Product details

Danfoss MLZ076T4LC9A Scroll Compressor | 10 HP

Product Description:

The Danfoss MLZ076T4LC9A (Part No. 121L8654) represents the high-capacity end of the specialized MLZ scroll range, optimized specifically for medium-temperature (MBP) refrigeration applications. Delivering a robust 10 HP output, this unit is a primary choice for large supermarket central racks, industrial cold storage warehouses, and high-capacity process chillers across the UAE. Built for multi-refrigerant flexibility with R404A, R134a, and R407A, it ensures significant energy savings over traditional reciprocating technology. Its advanced scroll design offers smooth, quiet operation with minimal vibration, while the factory-charged PVE oil provides superior moisture resistance, ensuring long-term mechanical stability in the extreme high-ambient conditions of the Middle East.

Key Features & Benefits:

  • Massive 10 HP Cooling Capacity: Engineered to handle large-scale refrigeration loads in commercial and industrial environments.
  • Medium-Temperature Optimization: Precision-designed for MBP cycles, offering higher volumetric efficiency than adapted HVAC units.
  • Versatile Refrigerant Support: Compatible with R404A, R134a, R407A/C/F, and R507 to meet various site requirements.
  • PVE Oil Technology: Uses non-hygroscopic PVE oil, which reduces the risk of system contamination and acid formation compared to POE.
  • Quiet & Durable Operation: Features a hermetic scroll design that minimizes noise pollution and mechanical wear in 24/7 duty cycles.

FAQs:

  • Q: Is the MLZ076T4LC9A suitable for large cold stores in Dubai?
  • A: Absolutely. It is specifically designed to handle the high-ambient thermal loads and continuous operation required in the UAE.
  • Q: Can this compressor be used in a tandem configuration?
  • A: Yes, it is ideal for use in manifolded rack systems to provide scalable cooling for large supermarkets.
  • Q: Why use PVE oil instead of POE?
  • A: PVE oil does not react with water to form acid, which is a major advantage for maintenance in humid or high-ambient regions.
