Demand based sequencing
In developing SAM, Kaeser evaluated what a customer might want from their compressed air system, and prioritized it:
Compressed Air – Of course the top concern is they need compressed air. Judging from the amount of money customer’s actually pay to produce compressed air, they REALLY want compressed air.
Reliability – And if the customer REALLY wants compressed air, then it is a safe bet that most customers mean they want a reliable source of compressed air.
Stable pressure – Historically speaking, most customers equate a reliable system with a stable system pressure. Quite commonly, the way a customer stablaizes the system pressure (modulation control & high system pressure) is quite inefficient.
Safety – Once a reliable air supply is addressed, most customer’s become concerned with how they can make the production of compressed air safer to personnel.
Unfortunately, it is true that many customers stop spending money on their compressed air station at this point. On the other hand, more customers are becoming aware of a very large potential to save money. So, even the lowest priorities are getting more attention, including...
Efficiency – The fact is that rising energy costs are causing more customers to consider investing in improving compressed air system efficiency. And if you recall the 8:1 rule of thumb (which states that a typical compressor requires 8 HP worth of electrical energy to produce 1 HP worth of pneumatic energy), it becomes clear that a little bit of additional expense applied to improving efficiency can result in large returns.
Remote monitoring – Of course, knowing where to spend that money to get the largest returns becomes quite a trick. So, wouldn’t it be nice if it was possible to automatically collect data which would steer you in the right directions. And while we’re at it, wouldn’t it be nice if that data could then show just how much money was saved by making improvements!
Yeah! and while we’re at it, it sure would be nice if you could verify the condition of the compressed air system from remote locations (like an engineer’s office or how about via the internet when your out of town!

Every 10 psig decrease in system pressure saves 14.5% of electrical input energy:
5.0% energy reduction
+ 9.5% artificial demand reduction
14.5% total electrical reduction
Another 10% savings is likely due to optimized compressor duty cycle.
