Heat exchanger
The A-type or V-type finned-tube exchanger with a high cooling efficiency adopts the
synergy field principle and computational fluid dynamics (CFD) to optimize the flow
path design, which greatly improves the heat exchange efficiency.
Chilled water valve
The chilled water valve, also known as the chilled water proportional integral regulating
valve, features incremental proportional integral and derivative (PID) control with
precise adjustment and accurate control.
EC fan
−
The EC fan uses a high-end brand and provides high reliability and long service
life.
−
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.
