The compact footprint enables us to design around your space, ensuring you can utilise more of the building for its true purpose and deliver cost effective refit or build.

Our power management systems are able to intelligently monitor and control your power requirements.  Using the latest technologies you can save money on energy bills whilst still maintaining your critical supplies.

Using a variety of communication protocols available directly on the devices, data is easily and readily available. Through our system integration and digital services we ensure visibility of  up to date information for instant decision making and a variety of data analytics.

Simplicity and reliability through natural ventilation

With the innovative design of the naturally ventilated system, we don’t need to include cooling fans, air flow switches or their alarms. Consequently you no longer need to worry about their maintenance, replacements or associated running costs. The cleverly designed heat dissipation system provides inherent reliability so that you achieve maximum availability.
