Convotherm OES Mini - 6 x1/1 GN, Electric
About this oven
The Convotherm Mini packs full combi cooking into a footprint just 515mm wide, small enough for a counter top, a café back bar or a pub kitchen with no room for a full-size oven. It’s built by German combi specialists Convotherm and cooks with convection, steam or a combination of both. You can cook crisp vegetables in bright colours, succulent roasts with crisp crusts and delicate fish together, with no transfer of flavour between them.
It suits small to medium operations: cafés, delis, smaller restaurants, pub kitchens, hotel room service and front-of-house cooking stations. It’s also a good second oven alongside a larger combi for extra capacity at busy times.
What you get
- Three cooking modes: convection, steam and combination cooking, for roasting, baking, steaming, poaching and regenerating
- Injection steam: steam is produced by spraying water directly into the cabinet, so there’s no boiler to descale or maintain
- Compact cabinet: takes 6 x 2/3 GN containers at 20 or 40mm deep, or 4 at 65mm deep, plus 4 plates of 28cm for plated regeneration
- Closed cooking system: Convotherm’s sealed cabinet keeps steam and heat where the food is, for moist results and less shrinkage
- Programmable controls: save your regular dishes so they cook the same way every time
- Small, light and easy to place: 515mm wide and around 45kg, so it fits where other combis won’t
How it compares
The OES mini is the earlier generation of Convotherm’s compact range, which has since moved to the Convotherm 4 mini and the current mini pro. Newer models add features like a larger touchscreen and connectivity, but the OES mini has the same core combi cooking and compact footprint for a fraction of the price. Against the Rational SCC XS, it’s slightly narrower, with injection steam rather than a boiler.
Honest about what it isn’t
A 6 x 2/3 GN cabinet holds about two-thirds of a standard 6-grid, so it’s sized for smaller volumes and isn’t a replacement for a full-size oven in a high-output kitchen. It also uses 2/3 GN containers rather than standard 1/1 trays. It needs a water connection and drainage like any combi.
