FFU EC Large Air Volume Type

Description

The degree of cleanliness from class 1 up to 100,000 can be set and it can be set in individual areas.
Because the back in the ceiling is a low-pressure area, the potential of the leakage is extremely low.
Bay method or through-the-wall method is possible by the arrangement of the layout of FFU.
The volume of the airflow can be set at each area.
Flexible increase or change of the clean room is possible by the arrangement of FFU.
Reduce running costs and save energy by using EC brushless frequency converter motor.
Customized service available.

A. Variable speed turbo fan, low noise level, completely closed type, no dust being generated, special design of the air diversion & air duct to try to decrease the pressure drop & noise level and improve fan static pressure as well.
B. Easy maintenance & repair, the control panel has with ON/ OFF switch, indicator lamp, running indicator lamp, failure abnormal indicator lamp, and failure output of a & b dry contact.
C. with backward inclined fan impeller, dynamic vibration balance: G2.5.
D. Can be monitored and controlled by group controller.
E. Can be connected with PLC software via RS485 Modbus protocol.

Central Monitoring System

BIG AREA PC Group Monitoring System

Control the operating, stop, RPM, and monitor the operating/failure status of large quantities of FFU.
Collect signals by Gateway.
Connect to Gateway, HUB, and PC by Ethernet TCP / IP.
Can control a maximum of 96390 units of FFU.
Compatible with ACDT's graphic control software.
If ACDT's graphic control software is not used, the system can be connected by the RS485 communication interface on FMGC, built-in standard communication protocol Modbus RTU, PLC, HMI, or data collectors, and use commercially available control software such as iFIX, intouch, and WinCC.

SMALL AREA FFU Mini Group Control System

LCD screen
The User can control and set FFU from the display screen.
Monitor the status (RPM, Operating, Failure. Alarm) of FFU in a single unit, as a group, or in a loop (all connected FFU).
Control the on/off and adjust air volume of FFU in a single unit, as a group, or in a loop (all connected FFU)
Can divide all connected FFU units into multiple groups.
Can check FFU alarm code.
Built-in buzzer for failure alarm.
Can connect to PC through RS485 communication interface and built-in standard Mbodbus RTU communication protocol.
2 sets of built-in signal output, can connect according to requirement (choose two out of three).
A. Differential pressure gauge abnormal signal
B. FMGC Power On
C. FFU abnormal signal
Differential pressure gauge sensor signal input (0-10V or 4-20mA)
Can add customized function (differential pressure display).
Can connect up to 255 units of FFU.
Can connect a maximum of 63 units of FMCG

Differential pressure module (Optional)

Space saving
Performance optimization
