Maintaining Your Commercial Refrigeration
Maintenance of refrigeration needs to be at the forefront of every good Catering and Hospitality business. Why you say?
Well, consider your car for a moment. It could be worth about the same as your combined refrigeration equipment. It gets used for approximately 2 hours a day and is serviced on schedule every few months. We look after our cars because they are an investment.
Commercial Refrigeration Equipment
Your commercial refrigeration equipment is the hardest working piece of equipment in your business. When you lock up and go home, your fridge plant keeps running 24 hours a day, 7 days a week. Its no wonder they tend to break down at the worst inconvenient time you can imagine.
And yet we commonly see that in the majority of cases, a refrigeration breakdown could have been prevented with a good maintenance regime. The image above shows the back side of an evaporator in a cool room. We took this photo halfway through cleaning it. Seriously, if this was in your fridge at home it wouldn’t be good enough. We are constantly amazed that business owners risk health issues to this level by ignoring maintenance.
This condensing unit located on the client’s roof needed an urgent compressor change. I think it is fair to say that judging by the number of pigeon feces this expensive failure could have been prevented with occasional maintenance!
Hats off to my tradesman who persevered with the disgusting job in order to get it back online so fast. Of course, once up and going the system was rinsed down.
The underlying message is that when your refrigeration equipment is located out of sight you have no idea what condition it is in. Therefore, maintenance is so important if you want to have reliable commercial fridge plant.
What is done during commercial refrigeration maintenance?
When servicing a fridge, we look at the key indicators for good performance;
|Door gaskets||Drain operation|
|Gas charge||Moisture indication (refrigerant)|
|Clean condensers||Clean evaporators|
|Condenser fans running smoothly||Evaporator fans running smoothly|
|Condenser air circulation||Environmental conditions and influence|
|Temperature control management||Defrost operational|
|Door hinges||Door strikes and latches|
The importance of ice machine maintenance
When servicing an Ice Machine, it is important to realise that at the completion of our works, that all ice will be fit for human consumption. Whilst some commercial catering clients over look this health consideration, I often ask; – “Would you leave water in a glass for 2 months and then give it to someone to drink?” Obviously, the answer is a resounding “NO”, so the next question I have is why then, do people leave ice machines without any attention until they breakdown? You wouldn’t believe the gunk we find in the ice bins sometimes!
Ice is a food
The capital outlay of purchasing a new ice machine far outweighs the cost of maintaining one. Whilst we accept that the cost of maintenance is not attractive to many clients, the benefit of having ice readily available for commercial catering equipment users is seen as paramount to running a good food and beverage service. No one wants to run down to the service station for more ice at 10pm during peak hour at the bar!
The trick with ice machines is to keep them clean. The ice production process actually only turns the best parts of the water into ice. Leaving scale and dissolved solids to clog up the rest of the ice machine. When these deposit onto the evaporator coil it can bind the ice to the coil and the result is bad ice formation and eventually the problem causes a myriad of other issues that will lead to the need for a major overhaul or replacement of the machine. With a good maintenance regime, you can get many more years of life out of your ice machine.
