Industrial, central multi-compressor unit manufactured by Arco based on reliable, semi-hermetic reciprocating compressors from the renowned German brand Bitzer. The unit is designed to power extensive refrigeration systems (both medium- and low-temperature) in food processing plants, meat processing facilities, cold storage warehouses, and distribution centers.

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.

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).
