Convotherm OGS - 20 x 1/1 GN, Gas
About this oven
The Convotherm OGS 20.10 is a floor-standing, roll-in combi oven for kitchens cooking at real volume: banqueting, hotels, hospitals, schools, contract catering and central production kitchens. It holds 20 x GN 1/1 on a roll-in trolley. You load the trolley away from the oven, wheel it straight in and wheel the whole batch out when it’s done, so hot trays don’t need to be moved one by one.
Convotherm is one of the best-known German combi brands. Its Advanced Closed System cooks in a sealed cabinet that keeps steam and heat where the food is. The result is moist meat, less shrinkage, and different foods cooked side by side with no transfer of flavour.
What you get
- Three cooking modes: steam, convection and combination steam, for roasting, baking, steaming, poaching and regenerating
- Advanced Closed System: Convotherm’s sealed cooking cabinet for moist results, less shrinkage and no flavour transfer between dishes
- Injection steam: steam is produced by spraying water directly into the cabinet, so there’s no boiler to descale or maintain
- Roll-in trolley loading: load a full 20-shelf batch away from the oven, then roll it in and out in one move
- Gas heating: lower running costs than electric on many sites, and a strong choice where three-phase capacity is limited
- 20 x GN 1/1 capacity: large batches for banqueting and mass catering, or plated regeneration with a plate trolley
How it compares
The OGS generation was replaced by the Convotherm 4, which adds a more modern control panel, ConvoClean+ automatic cleaning and connectivity. The OGS has the same core closed-system cooking and roll-in capacity at a fraction of the price of a new 20-grid. Against a Rational 202 or 201, it gives similar volume. The injection steam keeps maintenance simpler than a boiler model.
