Infiniti Cooling

Direct Cabinet Cooling Solutions

Direct cabinet or In Row cooling systems are becoming a popular design of air-conditioning installed into data centre, server & computer rooms. These CRAC units are ideal for facilities with space and height constraints and come configured as either Front or Side Displacement. 

The overall design of your data centre cooling systems should be sized to the I.T. load, with the ability to expand without disruption to critical services which avoids energy wastage due to system losses. It is vital to build redundancy into your data centre cooling systems, as CRAC units require frequent servicing every 3 months as a minimum. Redundant systems provide additional resilience and facilitate repairs during maintenance checks.

It's paramount that in row CRAC units are efficient and have a high sensible heat ratio (SHR), EC rated fans and electronic expansion values. Selecting the right cooling system will also have a significant effect on the PUE or DCiE.


Front Displacement Data Centre Cooling Solutions 

CRAC units are positioned in between the rack or cabinets with the cooler air controlled by inverter driven EC rated axial fans. The cold air flows through the grilles on the front of the CRAC directly in front of the server cabinet. These can set up with either: 

DX or Direct Expansion 

Using external condensers with copper pipe work, DX systems are considered the least efficient but offer the best resilience as every CRAC unit has its own pipe work and condenser. These data centre cooling solutions are most effective in smaller data centres and server rooms. 

Air Cooled Condensers or Dry Air Coolers Using external dry air coolers with steel pipework, they are a very efficient but a more costly cooling solution than DX. They are however, ideal for Hybrid DX or Chilled Water CRAC units combined with chillers. Their deployment is generally more suited to medium and large sized data centres. 

Chillers & Free Cooling Chillers

External chilled water units with steel pipework, these cooling solutions are very efficient and excellent for chilled water CRAC units. Free cooling chillers come combined with a dry air cooler and so are ideal when external space is restricted. Chilled water data centre cooling systems are most suited to medium and large data centres.

Side or Horizontal Displacement Data Centre Cooling Solutions

CRAC units are positioned in between the rack or cabinets with the cooler air controlled by inverter driven EC rated centrifugal fans. The cold air flows through the grilles horizontally on either side of the CRAC units directly in front of the server cabinet. These can set up with either: 

DX or Direct Expansion

Using external condensers with copper pipe work, DX systems are considered the least efficient but offer the best resilience as every CRAC unit has its own pipe work and condenser. These data centre cooling solutions are most effective in smaller data centres and server rooms.
