Direct steaming chambers

tip PAR-D

In direct steaming chambers, steam from an external source- steam boiler, is introduced by a perforated stainless steel tubing (steam distributor) directly into the steaming chamber. The steam distributor can be installed above ground or submerged in a water channel. The steam from the boiler condenses and is irretrievably lost during the steaming process. The steaming process in this model of steaming chamber is simple, but with a higher consumption of water and energy for steaming than in indirect steaming chambers.


The steaming process is conducted automatically, and the steaming regimes are based on the requirements of users, experience and cooperation with the profession.


  • Steaming all types of freshly cut wood (max 3 days)
  • Steam capacity: from 15-50 m3 net per cycle
  • Working medium: wet steam, pressure 0,5 bar
  • Standard steam room width: 5/6/7 m
  • Standard steam room depth: 3/4/5 m
  • Stacking height: 3.5 / 4.1 m
  • Steaming chambers can be constructed according to the customer’s request.
  • Steaming process guided automatically (PD-01 controller). Each steaming chamber has its own controller
  • Remote monitoring and control on a PC using Nigos Parionica software, via the RS485 standard


  • The complete construction of solid aluminum profiles enables high resistance to the roof load (up to 250 kg / m2 of snow) and resistance to wind of 150 km / h
  • Chamber walls are formed of aluminum cassettes AlMg3, connected with stainless steel screws, silicone of high temperature and acid resistance, filled with hard pressed wool 10 cm thick. External sheathing made of sinusoidal sheets with internal ventilation channels
  • Steam distribution system is made entirely of stainless steel (inox)
  • Self control dumper made of aluminum, allows the pressure to be maintained above 0.2 bar
  • Two probes are used to measure temperature in the steaming chamber. Conducting the steaming process by the average temperature value
  • Possibility of installing equipment and doors in the customer’s masonry building
