1. Cooling
Rittal Cooling Application Guide
CRAC and Chiller Systems up to 118 kW
IT chillers and CRACs in conjunction with freecooling ensure efficient cooling and supply of the cooling medium.
Safety-relevant options such as redundant pumps, emergency cooling and buffer stores ensure maximum operational
reliability and fail-safeness.
LCP T3+ Maximum reliability with redundant cooling and power up to 24 kW
At the heart of the LCP T3+ are two embedded cold water circuits, each of which supplies 100% of the nominal cooling
output. The power supply to the fans also has a completely redundant layout.
LCP Plus - High density rack cooling up to 30 kW
Air/water heat exchanger, bayable with server racks based on TS 8. Complete unit with 30 kW useful cooling output.
The separation of cooling and rack prevents the ingress of water into the server rack, making it easy to assemble and very
service-friendly.
LCP Inline - Modular Liquid cooling up to 60 kW
Based on the LCP Plus design the air is delivered directly into the cold aisle rather than the rack. With superior resilience
modularity it is a perfect cooling method for cold aisle and hot aisle containment systems.
Vertical ventilation up to 3 kW
Ventilation base/plinth, roof vent and slotted component shelves ensure effective heat dissipation.
Horizontal ventilation up to 5 kW
A high air throughput, stylish design and outstanding security are provided by the perforated doors
(with 82% open area per door).
Hot Aisle Containment up to 10 kW
Separates the hot air from the cold. Utilising in line coolers the hot air is extracted and cooled to provide cold air to the front
of the server.
Cold Aisle Containment up to 10 kW
Traps the incoming cold air in front of the server inlets. Can either use inline cooling or CRACs to provide the cold air.
LCP Passive Retro-fittable cooling up to 20 kW
Perfect for dealing with any hot spots with in the Data Centre

3. What is best, Hot or Cold Aisle Containment?
In short both systems do the same thing, they both raise
Cooling the return temperature to the cooling system, whether that
is CRACs or Inline cooling. Therefore it is the application
that decides which is best.

temperature can be raised, this means the CRAC or Inline cooling (LCP Inline) system is a lot more energy efficient which
results in long-term energy cost savings.
Hot Aisle Containment Key Points
 Cold and hot air cannot mix, warm air does not flow into the cold aisle
 The system can be operated with a much higher extracted air temperature.  Contains the hot air within the aisle
 Standard air circulation cooling units are operated at an optimum thermal efficency level  Increases cooling capacity to 10 kW+ per rack

the containment dimensions and secondly the cooling system required.
The containment system is made up of roof panels and end doors. The roof panels bridge across the aisle between the racks
and the aisle and doors then close off the aisle. The roof sections are specified on the width of the aisle and the width
of the rack that they need to be secured to. The end doors quite simply match the height of the rack.
