Product Description

Small temperature control product line-EFA base station air conditioner
1. Product introduction
EFA base station air conditioner, product introduction is suitable for environmental control in equipment rooms and computing base stations. It is designed to ensure that base station equipment such as power distribution equipment, industrial process equipment, communication equipment and computers have a reasonable operating environment. It meets the heat dissipation requirements of base stations for high load and long-term continuous operation, and has the professional advantages of high reliability and high energy saving.
2. Application scope
It is suitable for unattended base stations and small and medium-sized computer rooms; special scenarios that have strict requirements on equipment stability and require 24-hour uninterrupted operation.
3. Product features
Brand-new structural layout and built-in compressor design, the energy efficiency is about 20% higher than that of ordinary air conditioners;
Air can be returned from three sides and filtered over a large area, making operation and maintenance worry-free;
The standard sensible heat ratio of the entire system is higher than 80%, ensuring that the humidity is within a reasonable range and effectively protecting electronic components;
580mm wide body air supply design, large radiation area, no dead ends throughout the air supply process;
Multiple fire isolation design, safe and worry-free;
The heat generated by insulating ceramic PTC electric heating changes with the air volume. The surface is not charged and has high safety performance.
