10 Things to Consider When Buying 30P refrigerating machine services

5 Signs That You Need Commercial Refrigeration Repair

You can find more information on our web, so please take a look.

You can&#;t afford downtime because commercial refrigerators are essential appliances, especially at convenience stores, restaurants, and liquor stores. Businesses depend on the efficiency of a quality refrigerator. Usually, a quality commercial refrigerator doesn&#;t give you a tough time with regular maintenance since it has an extensive lifespan.

However, there are times when your commercial refrigerator ultimately gives out. Moreover, large businesses operating on commercial refrigerators encounter severe losses if their commercial refrigerators malfunction. This issue is your cue to replace your old commercial refrigerator with a new one.

When your commercial refrigerator wears out, some signs indicate that you need a new industrial freezer installation. We explore the signs below.

1)

Excessive Condensation or Frost

All efficient commercial refrigerators work efficiently to maintain an excellent balance between the hot and cold atmosphere of the fridge. But if you begin noticing excessive frost or condensation inside your refrigerator, your refrigerator is not functioning well and cooling properly. To observe condensation in your refrigerator, examine its rubber sealing.

In case of malfunctioning, you are likely to see condensation, mold, or mildew on the rubber sealing on your refrigerator door. In case of mild condensation on the rubber sealing, you may replace the worn-out rubber sealing on your own, and the fridge is good to go.

However, if there is excessive condensation inside the refrigerator, it may be due to poor temperature settings and maintenance. Again, you may try adjusting the temperature on your own. However, if the temperature issues continue aggravating, it may spoil food and liquors stored inside your fridge.

The risks of business loss may multiply with even a single day of your commercial refrigerator malfunctioning. Take extra care to look for excessive condensation and frost in your freezer maintenance checklist.

2)

Severe Motor Defects

Another significant sign that you need to replace your commercial refrigerator quickly is motor breakdowns. Most refrigerator issues begin with motor failures. When you place your hand at the back of your refrigerator, it is a common experience that you might feel a regular warm temperature change. However, if your refrigerator is transmitting excessive amounts of heat, it is apparent that something is wrong with your refrigerator.

Overheating in refrigerators occurs due to dirty coils. The coils fixed at the back of your refrigerator are insulated. Hence, it must store the heat. In this case, there is a defect in your fridge. As part of your freezer maintenance checklist, you can clean coils by brushing or vacuuming them.

In addition, other motor issues include the refrigerator motor continuously running at maximum speed and making a loud noise. This type of motor defect occurs due to a failing temperature control board. The constant energy transmission to the fan motors and compressor also turns the refrigerator too cold and releases extra energy, leading to an outrageous energy bill. Turn to a technician for help, but if the motor noise continues, invest in a new refrigerator to prevent a costly breakdown.

3)

Excessive Food Expiration

Food spoilage and expiry are signs for commercial owners that their refrigerators are about to fail. Sometimes, the food takes longer to cool or expires faster than the expected expiry date. To ensure that your refrigerator works well, immediately examine the gasket on the door. Dirty or worn-out gaskets do not trap cool air and keep the warm air outside as they should.

You may consider replacing your gasket, which is feasible and inexpensive. However, if the issue persists and your food still takes longer to cool, it cannot regulate the required temperature. It uses unnecessary energy, leading to an excessive need for emergency freezer service.

In that case, you&#;ll lose more money on higher HVAC energy bills and pay for the food spoilage. Hence, investing this money in a new and efficient commercial refrigerator for your business would be better.

4)

Your Temperature Settings Are Not Responding

Your commercial refrigerator operates at zero degrees according to the ideal temperature setting. However, if the temperature feels colder or you begin observing ice formation on every object in the refrigerator, it may lead to severe issues.

One of the first freezer maintenance tips in this situation is to defrost it and examine its functioning. If the problem persists, it might be time to invest in a new industrial freezer installation.

5)

High Electricity Bills

Last but not least, if you get an unusually high energy bill even after using the appliance for the same period, it may be due to your refrigerator defect. Hire a technician to inspect and fix the issue. However, investing in a new refrigerator would be better than consecutive repairs and higher energy bills.

You may also consider calling a repair technician to inspect and remedy the coils and the motor. Replacing the coils could be an option in case of mild malfunctioning.

When buying refrigeration units for walk-in coolers & freezers, it&#;s very important that your refrigeration is sized correctly for your box and application. Incorrectly sized refrigeration can result in problems such as the refrigeration unit constantly running and eventually freezing up.

To help you get the right size refrigeration unit, Heatcraft Worldwide Refrigeration has put together a Quick BTUH Load Calculation Chart. It can be used for walk-ins rooms from 6&#; X 6&#; X 8&#; to 40&#; X 40&#; X 8&#; and with holding temperatures of -20°F, -10°, 0°, 30° and 35°. Loads are calculated based on boxes utilizing 4&#; of urethane R-25 insulation.

Before using these charts, get this information about your walk-in cooler or walk-in freezer:

1. Room information:

&#;Length, width, and height of the box in feet

Goto Kehong to know more.

&#;Holding temperature of the refrigerated room (°F)

&#;Relative humidity in the refrigerated room (if specified)

&#;Summertime design ambient temperature (°F). This is usually the temperature expected at the location of an air cooled condensing unit which cools the room

2. Insulation information:

&#;Type of insulation, insulation thickness (inches), and external temperatures on walls, ceiling, and floor.

3. Infiltration load information:

&#;The temperature (°F) of the entering air and the relative humidity of the entering air. Also, an estimate of the door usage &#; average, heavy, etc.

&#;Does the box have glass doors? Dock doors? How many?

4. Product load information:

&#;What is the product or mix of products being stored?

&#;How many pounds of product entering at what temperature?

&#;How long (hours) does it take to load the product into room?

&#;How quickly (hours) should the room pull the product down to what temperature?

&#;How many pounds of fruit and vegetables are in the room? (respiration load)

5. Miscellaneous loads information:

&#;How many people work in the room?

&#;What is the lighting (watts)?

&#;How many motors (HP) do work in the room?

Here are some ballpark BTUH requirements for common sizes and holding temperatures. Use the &#;Heavy Load&#; calculation for walk-ins with glass doors or ones that have frequent traffic.

Coolers:

35 Degree Cooler with 8ft Height

Freezers:

0 Degree Freezer with 8ft Height

-10 Degree Freezer with 8ft Height
