Houno Invoq 20 Grid 1/1 GN Electric Combi Oven

The Houno Invoq 20-grid electric combi oven is a large-capacity unit designed for professional kitchens that need to move serious volume through service, consistently and with a reduced level of hands-on supervision. Running on three-phase power, it combines steam, convection, and combination cooking modes with a suite of automated functions that take some of the burden off kitchen staff during busy periods.

At 20 grid capacity, this oven suits operations producing at scale — banqueting, central production kitchens, hospital catering, large hotel operations, and contract catering environments where throughput and consistency across multiple trays matter. The Climate Control system regulates heat and humidity continuously during cooking, which helps maintain consistent results across a full load even as moisture levels shift. Recovery between loads is a practical consideration at this volume, and the combination of element output and climate management keeps that manageable during back-to-back service.

The front-mounted touchscreen and drag-and-drop Menu Planner allow multiple cooking programmes to run simultaneously, which is genuinely useful when a kitchen is running different dishes across different sections. SmartChef and Cook Time Correction automate adjustments that would otherwise require a chef to monitor and intervene — reducing the margin for inconsistency and food waste without removing control from the operator.

• Simultaneous multi-programme cooking reduces bottlenecks at peak service
• Automated climate and time correction supports less experienced staff
• Built-in Care Cycle cleans the cavity at the touch of a button post-service
• Robust stainless steel construction holds up to daily commercial kitchen use
• Intuitive touchscreen interface shortens training time for new staff

Installation at this scale requires careful planning. The unit draws 38.2kW on three-phase supply, so your electrical infrastructure will need to be assessed before ordering. At 277kg, access routes, floor loading, and positioning should be considered well in advance. Ventilation provision is also essential — this oven will need to sit under a correctly specified extraction canopy. A water supply and drain connection will be required for both cooking and the internal wash cycle.

This oven is best suited to high-volume operations where consistency across large batch cooking is a priority and where a degree of cooking automation makes operational sense. For smaller kitchens or lower-throughput services, a smaller grid count would be more appropriate both practically and economically. For sites running multiple service periods or extremely high covers, it is worth discussing whether a single large unit or multiple smaller units better suits your workflow.

Given the scale of investment and the installation requirements involved, it is worth having a conversation with us before placing an order — we are happy to talk through your kitchen's layout, power supply, and service volumes to make sure this is the right specification for you.
