YLG40Z—YLG60G
Blait
Blait’s Industrial Semi-Hermetic Screw Refrigeration Compressor (Model Range: YLG40Z-YLG60G) is engineered for reliable, continuous cooling in demanding industrial environments. Leveraging advanced screw rotor technology, this compressor delivers pulsation-free cooling capacity, making it ideal for cold storage warehouses, food processing plants, and industrial cooling projects. Its semi-hermetic structure ensures superior sealing (reducing oil leakage by 90% vs. open-type compressors) and long service life, while its flexible design adapts to diverse power supplies and refrigerant types.

Precision-machined twin screws minimize internal leakage, boosting volumetric efficiency by 15% compared to traditional piston compressors. The rotor profile reduces airflow resistance, enabling consistent cooling output even under variable loads (e.g., daily temperature shifts in cold storage). This design also lowers exhaust temperature, extending lubricant life.
The compressor supports a range of industrial refrigerants, including R22, R404A, R507A, and low-GWP (Global Warming Potential) options. Its adaptive system adjusts to refrigerant properties, making it suitable for both medium-temperature (HVAC) and low-temperature (freezing) applications—from supermarket refrigeration to industrial freezing lines.
The screw mechanism’s balanced rotation reduces vibration to <0.1 mm displacement, protecting adjacent equipment and lowering noise levels to ≤70 dB(A). This makes it perfect for noise-sensitive environments like pharmaceutical labs and commercial refrigeration (supermarkets).
Blait’s semi-hermetic screw compressors stand out for industrial-grade reliability and customized solutions:
Advanced Oil Management: An internal oil separation system with ≥99.9% efficiency reduces oil carryover, minimizing maintenance costs and extending component life.
Global Adaptability: Designed for 380-480V/3-phase/50-60Hz power supplies, supporting international industrial projects across regions.
Rapid After-Sales Service: A global network of service centers provides fast spare parts delivery and on-site maintenance, ensuring minimal downtime for critical cooling systems.
