Nikkiso Clean Energy & Industrial Gases Group

TURBO Process Systems
Compressor [TC] Series


Compressor loaded Expanders with high capacity bearings. The expander and compressor wheels are mounted on a common shaft. The energy from the expander wheel powers the compressor wheel – helping to recover as much energy as possible to maximize cold production and overall plant efficiency.

Features & Benefits

  • Compact footprint
  • “Zero leakage” inlet guide vanes
  • Rugged rotor design
  • Components individually balanced for ease of field replacement
  • Tapered shaft wheel attachment for field interchangeability
  • Labyrinth shaft seal design minimizes seal gas consumption and prevents process stream contamination
  • Shaft-driven boost compressor reduces power consumption, increasing plant efficiency
