The efficient combination of vortex variable-frequency compressor and EC fan
Hotspot Management
The wind speed and volume can be adjusted conveniently. The residual pressure outside the machine can reach above 50 Pa, meeting higher air supply requirements.
Additional cooling is provided when necessary.
Direct expansion system with variable frequency technology.
Wind volume adjustment according to the actual heat load.
Characteristics
Vortex variable-frequency compressor: Environmentally friendly and energy-saving
High-efficiency EC fan: Noise level is 4-5 decibels lower, and electricity consumption is reduced by 15%
The controller uses 4 sensors to collect temperature data for calculation, solving the problem of temperature stratification in the rack
Easy scalability: It can be combined with multiple mainstream racks to dynamically match the heat load of servers. Standardized design and easy expansion capabilities
