Built around the
required pressure.
Two-stage and four-stage compression architectures allow the
NTC Series to serve low- and high-pressure industrial applications.

Two-Stage Compression
For lower-pressure applications, the compressor uses a two-stage
architecture. Depending on pressure requirements, the system can
incorporate inter-stage and after-stage cooling.
1.5 – 4.5 BAR

04
Four-Stage Compression
For high-pressure applications, a multi-core four-stage system
works together with a four-stage shell-and-tube heat exchanger
to support efficient compression and cooling.
4.5 – 9 BAR
