Freon(R134a)The alarm is a toxic gas detector with modular design, intelligent sensor detection technology, and overall flameproof(d)structure, fixed installation method toxic gas detector. Standard configuration is with dot matrixLCDLCD display, three-wire4~20mAAnalogRS485digital signal output, optional configuration is programmable switch quantity output and other modules, users can provide customized products according to their own needs, and also support output signal fine-tuning and other functions, convenient for user system networking and maintenance.
Freon gas alarm, NDIR infrared, range 0~1000ppm; alarm parameters can be locally adjusted; IP65; audible and visual alarm; DC24V; building BA system integration; office building refrigeration room.
Freon alarm (refrigerant leakage alarm) is designed for R22、R134a、R410A、R404A and other refrigeration refrigerant leakage developed industrial online monitoring alarm equipment, widely used in refrigeration machine rooms, cold storage, central air conditioning machine rooms, food quick-freezing workshops, pharmaceutical cold chain, chiller rooms and other places, real-time monitoring of Freon gas concentration in the air, preventing suffocation risks, equipment damage, and environmental safety accidents caused by refrigerant leakage.
Freon gas alarm, NDIR infrared
Mainstream equipment adoptsNDIR Non-dispersive infrared sensor, compared with electrochemical sensors, it has advantages of strong anti-interference, no gas poisoning, long service life, small zero drift, and is not affected by conventional environmental factors such as oxygen, water vapor, and dust. The detector uses diffusion sampling, wall-mounted installation,DC24V Industrial power supply.
Core functions: real-time digital display of gas concentration, supports high and low two-level alarms, alarm threshold customizable; after triggering alarm, local sound and light prompt, simultaneously outputs 4-20mA Analog signal,RS485 Modbus communication signal and relay passive switch signal, can link exhaust fan, refrigerant cut-off solenoid valve, connect to PLC、BA Building automation,SCADA system, realizing remote monitoring and automated emergency response.
The housing is mostly cast aluminum alloy explosion-proof shell, explosion-proof rating Ex d II CT6, protection rating IP65/IP66, dustproof and waterproof, adapts to - 20℃～+50℃、10%～95% RH(no condensation) machine room working conditions. Range optional 0~500ppm To 0~2000ppm, detection accuracy ±5% FS, fast response, supports networking of multiple detectors, some models can store alarm records, convenient for operation and maintenance traceability.
Freon gas alarm, NDIR infrared
The whole system consists of detector + alarm controller. Detectors are deployed at refrigerant pipelines and unit leakage-prone points, the controller is placed in the duty room, centrally viewing concentration and alarm status of all points, meeting safety production standards of the refrigeration industry, and is an essential safety monitoring device for cold storage, central air conditioning, and industrial refrigeration systems.
