Optimal design made real
Alfa Arctigo ID
Alfa Arctigo ID
Designed for flexibility and optimal operation, Alfa Arctigo ID meets the demanding needs of cold storage, freezing and technical infrastructure with high efficiency and long-term durability.
Consultant
Alfa Arctigo ID models provide Eurovent-certified performance (for HFC/CO2 DX models) and versatile dual-discharge configurations for precise industrial cold room designs from +20 °C to -40 °C across HFC, ammonia, CO₂ and brine. Comprehensive documentation – including drawings, wiring diagrams and selection software – supports accurate calculations. Multiple fin spacings (4-12 mm), defrost options, fan sizes and coil configurations enable tailored flexibility for any industrial application.
System Integrator
Alfa Arctigo ID’s modular design with 1-5 fans (450-630 mm AC/EC) simplifies integration into diverse industrial refrigeration systems. Low-profile dual discharge footprint with customizable connections (top connections for brine units) fit tight ceiling spaces while maintaining uniform airflow coverage. Pre-assembled options like insulated drain trays and hinged access reduce onsite commissioning time across all refrigerant types.
General Contractor
Alfa Arctigo ID offers fast ceiling installation with pre-tested units delivered in mounting position on wooden beams. Heavy-duty pre-galvanized RAL9003 casing withstands industrial environments; low-profile design maximizes cold room height. Hinged side panels, driptray and forklift-ready packaging minimize onsite work and ensure quick commissioning.
