Server Rooms can be the most important room in your business, so why do you treat them like a bone yards for old outdated redundant IT equipment. Also many companies do not have protection against over heating.
Installing a quality Air Conditioning system or a Temperature Monitoring Alert System will help to protect your critical areas.
Just ask yourself how much would it cost if you lost the servers in down time or lost of data because of overheating?
A good way to cool a server room is to mount a ducted unit outside the the server room and duct in and out, advantage, any leaks are outside the area and service work can be carried out, away from the servers.(image 1)
Another way is a wall mount type position correctly, this is normally a cheaper option but work just as well.
