Low Temperature Semi Hermetic Screw Compressor

Availability:
Quantity:

Product model:(YLG60Z-192...YLG90G-250)


Engine displacement:

(50Hz): 192m³/h~250m³/h

(60Hz): 232m³/h~302m³/h


Features:

Under medium and low temperature conditions, the compressor demonstrates high efficiency, energy saving, and environmental friendliness. Refrigerants suitable for use include R22, R404A, R507A, etc.


Performance advantages:

  • The YZ57 tooth profile line, composed of arcs and higher-order curves.

  • Equipped with a standard PTC110°C temperature sensor.

  • Suitable for high-pressure working conditions, with a pressure difference resistance of 2.0MPa.

  • Equipped with a standard INT69 FSY protection module.

  • The area utilization coefficient has reached 0.41 & 0.45.

  • Equipped with oil flow switch and monitoring of oil circulation as standard.

  • The leakage triangle area is smaller than that of conventional wire, effectively reducing leakage losses.
