Product catalog summary

Applications
The AlfaBlast blast freezer is a fan air cooler with a horizontal airflow direction, used in fast-freezing units. It is ideal for rapid freezing in confined spaces and is applicable in industries such as meat, poultry, fish, bakery, dairy, ice cream production, and ready-to-serve meals where quick food preservation is necessary.

Design Features and Benefits
AlfaBlast is compatible with refrigerants R404A, R507A, and NH3. It features a lower refrigerant charge compared to similar products, benefiting both budget and environment. The design also supports low electricity consumption and offers smart solutions for easy installation and maintenance.

Standard Configuration
The standard configuration includes a galvanized steel casing, aluminum drip tray, air static pressure of 80 Pa (500 series) and 100 Pa (630 series), a static defrost system, lateral cover panels, and adjustable legs for customization.

Optional Features
Options include casing in stainless steel or aluminum, special fans for high static pressure (150 Pa), various defrost systems (water, electric, hot gas), and different coil protections (cataphoresis, epoxy, pre-coated fins).

Performance and Capacity
AlfaBlast offers a capacity range for DX with R404A from 12 to 91 kW (SC3 condition) and for pump with NH3 from 16 to 117 kW. Test pressures are 34 bar for direct expansion at temperatures -45° to +130°C and 31 bar at -50° to +100°C.

Casing and Coil Specifications
The casing is available in galvanized steel (standard), stainless steel, or aluminum (optional). It features removable lateral panels and an aluminum drip tray. Coil specifications include fin spacing of 7, 10, or 12 mm, with fins made of aluminum and piping of copper or stainless steel.

Fans and Noise Levels
Fans have diameters of 500 or 630 mm, with a motor fan type of 3-phase 400V 50/60 Hz. Air static pressure is 80 Pa for 500 mm fans and 100 Pa for 630 mm fans, with 150 Pa available on request. The noise pressure level is a maximum of 84 dB(A) at 10 meters.

Defrost Systems and Coil Protection
Defrost systems include static (standard), electric, water, hot gas, and combinations in the drip tray. Optional coil protection includes cataphoresis, epoxy painting, and pre-coated fins.
