Whether in restaurants, hotels, schools, hospitals or large-scale commercial catering – in every professional kitchen, powerful and intelligent commercial kitchen appliances are the cornerstones of modern, resource-saving food production. The focus here is on consistent quality, maximum reliability, high efficiency and, last but not least, customisation in order to meet the high demands of everyday kitchen work.
Nowadays, planning and equipping catering and commercial kitchens should not only focus on classic appliances such as combi steamers, convection ovens, kettles, deep fryers and dishwashing technology, but should also take a holistic view of kitchen processes. Networked appliances and digital solutions can simplify processes whilst saving valuable resources such as energy and water. Optimise workflows and reduce stress in the kitchen team, increading employee satisfaction. This helps to retain good kitchen staff and hopefully attract new ones.

Commercial kitchen appliances are appliances used in professional kitchens in the catering industry, i.e. large and commercial kitchens. They differ from domestic appliances in that they are generally much more powerful and can therefore prepare large quantities of food quickly and to a high standard. They are usually made of stainless steel and impress with their robust construction and excellent quality, which are necessary for demanding kitchen operations and a long service life.
The kitchen appliances used in a professional catering kitchen will largely depend on what their functions are and what food they can produce. However, combi steamers in various sizes are now standard in every commercial kitchen. In large production kitchens, these are usually free-standing appliances with up to 20 racks. However, smaller combi steamers are also often found in kitchens of all sizes. Multifunctional appliances such as the iVario that work with contact heat are also commonly found in modern kitchens. What both appliance groups have in common is that they are designed for different cooking applications. This allows a wide variety of dishes to be produced flexibly in a small space. Of course, these types of appliances are also ideal for à la carte restaurants and supermarkets. What's more, modern technology in commercial kitchens also saves energy and water, making kitchens much more sustainable.
A professional commercial kitchen requires a wide variety of connections, depending on its equipment. In addition to the normal power supply, kitchens often require high-voltage currents to operate high-performance appliances. This ensures fast heating times and high heat transfer to the food, guaranteeing consistent results even in larger quantities. It should be noted that high connected load does not necessarily mean high energy consumption. Intelligent appliances ensure optimised use of resources and the best food quality. A modern commercial kitchen also needs water connections, both for cooking and for dishwashing and cleaning technology. Intelligent appliances can also be easily networked, not only to keep track of all appliances at a glance, but also to make work easier and more convenient. Network connections or appropriate WiFi connections in the kitchen are therefore highly recommended if you want to use all the features of the appliances.
Even though commercial kitchens are not necessarily considered pioneers in digitalisation, modern kitchen appliances are often equipped with smart assistants that enable precise monitoring or even control of the appliance fleet. ConnectedCooking is one example of how this can be used to update appliance software, distribute cooking programmes to multiple appliances in different locations or easily document HACCP data.
The equipment in a commercial kitchen depends on the menu and preparation methods. Kitchens using more convenience products need different equipment than those producing everything fresh. Cooking methods - such as cook & hold or cook & chill - and the availability of skilled staff also influence kitchen design. This is where intelligent kitchen technology becomes indispensable. Appliances like the iCombi Pro combi steamer and iVario Pro multifunction unit alert staff when to load, unload, stir, or pour, saving time and space while reducing the need for multiple separate appliances.
Extractor hoods and ventilation systems should match the cooking technology. Modern systems, such as those from RATIONAL, deliver only the heat needed, often allowing for smaller fans and lower investment costs while eliminating the need for additional appliances.
Efficient kitchen planning also requires modern, sustainable dishwashing and refrigeration technology. Layout, space-saving design, and short distances are crucial to smooth operation.
A well-equipped catering kitchen includes commercial cooking technology, refrigeration, dishwashing units, stainless steel furniture, and essential utensils. At its heart, ovens and hob, like the iCombi Pro, should be powerful, high-quality, and energy-efficient.
