About this oven

The RATIONAL® CombiMaster® Plus (CMP) is a manual-control combi oven for chefs who want full control over the cooking and none of the work around it. Steam, convection and combination cooking in a single cabinet: roast, bake, steam, grill, poach and regenerate without switching equipment or finding floor space for a second appliance.

You stay in charge of the cooking. The oven handles everything else: it measures its own humidity, stores your recipes, and cleans itself at the end of service. The only thing it needs is a CTU (Water Treatment unit) to prevent scale in areas with hard water. 

What you get:

• Three cooking modes - steam from 30–130°C, hot air from 30–300°C, combination from 30–300°C 
• ClimaPlus® - the oven measures cabinet humidity and regulates it across five stages, rather than simply running a setting 
• Five programmable air speeds - low and intermittent for soufflés, custards and delicate fish; full power for loaded roasting racks 
• Core temperature probe - cook to a precise internal finish, particularly on overnight and large-joint work 
• Recipe storage - build multi-step programmes of up to six steps so a dish runs identically whoever's on the section, and transfer programmes by USB 
• Finishing® mode - hold and finish plated service, buffets and banqueting covers without drying them out 
• CleanJet® - unlike the models with fully autonomous tablet care systems, the CMP requires you to manually spray liquid cleaner or place specific cleaning tabs into the cooking cabinet. It includes semi-automated cleaning cycles that control soaking, washing, and rinsing durations automatically once started
• Built for real kitchens - integrated hand shower with automatic retraction, centrifugal grease extraction with no filter to clean, rapid cool-down, HACCP logging, LAN connectivity, and a double-glazed heat-reflecting door
• Stainless steel throughout, with a seamless cabinet and rounded corners for fast wipe-downs at the end of service

Honest about what it isn't

The CMP has no automatic cooking programmes; it won't decide a roasting profile for you the way a SelfCookingCenter will. That's the point. It also means fewer electronics than an automated combi, so there's less to fail over a long service life.

Refurbished properly, not just cleaned up

At CaterCombi, every unit is fully refurbished by manufacturer-trained engineers, including our own 57-point inspection, deep clean, descaling and component testing to ensure dependable day-one performance. Robust German engineering, built to run for years; our job is to make sure yours starts that clock again from day one.
