to maintain the desired temperature inside the trailer. This cycle is controlled by a thermostat that senses the temperature of the air inside the trailer and adjusts the operation of the refrigeration system accordingly.

Best Practices for Reefer Trailer Refrigeration Units
To ensure that your reefer trailer refrigeration unit operates at its best, here are some best practices to follow:

Regular maintenance: Regular maintenance is critical to ensure that your unit operates efficiently and reliably. This includes cleaning the condenser and evaporator coils, checking the refrigerant levels, and inspecting the unit's components for wear and tear.

Proper loading: Proper loading of the trailer is essential to ensure that the cold air circulates evenly throughout the cargo. Avoid overloading the trailer or packing it too tightly, as this can hinder airflow and lead to uneven cooling.

Temperature monitoring: Use a data logger or a remote monitoring system to track the temperature inside the trailer during transit. This can help you identify any temperature fluctuations and take corrective action if necessary.

Fuel management: Fuel management is essential to ensure that the unit operates efficiently and maximizes fuel economy. Plan your route carefully and avoid unnecessary idling or speeding, as these can increase fuel consumption and reduce the unit's lifespan.
