Features & Advantages:
This group features the T-suffix models within the CAJ/TAJ series, utilizing R22 refrigerant. Displacements range from 15.20 cc to 24.20 cc, with power ratings extending from 5/8 HP to 1-1/8 HP. The three models form a clear power progression — the 9480T as the entry level (5/8 HP, 15.20 cc), the 9510T as the mid-tier (1 HP, 18.30 cc), and the 9513T as the top tier (1-1/8 HP, 24.20 cc).
Cooling capacity increases steadily with displacement: at the +7.2°C condition, capacity progresses from 2103 W (9480T) to 3272 W (9513T), covering the load requirements of small-to-medium commercial refrigeration equipment. For each displacement, both single-phase (CAJ) and three-phase (TAJ) power versions are available, offering flexible matching to different supply configurations. All models share a unified 887 cc oil charge, ensuring lubrication system consistency and simplifying maintenance management. This group is especially well-suited for medium-to-high temperature refrigeration applications such as beverage coolers, display cases, and small cold rooms.
Q1: How do I select the right CAJ/TAJ compressor model for my refrigeration system?
A: Selection is primarily based on the required cooling capacity and application temperature range. This series covers an evaporating temperature range of -15°C to +15°C, suitable for Medium/High Back Pressure (M/HBP) applications. The numbers in the model designation (e.g., 9480, 4519) indicate different displacements and power ratings — for example, the CAJ9480T is 5/8 HP, while the CAJ4519Z is 1-3/4 HP. You should choose the appropriate model by cross-referencing your system load and refrigerant type (R22, R404A, R134a, etc.) against the technical specification sheet.
Q2: What is the main difference between CAJ and TAJ series compressors?
A: The primary difference lies in the power supply. The CAJ series is typically single-phase (220–240 V, 50 Hz), while the TAJ series is the three-phase version. Additionally, suffixes such as "U" and "N" denote models designed for specific refrigerants — "U" for R290 and "N" for R1234yf, respectively.
