The Smeg Professional ALFA420H-2 Commercial Convection Oven with Humidification is a premium European-engineered benchtop baking, roasting, and heating appliance designed for Australian cafes, bakeries, restaurants, hotel lounges, bistros, and commercial catering operations. Engineered for high-volume service where space efficiency and baking consistency are paramount, this 4-tray unit accommodates both standard 600x400mm pastry sheets and GN 1/1 Gastronorm pans at a 77mm shelf spacing.
Featuring dual contra-rotating fans with timed directional reversal and direct water injection humidification, the ALFA420H-2 delivers exceptional heat distribution and moisture control for crusty breads, pastries, and succulent meats. Constructed with a food-grade Ever Clean enamel interior cavity, a tilting double-glazed door with removable inner glass, and dual LED illumination, this commercial unit operates on a standard 3-phase 400V power supply (6.9kW) and is backed by Smeg's 24-month commercial warranty.
Choosing the Smeg Professional ALFA420H-2 Oven equips commercial kitchens with a versatile, high-precision, and durable baking system built for daily commercial performance.
Key reasons commercial operators specify the Smeg ALFA420H-2 include:
Dual Contra-Rotating Fan System: Two heavy-duty fans with automatic timed direction reversal ensure uniform airflow and even browning across all four tray levels without manual rotation.
Dual 600x400mm & GN 1/1 Tray Versatility: Chrome tray support frames accept four 600x400mm bakery sheets or GN 1/1 Gastronorm pans set at an optimal 77mm shelf pitch.
Direct Humidification Control: Manual water injection system sprays moisture directly into the cooking chamber for crisp bread crust formation, delicate pastry rise, and moist roasts.
Hygienic Ever Clean Enamel Cavity: Smooth, non-porous Ever Clean enamel lining resists grease bake-on, simplifying end-of-shift sanitisation.
Tilting Double-Glazed Door: Heavy-duty tilting door construction retains chamber heat while keeping exterior touch temperatures safe, featuring a removable inner glass panel for easy cleaning.
Simple Electromechanical Controls: Intuitive mechanical dials allow staff to easily select cooking temperatures (50°C to 270°C) and set timer durations (1–60 minutes or endless continuous mode).
High-Visibility LED Interior Lighting: Two bright 40W internal LED lamps illuminate all four rack levels clearly during service.
Robust 3-Phase Commercial Power: Operates on 400V 3N~ power with a 6.9kW loading for fast preheating and rapid thermal recovery between loads.

Delivery & Freight Notice: Commercial heavy equipment requires dedicated freight handling. Please contact our friendly commercial sales team for a custom freight quote if delivery is required for a residential or non-commercial address.
Setup & Preheating: Turn the temperature control dial to your desired setpoint (up to 270°C) and set the timer duration or endless mode. Allow the dual contra-rotating fans to bring the chamber to working temperature before loading your trays.
Baking & Humidification: Load your 600x400mm trays or GN 1/1 pans onto the chrome side runners. Engage manual water injection during the initial phase of baking to introduce surface moisture for artisan breads or roasts.
End-of-Shift Sanitisation: Allow the cavity to cool completely. Unlatch and remove the inner glass pane from the tilting door to clean between glass layers. Wipe down the smooth Ever Clean enamel walls with a soft, non-abrasive damp cloth and mild food-safe cleaner.
