Houno Invoq 20 Grid 1/1 GN Electric Combi Oven

The Houno Invoq 20-grid electric combi oven is a large-format unit built for professional kitchens that need to move serious volume through service with reliable, consistent results. It combines steam, convection, and combination cooking modes with a suite of automated controls that reduce the level of hands-on supervision required during busy periods — without removing control from the operator.

At 20-grid capacity, this oven is designed for operations cooking at scale: banqueting facilities, hospital catering, hotel kitchens running high covers, central production units, and contract catering environments. The Climate Control system monitors and adjusts heat and humidity continuously throughout the cook cycle, which helps maintain consistent results across a full load even as moisture levels shift between dishes. Recovery between back-to-back loads is a genuine operational consideration at this volume, and the combination of element output and climate management keeps that recovery time practical during sustained service.

The front-mounted touchscreen and drag-and-drop Menu Planner allow multiple cooking programmes to run concurrently — useful when a kitchen is producing different dishes across different sections at the same time. SmartChef and Cook Time Correction handle adjustments that would otherwise require a chef to monitor and intervene, helping to reduce inconsistency and food waste during high-pressure periods.

• Simultaneous multi-programme cooking reduces bottlenecks at peak service
• Automated climate and time correction supports consistent results from less experienced staff
• Built-in Care Cycle cleans the cavity at the end of service with minimal effort
• Robust stainless steel construction withstands the demands of daily commercial use
• Intuitive touchscreen interface reduces training time when onboarding new kitchen staff

Installation requires careful advance planning. The unit draws significant three-phase power, so your electrical infrastructure will need to be assessed before ordering. At 277kg, access routes, floor loading, and final positioning all need to be considered well ahead of delivery. Ventilation is essential — the oven must sit beneath a correctly specified extraction canopy. A water supply and drain connection are also required for both cooking functions and the internal wash cycle. These are not unusual requirements at this scale, but they do need to be confirmed before the unit arrives on site.

This oven is well suited to high-volume operations where consistency across large-batch cooking is a priority and where a degree of cooking automation makes practical sense. For lower-throughput kitchens or smaller service volumes, a reduced grid count would be more appropriate both operationally and economically. For sites running multiple service periods or very high covers, it is worth considering whether a single large unit or a pair of smaller units better fits your workflow and resilience requirements.

Given the scale of investment and the installation requirements involved, it is worth talking through the details before committing. We are happy to discuss your kitchen layout, power supply, service volumes, and workflow to make sure this specification is the right fit.
