What saves your money?
Humidity control inside the cooking chamber is very important for high quality cooking in a combi oven. In the top model line, Retigo Blue Vision, humidity can be set in percent units. It’s not only the steam generation technology itself that is essential, but also the speed and method for extracting the excessive humidity from the combi oven. Control and regulation of humidity both influence electricity consumption.
The airflow in the combi oven makes it possible to prepare several different dishes at once without odours being transferred between them. This applies to dishes prepared in the same mode and at similar temperatures. It lets you bake a bundt cake and fish at the same time. This saves both electricity and the cooking time.
Unique design of the auto-reversing fan, which achieves high performance despite fewer blades. With this, we have improved the evenness of cooking results up to 30% over the previous model. A gap at the back of the fan and the conical shape of the tube create a negative pressure that helps draw fresh air into the combi oven faster.
The fan design also has a positive impact on electrical consumption (fewer blades = less weight, lower energy consumption).
What saves your money?
Incoming water is preheated in a specially designed heat exchanger surrounding the chimney, absorbing some of the heat from the waste steam and condensate. If the combi oven is cooking at high temperatures, preheated water may even exceed 90°C. Generating further necessary steam is therefore much faster and uses less energy.
Because a significant portion of the waste heat is captured in the heat exchanger, the waste water often doesn't need to be cooled. It is cooled to the required temperature standards by injecting a minimum of cold water into the waste tank. Thanks to this, Retigo combi ovens consume very little water. It doesn't consume any at all when preparing food in hot air mode. The built-in heat exchanger presents a premium solution that saves both water and energy.
Water is heated directly by the heating elements right in the boiler tank. This also uses the heat exchanger, which saves electricity and water.
The boiler solution even has an injection system. Thus, even if the boiler unexpectedly fails, the Retigo combi oven doesn't stop cooking. It informs you of a problem with the boiler and automatically switches to direct injection system. No break downs in the kitchen, no stress, keep going.
We take cold water and reduce the flow via the pressure regulator, we then push this water into a heat exchanger which wraps around the exhaust tube and preheats our water, the waste heat is heating the water and by the time it gets to the oven chamber the water is already around 80°C to 85°C. It is then forced into the center of the fan wheel into the spritzer up which then evaporates it into steam. This reduces energy usage hugely and prevents shocking our heating elements which prolongs their life time. It also has huge energy advantages because our system does not spray cold water directly onto the element, our system preheats the water thus using much less energy to create the steam.
Another advantage of boiler-less is that there is less to go wrong, minimal scale build up in the heat exchanger system. No elements to replace, less labour costs.

Insulation, triple door glass and flap valve
High-quality heat insulation 50 mm thick and triple door glass with a special reflective layer eliminate heat loss and lower your energy cost.
The unique triple-glazed* door solution reduces surface temperature and eliminates the risk of burns. A special layer applied to one of the pans repels heat back into the cooking chamber and helps significantly reduce heat escape and electrical consumption.
*Does not apply to size 623
A fast-opening and -closing valve helps precisely regulate humidity in the combi oven’s chamber. A special suction shape and unique fan design very quickly remove excess moisture with minimal temperature loss in the chamber, which saves considerably on energy. Compared to the previous combi oven model, suction efficiency has improved up to 86,5%. This means that in a Retigo combi oven it is easy to cook meat that is juicy on the inside and pleasantly crunchy on the outside. The technology used removes moisture with less heat escape than with most other solutions that increase the diameter of the exhaust tubes.

Low temperature baking
Overnight cooking pays of
Low-temperature cooking (at night) has indisputable advantages in saving time and energy, while achieving much higher yield and better quality of roasted meat. You have the certainty of perfectly prepared meat in the morning, and thanks to lower volume loss, you get a few extra portions. This saves money in electricity and the cook's time. The cooking process can even be observed remotely through the Retigo Combionline® system.
| Overnight cooking | Volume loss as % | |||
|---|---|---|---|---|
| B611i | Number of hours | Consumption [kWh] | Beef | Pork |
| Energy used during ordinary cooking at 160°C | 2 | 10 | -50% | -30% |
| Energy savings at 80°C in combination mode | 12 | 6 | -40% | -10% |
| Savings | - | 4 | 10% | 20% |
The following graph shows HACCP data for overnight cooking: 17,5 hours, 6,64 kW of electricity. Measured on a Retigo Blue Vision 611i combi oven. Such low consumption is achieved by the quality cooking chamber insulation and the special triple-glazed door design. Throughout the cooking process, the combi oven actually only heats for about 2 hours.
ENERGY STAR
Retigo is a proud partner of the Energy Star programme for saving energy and protecting the environment. Despite the new, stricter limits required for certification, Retigo combi ovens exceed these values and achieve outstanding energy efficiency.
