PTT 500-1000-1500-2000

  • Even tempering of products in containers on pallets
  • Rapid acceleration of chilling or warming processes
  • Operating with circulating air; no separate chilling or warming source necessary
  • Example: Tempering from approx. -18 to -2 °C within 10 to 14 h with minimal loss of juice (at room temperature of approx. 4 to 8 °C)


  • Pallets with up to 14 layers of E1 crates or up to 9 layers of E2 crates are moved into the tunnel and a temperature sensor is placed in the meat. Depending on the version, 1 to 4 pallets can be positioned one behind the other.
  • The upper awning is lowered and the tempering process can begin.
  • A strong fan draws air through all crates. This airflow causes the upper and lateral awnings to attach to the crates thereby insulating the hollow space between the crate and the awning. As a result, the temperature at the outside is equal to the temperature at the centre of the pallets.
  • Due to the uniform airflow through all layers on the pallet, the tempering is consistent and precise for all pallets.
  • The unit works only with ambient air (no additional cooling or heating element is required), meaning the unit can be used for defrosting or rapid cooling or freezing purposes, depending on the location of use. A controller is used to set the desired temperature.


  • Rapid tempering in E1/E2 euro containers on pallets
  • Even temperature in all containers
  • Ideal processing temperature with no drip loss
  • Energy recovery
