Description
Compres
● The variable-frequency compressor drive, water pump
sor 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.
Fan drive
● Compared with fan speed control by the belt drive, fan
speed control by the direct drive has a wider application
range which is not subject to the transmission ratio.
● The fan is controlled over RS485. You can view the fan
power and speed in real time on the display module and
can obtain fault information including fan blockage,
overvoltage, and undervoltage. The features allow you to
view the status and locate a fault.
