Winner of ‘Datacentre Energy Efficiency Product of the Year’ at the 2014 Datacentre Solutions Awards and ‘Commercial Building Services Product of the Year’ at the 2014 H&V News Awards, the SmartCool™ is developed to meet demand for an ultra-efficient, dedicated chilled water PAC system that delivers extremely quiet and accurate climate control for critical data centre applications.

The SmartCool™ CW delivers up to 30% more cooling kW/m² when compared with competitor units, keeping footprint to a minimum to free up premium IT space.

Applied cutting edge technology enables the SmartCool™ to quietly and precisely control room temperature, humidity and air quality to ensure efficient, reliable, 24/7 operation of sensitive systems in data centres and other critical applications.

Optimise your unit selection
The SmartCool™ gives you the flexibility to optimise unit selection to match the considerations of your specific project – whether a new or retrofit application or driven by cost, efficiency, space, noise, resilience and/or ambient conditions.

Choose from over 150 downflow models available in:

  • 8 system types
  • 17 case sizes
  • Single or dual circuit featuring: DX air cooled (16kW – 137kW); DX water cooled (60kW – 137kW); Chilled water (11kW – 233kW)


  • EER of up to 52.4 (SN06D010-C000-0)
  • 46% energy saving in free-cooling dual cool variant
  • Up to 88% saving in power input with hot gas re-heat option
  • EER 34% more efficient than previous generation CRAC units


  • High level of capacity control with up to six stages of DX cooling across single and dual circuits (model dependent)
  • 30-90Hz inverter compressors provide 17-100% variable cooling exactly matching cooling load
  • Less space claim. 16kW – 60kW DX models provide up to 17% more cooling kw/m²

Operational Costs

  • Virtually all 16kW – 60 kW models included on the Energy Technology List, offering potential for 100% first year capital allowance
  • Free cooling, dual cool models can save up to £8,000/year or 31,000kg of CO² compared with a standard DX system (£0.11/kWhr)
  • Exact capacity match provides 10% reduction in running costs representing £1,162p.a (compared with a comparable unit with a fixed speed compressor over a year)

Quality / Reliability
