1）These are Y-suffix models that use the eco-friendly refrigerant R134a. Displacement ranges from 12.05 cc to 16.0 cc, with power ratings extending from 1/3 HP to 7/16 HP. Three models form a clear power gradient, facilitating precise selection based on cooling load requirements.
2）They feature an optimized design with high-efficiency valves and motors — optimized suction and discharge valves combined with high-efficiency motors ensure quick response and high compression efficiency, improving overall system energy efficiency. The heavy-duty structural design — with a robust crankcase, high-strength crankshaft, and connecting rod — enables the compressor to withstand the challenges of heavy-load startup and long-term continuous operation.
3）Built-in overcurrent, overload, and phase-loss protection devices enhance system safety. The optimized cooling system ensures that the motor and compressor operate within safe temperature limits, extending service life. The operating temperature range covers -25°C to +15°C, making them suitable for medium- and low-temperature refrigeration applications. Typical applications include commercial freezer display cases, cold storage rooms, refrigeration worktables for kitchens, ice machines, beverage coolers, and more.
Q1: How to select among the CAE 3440Y, 4448Y, and 4456Y models? A: The three models form a clear power gradient — displacement increases from 12.05 cc to 16.0 cc, with power ranging from 1/3 HP to 7/16 HP. Taking the +7.2°C condition as an example, cooling capacities are 731W, 892W, and 1009W respectively. For applications with a smaller cooling load, choose the 3440Y; for heavier loads, choose the 4456Y.
Q2: What refrigerant do the CAE series Y-suffix compressors use?
A: They use the eco-friendly refrigerant R134a (zero ozone depletion potential, ODP), which is the mainstream choice for replacing R12 refrigerant. They are widely used in commercial freezer display cases, cold storage rooms, refrigeration worktables for kitchens, ice machines, beverage coolers, and other equipment.
Q3: What is the operating temperature range of the CAE series?
A: The operating temperature range covers -25°C to +15°C, making it suitable for medium- and low-temperature refrigeration applications. For lower temperatures (e.g., -40°C), dedicated LBP (low-back-pressure) models should be selected.
Q4: What protection functions do the CAE series compressors have?
A: They feature built-in overcurrent, overload, and phase-loss protection devices. When the motor temperature is too high or the current is excessive, the thermal protector (Klixon) will automatically disconnect the circuit and automatically reset after cooling down. This enhances system safety and prevents motor burnout.
