DAF1, DAF2, CrossFlow alternating air flow system

The innovative alternating airflow system consists in regular changing the airflow direction through the products from top to bottom and bottom to top. As a result, the risk of over-drying the surface of the product is greatly reduced, the most even possible processing of the products throughout the chamber is ensured, and the entire drying process is accelerated. The air-conditioned chamber equipped with an alternating flow system will also better cope with the risk of growth of undesirable microorganisms on the surface of products.

1. DAF 1(Dual Air Flow system 1)

- vertical phase - the air enters the chamber through the vertically positioned nozzles, passes through the product trolleys and is sucked out through the ducts located above the trolleys.
- horizontal phase - the air enters the chamber through the top nozzles and enters the product trolleys from above. Then it is sucked out by the ducts above the carts.

The amount of air from the left and right side changes smoothly from minimum to maximum in both phases. DAF 1 is suitable for chambers especially for KMD chambers up to 6 carriages.

2. DAF 2 (Dual Air Flow system 2)

- vertical phase - the air enters the chamber through the vertically positioned nozzles, passes through the product trolleys and is sucked out through the ducts located above the trolleys.
- horizontal phase - the air enters the chamber through the top nozzles and enters the product trolleys from above. It is then sucked out through lower channels located in the bottom of the chamber along the walls.

The amount of air from the left and right side changes smoothly from minimum to maximum in both phases. DAF 2 system is suitable for chambers especially for KMZ or KMU chambers up to 4 carriages and KMD for up to 6 carriages. It is very suitable for products with greater dehumidification and for trucks over 2m.

3. CrossFlow system

The direction of flow from top to bottom - the circulating air is fed into the chamber from above by means of ducts located above the trolleys and sucked out through the ducts located along the chamber walls.

Bottom upward direction - Circulation Air is fed into the chamber from below through channels along the walls and sucked out through the ducts above the carts. The amount of air from the left and right side changes smoothly from minimum to maximum in both phases.
The CrossFlow system is suitable for larger KMD chambers with a width of 7 trucks. It is very suitable for products with greater dehumidification and for carts over 2m.

CLASSIC air flow systems

Conventional airflow systems are simpler than alternating ones. They are particularly suitable for products with low average dehumidification up to 1% / 24h.

1. Classic System- Circulation air is supplied to the chamber vertically through ducts located along the walls and sucked out through ducts located above the carts. The amount of air from the left and right side varies smoothly from minimum to maximum.

Recommended use: For KMZ, KMD and KMR  air-conditioned chambers

2. Central System- Circulation Air System is distributed through a central 3-chamber channel located above the carts. The central part of the channel serves to extract air from the chamber, the side parts serve to horizontal distribution of air into the chamber.

Recommended use: KMD and  KMR air-conditioned chambers in atypical shape rooms.
