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.
