How to clean and maintain your water chiller


Both industrial cooling systems and personal air conditioning units rely on water chillers to maintain a cool temperature. Like any other mechanical equipment, water chillers need routine cleaning and maintenance to last longer and perform with ease. Ignoring the proper care might result in insufficient cooling, enhanced energy consumption, and even expensive breakdowns. Here, we will guide you through the steps of water chiller cleaning and maintenance services.

Also, the guide includes handy tips on what to check, when to conduct maintenance, and how to keep everything running smoothly.

Importance of Water Chiller Cleaning and Maintenance

Before diving into the how-to, let’s figure out why water chiller cleaning and maintenance are important. The following reasons provoke the necessity of water-cooled chiller chemical cleaning.

Efficiency Intact

Dust, dirt, and debris can accumulate on your water chiller over time. And the filters, coils, and tubes can get clogged. This affects the chiller’s efficiency. Indeed, the water chiller finds it more difficult to work and may end up consuming more energy.

Boosted Longevity

Just like any piece of machinery, the better you take care of the water chiller, the longer it will last. Indeed, cleaning a chiller periodically and regular maintenance can restrict premature wear and tear. Also, it reduces the likelihood of breakdowns.

Bacteria and Algae Growth Prohibited

Water chillers, particularly those in industries like pharmaceuticals or food processing, need clean, contaminant-free water. The lack of cleaning and maintenance can lead to mould, algae, and bacteria growth in the system. Consequently, the health of your employees and the quality of your products can be compromised.

Repair Costs Minimised

Regular water chiller cleaning and maintenance can help you identify minor issues before they escalate. So, focus on comprehensive chiller cleaning and maintenance if you don’t want to face costlier problems. Save yourself from unexpected repairs and replacements with the proper chiller tube cleaning procedure.

How to Clean a Water Chiller: 10 Steps

1. Shut Down the Water Chiller

Before you begin with anything, always turn off the chiller. This is unskippable for safety before the chiller cleaning procedure. It reduces the risk of electrical shock or accidental operation during maintenance.

2. Refer to the Manufacturer’s Instructions

Every water chiller model might have dedicated maintenance instructions. Hence, it’s crucial to consult the manufacturer’s manual for a water-cooled chiller chemical cleaning. Make sure you stick to any recommended procedures, especially for disassembling or cleaning.

3. Clean the Coils

The condenser coils are one of the most significant parts of the chiller. Over time, they tend to accumulate dirt, dust, and grime. This reduces heat transfer and causes the overall system to work harder.

Here’s what you need to keep in mind while cleaning the coils of the water chiller:

  • Use a soft brush to dust the condenser coil.
  • Also, you can use a vacuum with a soft brush attachment to remove the accumulated dirt and dust from the coil.
  • Be careful and gentle while brushing the coils; otherwise, you might end up damaging the fins.
  • If required, you can purchase a recommended coil cleaner spray and use it for tougher grime.
  • Ensure that you clean both the condenser and evaporator coils.

4. Examine and Clean the Filters

Clogged filters in your water chiller can block the flow. And the efficiency of the equipment can be at stake. On the other hand, the energy consumption can increase multiple times. Here’s what cleaning a water chiller filter takes:

  • Spot the filter with the help of the manufacturer’s user manual. Based on the design of the chiller, you might have to access the control panel or remove the housing.
  • After that, inspect the filter for dirt, debris, or any other visible contaminants. Also, look out for signs of wear and tear if your filter is made up of a washable material.
  • Rinse the filter under running water if it’s washable. Or else, you need to follow the manufacturer-recommended water-cooled chiller chemical cleaning process.
  • Let the filter dry. Then, you can place the filter inside your water chiller.

5. Pay Attention to the Water Flow and Pump

There may be an issue because of a low-performing water pump that affects the flow and circulation of chilled water. Indeed, it can get clogged up with mineral deposits. So you can follow the steps listed below along with a chiller tube cleaning procedure:

  • Check the water pump and inlet/outlet pipes for any clogging.
  • If you notice any form of buildup, clean the pipes with a vinegar solution or descaling agent. However, while picking up a commercial descaling agent, be careful.

6. Check the Refrigerant Levels

Water chillers rely on refrigerant to cool the water. Thus, low refrigerant levels can cause a problem in cooling performance. Now, it is best that you call a professional when refrigerant-related problems appear, but you can look out for leaks on refrigerant lines.

  • Check your water chillers for these visible signs of leakage or ice buildup on the refrigerant lines.
  • If you notice something unusual, then it is recommended to take advice from a chiller repair expert who will check the refrigerant level and add it as required.

7. Drain and Flush the System

You will be able to get rid of all debris that might have accumulated along the pipes and components of the unit if you dismantle and clean your water chiller quite often. To your notice, this process guarantees the smooth circulation of water. In like manner, the working efficiency of your chiller does not alter.

To clean a water chiller, you must follow the guidelines below:

  • Drain the water from the chiller system.
  • Flush the reservoir with fresh water to remove scale or debris.
  • You may add a system cleaner for a better outcome.

However, you should always stick to the manufacturer’s guidelines on flushing and chiller tube cleaning procedures.

8. Lubricate the Moving Parts

If your chiller has moving parts, such as fans or motors, then you would need to lubricate those. And don’t forget, this process itself cuts down friction, enhances efficiency, and prevents early wear.

So, you can use a lubricant recommended by the manufacturer. Then, apply it to the moving parts as instructed. Do not overlubricate the moving parts. This will attract dust, dirt, and grime, and the situation becomes worse.

9. Inspect the Electrical Components

However, you are supposed to check the electrical parts of the water chiller for any wear or damage. For instance, you can look for frayed wires, signs of overheating, and also any malfunctioning sensors.

  • Inspect all electrical connections and control panels for signs of corrosion or damage.
  • However, you can hire a Chiller Repair Dubai technician if you are not comfortable with such checkups.

10. Water Chiller Testing

Now that you have cleaned and maintained the water chiller, you can now turn it on. Then, you have to test the chiller to ensure everything works right. Remember to test its cooling performance, airflow, and all the operations.

Maintenance Checklist for Your Water Chiller

Aside from water chiller cleaning, you may add these regular maintenance activities for optimal functioning of the equipment.

Set Scheduled Inspection

Schedule annual or biannual servicing with a certified and experienced technician.

Check the Performance

Keep a check on the performance of the system as well. If you happen to notice any sudden drop in cooling efficiency or sense some chemical smell or noise, take action on an emergency basis.

Maintain the Water Quality

The water to be used in the chiller system should contain no minerals or dirt. Moreover, you can be provided with a water softener so that scale formation is avoided.

Look for Leakage

Check the coils, pipes, and refrigerant lines for the leakage of the water chiller. If neglected, it contributes to low performance and energy wastage as well.

Conclusion….

Cleaning a water chiller doesn’t mean that you’ve got to mess around. Absolutely, you can maintain that machinery to be in great condition for years with proper maintenance steps. But you can request a professional Chiller Repair Dubai service to ensure complete cleaning and overall maintenance.
