hello
im new at this so please bear with me. im trying to figure out a couple of things i look after a large refrig plant with 6 large screws and 4 piston machines im try to get things to run better on power and starting.my boss has been talking to powerboss he is gunho about putting in these machines but im not sure. here is a couple of questions. 1/a screw compressor has a varying load the machine will load and unload on pressure but once my machine gets to about 70%load they become inefficient .but with a drive a can slow my machine down and keep it loaded. but powerboss is telling me that is wrong and iwould be better of with a powerboss but i disagree with them. they are saying that they can save around 12-20% on the power but they will not put one in so we can try it these motors are around 220-265kw. 2/ i have a condensor fan turning on and off on pressure i want to install a vsd drive to these motors with a pid lood so then i can maintain a constant pressure .but once again powerboss is telling me that this is the wrong way to do it.but iknow it is right my boss is leaving this one in my hands please help me. thanks fridgie100 |
