Refrigerated Containers

Refrigerated containers are designed to store product that requires temperature control. They operate independently of a blown air refrigerated system and are fitted with their own refrigeration units which require an electrical power supply for operation. Called also as reefers, these containers can hold a constant temperature of +27 degrees C to -28 degrees C and are an economical cool storage solution. All reefers are powered by 15 amp or 30 amp 3 phase power only. As the floor is “T” section the air can flow beneath stored product. Internally these containers are lined with either stainless steel or GRP. Each container is capable of being set at its own individual carriage temperature.

What is Refrigerated Freight?

Temperature controlled freight is an enormous division of the shipping industry. Think about how much food is transported daily across the country. We have millions of fast food restaurants, grocery stores, restaurants, hotels, hospitals, and schools which all require food products to arrive refrigerated. Refrigerated trucks made it possible for food that has to travel a great distances in a short amount of time to avoid spoilage.

Hospitals and medical laboratories generally cannot accept shipments of certain medicines, which have not been properly shipped. A degree above or below the specified
temperature can harmfully effect the shipment. This also applies to foods, which have been shipped to restaurants, hotels, hospitals, or other institutional kitchens. New technology is continually being developed to provide greater control of reefer temperatures. Some specialized units even provide a continuous record of the cargo temperatures from loading to unloading.

Many carriers have added refrigerated freight shipping to diversification in their services in order to survive slowdowns or setbacks in other division of shipping. Carriers who take on refrigerated freight must have trust in their drivers because of the increased risk of loss due to mechanical problems. Purchasing a computerized reefers and properly training drivers are excellent safeguards.

Features and benefits of a refrigerated storage container

The following are the features and benefits of a refrigerated storage container:

1. 2000 cubic ft. (56 cubic meters) capacity for 40′ container.
2. 1000 cubic ft. (28 cubic meters) capacity for 20′ container.
3. They run only the units you need based on the volume of product to be cooled.
4. They have portable units.
5. Significant capital cost savings compared to standard walk-in coolers.
6. Tight construction – these units are delivered in one piece and constructed for minimal air leakage and maximum thermal efficiency.

Tips that will help you to keep your storage in needed condition:

1. Proper air circulation both inside and outside the container. It is important to keep clear the interior floor air space (under the “T” surface) and the ceiling air space (above the red load line) to facilitate proper air flow and cooling through out the container. Moreover, the area outside the container must provide for adequate airflow though the condenser, to insure peak performance.
2. The electrical power supply must be reliable and within the design ranges at the supply panel.
3. The doors are only opened for loading and when closed, fully closed.
4. Warm product loaded into the container will cause an increased temperature inside the container, possible spoilage of the product and necessitate increased defrosting of the evaporator coil.
5. The controls are meant to be set and left alone, any adjustment of settings or controls by non-qualified personnel could result in a performance failure.
