Concrete industry

Air is sucked in by several ventilators from a softening room and pressurized in a pressure room. An air concentrator nozzle presses the pressurized air back into the room. This way, the air flow reaches the other side of the room. This perfectly dimensioned air flow ensures a homogeneous temperature and humidity in the room. A heat exchanger is placed at the suction side away from the ventilators and adds the necessary hardening heat to the room. Damp is added when the air leaves the air concentrator nozzle.

Air curtains

In many cases, a climate room is not closed off for one 100%. This is because there are trucks continuously driving in and out to bring and take concrete products. To shield the acclimatized zone from the conditions outside, companies often choose a solution which involves an air curtain. A large quantity of conditioned indoor air is blown from one side of the opening to the other side. The conditions indoor and outside are, thus, separated by an air barrier.

The achieved advantages of this new concept:

  • Constant quality.
  • No colour differences.
  • Less scale.
  • Using cheaper kinds of cement.
  • Quicker finishing, such as centrifuging, radiating.
  • Considerable longer life span of the expensive production planks.
  • Longer life span of the metal hardening racks.
  • No overpressure, as with steam, thus no mist forming.
  • Less influenced by the weather during the changing of seasons.
  • Little or no maintenance.
  • Very low energy costs.
