Expert 42 Vacuum packing machines

Expert 42 – Chamber Vacuum Sealer

Expert 42 is part of Besser Vacuum's Expert Line of chamber vacuum sealers — a step up from the Fusion Line in technological sophistication, offering more programmes, finer process control, and a broader set of professional-grade options. Powerful, technologically advanced, easy to use, and durable, it's engineered with technical solutions built for long-term reliability and simplified maintenance.

Key highlights

• Automatic operation – precise control and ease of use in professional environments.
• Professional use – compact yet built specifically for professional-grade demands, easy to use and store.
• LCD display in 5 languages – an intuitive multilingual interface for precise, immediate control over every stage of the process; vacuum time and sealing time are adjusted via dedicated controls, with an integrated vacuum gauge for optimal monitoring.
• 49 customisable programmes – vacuum and sealing parameters can be preset and saved for maximum flexibility, including dedicated Soft Vacuum settings: intermittent vacuum cycles that treat the product gently, preventing boiling and ingredient separation, while accelerating marination as liquids penetrate the fibres faster at room temperature.
• Vacuum sensor (included) – lets you manually adjust the desired vacuum percentage via an electronic sensor, for more precise control over the preservation cycle.
• Marinating function (included) – supports safe, efficient marination directly within the vacuum cycle.
• GN trays vacuum setup (included) – direct vacuum-sealing in Gastronorm trays for more practical handling.
• Extra vacuum, fast – professional oil-lubricated Busch® pumps (20 m³/h, with 25 m³/h available) reach maximum vacuum in as little as 22 seconds, with gas ballast to prevent air condensation inside the pump and reduce wear.
• Self-diagnostics – continuously monitors the machine's operation for consistent performance and reliability.

Design and durability

Body and components are made from corrosion-resistant AISI 304 stainless steel, with a highly durable transparent polycarbonate lid (minimum 1.5 cm thick) and multidirectional wheels for easy handling and transport. The inner chamber is pressed and rounded from a single piece of AISI 304 steel, with no joints or welds on the walls, simplifying cleaning and extending durability. A dedicated maintenance programme runs 10 consecutive vacuum cycles to break down residues inside the pump and improve oil flow, reducing energy consumption and extending the pump's service life while keeping it automatically clean.

Customisation options

• Second sealing bar – seals multiple bags in a single cycle, optimising processing time and productivity.
• Trim cutting bar – automatically trims excess bag material after sealing, for a cleaner, more professional finish and less waste.
• Double sealing bar – two parallel sealing lines for a stronger, more reliable closure, ideal for intensive use and for foods containing liquids.
• Gas flush (MAP) – injects a protective gas mixture to extend the shelf life of fresh, delicate, or highly perishable products.
• Inclined tray for liquids – prevents liquids or moisture from being drawn into the oil-bath pump, protecting performance and extending the machine's life.
• Printer with USB port – prints packaging details (product name, date/time, expiry, programme used, ingredients) directly onto the pack for instant traceability.
• Soft Air – an external knob adjusts the intensity of air re-entry into the chamber, reducing compression on delicate or fragile products.
• Wi-Fi Industry 4.0 module – available for connected, data-driven production environments.

Compatible accessories

• Embossed Bags and Rolls – transparent, available in multiple weights and sizes, suitable for storage and cooking, including high-performance and compostable variants.

What it's for

Expert 42 is built for professional kitchens and food businesses that need extensive programme flexibility, precise vacuum and sealing control, and the option to scale up with accessories like double sealing, MAP, or traceability printing — including liquid products, which only chamber machines like this one can vacuum-seal directly in bags.
