A variable speed drive compressor saves energy by matching output to demand, and the savings depend on your load pattern.
Why VSD Saves Energy
Fixed-speed compressors waste energy during unload and blow-down, while VSD machines simply slow down.
Estimating the Savings
Compare the specific power and part-load behaviour of each option against your measured flow profile.
When VSD Pays Back
Plants with wide, shifting demand recover the extra cost fastest, while steady full-load plants save less.
