This Inrak model can be considered the sister of this technology. Because the structure of this cooling system is exactly similar to this one, with the difference that this cooling system is coupled to a special rack from the side wall area and the cool air produced, contrary to this one (which threw the wind forward) towards the side and the rack His side throws. The door and walls of the rack and its side rack are completely airtight so that a positive pressure cold air chamber is created in front of the rack and a warm air chamber is created behind the rack, and these two spaces are connected to the cooling system of the rack through two channels.

 Compared to rack-mount racks, these systems have a higher capacity and can even support up to 2 side racks. so that one rack on the left and one on the right side of this cooling system is coupled. Also, from the point of view of the working fluid, this technology can be of both water and gas models.
