Built for Next-Generation Efficiency and Low-GWP Systems

From low-GWP comfort cooling to transcritical CO₂ refrigeration, Toshiba Rotary compressors provide a flexible, variable-speed platform designed for modern HVAC and refrigeration systems.

Supporting R-454B, R-32, and CO₂ (R-744), the lineup covers applications from residential and light commercial HVAC to VRF, chillers, display cases, condensing units, mini racks, and heat pumps.

With permanent magnet motor technology and inverter-driven operation, these compressors deliver improved efficiency, reduced footprint, and strong part-load performance.

For OEMs already using scroll or rotary compressors, Toshiba Rotary provides a practical “drop-in” upgrade—enhancing performance without requiring a full redesign.

Key Advantages

  • High Part-Load Efficiency: Optimized for real-world operating conditions
  • Compact Design: Smaller footprint with up to 30–50% weight reduction
  • Variable-Speed Operation: Inverter duty and VFD controlled
  • Broad Applications: HVAC, refrigeration, CO₂ systems, and heat pumps
