A list of all the equipment that can be linked with the explosion-proof FFU intelligent control system
Explosion-proof FFU Intelligent Group Control System， supports signal interlock， automatic start-stop， wind speed linkage， and fault linkage with explosion-proof， clean workshop， fire safety， and environmental monitoring equipment. It is compatible with lithium batteries， pharmaceuticals， chemicals， and dust explosion-proof clean workshops.
1. Environmental Detection Type (Most Commonly Used， Must Be Linked)
Gas detector (explosion-proof) Hydrogen， electrolyte vapor， ethanol， acetone， VOC gas concentration exceeds standard → Automatically increase FFU wind speed， force ventilation， interlock exhaust， dilute flammable and explosive gases.
Dust concentration detector (explosion-proof) Dust concentration exceeds standard → FFU automatically increase air volume to suppress dust cloud aggregation and reduce explosion risk.
Temperature and humidity sensor Temperature and humidity exceed standard → Link FFU wind speed adjustment， cooperate with air conditioning to stabilize workshop environment.
Differential pressure sensor / Workshop differential pressure monitoring Pressure imbalance between clean area and non-clean area → Link FFU to automatically adjust speed， maintain positive pressure / negative pressure gradient.
2. Fire Safety and Security Type (Compliance with Safety Assessment， Fire Inspection Mandatory Linkage)
Smoke detector， temperature detector
Fire alarm host， fire control module Fire alarm triggered → According to regulations， automatically shut down explosion-proof FFU or maintain specified mode operation to prevent fire from spreading along the air duct.
Three, purification air conditioning ventilation class
3. Purification Air Conditioning and Ventilation Type
Purification air conditioning unit， combined air conditioning cabinet FFU and air conditioning interlock start-stop synchronously； load matching to avoid cold and hot imbalance， energy waste.
Explosion-proof damper， electrically sealed damper Gas or fire alarm → Link to switch damper， form fresh air ventilation / Isolate partition area.
Exhaust fan， explosion-proof exhaust fan Gas or dust exceeding standard → FFU + explosion-proof exhaust fan linkage variable frequency， quickly replace dangerous air.
Fresh air fan， booster fan Maintain workshop positive pressure， and FFU wind speed do closed-loop linkage adjustment.
4. Clean Room Supporting Automatic Control Equipment
Laminar hood， explosion-proof weighing room， negative pressure isolation room Same as clean area equipment unified group control， synchronous speed adjustment， timed start-stop.
Washroom， cargo washroom Personnel / Cargo entry and exit → Link FFU to temporarily increase wind speed to maintain local cleanliness.
High-efficiency air outlet， static pressure box self-control module Coordinated operation of the entire purification air path system.
5. Factory Intelligent System Upper-Level Linkage
BA Building Automation System
MES Production Management System
PLC Industrial Control System
SCADA Configuration Software
Explosion-proof FFU connects to the factory main control through Modbus/RS485 / Ethernet to achieve centralized scheduling， time sequence start-stop， energy consumption statistics， and data cloud transmission.
6. Electrical Distribution Safety Type
Explosion-proof distribution cabinet， UPS Uninterruptible Power Supply Power failure switch UPS → FFU operates at low power to maintain clean environment from collapse.
Electrical abnormality， overcurrent， temperature control protection module → Automatically interlock FFU to stop operation to protect clean environment from explosion ignition.
