Freezer vehicles

A freezer vehicle (also known as a refrigerated truck or reefer truck) is a vehicle equipped with a refrigeration unit, designed to transport temperature-sensitive goods, such as food, pharmaceuticals, and other perishable items, at a controlled temperature. Here are the key details about freezer vehicles:

Key Features of Freezer Vehicles:

Refrigeration Unit:

The refrigeration unit is powered either by the vehicle’s engine or an independent power source (such as a diesel engine or electric compressor).
It maintains a constant low temperature inside the cargo area to preserve the contents.

Insulated Body:

The truck body is designed with thermal insulation to prevent external temperatures from affecting the interior temperature.
Insulation material often includes polyurethane foam, which offers excellent thermal resistance.

Temperature Control:

Freezer vehicles typically allow for precise temperature regulation (from sub-zero temperatures for frozen goods to chilled temperatures for fresh produce).
Temperature can be monitored and adjusted from inside the vehicle or remotely.

Cargo Space:

The size of the cargo area can vary depending on the type of vehicle, from small vans to large trucks.
The interior is designed for easy loading and unloading of goods, often with adjustable shelving or pallet spaces.

Doors & Seals:

Freezer vehicles usually have refrigerated doors with tight seals to prevent cold air from escaping and warm air from entering.
Double or insulated doors are common for efficiency.

Power Supply:

Some vehicles use a separate engine (commonly diesel-powered) for refrigeration, allowing the truck engine to focus on driving.
Electric-powered units are also popular, especially for urban areas where emissions are a concern.

Safety Features:

Temperature monitoring systems are commonly installed to ensure that the goods remain within the correct temperature range.
Backup systems can be used to prevent the refrigeration unit from failing and compromising the goods.
