Product details

Danfoss MLZ030T4LC9A Scroll Compressor | 5 HP

Product Description:

The Danfoss MLZ038T4LC9A (Part No. 121L8644) is part of the specialized Blue Series, precision-engineered for medium-temperature (MBP) refrigeration. With a robust 5 HP output, this compressor is a staple in UAE supermarket refrigeration, providing stable cooling for walk-in chillers and large display cases. Optimized for HFC refrigerants like R404A, R134a, and R407A, it ensures superior seasonal energy efficiency compared to standard reciprocating units. Its hermetic scroll design offers quiet operation and minimal vibration, which is critical for urban retail environments. Built to endure the Middle East’s high-ambient thermal stress, it features a 100% suction-gas cooled motor and utilizes PVE oil for maximum system stability.

Key Features & Benefits:

  • Industrial 5 HP Performance: Ideal for medium-to-large commercial refrigeration tasks requiring consistent duty cycles.
  • Multi-Refrigerant Flexibility: Fully compatible with R404A, R134a, R407A/C/F, and R507 to suit various regional standards.
  • High Efficiency Scroll Geometry: Reduces power consumption, a key advantage for 24/7 cooling operations in the UAE.
  • PVE Oil Advantage: Factory-charged with PVE oil, which is non-hygroscopic, significantly reducing the risk of acid formation in the system.
  • Low Noise Design: Provides a quieter working environment compared to traditional compressors, perfect for commercial malls.

FAQs:

  • Q: Why use PVE oil instead of POE in the UAE?
  • A: PVE oil doesn’t absorb moisture like POE does, which is a major advantage during field service in humid or high-ambient regions like Dubai.
  • Q: Can this replace a 5 HP reciprocating compressor?
  • A: Yes, it is a common efficiency upgrade for systems originally designed with reciprocating units.
  • Q: Does it include internal motor protection?
  • A: Yes, it features internal protection against overheating and overcurrent to ensure long-term reliability.
