CASE STUDY: Replacing old Lainox Combi ovens with new Rational iCombi Classic

Scope of Work:

Project Duration: 1 Evening & Night
Installed: February 2023
Type of Project: Commercial Kitchen Oven Replacements


Amidst the cold weather in February 2023, we installed a new range of Combi ovens for Williams Grand Prix. They were struggling with capacity in their current layout but didn’t have the space to increase the cook line. Originally, they were using 2x 10 Grid Lainox Combi ovens which had a capacity of 20 Standard Gastronorm Pans.

The solution was to upgrade the make & models so we installed 1x Rational iCombi Classic 10-2/1 and 1x Rational iCombi Classic 6-2/1; these are wider than the normal combi ovens allowing you to get 2 times the capacity of Gastronorm pans inside. The capacity for the 10-2/1 is therefore 20 pans and in the 6-2/1 you can get 12. This gave Williams Grand Prix a total capacity of 32 Gastronorm pans in their new setup up from a capacity of 20. They’ve gained much more cooking capacity by taking up no extra space in their kitchen.

The installation process

To ensure no downtime in this bustling commercial kitchen, we planned to carry out our work when the kitchen was not in use. We had our engineers go into the kitchen after it was closed and carried out the required work during the evening and night to ensure it was ready to go the next day. The old ovens were disconnected and removed from site for disposal and the new ovens were stacked, installed and commissioned, ready for service the next morning.

As the new combi ovens were stacked the drain connections were lower than the old ovens so we had to use an external combi sump pump to get the wastewater into the drain. We also installed extra water filtration due to the hard water in the area. This items were supplied by European Water Care.
