A comprehensive range of Computer Room Air Conditioning Units (CRAC units) or Computer Room Air Handling Units (CRAH units) that provides precision cooling to data centre environments. 

About CRAC/CRAH Units

Both CRAC and CRAH units keep the temperature, humidity, and air distribution to precise set points to optimise the performance of critical data centre hardware.

Different configurations are available depending on the application and can be combined with our award-winning Leak Prevention System, to create a secure data centre environment.

With decades of process industry experience behind us, we understand the challenges and key issues faced daily within businesses running critical process applications, such as data centres, laboratories, and research & design facilities. We take a holistic, consultative approach to every project and appreciate the importance of integrating technologies and the impact downtime can have on a 24/7 operation.  Regardless of whether your system includes CRACs, CRAHs, rear doors, in-rows, HPC or hot spots, we’ll ensure it comes together seamlessly, giving you the very best, most energy-efficient solutions for your specific needs.  We can even design a system using natural coolant sources.

As well as our Sales & Projects team, our directly employed Service Engineers are on hand to support you 24/7 and we offer fully bespoke, priority response Preventative Maintenance Plans so that we’re on hand when you need us most. Our Hire division also offers full contingency planning, ideal for critical sectors such as data centres and telecoms.

Our CRAC and CRAH Range

Our range of highly efficient CRAC units includes direct expansion (DX) air-cooled, (DX) water-cooled and chilled water models. Units can be supplied with external remote condensers and free cooling coils. 

CRAH units incorporate a highly efficient chilled water coil, designed to operate at high water temperatures.  This allows approach temperatures, between the air off temperature and water on temperature, as low as 3˚C.
