Cooling strategies. Aisle containment.

An economical solution to improve the performance of any cooling system.

Benefits• Increased airstream management• Supply air and return air do not mix• Uniform distribution of cold air• Higher delta T for increased efficiency• Modular, scalable, and retrofittable• Can be used with perimeter-based cooling• Can be used with row-based cooling




When to use aisle containment• Issues with bypass air• Issues with hot air recirculation• Issues with hot spots• Issues with uneven cold air distribution• Issues with maximum cooling capacity

Hot and cold air distribution with and without containment.




Why aisle containment works• Prevents hot and cold air from mixing• Higher supply air temperatures

• Increased energy savings!• Increased economizer hours

• Increased energy savings!• Increased cooling efficiency

• Increased energy savings!




Cold aisle containment benefits• Precise, targeted cooling• Consistent air temperature

• Eliminates hot spots• No raised floor required• Minimal infrastructure requirements

• Creates easy retrofit installations• Using only doors shows increased efficiency

• Prevents end of row recirculation




Hot aisle containment benefits• Work environment is flooded with cold air• Hot air can be ducted back to CRAC

• Increased efficiency• Consistent air temperature

• Eliminates hot spots

Rear DoorLCP Passive CW


Rittal Liquid Cooling Packages. LCP Passive CW.

Features• Passive rear doors are designed to be

installed as a replacement rear door for the racks on which they are installed

• A passive rear door simply has the fan system removed from the equation, allowing the server fans to do the necessary work of moving the air through the heat exchanger

• Maximum energy efficiency as there is no electrical power consumption

• Uses chilled water as the rejection medium

• HxWxD: 80x24x6 in. (2000x600x170 mm)• 20 kW cooling capacity

Electrical Design• Wide input voltage range

• 208V, 230V, 400V• EC fan technology

• 1 year ago: step motor technology• Rated current: 6.5A

• 1 year ago: 11.5A• Power rating: 1050W

• 1 year ago: 2650W• 5 pole terminal block• Fuses are easy accessible by

opening the rear door• Every unit comes high voltage tested• EMC tested configuration



Features Summary• Auto-Temperature-Control:

Cold air inlet temperature automatically controlled via integrated controller board

• Monitoring: Integrated controller with Rittal Basic CMC

• Intelligent sensor network: Fault tolerant sensors for water inlet/outlet temperatures, air inlet/outlet temperatures, water flow rates, leakage, etc.

• Fault tolerant controller boards and systems: In the case of electronic failures the valves will open and the fans will provide maximum airflow

• Alarm / events / sensor logging

• Three fan controller boards + one water controller board (individually fused)
