CRAC Units – also known as Precision Air Conditioning – our highly efficient Computer Room Air Conditioning (CRAC) units included air cooled, water cooled and chilled water variants.

The full range of Aqua Cooling’s Data Centre precision air conditioning CRAC units covers DX air cooled, DX water cooled and chilled water units. In addition, when our chilled water CRAC units are combined with our Queen’s Award-winning Leak Prevention System (LPS), leak-free operation is guaranteed!

Case Study

Keeping the World’s Data Cool

4D Data Centres is a UK-based colocation provider, providing ultra-fast connectivity, business-focussed cloud and cyber solutions to organisations around the world. Data centres are at the heart of nearly all internet-based technologies, including Facebook, Google, WhatsApp and Amazon. Keeping all this technology online takes a lot of power, not only to run the computers themselves but also to keep them cool, otherwise they would quickly overheat. When 4D took over an existing data centre building at Gatwick, Aqua was selected for its ability to upgrade the existing chiller-based cooling system, with installation and commissioning taking place whilst the facility was live. Working in direct partnership, Aqua designed and built an intelligent, energy efficient data centre cooling solution that significantly reduced the need for mechanical cooling and provided fresh air free cooling. The project design focussed on a bespoke solution with energy efficiency, system resilience and reliability at its heart. It was critical that it was completely scalable, future proofing the client’s business model, allowing them to scale up to high density capacity at 40kW per rack when market demand required. Aqua’s ‘water tower’ system uses evaporative cooling to lower the temperature of the computers in the data centre… Read More

Downflow Units

downflow

Air inlet at the top air outlet under the floor. This unit is a DX or refrigeration version, with on-board scroll compressors. With the condenser located outside the building. These compressors could be either on/off compressor, or optionally inverter controlled for better energy efficency. The units have a range of additional options, to personalise the unit for the user, including as shown above humidifier.
