  STEAM.MAXI™ UNOX STEAM.Maxi™ technology carries out every type of steaming process, even the most delicate ones starting from a temperature of 35 °C (95 °F). This result is possible thanks to a production of steam that is up to 3 times superior to that obtained with traditional direct injection ovens when using the same amount of water.
• Page 68
  Closed loop system In case of Humidity Measurement parameter set to ON, the timing of the opening of the solenoid valves is proportional to the difference between the humidity value set point, Hsp and the relative humidity value measured, Hm. Therefore, the steam tables are chosen according to this feedback control, figured in Figure 5.
• Page 69
  You can cook whatever you like, with Unox, quality comes as standard. DRY.Maxi™ technology consists of a solenoid actuator fed at 230 V AC connected to the power board. Its function is to extract humidity from the cooking chamber, as shown in Figure 7.
• Page 70
  Closed loop system The timing of the DRY.Maxi™ valve meets the data reported in Table 8. Every time the humidity measurement is greater than 30%, the DRY.Maxi™ setting of the table above is increased by 20%. After this first adjustment, every time the humidity reading is less than 30% the DRY.Maxi™ is reduced by 20%.

  Air.Maxi The UNOX motor is equipped with two turns: one is AIR.Maxi™ technology ensures perfect distribution of the primary and the other is the auxiliary and vice the air and therefore of the heat within the cooking versa on the basis of which the electrical current chamber.

  Speed regulation The fan can spin in four different regular speeds and four pulse speeds. These speeds are equivalent in terms of RPM, but in the pulse mode the fan spins only when the heating element are turned on. Temperature and humidity measurements are the limiting factors for the fan speed as reported in table 13.

Note for the first start: if the speed is set to 1, the fan starts at speed 2 until the cooking table 15 chamber reaches 90˚C (194°F).

  CHEfTOp MINd.Maps The new floor-standing trolley ovens have been launched in April 2019 named as CHEFTOP MIND.Maps™ BIG PLUS. Built on the current MIND.Maps™ line the ovens have improved drastically in terms of design, durability, and performance. This chapter is going to give details on the improvements and modifications. The points that aren’t mentioned should be considered as the same as the MIND.Maps™.

  CHEfTOp MINd.Maps ZErO The new convection ovens were launched in February 2020 and called CHEFTOP MIND.Maps™ ZERO. Built on the current MIND.Maps™ line, the ovens have improved drastically in terms of aesthetics, design, and performance. The chapter below details the improvements and changes made. Zero ovens are designed with the Mind.MapsTM family. Zero ovens are equipped to provide steam, but automatic cleaning cannot be performed because they don’t have washing circuits.
