Benefit from large-scale air separation

Large-scale, reliable and highly-efficient compressor packages. Reduce your operational and maintenance costs, while experiencing shorter setup times and easier site construction

Robust main air compressor unit

The RT-Series main air compressor unit features a three-stage radial single-shaft design for high flow levels and superior efficiency. Top performance over your product’s lifetime

Drive train know-how

Trusted turbomachinery provider. Decades of experience in employing both steam turbine and electrical motor drive trains to power main air compressors

Interstage coolers

Coolers are a critical part of your main air compression process. That’s why our interstage coolers use a proven water-in-tube/air-in-shell design with an integrated water demister to ensure optimum performance

Global sourcing network

We’re always close by. Further improving your CAPEX and fitted to your exact specifications, all external components supporting your main compressor unit can be sourced and then packaged regionally

Technical description of the RT-Series single-shaft turbocompressor

A direct answer to growing demand for larger and OPEX optimized air supply levels in today’s air separation units (ASUs), the single-shaft, three-stage radial-flow RT-Series combines the best in our aerodynamic competence to deliver ultra-efficient stage and impeller design. In full compliance with API 617 and 614 (oil system) standards, the RT-Series is developed for all main air separation applications.

By using a modular, simplified design and a free-arrangement packaging concept the RT-Series compressors

  • shorter delivery time
  • lower OPEX costs
  • ensure maximum reliability
  • minimize maintenance downtime
