Name Description
Air supply ● A Huawei-developed high-speed fan is used, which
fan features large air volume, high static pressure, high
reliability, and a long service life.
● The fan is separated from the drive. The fan efficiency is
improved by more than 8% compared with a common EC
fan.
● The direct drive that the fan adopts has higher
transmission efficiency than the belt drive, which reduces
belt replacement and routine checks.
Compresso ● The FusionCol8000-E uses a DC variable-frequency
r compressor that features compact size, light weight, a
long service life, low noise, easy installation, high
reliability, stability, and energy efficiency.
● The high-precision drive automatically adapts to the
system pressure fluctuations.
● The drive conducts precision self-check. Compressor and
drive faults are separated.
Compresso ● The variable-frequency compressor drive, water pump
r drive drive, and 24 V power module are integrated into one
device to save space in the smart cooling product and
improve efficiency.
● The compressor drive is controlled over RS485. You can
view the drive running status and parameters on the
display module in real time to facilitate fault locating.
Liquid ● Liquid level sensor (at the bottom of the precooling
level module): A high liquid level sensor is added under the
sensor precooling module. If the precooling module is abnormal,
an alarm is generated in advance.
● Liquid level sensor (inside the spray water tank): There are
three liquid level sensors in the spray water tank, which
are associated with the water refill and drainage systems.
If the water level in the water tank is lower than the low
liquid level sensor, water refill starts. If the water level in
the water tank is higher than the high liquid level sensor,
water refill stops. If the water level in the water tank is
higher than the overflow water level sensor, an alarm is
generated and water is drained.
