Low Flow Alarm

Low flow alarms, an optional addition for some units in the ATC range, serve as a critical warning system in process cooling equipment. These alarms alert operators or maintenance personnel when the flow rate of heat transfer fluid drops below a pre-set level, a crucial safeguard for preventing equipment damage. Process cooling equipment, often used in commercial and industrial settings like data centres or manufacturing processes, relies on consistent fluid flow to remove heat efficiently. If the fluid flow diminishes significantly, it can lead to equipment overheating, potentially causing damage or even complete system shutdown. The inclusion of low flow alarms in chillers is a proactive measure to detect and address flow issues early, enabling prompt corrective action to mitigate risks.

The incorporation of a low flow alarm in a chiller offers numerous advantages. It provides an early warning sign of potential issues, allowing for timely intervention before any significant damage occurs. This feature is essential for maintaining the chiller’s operational efficiency, potentially leading to energy savings, and reduced operational costs. Moreover, it enhanced the overall reliability of the system by ensuring a consistent flow rate thereby lowering the likelihood of maintenance issues and extending the lifespan of both the chiller and connected equipment. In addition, these alarms can significantly reduce unplanned downtime and production interruptions, ensuring smoother operation. They also enhance safety by preventing overheating and the associated risks to personnel working near the equipment.

Despite these benefits, certain considerations accompany the use of low flow alarms. The installation and maintenance of these systems can entail significant costs, particularly for larger, more complex setups. The added complexity of integrating low flow alarms with other monitoring systems may require specialised expertise for setup and operation. In some instances, these alarms may trigger system shutdowns to prevent damage, which, while protective, can lead to unplanned downtime and affect productivity. Additionally, in certain chiller systems where consistent high flow rates are maintained or built-in flow pressure meters are present, the utility of low flow alarms might be limited. Thus, while low flow alarms provide substantial benefits in many scenarios, their necessity and cost-effectiveness should be evaluated based on each system’s specific requirements and operational context.
