The Vilter Cover, Water Jacket – Ammonia & R22 is a protective component designed for Vilter compressors using refrigerants such as ammonia (R717) and R22. This cover encloses the water jacket, which helps regulate the temperature of the compressor by circulating coolant or water. By protecting the water jacket, the cover ensures effective heat management, preventing overheating and maintaining efficient compressor operation, especially in industrial refrigeration systems using these specific refrigerants.
