R Series – Close Control Air Conditioners for “In Row” Installation

• The racks containing servers are increasingly positioned according to the Hot Aisle and Cold Aisle layout.
• Air temperatures are allowed to rise up to 30-35°C in the hot aisle and 20-25°C in the cold one, with very low humidity (never above 30%).
• Server performance is increasingly on the rise, while server sizes are increasingly reduced. As a result, many more servers can be installed in a rack, so some of these racks can be eliminated as they are empty. At the same time, heat dissipation increases, thereby requiring more power from air conditioners.

R series air conditioners are designed and built so as to fit into this plant layout perfectly. As a matter of fact:

• They exploit the space left free from racks and allow cold air to be distributed as close as possible to servers, that is, where heat is generated.
• They feature rear intake from the hot aisle and front supply to the cold aisle with a horizontal flow. The horizontal flow reduces internal pressure drop, with a consequent reduction in the power draw of the fan.
