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). 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.

The system, based on two powerful compressors with a total volumetric capacity exceeding 300 m³/h, allows for flexible management of cooling power depending on the current thermal load of the system. The design on a common, rigid frame significantly facilitates installation in the machine room and ongoing maintenance. Holhcey Uay Hocqlenu Key features: - Bitzer reliability: The use of semi-hermetic reciprocating compressors guarantees the highest energy efficiency, long service life, and easy access to spare parts and service. - High flexibility and efficiency: Two independent performance stages allow for smooth or stepped adjustment of the unit's operation, which generates significant electricity savings under variable temperature conditions in production. - Industrial frame construction: Arco's design integrates the necessary safety and automation elements (pressure switches, suction and discharge manifolds, oil separation systems), which ensures stable operation and protects the compressors from liquid hammer. - Versatility: The unit is factory-prepared to operate with the popular and efficient refrigerant R404A (or its modern, low-GWP alternatives after oil verification).
