- Check the machine's gaskets and seals: Worn-out or damaged gaskets and seals can cause air leaks, which can lead to increased energy consumption.
Check these components regularly and replace them if necessary. By following these tips, you can reduce your energy consumption, lower your electricity bills, and improve the efficiency of your commercial ice machine
Water Filter For Icemaker
Water filtration systems are crucial components for commercial ice machines. They are designed to remove large particles, scale, rust, cysts, sediment, and mineral deposits that can negatively affect the quality of ice. Investing in a water filtration system can save you thousands of dollars in equipment repairs and replacements in the long run.
When choosing a water filtration system, it's a good idea to consult the manufacturer of your commercial ice machine for advice. However, it's also important to do your own research and compare different products on store shelves.
It's essential to understand that roughing water filters do NOT remove odor or alter the taste of the water - they serve a different purpose. If you want to alter the taste and remove odors, you'll need to invest in activated carbon filters or reverse osmosis systems. Depending on your situation, you may or may NOT need these.
To determine when to replace the water filter, there are three primary methods:
- Visual examination: Simply inspecting the filter and deciding if it needs to be changed. This method is perception-based and the least accurate.
- Time-based: Replacing the filter after a certain amount of time, which may require trial and error to determine. This method is recommended and requires benchmarking, which can be slightly costly.
- Gauge or sensor Based: This is the most cost-effective method, although it can be a logistical nightmare if not automated with some averaging techniques.
A hybrid combination of visual examination and time-based scheduling is recommended for DIY. Keeping track of the system's performance and then creating a preventive maintenance schedule based on that information is the best way to go.
Adding a water filter to your ice machine can help reduce the number of impurities in the water, extending the machine's service life. However, it's important to understand that water filters can only slow down the buildup of gunk over time. Eventually, it will accumulate regardless. Remember to follow the manufacturer's instructions on how to properly install and maintain your water filter to ensure maximum commercial ice machine efficiency and performance.
.
Reverse Osmosis for Icemakers
Reverse osmosis systems can significantly reduce soda lime formation in ice machines, which is a major cause of leaks and poor ice shape. When water velocity is reduced in the drainage section, soda lime formation can occur, leading to clogs in the system over time. Many repair service calls for "ice machine leaking water" are actually caused by soda-lime formation. An example of a soda-lime formation clog on a Hoshizaki ice machine is shown in the picture, which required 2 hours of diagnosis and repair.
Owners of commercial ice machines often do not have a reverse osmosis system installed, or at best, have a neglected inline roughing water filter. However, installing a good quality reverse osmosis system can reduce commercial ice machine repair costs and improve the quality of the ice produced. Purified ice is harder and slower to melt, leading to a better customer experience.
"Lime scale is the enemy of clear ice and optimal machine performance." Manitowoc
Finding a good match for your commercial ice maker can be tricky, as residential reverse osmosis systems are typically not suited for commercial ice makers. Commercial ice machines can use up to 100 gallons of water per day and require about 40 PSI to operate. A residential RO system drops the incoming pressure by 30% roughly speaking, which may cause a problem if the incoming water pressure is 40 PSI. Therefore, it's important to consult with the manufacturer and get expert advice before installing a reverse osmosis system.
Reverse osmosis systems come in many shapes, forms, and different prices. We do not recommend any brand in particular. In summary, reverse osmosis systems are good for commercial ice machines, but the volume (gallons per day) and pressure (PSI) are of critical importance. Consulting with the manufacturer and getting expert advice is recommended before installation.
Sanitizing vs Cleaning your Commercial Ice Machine
While sanitizing and cleaning are often used interchangeably, they are two distinct processes with different goals. Sanitizing reduces the number of harmful bacteria and viruses to a safe level, while cleaning removes visible dirt, debris, and buildup from surfaces. When it comes to commercial ice machines, both cleaning and sanitizing are important to ensure the production of safe, clean ice for consumption.
Cleaning
This step defines a cleaning schedule and the cleaning product as it prevents build-up on the evaporator section of the system. Not all cleaning agents are equal some are very acidic and will react with the evaporator. The evaporator is one of the most expansive and most difficult parts to troubleshoot in a given commercial ice maker it is as difficult and as expansive to replace a freon leak.
We strongly recommend you check the user manual for selecting the proper cleaning solution. Several ice-bed-evaporators are Nickel based material, using the wrong cleaning agent will destroy the smoothness of the ice-formation layer.
Sanitzing
Ice Machine Condenser Coil Cleaning
It's essential to clean the condensing coil of all refrigeration equipment, including commercial ice machines, reach-in coolers, walk-in freezers, pizza prep stations, and sandwich prep, as part of preventive maintenance. The process involves removing dust and debris from the coil to enable good heat exchange and protect the equipment compressor. Food establishments that use fryers are particularly susceptible to condenser coil blockages caused by oil and dust particles. Therefore, we recommend cleaning the condenser coil at least twice a year.
Cleaning the coil involves using a regular soap solution and a condenser cleaning agent by following the next steps:
- Removing the plug from power from the outlet
- Isolating electrical components and electrical wires from water
- Soaking Condensing unit with water
- Applying water with the cleaning solution,
- Rinsing three times with water
- Allowing the system to dry before plugin the unit
There are several condenser cleaning products to choose from, and while we do not recommend any particular brand, we have been using Simple Green.
Dirty vs Clean real-life ice maker condensing coil
To illustrate the importance of condenser coil cleaning, we have included a real-life before-and-after cleaning preventive maintenance picture of the same condenser coil from a commercial ice machine. Even though some claim their ice machine condensing coil is clean, we frequently encounter similarly dirty coils. It's crucial to note that you should be able to see light through the condenser coil, and anything less than that indicates clogging and results in high overhead pressure. Neglecting to clean condenser coils will lead to premature compressor failure, and it could also void your ice machine warranty. Therefore, it's imperative to prioritize condenser coil cleaning as part of your preventive maintenance routine.
Before you buy an ice machine
Typically businesses purchase ice machines based on the "budget" they have. Usually, they end up with non-performing equipment. Here are the priorities for purchasing an ice maker:
- Ice shape and size (Cube / Nugget / Flake)
- Demand how many pounds per hour (some ice makers refill every 2 minutes and others every 10 minutes)
- Available Space
- Brand (unfortunately not all ice maker manufacturers are equal some are sturdy and barely break with a good warranty and others are just a waste of money)
- Cost (notice we are not saying price)
