Buying a refrigerator

By reklicom

Second hand refrigeration equipment is often thought to be good value for money for the small to medium catering or leisure business. Unfortunately, as many will testify, this is a false economy.

Today, modern refrigerators count with more than one compartment, the two basic areas are the fridge which keeps the food at a temperature which is a few degrees above the temperature at which water becomes a solid or frozen and the other compartment which keeps food at temperature below water's freezing point.

Although it does so much for the household and most dependable of all large appliances, they do fail to do their jobs sometimes, and when they do, the results can be disastrous because expensive food can spoil in a hurry. There are a few simple repairs you can handle yourself by checking the power, controls, condenser coils, and other parts outside of your refrigerator's sealed, hermetic system. Remember that the best way to lengthen the life of a refrigerator is to clean the condenser coils once a year or more frequently if they get dirty.

This will help to keep the door of the refrigerator closed during the heat of the day. Also, make sure your refrigerator isn't so crammed full of stuff that it can't "breathe". Refrigerators need good air circulation to work efficiently.

You can also install a fan in the rear part of the refrigerator to help the air flow through the condenser fins at the top of the cooling unit. Slip a piece of paper between the door and the refrigerator cabinet; then close the door. If you don't feel a slight resistance when you pull the paper out from the door, then the seal is leaking. Replace the seal as soon as possible.

Commercial refrigeration depends on reliability and quality, and even the best second hand equipment can't offer that with certainty. The only way to personally ensure your business is covered is to invest in new refrigeration equipment.

As time went by, ammonia was replaced with a safer refrigerant called Freon or R-12, ever since this new substance started to be used to make refrigerators work this machine became highly commercial since it was now safe and convenient to use.

Additionally, you can generally get a fair idea of the state of the vehicle simply by looking at it, which means you can weigh up your decision effectively, even without a trained eye. Add to that a record of past ownership and an indication of level of use through mileage and you're going to be capable of forming a rounded opinion.

As you can see, the refrigerator is a critical appliance which has to be working at all times, otherwise our foods get spoiled, but what happens when something goes wrong with it, do you panic and buy a new one or do you try to fix the problem?

Try tipping the refrigerator upside down to dislodge the particles. You may replace the cooling unit, or replace the whole refrigerator. However, for a rather complex problem, like rebuilding of the ammonia cooling units that power the fridge, you need to have an expert's eye on it to get the details just right. - 15246
