SANHUA LIQUID INJECTOR (PYF series)

Sanhua PYF Series

1. Dedicated Protection for Scroll/Screw Compressors

• Advantage: Tailored specifically for the injection ports of modern scroll and screw technology.

• Benefit: Provides a highly reliable safety net for high-compression applications, preventing the internal heat build-up that can lead to catastrophic scroll or screw damage.

2. Automatic, Power-Free Operation

• Advantage: Operates entirely based on mechanical thermal expansion (no sensors, wires, or controllers needed).

• Benefit: Provides failsafe protection even if the system’s electronic controls or power fail, ensuring the compressor is never left unguarded against overheating.

3. Optimized System Efficiency

• Advantage: Precise set-point calibration ensures the valve only opens when absolutely necessary.

• Benefit: Minimizes the impact on system efficiency by avoiding unnecessary liquid injection, ensuring the compressor runs at its highest possible performance while staying safe.

4. Compact “Fit-and-Forget” Installation

• Advantage: Small size and simple bulb-strapping installation.

• Benefit: Allows OEMs to easily integrate discharge temperature control into tightly packed condensing units or small cold-room systems without adding complexity to the electrical circuit.
