Spring and Summer Maintenance Guide for TEYU Water Chillers

As temperatures rise and spring transitions into summer, industrial environments become more challenging for cooling systems. At TEYU S&A, we recommend targeted seasonal maintenance to ensure your 

 

1. Maintain Adequate Clearance for Efficient Heat Dissipation

Proper clearance around the chiller is critical to maintaining effective airflow and preventing heat buildup. The requirements vary based on the industrial chiller’s power:

❆ Low-power chiller models: Ensure at least 1.5 meters of clearance above the top air outlet and 1 meter around the side air inlets.

❆ High-power chiller models: Provide at least 3.5 meters of clearance above and 1 meter at the sides to prevent hot air recirculation and performance degradation.

Always install the unit on a level surface with no obstruction to airflow. Avoid tight corners or confined spaces that restrict ventilation.

2. Avoid Installing in Harsh Environments

Avoid Chillers should be kept away from areas with the following risks:

❆ Corrosive or flammable gases

❆ Heavy dust, oil mist, or conductive particles

❆ High humidity or extreme temperatures

❆ Strong magnetic fields

❆ Direct exposure to sunlight

These factors may severely affect performance or shorten the equipment's lifespan. Choose a stable environment that meets the chiller's ambient temperature and humidity requirements.

3. Smart Placement: What to Do & What to Avoid

❆ Do place the chiller:

     On flat, stable ground

     In well-ventilated areas with sufficient space around all sides

❆ Don't:

     Suspend the chiller without support

     Place it near heat-generating equipment

     Install in unventilated attics, narrow rooms, or under direct sunlight

Proper positioning reduces thermal load, enhances cooling performance, and supports long-term reliability.

3. Keep Air Filters & Condensers Clean

Spring often brings increased airborne particles such as dust and plant fibers. These can accumulate on filters and condenser fins, obstructing airflow and reducing cooling efficiency.

Clean Daily in Dusty Conditions: We recommend daily cleaning of the air filter and condenser during dusty seasons.

⚠ Use Caution: When cleaning with an air gun, keep the nozzle about 15 cm from the fins and blow perpendicularly to avoid damage.

Routine cleaning helps prevent over-temperature alarms and unplanned downtime, ensuring stable cooling throughout the season.

Why Spring & Summer Maintenance Matters

A well-maintained TEYU water chiller not only ensures consistent cooling but also helps prevent unnecessary wear and energy loss. With smart placement, dust control, and environmental awareness, your equipment stays in optimal condition, supporting continuous productivity and extending service life.

 

Spring & Summer Reminder:

During spring and summer maintenance, prioritize tasks such as ensuring adequate ventilation, regularly cleaning air filters and condenser fins, monitoring ambient temperature, and checking water quality. These proactive steps help maintain stable chiller performance under warmer conditions.

How to Maintain An Water Chiller in Winter?

Winter chiller operation requires antifreeze measures to ensure stability. Following these guidelines can help you prevent freezing and safeguard your 

When the Temperature Is Below 0℃, Add Antifreeze: Antifreeze can lower the freezing point of the circulating water, preventing freezing and cracking of pipes and ensuring the sealing of the pipes. Therefore, when the temperature is below 0℃, promptly add antifreeze.

Antifreeze Mixing Ratio: To ensure the normal operation of the laser chiller, strictly control the ratio of antifreeze to water. The recommended ratio is 3:7.

*Tip: It is advised not to exceed 30% for the added antifreeze ratio to prevent pipe blockage and accessories corrosion due to high concentration.

Water Chiller Running 24 Hours: Keep the laser chiller continuously running 24 hours when the ambient temperature is below -15℃ to ensure continuous water circulation and prevent freezing.

Regular Inspections: Periodically check the chiller's cooling system, including cooling water pipes and valves, for any leaks or blockages. Address issues promptly to ensure normal operation.

What Should You Keep In Mind When Not Using The Chiller In Winter?

1. Drainage: Before long-term shutdown, drain the chiller to prevent freezing. Open the bottom drainage valve to let out all the cooling water. Remove the water pipes and internally drain by opening the water fill port and the valve. Then use a compressed air gun to thoroughly dry the internal pipes. 

Note: Avoid blowing air at the joints where yellow labels are pasted above or on the side of the water inlet and outlet, as it may cause damage.

2. Storage: After draining and drying, reseal the chiller. It's recommended to temporarily store the equipment in a place that doesn't affect production. For water chillers exposed to the outdoors, consider measures such as wrapping the chiller with insulating materials to minimize temperature reduction and prevent dust and airborne moisture from entering the cooler.

During winter chiller maintenance, focus on antifreeze fluid, regular inspections, and proper storage. For further assistance, feel free to consult our customer service team via service@teyuchiller.com. For more about TEYU S&A water chiller maintenance, please click TEYU Chiller Case.
