Dehumidifiers for Data Centers and Server Rooms


Humidity control of data centres is essential since there are lot of sophisticated equipment in a data centre. Also, a data centre generates humidity because it works at a low temperature. Datacenter dehumidifiers are effective in reducing the humidity.

How to reduce humidity in data centers and server rooms?


One reason why data centres need to control humidity is that humidity can cause electrostatic discharges. Our data centre monitoring systems will give you exact data on humidity among other parameters. These discharges damage servers and bring costly repair bills as well as other inconveniences. Low humidity and high humidity can cause damage to the equipment in a data centre.
To keep their servers running in optimum condition, the humidity in the room has to be controlled.

In order to control the humidity in a data centre, you need to use dehumidifiers. We normally use condensation dehumidifiers for data centres. While selecting the right dehumidifier, you need to calculate the required capacity. You can use our free software for deciding the dehumidifier sizing. You need to have the size of the room, normal temperature and normal humidity. A dehumidifier machine extracts water from the air and drains out. We will explain some of the popular models of our data centre dehumidifiers.

Effects of high humidity in data centres

You may not realize it, but humidity does affect machines. But it isn’t one humidity extreme or the other, both humidity extremes tend to bring some sort of damage to data servers.
Controlling the humidity in data centres becomes very important. For example, low humidity levels bring the possibility of static damage to the servers. High humidity levels tend to ruin electrical equipment (Read more about our Static Electricity Dehumidifiers) and contribute to the swelling of printed circuit boards.
Both problems lead to equipment breakdown and an interruption in service. An interruption in service can cause loss of revenue and many other business headaches to a company.


It is no wonder that data centres spend an enormous sum of money regulating their data server rooms. They need to do this in order to protect their investment and equipment. These data centres try to keep the temperature and humidity levels in their server rooms at optimum levels.

For temperature, the ideal level is between 60 degrees F on the low side of the scale and 80 degrees F on the high side. Anything outside of this comfort zone could create problems for the data centre.

Humidity also has its optimum level as well. The low end of the scale is set at 40 per cent and the high end is capped at 60 per cent relative humidity. But these two levels are not the only ones that need to be regulated.
The dew point must also be monitored to ensure the equipment is operating in prime environmental conditions. The recommended lower dew point level stands at approx. 42 F, while the top end levels out at 59 F. All three levels must be regulated to maintain the best environment for data servers.

Condensation dehumidifiers for data centres


One of the biggest problems for data centres is condensation. This condition can cause a lot of problems including, but not limited to, loss of data, electrical sparking and short-circuiting.

A dehumidifier generates temperature. You need to consider this during design calculations.

Condensation dehumidifiers can intake the atmospheric air which will be humid. The machine then condenses the air separating water. The exhaust air will be drier than the intake. These dehumidifiers operate by condensing air on its cold coils, then drain the water safely through a drain pipe.

They keep the servers safe from any water and electricity contact. The key to using condensation dehumidifiers is in the calculation. By that, we mean that you just cannot go out and buy a condensation dehumidifier and keep it in your server room.
The unit you buy may be too small or the room may be too large for the proper regulating of humidity levels. You need to calculate the size of your room and the nature of the problem.

Then you need to check the capacity ratings of the condensation dehumidifier. In the end, you probably need more than one and they all need to be placed in strategic locations in the server room.

Making the right calculations and buying the right condensation dehumidifiers and the right number will save you a lot of money. Based on the size of the room, temperature etc. you may have to select the type of dehumidifier. We have floor-mounted, wall-mounted and duct mounted models of data centre dehumidifiers.

Why desiccant dehumidifiers are not the best choice for data centres?


One reason why the desiccant dehumidifier is not good for a data centre is that it produces heat. Condensation dehumidifiers also produce a little heat. But desiccant dehumidifiers work on a method involving heating up the rotor. However, your cooling system can take care of this excess load, you can consider them.

Also, desiccant dehumidifiers produce a foul odour of dry air. The interior mechanism of the desiccant dehumidifier generates dry air, which has an arid smell.
This odour then is subsequently discharged with the dehumidified air. There are a lot of other design factors also to consider while selecting a dehumidifier. Please contact our office for more details.
