Hygiene Recirculating Air Cooler

For increased hygiene requirements

The alternative to conventional room air coolers. Ortners hygienic recirculating air coolers are clean room systems that have been specially developed for increased hygiene requirements.

Thanks to their filter technology and sterilization technology, they are a real alternative to conventional room air coolers. The area of application ranges from general cold rooms to cooled production rooms.

Principle of low- turbulence mixed flow. Designed as a room protection concept, the Hygiene recirculating air coolers operate on the principle of low- turbulence mixed flow. The flow generated in this way is ideally suited to optimally distribute the cooled air in the surrounding area without generating high turbulence or strong drafts at specific points.

A silver cube shown as seen from below. On the front left side is a depression in the form of fan blades, In the lower left corner is a blue stripe that extends to the center. On it is written "cFFU-Hygiene". In the lower right corner and in the upper right corner, a short gold colored stick comes out. On the right side of the cube, in the lower right corner is a small blue rectangle that says "ortner cleanrooms unlimited". The rest of the face, of the right side, is a grid attached to the top left and right corners with two screws. The bottom of the cube is a smooth surface.
 In the foreground, a conveyor belt consisting of rollers goes from left to right. This leads onto a conveyor belt that runs from the front right corner of the image to the center back. To the right of this conveyor belt stands a man wearing a protective suit, protective hood and mouth guard in white and blue protective gloves. In each of his hands he holds an elongated small tray with upturned edges. On these trays is meat cut into pieces. Along the conveyor belt are more such trays. To the left of the conveyor belt are stacked several white boxes. Behind them, you can also see a conveyor belt leading from left to right onto the conveyor belt with the yellow trays. In the right rear corner, there are many stacked boxes between which a person in a white protective suit and blue protective gloves is standing. To the right, several people in protective suits with white face masks are standing in front of boxes on a conveyor belt. Empty boxes hang above head height all along the room. Above the treadmills hang horizontally white thick hoses attached to boxes hanging from the ceiling.
Use in cooled production rooms
 In a large cauldron is yellow liquid with white lumps. Approximately in the middle above the cauldron is a narrow elongated box at both ends of which a thin long plate comes out. At the ends of which a short rod goes down. At the end of each of these rods is a horizontal rod. Out of this rod come eight more rods that protrude into the liquid. It looks something like very large forks. Between these two hangs one more like this.
Clean room technology for the highest hygiene requirements
 A long hallway with a shelf on the left and right side of the hallway. Per shelf there are ten shelves on which large cheese wheels lie next to each other.
The use of two filter stages as well as active UVc disinfection minimizes the microbiological risk during the production process

High Cooling Capacity

Hygienic recirculating air coolers are purely room-internal recirculating air systems (without air ducts or a connection to infrastructure ventilation systems). In conjunction with air dehumidification systems or when used in rooms with a relative humidity < 50%, media temperatures of -7 °C can be used. This means that low room temperatures or high cooling capacities can also be achieved.
