CRAC stands for Computer Room Air Conditioner, which is a machine used to measure, preserve and control the temperature and the distribution of airflow in datacentres using perforated air tails.The process is carried out by having cool air stream through the racks where the air gathers heat and flows out of the rack.Split air conditioning, on the other hand, cannot manage the air distribution, or humidity like CRAC.

Cold aisle management provides enhanced and improved airflow, higher density installation, improved heat exchange via air handler capacity, and central plant energy efficiency by giving and obtaining elevated water temperatures. It also has the ability to isolate hot aisle and cool aisle. These benefits allow you to save costs while enjoy well-managed air flow in your data centre.

If you are looking for a fast solution for putting out fires, then the fire suppression FM-200 system is your answer.The FM-200 system generates a transparent, no-side- effect gas that distinguishes fires in a matter of seconds, resulting in less damage and hence, reduced expenses and increased safety in your data centre.
Environmental monitoring systems allow you to observe and manage conditions such as the temperature, humidity, airflow, water, energy, light, sound…etc. in your data centre, resulting in a well-managed and secure environment for your machines.

Environmental monitoring systems send notifications (Email, SMS and SNMP traps.) or alerts (via alarm) in case any sudden changes that could threaten its surroundings occur, such as a considerable rise in temperature (above the average level) as this could be the result of fire.
