Rational Product Groups

iCombi Pro Combi Ovens

iCombi Pro is Rational's combi oven series equipped with intelligent cooking features. The electric model with 10 x 1/1 GN capacity is suitable for daily production of 80 to 150 meals. The 6-point intelligent core temperature probe measures the internal temperature of the product at different points, helping the cooking process finish at exactly the right moment.

Dynamic air circulation and a greater number of fans ensure more balanced energy distribution in the cooking cabinet. The cooking cabinet temperature can reach up to 300 °C. A fresh steam generator, LED lighting with rack signaling, a hand shower, a triple-glass door and Wi-Fi connectivity without an external antenna are among its key features. The series includes 6, 10 and 20 tray electric and gas models in GN 1/1 and GN 2/1 sizes. All models are listed in the electric combi ovens and gas combi ovens categories.

iCombi Classic Combi Ovens

iCombi Classic is a combi oven series focused on manual control for chefs who want to set cooking parameters themselves. Hot air and steam can be used individually, in sequence or in combination. According to the product page, the oven performs most of the cooking methods used in professional kitchens in compliance with DIN 18866.

Its ability to replace many conventional cooking appliances in an area of less than 1 m² makes iCombi Classic a suitable option for kitchens with limited space. The electric model with 10 x 1/1 GN capacity has 18 kW of convection power and 18 kW of steam power. The series includes 6, 10 and 20 tray electric and gas models.

High-Capacity Floor Models

In hotel, hospital and institutional catering kitchens, hundreds of portions may need to be prepared at once. Rational's 20-tray floor models are designed for this need. The iCombi Pro 20 x 2/1 GN model in the series is among Rational's highest-capacity ovens at Mutbex.

In floor models, trays can be loaded into the oven all at once with a mobile rack trolley. This structure allows plates to be heated directly in the oven during banquet service and taken out ready to serve. Electric and gas models with 20 x 1/1 GN and 20 x 2/1 GN capacities are offered in the iCombi Pro and iCombi Classic series.

SCC XS Compact Combi Oven

For businesses with limited space such as cafes, bars and small restaurants, the Rational SCC XS combi oven offers a compact solution with a capacity of 6 GN 2/3 trays. The oven brings combi cooking features together in a size that can be placed on a countertop.

It can be used for tasks such as reheating pre-cooked products and preparing sandwiches, vegetables and small portions of meat. For basic information on using a combi oven, you can read our article What Is a Convection Oven.

Chicken and Lamb Roasting Accessories

With special accessories, Rational combi ovens are also used to cook products such as whole chickens, ducks and lambs. The H8 chicken roasting rack holds chickens vertically in the oven and has a capacity of 8 chickens. Cooking chickens in an upright position allows fat to drip off, helping every surface brown evenly.

According to the product page, these racks allow 24 chickens to be cooked at the same time in 10 x 1/1 GN ovens and 96 chickens in 20 x 2/1 GN ovens. H4, H6 and H10 chicken racks and the E8 duck rack are also part of the series. For preparing whole lamb and kid, the Model 202 lamb roasting spit can carry up to 30 kg. All accessories are listed in the Rational oven spare parts category.

Cooking Trays and Molds

Suitable cooking trays are among the most important elements that expand the range of uses of a combi oven. The Rational combi grill tray can create grill marks even on frozen products. The grill and pizza tray in the series is used for cooking meat, vegetables and pizza.

The Teflon-coated egg mold allows 8 omelets or eggs to be prepared at the same time during breakfast service. Fry baskets are designed for frying frozen products without oil. A potato baker, muffin and timbale molds and GN trays of different depths are also available in the series. Other products are listed in the oven accessories category.

Banquet Systems and Mobile Plate Racks

Serving hundreds of plates hot at the same time at weddings and events requires separate planning. Rational mobile plate racks allow pre-plated dishes to be placed in the oven all at once and heated together. The 60-plate model is designed for plates up to 31 cm in diameter and moves on quiet, hygienic casters.

Models with 34, 42 and 52 plate capacities and a 26-plate banquet system are also part of the series. The 20-shelf mobile tray rack allows trays to be loaded into the oven all at once. The models are listed in the multi-tier plate trolleys and banquet trolleys categories.

Cleaning and Care Tablets

Combi ovens require regular cleaning and maintenance to maintain their performance. Rational ovens have an automatic cleaning program, and the brand's own tablets are used in these programs. The Active Green cleaner tablet in the series dissolves grease and burnt-on residues on the interior surfaces of iCombi Pro and iCombi Classic ovens with its phosphate-free and phosphorus-free formula.

Care tablets help clean limescale and residues that form on the interior surfaces of the appliance. Detergent tablets are also offered for previous generation ovens. We explained in detail which tablet is used in which oven in our video. All products are listed in the oven cleaning chemicals category.

Choosing the Right Tablet

Rational cleaning tablets are not independent of the oven generation. The tablet used must be suitable for the oven model and its cleaning system. Using the wrong tablet can reduce cleaning performance and increase the maintenance needs of the appliance.

When choosing tablets, the oven model, intensity of use and degree of soiling should be taken into account. Since the tablets are offered in buckets, stock can be planned according to the frequency of use. Details on the subject are covered in our article Rational Oven Cleaning Tablets.

How Rational Products Contribute to Your Business

Choosing Rational by Business Type

What to Consider When Choosing a Rational Combi Oven

The first step is determining the daily number of portions. While 10 x 1/1 GN models are suitable for 80 to 150 meals per day, businesses with higher production may prefer 20-tray floor models. When choosing the tray size, the size of the gastronorm containers used in the kitchen should also be taken into account.

For electric models, a three-phase electrical connection and a suitable fuse rating should be checked, and for gas models, the gas infrastructure. In combi ovens that produce steam, water hardness directly affects the service life of the appliance. You can check the water hardness in your area on the Water Hardness Map. Details are covered in our article Türkiye Water Hardness Guide for Commercial Kitchens.

Equipment Used with Rational

Together with combi ovens, gastronorm containers are used for preparing, cooking and storing products. Suitable hoods are preferred for extracting the steam coming out of the oven. For other kitchen equipment, Öztiryakiler products can be considered. You can benefit from our articles How to Clean a Commercial Oven for oven maintenance and Why Commercial Equipment Is Essential in Hotel Kitchens for setting up a hotel kitchen.
