Rational Equipment: New & Refurbished from GMSE
Rational is the world's leading manufacturer of combi steamers and multi-purpose cooking systems for professional kitchens. Founded in Germany in 1973, the company has focused exclusively on intelligent thermal food preparation equipment since 1978 — a singular focus that has made Rational the benchmark against which all other combi oven manufacturers are judged. Today, Rational equipment is installed in more than a million professional kitchens worldwide, from independent restaurants and hotel kitchens through to large-scale contract catering facilities and food production operations.GMSE stocks the full Rational range — the iCombi Pro combi oven series across the complete range of sizes, configurations and power supplies, and the iVario Pro multi-purpose cooking centre in all available sizes and specifications. Both ranges represent the current state of the art in their respective categories and are backed by the full Rational manufacturer warranty when purchased new. Finance options are available across the range.In addition to new Rational equipment, GMSE periodically stocks refurbished Rational combi ovens — assessed, overhauled and tested by our accredited engineers before sale, and backed by our standard 12-month parts and labour warranty. Our engineering team can service and support Rational equipment after purchase, whether bought from us or from another supplier.Browse the full Rational range below, or contact our team for guidance on the right model for your kitchen and application.
Rational iCombi Pro Combi Ovens
The Rational iCombi Pro is the most advanced combi oven available — and the model against which the entire combi oven market measures itself. Combining convection, steam and combination cooking modes in a single unit, the iCombi Pro uses Rational's iDensityControl technology to continuously monitor and regulate the cooking climate inside the oven, adjusting temperature, humidity and airflow automatically to deliver consistent results regardless of load size or product variation.
Key features of the iCombi Pro include the iProductionManager, which coordinates up to twelve simultaneous cooking processes in the same oven; a 6-point core temperature probe for precise internal temperature monitoring; and the iCare AutoDose autonomous cleaning system, which manages the cleaning cycle automatically from the integrated solids cleaner. All iCombi Pro models are Energy Star certified.
GMSE stocks the full iCombi Pro range — covering 6, 10 and 20 grid configurations in both 1/1 GN and 2/1 GN sizes, electric and gas, including countertop and floor-standing models with optional stands and trolleys. With 48 models available, there is an iCombi Pro specification for every professional kitchen requirement.
Rational iVario Pro Cooking Centres
The Rational iVario Pro is a multi-purpose cooking centre that replaces multiple pieces of equipment in a single unit — functioning as a boiling pan, bratt pan, fryer, pressure cooker and stock pot simultaneously. Using intelligent sensor technology and precise temperature control, the iVario Pro manages large-batch cooking with the same consistency and precision as the iCombi Pro, making it the natural companion piece to the combi oven in a well-equipped professional kitchen.
The iVario Pro range is available in four sizes — the 2-XS twin pan for smaller operations, the 2-S twin pan for mid-volume kitchens, and the L and XL single-pan models for larger-scale production environments. Models are available with or without pressure cooking and hand shower functions, and with stand options for countertop or floor-standing installation.
The Rational iVario Pro 2-S is a hugely innovative cooking system, designed to replace almost all conventional cooking appliances. Able to boil, griddle and deep fry, the iVario brings productivity, flexibility and simplicity to your kitchen, helping you to boost your efficiency and output.
With its unique heating technology, the Vario Pro offers impressive power and precision. Thanks to its intelligent cooking assistants, which think with you and support you, you achieve outstanding food quality every time, without any monitoring or checking.
The iVario is designed to cook up to 4 times faster, using up to 40 % less energy and a providing huge space gain compared to conventional cooking appliances. This means that an iVario can pay for itself in just a few months. Integrated iVarioBoost energy management system and iCookingSuite intelligence generate high quality cooking results, precisely and quickly.
This 2-S version features full size gastronorm-size 25Ltr pans, providing plenty of capacity for around 100 meals a day. This option includes pressure cooking and a hand shower.

The right size depends on your daily cover count, production volume and the physical dimensions of your kitchen. As a general guide, a 6-grid iCombi Pro is suited to kitchens producing up to around 100 covers per service; a 10-grid covers mid-to-high-volume operations; and a 20-grid is suited to large-scale production kitchens and central production facilities. Within each grid size, the choice of 1/1 GN or 2/1 GN, electric or gas, and countertop or floor-standing depends on your power supply, space and throughput requirements. Our team is happy to advise on the right specification before you commit.
