What Causes Commercial Refrigeration Leaks

There are many reasons why your commercial refrigeration system may be leaking. It could have been improperly installed, or handled poorly during service or maintenance. Some reasons why include:

  • Compressor discharge lines vibrations

Lines or fittings may break due vibrations, with most of a system’s vibrations being on or around the compressor discharge lines.

  • Corrosion

Exposure to certain liquids or condensation may cause corrosion. Copper exposed to anything acidic (including foods that are acidic) will corrode – an evaporator made of copper will develop pinhole leaks. Condensation forming can cause leakage to certain components such as a compressor rack. Cleaning the system with the wrong kind of cleaning material can cause corrosion. It’s very important that the correct cleaning material is used, as not every kind is compatible with every refrigeration system. Make sure technicians cleaning your system use the correct kind.

  • Fittings not tightened well

Threaded or flared fittings can cause leaks if they are under tightened or over-tightened to the point cracks form.

  • Improper Brazing

The brazing alloy used may be the incorrect kind, the metal before the brazing may not have been cleaned properly or the brazing technique was simply faulty, such as the temperature not being distributed well and the metal not melting as it should.

  • Metal contact with tubing

Copper tubing can come in contact with other tubing, or other harder metals such as steel and can rub through the tubing walls.

  • Missing valve caps/seals

Valve stems must have valve caps as well as seal/o-rings to prevent leaking.

  • Retrofitting or different kind of oil or refrigerant used

The parts of a system respond differently to different kinds of refrigerant or oils. If the system is being retrofitted with a new refrigerant or oil, some parts may swell differently than before and will need to be replaced.

  • Stress on tubing

Copper tubing that is not correctly supported will sag, like at 90 degree turns, and cause stress which can lead to lines or fittings to break.

  • Thermal stress

Expansion and contraction of the piping is normal, as the temperature in a refrigeration system is always changing. However, if there is not suitable room for it to expand the fittings supporting the pipe may break. Further more, constant expanding and contraction can affect the sealing of gaskets and seals.

An electronic leak detector may help with determining whether there is a leak or not. Make sure it can detect the same kind of refrigerant your system uses, as there are different types on the market, some that can detect some kinds of refrigerant better than others.

If you think your commercial refrigeration system has a leak, or would like to sign up for our preventative maintenance program please give us a call or contact us today. B & G Refrigeration is licensed by the State of Florida and all of our technicians are qualified to install  and work on your refrigeration system.

Have a great day!

Why Might a Compressor Fail

A few reasons why a compressor might fail:

  • Electrical problems – which is a major cause of compressor failure – including: faulty wiring done by the technician improperly wiring the compressor, low voltage, a bad or incorrectly-sized capacitor, compressor short-cycling or motor overload.
  • Liquid flooding is liquid returning to the compressor while it is still running. Liquid droplets dilute the oil, which prevents the parts of the compressor from being properly lubricated, which in turn leads to wear of parts and overheating. Slugging is the return of a mass of liquid, usually refrigerant and/oil. Compressors cannot compress liquids and will lead to a broken compentant usually if slugging occurs. To prevent liquid flooding/flooback and slugging, an accumulator can used. It will act as a reservoir, keeping liquid from entering the compressor.
  • Lack of oil, which as mention can be caused from liquid floodback, results in wear of the compressor, which will cause overheating and the compressor to seize up. Some reasons why the compressor isn’t properly oiled include: the gas velocity being too small to pick up the oil, a lack of refrigerant in the system, an oversized suction line, short-cycling or a blockage in the system.
  • Improper control settings can lead to the overheating of the system.
  • The only things allowed inside a refrigeration system is oil and refrigerant. Anything besides these is considered a contaminant, including air, scale, moisture or any kind of dirt. Contaminants can lead to system failure, so make sure that the system is clean and there is nothing besides oil and refrigerant in there, and even then, make sure those are at proper levels and not going into the wrong place.

Ice Machine Maintenance

Not only will B&G Refrigeration install or repair ice machines for your business, we also perform preventative maintenance.

If you already own an ice machine for your business, it’s highly recommended that a deep cleaning is done once a year as well as quarterly or biannual preventative maintenance. To help your ice machine produce clean ice, and increase the machine’s lifespan, it’s also highly recommended that filtration is installed.

Give us a call if you’d like to keep your business’ ice machine in tip-top shape! We hope you’re having a wonderful Spring!

Designing your first kitchen

One of the most important things in developing your commercial eatery is designing your commercial kitchen. There are so many factors that go into utilizing the right amount of space and laying out the right equipment to start and leaving enough room to expand. It’s almost like putting together a maze. It doesn’t have to be. At B&G Refrigeration, we’ve had the pleasure of working with hundreds of different kitchens and we wanted to offer our best advice for designing a commercial kitchen.

Things to consider for an ideal commercial kitchen design:

Space limits
There are undoubtedly limitations you’ll come across in the architecture and design of the kitchen area.

When creating the design of your kitchen, it’s important to consider safety first. You’ll need to ensure that your kitchen is well lit, ensure there’s enough room to move freely and that there’s consideration for mobilizing hot foot and transporting sharp objects.

It’s important to ensure that the layout of your kitchen is optimal for maximum efficiency. For instance, does the layout force your workers to waste time walking back and forth to prepare the food and clean whereas it should only take a few steps.
