Units of this type are widely used in meat processing plants, butcher shops, slaughterhouses, cold storage warehouses, breweries, and the dairy industry to supply refrigeration and freezer rooms, quick-cooling tunnels, or technological lines for cooling liquids. The heart of the system is the legendary, 4-cylinder semi-hermetic Bitzer compressor, characterized by its exceptional performance, high energy efficiency (even under partial load), and unparalleled mechanical durability. The compressor is integrated with a horizontal Bitzer F 400 H liquid tank with a capacity of 39 liters (pressure resistance up to 28 bar), which acts as a buffer for the liquid refrigerant, stabilizing the operation of the entire system under varying ambient temperatures and evaporator thermal loads. The offered set also includes additional extensive supporting infrastructure: a vertical medium buffer tank (dimensions: Ø 1100 x 2600 mm), a high-performance Grundfos circulation pump, and a control switchboard with complete electrical equipment and protection devices (pressure switches, contactors). Thanks to this, the unit can be used directly as a complete, self-contained refrigeration machine room.

This type of system is designed to power low-temperature installations – freezers, freezing tunnels, and advanced refrigeration systems in food processing plants (meat, fish, bakery). Gsdoy Ub A Njpfx Aqiebr The design based on three identical units allows for very flexible, three-stage cooling capacity management (in steps of 33%). The system automatically activates the appropriate number of compressors depending on the actual thermal load, which optimizes energy consumption and extends the service life of the components. The entire unit is mounted on a compact support frame, which facilitates installation. Key features: - Reliable Bitzer two-stage compressors: The two-stage compressor series is specifically designed for deep freezing. It ensures stable operation at very low evaporation temperatures and is characterized by a high energy efficiency ratio. - Safety and automation of the Linde frame: The industrial design of the frame integrates a common suction and discharge manifold, an advanced oil equalization and separation system, and the necessary control and measuring equipment (protective pressure switches), which effectively protects the system from failures. - Industrial protection class (IP 54): Hermetic electrical boxes and the compressor design protect the system from moisture and dust, allowing for safe operation in harsh machine room conditions. - Application versatility: The unit is factory-designed to operate with R22 refrigerant. Due to the presence of compressors with the "Y" designation (filled with ester oil), the system can be successfully adapted to work with modern, environmentally friendly alternatives from the HFC group (e.g., R448A / R449A / R404A / R507) after a standard verification of seals and automation settings.
