Compressor Counterweights / Balance Weights
FRING manufactures high-density compressor counterweights (balance weights) using powder metallurgy, allowing precise mass distribution at lower cost than cast iron. These weights reduce vibration in hermetic and semi-hermetic compressors for HVAC and refrigeration systems, with density tailored to customer requirements.
