Components of a Reefer Unit

If you’re interested in purchasing a reefer truck, you should familiarize yourself with the different components to make sure you have a quality piece of equipment that keeps food, beverages and other refrigerated items at the optimal temperature.

Understanding What A Reefer Unit Is

At a very basic level, a reefer unit is a refrigerated compartment that uses sophisticated temperature regulation technology to keep goods at the right temperature. It’s a good idea to imagine a very large refrigerator that is designed to keep many types of goods in excellent condition. Here are just a few examples of products a reefer unit helps keep fresh and protected:

  • Meat
  • Seafood
  • Fruit
  • Dairy
  • Pharmaceuticals
  • Flowers
  • Cosmetics

A reefer unit is also versatile. It can be transported across the ocean or hitched to the back of a truck for delivery right to your door.

Components of a Reefer Unit

For a reefer unit to work properly, there need to be a number of components working together to keep items at the optimal temperature. Some of the most essential components include the following:

Refrigeration Unit

The refrigeration unit is the motor of the reefer unit. It helps deliver the cool air needed to keep products at the desired temperature. Usually, a truck’s diesel engine serves as this component’s source of power.

Ventilation and Air Delivery System

It’s also important that a refrigerated unit has the proper ventilation. Often the ventilation system helps release excess heat while an air delivery system ensure proper airflow across the products you’re storing in the unit.

Deep Channel Floors

Also referred to as T-shaped decking, this is a type of flooring built into the bottom of the reefer unit. It’s designed to work with the air delivery system to circulate chilled air through the channels. This process helps keep products at the right temperature and allow for a consistent air exchange between goods

Insulation

The type of insulation used in a reefer truck can vary widely. However, the better the insulation rating, the more energy-efficient the truck will be. Insulation values are expressed through a Ua value. Look for a lower Ua value for increased energy-efficiency, but also realize that lower numbers often mean thicker insulation, which can lead to less available shipping volume available inside a reefer unit.

Reefer Door

The reefer unit door can be a problematic area if it doesn’t feature optimal insulation and a modular design to easily replace damaged parts.

Segmented Design

It’s important that the reefer truck features some kind of seal on the sides and floor to prevent water damage in the event of a leak.

Ultimately, Zanotti provides highly energy-efficient refrigeration units, a vital component necessary to maintain the perfect climate-controlled environment to keep products protected time after time. By delivering high-quality refrigeration units that serve as the heart of any reefer unit, Zanotti helps keep the logistics and transportation industry running.
