Large Air Volume Computer Room Air Handler In High Tech Workshops

Product Introduction                                     

Computer room air conditioner refers to a special precision air conditioner (also called constant temperature and humidity air conditioner) that can fully meet the environmental conditions of the computer room. It is a new model that has been gradually developed in the past 30 years. When comfortable air conditioners were used in early computer rooms, problems such as unstable operation of equipment in the computer room, interference with data transmission, and static electricity were often encountered due to improper control of ambient temperature and humidity parameters. The use of precision air conditioners can stabilize the indoor environment, ensure the smooth operation of equipment, improve equipment utilization efficiency, and save enterprise operating costs.

Benefits
