Design Philosophy

Horizontally split compressors are generally used in high flow and low pressure applications. The GE product line covers all market needs from standardized equipment to cutting-edge compression solutions such as state-of-the-art compressors for Liquefied Natural Gas plants. We can also supply the complete range of products for installations including gas turbines, compressors, control systems and air coolers.

Applications

Low to medium pressure service: Refrigeration compressor, gas production and processing applications, ethylene process compressors, refinery applications, carbon dioxide compression trains for urea plants, and other industrial applications.

Testing Capabilities

The units can be string or full-load tested in our shop, with both ASME PTC 10 type I or type II criteria, thus concentrating the responsibility for the complete train in the hands of a single source supplier.

Internal test rigs with electric motor drivers and steam turbines are available for standard shop tests and open loop air performance tests.

External test rigs with special facilities for string and full load tests of complete turbocompression trains ensure full compliance with customer-specific requirements.

Our Virtual Witness System allows customers to monitor tests remotely and securely via the Internet.

In addition to open-loop air and closed-loop gas options, and full-load, full-pressure mechanical testing, we offer a new high speed balancing system.
