30KAV Maintenance:
With its advanced components and cutting-edge features, maintaining the 30KAV is essential to ensure optimal performance. Proper maintenance saves energy, reduces downtime, and extends the life of the chiller. Neglecting maintenance leads to increased operational costs and unplanned outages. To maximize the benefits of this innovation, it’s crucial to establish a robust maintenance program.
At Mandilas, we’ve identified key preventive maintenance practices that can ensure the 30KAV runs efficiently and reliably.
Daily Chiller Log:
Maintaining a daily log of the chiller’s operating conditions is the foundation of an effective maintenance program. This log captures essential data such as temperatures, pressures, and alarm histories, helping technicians identify potential issues before they escalate. Monitoring daily trends allows for timely preventive maintenance, reducing the risk of costly unplanned outages.
Condenser Coils and Evaporator Tubes:
The performance of the 30KAV heavily relies on clean condenser coils and evaporator tubes. Contaminants like scale, mud, algae, and other impurities reduce heat transfer efficiency, increasing thermal resistance. Monitoring the temperature differential (delta T) between entering and leaving water temperatures is crucial. A rising delta T signals reduced efficiency and potential performance issues. Regular cleaning of condenser coils (quarterly) and evaporator tubes (annually) prevent fouling and maintains optimal performance.
Refrigerant Charge:
Proper refrigerant levels are critical to the chiller’s cooling capacity. Maintaining the correct charge ensures that the compressor doesn’t overwork. Refrigerant leaks and moisture infiltration reduce efficiency and can lead to system failures. Keeping the refrigerant levels in check prevents unnecessary strain on the compressor.
Compressor Oil Analysis:
Annual oil sampling and analysis provide valuable insights into the condition of the compressor. High moisture levels in the oil or deviations from OEM specifications can indicate underlying issues. Regular oil analysis helps ensure the compressor operates at peak efficiency, and oil filters should be replaced when pressure drops exceed recommended levels.
Variable Speed Drive (VSD) Starters and Compressors:
Efficient operation of VSD starters and compressors relies on the proper calibration of safety sensors and control systems. Annual checks should include thermal scans of electrical connections for hot spots and insulation tests on compressor windings. These preventive measures reduce mechanical stress and extend the chiller’s operational life.
The chiller has heat
recovery and high-performance EC motors options, designed to meet all the requirements.
The 30KAV chiller is designed for use in the following applications: multi-residential,
green buildings, Industries, Data centers, hotels, hospitals.
