MULTI-STAGE COMPRESSION

Built around the
required pressure.

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

NTC Two Stage Air Suspension Compressor

02

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

NTC Four Stage Air Suspension Compressor

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

CORE TECHNOLOGY

Precision at
high speed.

Every key component is engineered around high-speed operation,
energy efficiency, stability and intelligent compressor control.

01
VS-PMS Motor
Up to 98% maximum efficiency, high-speed operation
from approximately 20,000 to 220,000 RPM and precision speed control.
02
Aerodynamic Impeller
Precision aerodynamic design supports a wide operating range,
surge margin and high efficiency using high-strength materials.
03
Aerostatic Air Bearing
Air is used as the lubricant, providing an
oil-free and contactless bearing architecture
with reduced routine maintenance.
04
High-Speed VFD
Variable-frequency control is optimized for high-speed motor
operation and works with PLC control for precise speed management.
05
Shell & Tube Heat Exchanger
Integrated cooling supports operating efficiency and durability
while recovered heat can also be reused for other processes.
06
Automatic Safety Control
Real-time monitoring, surge protection, Modbus RTU support,
PLC compatibility and UPS protection help improve operating reliability.
