Panasonic C-SCN903H8H / H8K Scroll Compressor – 12HP R407C refrigeration compressor

Both compressors possess powerful "heart" performance, providing robust power for large-scale systems:

•   Super-Large Displacement and Cooling Capacity: Featuring an ultra-large displacement of 205.4 cm³/rev and a robust cooling capacity of 34.9 kW, they are veritable "12HP flagship models."

•   Excellent Energy Efficiency: With a high Coefficient of Performance (COP) of 3.09 W/W, they ensure energy economy while delivering massive cooling output.

•   Wide Operating Range Adaptability: The evaporation temperature range covers -15°C to 12°C, flexibly coping with various scenarios including air conditioning, heat pumps, and medium-to-low temperature refrigeration.

•   Mature Motor Technology: Equipped with a proven three-phase induction motor, it offers high starting torque and stable, reliable operation.

Safety and Reliability Design: Durable Industrial-Grade Quality

Both compressors feature built-in multiple protections to ensure long-term stable operation in demanding environments:

•   Comprehensive Motor Protection: Built-in direct-off type protector can quickly cut off the circuit in case of abnormal current or temperature, safeguarding motor safety.

•   High-Spec Electrical Insulation: The motor adopts Class E insulation and can operate normally within a wide voltage range of 342~456V, effectively coping with grid fluctuations.

•   Robust Mechanical Structure: The main and auxiliary bearings utilize high-performance rolling bearings, effectively withstanding the impact caused by frequent start-stop cycles.

•   Efficient Contaminant Protection: A metal mesh filter is built into the suction port, effectively intercepting impurities such as welding slag and metal debris in the system.

•   Stable Operation in Wide Temperature Range: The maximum design discharge temperature reaches 135°C, enabling it to adapt to more demanding operating conditions.

Environmental and Flexible Adaptability

The biggest difference between the two models lies in their refrigerant compatibility, offering users distinct choices:

•   C-SCN903H8H: The Standard Eco-Friendly Choice

   Compatible with various environmentally friendly refrigerants including R407C, R448A, R449A, R134a, R513A, and R404A. This model is a standard "versatile all-rounder," meeting the application requirements of the vast majority of mainstream eco-friendly refrigerants, making it an ideal choice that balances performance and versatility.

•   C-SCN903H8K: The Extended Compatibility Choice

   On the basis of the H8H, it further supports R507C refrigerant. R507C has advantages in low-temperature refrigeration fields; therefore, the H8K model is more suitable for projects with special refrigerant requirements or those that may need to switch to R507C systems in the future, offering stronger expandability.
