What is the expected lifespan of the 2-Cyl RFC Compressor?

With regular maintenance (filter replacement every 6 months, oil check annually), the compressor achieves a service life of 12–15 years. Poor operating conditions (e.g., ambient temperature >35°C) may reduce lifespan by 20% .

Which refrigerants are compatible with this compressor?

It is fully compatible with R-134a (hydrofluorocarbon) and R-600a (hydrocarbon), the two most widely used eco-friendly refrigerants in modern fridges. Mixing refrigerants is strictly prohibited .

Can it be used for commercial walk-in coolers?

No. This model is engineered for fridge-specific load demands (≤7.8 kW). Commercial walk-in coolers require compressors with ≥15 kW capacity, such as 6-cylinder variants .

How does cast iron construction improve performance?

Cast iron’s high thermal conductivity reduces cylinder temperature by 8–10°C during operation, minimizing refrigerant leakage risks. Its rigidity also cuts vibration by 25% compared to aluminum compressors .
