The world would not be familiar to us without the use of refrigeration and the various types of refrigeration services available today. While many people were involved in the early stages of inventing refrigeration, it was Alexander Twining to be the first credited for the development. Widely accepted by the railroad industry, it was actually the beer breweries to lead the demand for a way to chill their products. Truly, necessity is the mother of invention.

There are several different types of commercial refrigeration. If you own a restaurant or grocery store, you are probably using several of them now.

The Blast Chillers

Blast chilling refers to a method of taking prepared food and quickly cooling it before bacteria as a chance to multiply. Restaurants find this type of commercial refrigeration

highly useful because large quantities of food can be cooked and then quickly stored for later use. The benefit is lower cost per serving and higher profit margins because there is less spoilage. The catering industry also uses blast chilling as a method of preparing and storing food before a large event.

The Walk in Freezer

Cleanliness and utilization of space is important in the restaurant business. That is why they rely on stainless steel commercial refrigeration units known as walk-in freezers. These big freezers allow them to buy large quantities of frozen foods and meat at wholesale prices. The typical Walk in Freezer will have temperatures below 0 degrees insuring the safe storage and processing food.

The Display Freezer

The display freezer is another of the commercial refrigeration units and that is essential when owning a grocery store. These units come in a wide variety of shapes and styles test and are used to sell everything from TV dinners to ice cream. They are highly functional and come with the adjustable shelves making them perfect for displaying a variety of frozen products.

The manufacturers of refrigeration units are going green today. This means the cost to operate these large refrigeration units are going down. New technologies and design features allow large freezers to be expandable by adding interlocking walls. These modular designs are saving space while saving money. However, as with everything else, there will be maintenance needs. There are many professional refrigeration services available to you when your refrigeration units need servicing. It is best to interview one before you need them. This way you will have their number in hand in case of an emergency.

When looking for qualified refrigeration services it is a good idea to check their references. Talk to them and find out how pleased they are with the service. Ask about their promptness and quality of work. What kind of parts did they use and did the parts come with a good warranty? Be sure to check their insurance. Make sure they carry minimum levels of liability insurance as well as worker's compensation insurance. This is to protect you from liability should someone get hurt. It will also protect you from any loss suffered because of their workmanship. Ask them about their rates and service plans. It may be cheaper to purchase a service plan from them and then pay a flat monthly fee. Should an emergency or breakdown happen, all you have to do is call your refrigeration services company.
