Available from HPC Compressed
Air Systems, the HPC Kaeser 2nd
generation Sigma Air Manager
(SAM) with adaptive 3-D-Control
can help users optimise the
availability and energy efficiency of
compressor and blower stations alike.

With a powerful industrial PC at
its core, the SAM not only controls
and monitors the system as a whole,
it provides the user with a high
degree of transparency of operations
processes, energy consumption and
costs. The latest version’s adaptive 3-
D-Control considers three factors
that affect energy-efficient
compressor control within a
compressed air station:
Switching losses associated with
compressor start-up and
shutdown
Additional energy consumption
for pressure increases above the
required pressure
Control losses resulting from
idling and FC losses
To ensure optimum performance,
the SAM constantly analyses the
relationship between these factors,
calculates the best result and controls
the compressors or blowers
accordingly.
