Data Centre Modules

Primary System Modules: flexible design, modular and scalable architecture

Unlike conventional monolithic “packaged” direct / indirect fresh air cooling solutions, Freecool® by Workspace Technology delivers a truly flexible architecture. Freecool® offers standardized “modules” that can be configured to create a bespoke cooling solution addressing individual customer demands.

With 30kW, 60kW, 90kW and 120kW modules, Freecool® is designed to support a wide range (<30kW to >1MW) of data centre capacities.

Freecool® Core System Modules

Evaporative Cooler

The Freecool® Evaporative Cooler module is designed to pre-cool intake air during warmer ambient conditions.

The Evaporative Cooler works on the simple principle of evaporative heat exchange. This process takes advantage of “free” latent heat which is generated as a result of water evaporation.

The Freecool® Evaporative Cooler is fitted with CELdek® filter pads which help minimise water consumption by re-circulating water through the pump and automated drainage systems.  Read more...


Air Movement

Freecool® Air Movement module is based on industry leading EC fans which consume significantly less energy than conventional fan technology.

Freecool® systems are designed with a combination of intake and exit air fans supporting N or N+1 system configurations.

Fan speeds are individually modulated via the Freecool® Crouzet controller matching cooling demands and maximising system performance.


Mixing Box

Mixing Box modules support the Freecool® Intelligent Atemperation™ mode which is designed to blend hot exit air with cold intake air to produce “controllable” equipment inlet temperatures irrespective of external ambient conditions.

The Mixing Box module is configured with volume control air dampers (VCD) modulated via the Freecool® Crouzet control system.


Air Distribution

The Freecool® Air Distribution module interconnects core sub modules to channel Hot and Cold air streams within the data centre space.

Freecool® Air Distribution module consists of bespoke arrangements to support site specific air flow requirements.

Air Distribution is created through a combination of ductwork, composite wall systems, floor and ceiling voids and aisle containment technology.


Central to the operation of Freecool® the Crouzet Control module manufactured by Schneider Electric is implemented with system sensors and site signal wiring.

The Control module sits at the heart of the Freecool® technology, configured to provide environmental control through the intelligent control of dampers and exit and intake air fans.  Read more...


Optional System Modules: indirect & mechanical modes of operation

Freecool® offers a number of configuration options, including indirect cooling through high efficiency heat exchange technology as well as mechanical backup or top up cooling.


Heat Exchange

The Heat Exchange module consists of a high efficiency cross air heat exchange system.

The Heat Exchange module is designed to support “indirect” evaporative free air cooling. Passing cool external air through the Heat Exchange module removes latent heat from the data centre air stream.

The Heat Exchange module allows data centres to benefit from the exceptional energy efficiency of evaporative free air cooling whilst maintaining a “conventional” closed loop eliminating the need for outside air to enter the data centre space.

Cool Wall

The Cool Wall module consists of a series of high efficiency chilled water coils that are typically positioned within the Freecool® Mixing Box.

The Cool Wall delivers an independent back up cooling circuit.

The Cool Wall system offers automated backup cooling for both direct and indirect cooling options with start-up based on a range of configurable environmental conditions including fire, air quality, temperature and humidity.  Read more...
