Please only answer if you are familiar with computer hardware and the like, thank you.

Answer 1

What are the humidity requirements, and the mechanical system?

If only a part of your warehouse needs to be dryer, section it off (as in building floor to ceiling height walls) and get a separate mechanical (air handling system) for that section.

As a retrofit to dehumidify the entire space, you have several options. 1. Get a controls consultant to look at your air handling system. Generally, the system can be set to take in as little outdoor air as possible with a very cold chilled water coil to cool the air down (this get the water out of the air - in essence, it rains in your chilled water coil), then reheat the air to the desired temperature. Also, run the system (with very little ventilation air!) as much as possible to get all of the water to rain out of the air into the chilled water coil collection pan. 2. Get a mechanical engineering consultant to look at your systems. Perhaps your wall was not put together correctly. They can add these devices called dessicant wheels to your current air handling units that will dry out the air through an absorbtion process - with less risk of baterial spread, because water will not be sitting around in your air handling unit. However, these suckers are expensive. Either way, this is a job for a professional. I'd start shopping the local building engineering firms to see what is available.

If u are assembling electronic equipment the humidity should not be below 50%. If the humidity gets below 50% u can have static electrical problems and the technicians will need personal grounding systems.
