Product Description

| Product Description

I. Product Advantages

Refrigerant & Operating Conditions: The entire series is compatible with R22 refrigerant and strictly follows medium/high back pressure (MBP/HBP) application standards, with an evaporation temperature range typically covering -5°C to +12°C, perfectly matching commercial refrigeration, fresh-keeping display, and food processing equipment in conventional temperature zones.
Power Adaptability: Uses 208–240V / 50Hz single-phase power supply with a wide voltage design to accommodate grid fluctuations in different regions. Built-in Class F insulation (rated 155°C) large-volume motor with ample winding heat dissipation area effectively reduces the risk of thermal damage even in high-temperature machine rooms or poorly ventilated environments.
Lubrication Management: Factory pre-charged with 450cc of dedicated refrigeration oil, with precisely calibrated oil levels ensuring oil film continuity under various tilt angles and during start-stop transients, reducing bearing wear.
Operation Quality: Through optimized piston motion inertia and valve group airflow pulsation, the overall vibration amplitude is reduced by approximately 15% compared to the previous generation, with noise levels controlled within the 52–58 dB(A) range (varies slightly by model), suitable for open commercial spaces such as supermarkets and convenience stores where quiet operation is required.

| Basic Parameters

I.Model Gradient: Fine-Tuned Displacement and Horsepower for Precise Cooling Matching

Each model forms a clear power tier through variations in bore/stroke combinations and motor output characteristics, enabling easy selection based on specific needs:

Model	Displacement (cc)	Rated Horsepower	Typical Cooling Capacity Reference (R22, Evap Temp 7.2°C)	Core Positioning
AEZ4425E	4.50	1/5 HP	Approx. 550–650 W	Entry-Level Economy – Suitable for small beverage coolers, tabletop refrigerated display cases, medical incubators, and other micro-load scenarios. Its low starting current (approx. 12A peak) reduces the burden on low-power circuits.
AEZ4430E	5.70	1/4 HP	Approx. 750–850 W	General-Purpose Mainstay – Widely used in 1.2–1.8m commercial upright refrigerators, island freezers, and small-to-medium fresh-keeping rooms. Maintains high energy efficiency ratio (EER ≥ 2.1) even at ambient temperatures of 32°C, balancing cost and performance.
AEZ4440E	7.55	1/3 HP	Approx. 950–1050 W	Fast Cooling Type – Ideal for ice makers, quick-freeze cabinets, commercial ice cream display cabinets, and other equipment requiring rapid temperature pull-down. Its high-torque motor combined with efficient gas valves ensures swift response during high-pressure differential starts.
AEZ9440E	7.55	1/3 HP	Approx. 950–1050 W	Enhanced Starting Torque Version – Same displacement as AEZ4440E, but specifically optimized for low-voltage starting (as low as 195V) and frequent start-stop conditions. By increasing the start capacitor capacity (depending on specific order configuration) or adjusting the auxiliary winding turns, the starting torque is improved by approximately 20%. Particularly suitable for unstable grid conditions such as older buildings, mobile food trucks, or solar-assisted power supply.
AE3450E	9.40	3/7 HP	Approx. 1150–1280 W	Large-Displacement Flagship – Designed for large-capacity freezers (>600L), high-temperature kitchen cold rooms, or medium-sized cold chain terminals with frequent door openings. Its ample displacement ensures the refrigeration system maintains rated conditions even in high-temperature weather (ambient temperature 43°C), reducing the risk of compressor "hunting."

Note: Cooling capacity data represents laboratory nominal values. Actual performance depends on heat exchanger configuration and expansion valve selection.

II. Low Noise and Vibration, Ideal for High-End Commercial Settings

Through optimized piston motion inertia and valve group airflow pulsation suppression technology, the overall operation quality is significantly enhanced:

Noise as low as 52 dB(A) (AEZ4425E no-load test value), equivalent to library ambient volume, suitable for open display areas in convenience stores, boutique supermarkets, and similar settings.
Vibration reduced by 15%, minimizing cumulative pipeline stress, lowering the risk of weld cracking and refrigerant leakage, and indirectly extending system lifespan.
Excellent oil film stability: The precisely pre-charged 450cc of oil, combined with optimized oil passage channels, ensures adequate bearing lubrication even during tilted installation (≤ 30°) or frequent start-stop cycles.
