Cooling towers are a major component in a commercial, industrial and institutional facility and comfort cooling systems. They often account for the maximum energy consumption in any HVAC system. A poorly maintained cooling tower reduces chiller efficiency, increases energy consumption and maintenance cost and ultimately leads to system failures.

The building sector, one of the fastest-growing sectors in India alone accounts for approximately 35% of the total energy consumption and is growing at a rate of 8% annually (Bureau of Energy Efficiency). Commercial buildings in India account for nearly 8% of the total electricity supplied by the utilities. Electricity usage in the sectors has been growing at about 11%–12% annually. Electricity use is primarily from lighting, space conditioning, HVAC (heating, ventilation, and air-conditioning) appliances and equipment (including IT equipment), and water heating (Bureau of Energy Efficiency, Scheme for BEE Star Rating for Buildings – BPO, December 2009).

As the maximum energy-saving potential primarily lies in HVAC or cooling systems, making cooling systems as energy efficient as possible is, therefore, an important component of reducing operating costs. Despite being one of the most important components and their sizeable impacts on facilities, cooling towers are the least maintained utility in industries. Of course, the cooling tower energy consumption is relatively less compared to other utilities but the indirect impact on energy consumption of other systems (Chillers) connected to the cooling tower will be high stressing the need for cooling tower efficiency assessment and improving the same through a reliable Energy Management System for cooling towers and chillers.

The need of the hour is an efficient Energy Management System that can make cooling systems operate efficiently and reliably to their maximum potential even if they are installed in outdoor settings that subject them to extreme heat, dirt, rain, dust and organic contamination. A good energy monitoring and controlling system can help reduce costs and consumption.

When you are looking for an energy management system, you need to consult experts having in-depth knowledge about it. Such units can be challenging to channel, especially when they are connected to each other and also to one or more cooling towers.

The energy consumptions are closely attached to their subsystems’ efficiency, such as compressors, exchangers, pumps, evaporators and more. These subsystems are also profoundly reliant on other equipment such as cooling towers; cooling tower fills, distributors of pumps and chillers, which in turn have a formal and optimum efficiency.

Energy Monitoring System (EMOS) by Cet-Enviro is the most effective and reliable system that automatically records specific power consumption of chillers most accurately 24×7.

EMOS helps to save at least 20% to 40% in chiller energy use. EMOS will continuously collect, analyze and report on chiller operating data through the internet facility integrated into the EMOS system and connected to a cloud-based server.

The critical information collected at the server can be used to manage energy and operating costs on a routine basis and this significantly helps in improving the performance potential of a chiller.

Our Energy Monitoring System provides multiple features such as:
