Industrial central multi-compressor refrigeration package (so-called compressor pack) built by the German conglomerate Linde, based on three two-stage, semi-hermetic piston compressors by Bitzer from the S4G series. These systems are dedicated for supplying low-temperature installations – cold stores, freezing tunnels, and advanced refrigeration systems in food processing plants (meat, fish, bakery).

The design based on three identical units enables highly flexible, three-stage refrigeration capacity management (in 33% increments). The system automatically activates the required number of compressors depending on the actual thermal load, optimizing electricity consumption and extending component service life. The entire assembly is mounted on a compact support frame, simplifying installation.

Key Features:
- Reliable Bitzer Two-Stage Compressors: The two-stage series is specially designed for deep-freezing applications. Ensures stable operation at very low evaporation temperatures and features a high energy efficiency ratio.

- Linde Frame Safety and Automation: Industrial-grade frame integrates common suction and discharge manifolds, an advanced oil equalization and separation system, and all necessary monitoring and control instrumentation (protective pressure switches), effectively safeguarding the unit against failures.

- Industrial Protection Rating (IP 54): Hermetically sealed electrical junction boxes and compressor construction protect the unit against moisture and dust, enabling safe operation in demanding plant room environments.

- Application Versatility: The package is factory-adapted for use with R22 refrigerant. Due to the compressors labeled with ''Y'' (filled with ester oil), the system can be successfully retrofitted for operation with modern, eco-friendly HFC alternatives (such as R448A / R449A / R404A / R507) following standard seal and automation adjustments.
