These are medium-to-large compressors in the AEZ/CAE series with displacements of 40 cc and 50 cc. They use the eco-friendly refrigerant R404A, with an operating temperature range covering -25°C to +59°C, making them suitable for high-, medium-, and low-temperature refrigeration applications.
Robust structural design — The high-strength cast iron crankcase, precision-machined crankshaft, and connecting rod ensure the compressor can withstand harsh conditions and 24/7 long-term continuous operation. Superior valve technology — High-performance spring steel valve plates, specially heat-treated for excellent fatigue and wear resistance, are key to ensuring long service life and low failure rates.
Optimized internal design — Optimized gas flow passages, bearings, and friction pairs reduce internal losses and improve volumetric and motor efficiency, achieving a high coefficient of performance (COP). Broad refrigerant compatibility — Compatible with R404A, R507, and new eco-friendly refrigerants such as R448A and R449A.
The AEZ4440Z/AEZ9440Z (40 cc displacement) is typically used in medium-sized commercial freezer/refrigerated display cases, small cold storage rooms, and large ice cream machines. The AE3450Z/CAE4450Z (50 cc displacement) delivers greater cooling capacity, suitable for higher-load applications such as large freezer display cases, medium-sized cold storage rooms, and industrial cooling equipment.
Q1: What is the difference between the AEZ4440Z and AEZ9440Z?
A: Both have the same displacement (40 cc) and the same power rating (1/3 HP). The main difference lies in the power supply configuration — the AEZ4440Z is single-phase, while the AEZ9440Z is three-phase. Both use R404A refrigerant and have an operating temperature range covering -25°C to +59°C.
Q2: What is the displacement of the AE3450Z and CAE4450Z?
A: The displacement is 50 cc, with a power rating of 3/7 HP. These are the models with the largest displacement and strongest cooling capacity in this group. They are suitable for higher-load applications such as large freezer display cases, medium-sized cold storage rooms, and industrial cooling equipment.
Q3: Why can the compressors in this group achieve high reliability and long service life?
A: The key design features include:
High-strength cast iron crankcase, precision-machined crankshaft and connecting rod, enabling them to withstand harsh conditions and 24/7 long-term continuous operation
High-performance spring steel valve plates, specially heat-treated for excellent fatigue and wear resistance
Optimized gas flow passages, bearings, and friction pairs that reduce internal losses and improve volumetric efficiency
