NXHE SERIES

TWO-STAGE ROTARY SCREW AIR COMPRESSORS 90-250 KW

FS-CURTIS WAS FOUNDED org BOTH.

More than 160 years ago, the FS-Curtis way of doing business was established through two key commitments:
a dedication to building quality products and a dedication to responsive customer service.

Over the decades, the company and its products have evolved through innovation and new technologies. But those
commitments to quality and service remain unchanged. Today, just as in 1854, FS-Curtis customers can depend on
our products for reliable, long-term service. Equally as important, they can depend on getting the same from our people.

A HISTORY OF EXCELLENCE

Compared to single stage compressors, a two-stage is much closer to isothermal compression. This is achieved by injection of fresh oil between the stages which reduces the inlet temperature to the second stage. This lower inlet temperature increases efficiency by reducing the compression ratio between the stages. In addition, leakage between the rotor seals is significantly reduced resulting in outstanding volumetric efficiency.

Two-stage air compressors are closer to the ideal isothermal compression
Reduced leakage increases volumetric efficiency
saves 10-15% of energy compared to single stage compressors
Increases flow 10-15% compared to single stage compressors
Lower pressure differential increases efficiency and reliability
Low heat load
Easy maintenance and service
Lowest life-cycle cost of any compressor on the market

WHEN COMPARED TO SINGLE STAGE, TWO-STAGE COMPRESSORS CAN SAVE UP TO 15% IN ENERGY CONSUMPTION AND OFFERS 15% MORE FLOW.

ICOMMAND-TOUCH

TAKE CONTROL OF YOUR WORLD.

With the premium iCommand-Touch, a full-color screen displays graphs which capture and track factual, real-time air usage by the hour, day, week and month. Historical data can be retrieved at any time at the touch of the screen.
Data trending keeps your finger on the pulse of your entire compressed air system.
Continuously tracks pressure, temperature, air quantity and usage to easily diagnose and optimize your plant’s air system.

Trending and Graphing Capabilities

Graph information can be conveniently downloaded to SD card for historical records, troubleshooting and quality control measures.

One-Touch Status Review At A Glance:

Main Screen: Displays image of compressor with red dot indicator spotlighting issues in the system, which reduces time in trouble shooting.

Pressure: Continuously tracks pressure range by day, week and month. This allows quick identification of pressure variations that affect plant operations.

Air Circuit & Oil Circuit: Quick diagnosis of key component operation within the air and oil circuit

Temperature: Real-time monitoring and trending of critical oil temperature enable early identification of potential shutdown and downtime.

Air Quantity: Monitors cubic feet of air usage, pinpointing peak production or down times in your operation.

Usage: Tracks how long machine is on, off or in standby. This allows you to analyze usage factor in your plant based on the operation of your compressor.

Maintenance: Tracks and displays hours of usage of critical components—oil filter, inlet filter, air/oil separator and motor—and timetable for replacement and/or maintenance.
