– The highly efficient EC fan saves more than 30% energy than a common
fan.
– The direct drive that the fan adopts has higher transmission efficiency
than the belt drive, which reduces belt replacement and routine checks.
– Compared with the fan speed control by the belt drive, the fan speed
control by direct drive has a wider application range which is not subject
to the transmission ratio.
– The EC fan is controlled over RS485. You can view the fan power and
speed status in real time over LCD and can obtain fault information
including fan blockage, overvoltage, and undervoltage. The features allow
you to view the status and locate a fault.
Air filter
The G4 air filter is used, and the F5 air filter is optional. The air filter meets
cleanliness requirements for customers' data centers. The air filter of
downflow smart cooling products is paved on the heat exchanger, ensuring
easy maintenance and reducing air resistance.
(Optional) Wet film humidifier
– The wet film humidifier uses wet film for humidification and therefore
has low water quality requirements and high environment adaptability. In
most cases, household water can be used without being processed
specially.
– It has a simple structure and is easy to remove, clean, and maintain.
– It can quickly start and bring huge humidification capacity.
– It consumes low power, saving more than 95% energy compared with a
traditional electrode humidifier.
(Optional) Electric heater
– The positive temperature coefficient (PTC) electric heater automatically
adjusts heating capacity and provides multiple protection measures to
ensure secure and reliable operating.
– The heater features quick start, large heating capacity, and even heating.
(Optional) Motorized damper/Gravity damper
When a smart cooling product is powered off, the damper is closed
intelligently to prevent loss of air volume and cooling capacity.
(Optional) Fresh air free-cooling damper
It fully uses the outdoor natural cooling source, intelligently adjusts the fresh
air and return air ratios and fan speed, and saves energy by over 30% a year
compared with the traditional chillers.
(Optional) Differential pressure sensor
– It adjusts air volume based on the differential pressure to ensure precise
air supply. No excessive adjustment helps save energy and reduce power
consumption.
– The air supply volume is also sufficient, which helps eliminate hotspots
and improves reliability.
Differential pressure switch
When the air filter is dirty or blocked, the differential pressure switch triggers
an alarm, prompting for air filter replacement.
