Danfoss Scroll Compressors
For Light Commercial and AC applications, Precision cooling
- Discharge check valve: no reverse rotation hence no shutdown noise.
- Radial scroll compliance: Good resistance to liquid flood back.
- Axial scroll compliance: low starting current.
- Oil Injection: Good lubrication at fierce conditions
- Lead-free bearings: high reliability even with low lubrication
- Patended internal protection combined with HOOP(Hot oil over protector) thermal valve: excellent reliability standard dimensions and tubing: ideal for both new installations and replacement markets.

- Boost Cooling capacity and efficiency with vapor injection in low temperatures
- Danfoss proposes the optional economizer kit to boost compressor efficiency and capacity with vapour injection.
- The system uses a liquid subcooler circuit. During the liquid subcooler process, some liquid
- Refrigerant evaporates in the economizer and is injected in to the scroll set at intermediate pressure.
- This provides additional cooling capacity thanks to subcooling in the economizer and increase efficiency of the system.
- The effect of vapor injection increases together with the increase of system pressure ratio.
