Yes, this reciprocating compressor is highly adaptable and fully compatible with R404A, as well as other modern refrigerants like R507A and R448A. Ensure that the expansion valves and system lubricants are correctly matched to the chosen refrigerant during the retrofit process to maintain peak efficiency.
The integrated 120W/140W (220V) crankcase heater automatically activates when the compressor cycles off. This prevents the refrigerant from migrating into the oil and condensing, which would otherwise cause oil foaming and inadequate lubrication during the next startup sequence, protecting the mechanical integrity of the unit.
The 4VB12.2G model, along with our other units in this series, is designed to operate on a robust three-phase industrial power supply. It seamlessly accommodates 380-420V at 50Hz or 440-480V at 60Hz, ensuring stable and continuous operation across various regional power grids without requiring external voltage transformers.
Not at all. While termed "open-type" regarding the unit's external structural framework—which allows for enhanced ambient cooling and easier maintenance accessibility—the compressor itself features a highly secure, hermetically sealed internal environment with advanced shaft seals that completely prevent refrigerant leakage and block external moisture or dust ingress.
