For Light Commercial and AC applications, Precision cooling

H series

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.
