Energy savings

Johno12345
Hi


I'm looking at my factory for some avenues to save energy, and have certainly come across some projects that have saved thousands on energy, but with an obvious cost to implement. 


The obvious ones like LED lighting, timers etc are all done, so I have started thinking a bit further.


I have 11 charge air blowers, which are 11kW or 13kW, are all pretty old, and have been rewound several times. They cant be changed to variable speed, as the air volume needs to be constant, and need to remain individually controlled. As these things run all day and night, its a significant cost. 


I seem to be a bit sceptical when someone tips up at the door saying they have super energy saving motors, especially when they cant quantify their claims.


Has anyone come across something that gave tangible results on things like this? 


Another one is that someone said putting VSD on pumps and fans, even running them at 100% will give a good energy saving


Thanks, just having a ponder since its Friday

    I know we have plenty of leaks, its hard work keeping on top of them


    we don't dry the air, and the only cooler is an air-air heat exchanger on the compressor, no filters either. I keep the compressors serviced and maintained thoroughly. 


    I think the cooling towers might be a good start, that wont involve every chuffing department across the globe. just need to find someone to talk to about it, maybe get some metering done first
