Brand New Tecumseh R404a Piston Compressor CAE2446Z TAJ2446Z CAE2464Z TAJ2464Z Price for Refrigeration & Heat Exchange Parts

Product Overview & Description

1. Basic Positioning

This series comprises high-performance, large-displacement, high/medium back-pressure hermetic piston compressors designed for commercial refrigeration equipment. Belonging to Tecumseh's renowned "AE/AJ" series, they are famous for their robust durability and powerful cooling capacity.

2. Model Breakdown

• Prefix: `CAE` and `TAJ` denote different series and electrical configurations, but their performance parameters are very similar. The `T` often indicates enhanced built-in protection devices and electrical features.

Number Segment: `2446` and `2464` are key, specifying the compressor displacement.

• `24` represents a displacement of 2.4 cubic inches (approx. 39.3 cm³). This is a relatively large displacement, meaning it can compress more refrigerant per cycle, resulting in stronger cooling power.

• `46` and `64` are typically version codes for internal design and refinements, potentially indicating minor improvements in efficiency, noise, or materials.

3. Key Technical Parameters (Typical values, please refer to the official datasheet for specifics)

• Refrigerant: Primarily suitable for R404A, also compatible with R134a, R22 (phased out due to environmental regulations), etc.

• Application Range:

• High/Medium Back-Pressure Applications:Such as commercial refrigerated cabinets, display cases, ice cream makers, beverage coolers, kitchen refrigerators, salad bars**, etc.

• These applications typically require strong cooling capacity at medium evaporation temperatures (e.g., -10°C to +10°C).

• Power Supply: Supports various voltages and frequencies (e.g., 208-230V, 50/60Hz) depending on the specific model.

• Lubricant:Typically uses Alkylbenzene oil or POE ester oil.

4. Product Description Summary

The Tecumseh CAE2446Z / TAJ2446Z / CAE2464Z / TAJ2464Z series are the "workhorses" of the commercial refrigeration sector. With their large displacement and robust design, they provide the core power for commercial equipment requiring consistent and efficient cooling. They feature a compact structure, high reliability, and are easy to integrate into various equipment designs.

Application field

1. Commercial Display & Merchandising Cabinets

• Vertical/Horizontal Beverage Coolers: Used for refrigerating canned and bottled beverages, requiring rapid pull-down temperature and stable maintenance of冷藏 temperature (approximately 2-8°C).

• Ice Cream Display Cases: Used for the display and sale of both soft-serve and hard ice cream, requiring maintenance of low temperatures around -18°C to -12°C. The large displacement handles the thermal load from frequent door openings.

• Deli/Dairy Display Cases: Used in supermarkets for displaying items like cheese, yogurt, and luncheon meats, typically operating at 0-5°C.

• Convenience Store Multi-Deck Display Cases:Refrigerated cabinets storing ready-to-eat foods like sandwiches, salads, and bento boxes.

2. Commercial Kitchen & Cold Processing Equipment

• Worktop Refrigerators/Freezers: Used in restaurant back-of-house for storing daily ingredients; the core refrigeration units in a commercial kitchen.

• Salad Bars/Refrigerated Counters: Require internal refrigeration to keep ingredients fresh.

• Pizza Prep Tables/Ingredient Stations: For refrigerated storage of pizza dough and various toppings.

• Patisserie Display Chillers: Used in bakeries and pastry shops to keep cakes and pastries fresh and visually appealing.

3. Specialized Refrigeration Equipment

• Hotel Minibar Refrigerators: Higher-end models demanding certain levels of reliability and quiet operation.

• Medical Refrigeration Cabinets: Used for storing pharmaceuticals and vaccines (typically at 2-8°C), where temperature stability and reliability are critical.

• Small Walk-in Cold Rooms: Serving as the refrigeration heart for small冷藏 (approx. 0-10°C) walk-in coolers.
