The Gram Cylinder Head Cover is a protective component used in Gram compressors to cover the cylinder head. The cylinder head is a critical part of the compressor, where refrigerant is compressed and directed through the system. The cover helps protect the cylinder head from contaminants, debris, and environmental factors, ensuring smooth and efficient operation. By maintaining the integrity of the cylinder head, the cover contributes to the overall reliability, performance, and longevity of the compressor in refrigeration and HVAC systems.
