Everyday we come across a news of hazardous incident of fire in plant,  hotel, resident, industries, etc, the tragedy happen due to the leakage of combustible/explosive gases or sudden electrical spark and the carelessness of the management and security systems.

we all know that in market there is lots of gas leak detection and early fire detection system and gas leak detection systems which stop the horrible incident by intimating the managements by actuating  Alarm, locking gas Supply System or can say close the solenoid valve , messages & many more options are there .

But sadly saying that in India 60%people who needs fire and gas leakage monitoring and control system in their premises are not using these system in their premises .

We request you to put your concern towards the security system, Life and Environmental issues and stop these kind of painful incident in our country.

For all types of gas detector process instruments  energy saving & field instruments you can contact us

We feel pleased if we can assist you, guide you and provide you our best consultancy and product services.

We at Alvi Automation promise you to provide you best German Technology to save your Life, Money, Plant, Industries, Building etc. ..

Lithium- Ion Battery Fires – Hydrogen Fluoride Detector

Gas Safety Risks: Lithium- Ion Battery Fires – HF (Hydrogen Fluoride Monitoring Systems)

Li-Ion batteries are now widely  used in mobile phones, electric vehicles, laptops including MW range of Renewable Energy Storage plants, aircrafts, submarines, mine-shafts and spacecrafts.

Gas Safety risks  in Li-Ion battery charging rooms:

  • Li-Ion batteries when overcharged or short circuited are overheated and catch fires
  • Li-Ion battery fires have caused great concern because of risks due to spontaneous fires and intense heat generated by such fires
  • As a result of the above-said a lethal amount of toxic Hydrogen Fluoride Gas, HF is generated.
  • HF from Li-Ion battery fires can pose severe gas safety risks in confined spaces like battery charging rooms, renewable energy storage plants in solar or wind power plants
  • The electrolyte in Li-Ion battery is flammable and generally contains Lithium Hexa- fluoro -phosphate (LiPF6)
  • In the event of overheating due to overcharging or short circuiting  and backed by high temperature, the electrolyte in Li-Ion batteries will vaporise liberating toxic gases like CO, CO2, HF (hydrogen fluoride)
  • The moisture and humidity will further exacerbate the situation generating more HF (reaction of LiPF6 with water or humidity)
  • Typical HF concentration expected can be as high as 20-200 ppm of HF (NIOSH/USA Safety limit , TWA:3 ppm HF, STEL: 6 ppm HF)


  • Continuous monitoring of HF, Hydrogen Fluoride in toxic range of NIOSH/USA : 0-10 ppm
  • Continuous monitoring of other toxic gases like CO, CO2 (gases generated due to  combustion fires)
  • Continues monitoring of humidity and temperature
  • VEFSA (Very early fire and smoke alarm)

Typical Systems:

  • Single Point stand alone gas controller for HF, CO, CO2, Temperature, Humidity
  • 1-4 channel HF, CO, CO2 Sensor/Transmitters with 4 channel Gas / PLC controller
  • Warning alarm to plant people including GSM Alarm dialler capability to mobile phones
  • DIGITAL MULTI-CHANNEL system for Renewable Energy Storage Plants for HF, CO, CO2, Temperature, Humidity
  • Save 60-80 % costs on cable, cabling, installation with our DIGITAL SYSTEM

VEFSA: Very Early Fire and Smoke Alarm: For very early fire detection in electrical cabinets, switchgear rooms. Our sensing system is designed to pick up enhanced gas radicals which are liberated during overheating of PCBs, electrical insulation breakdown due to short circuit or earth fault, transformer insulation breakdown, again due to short circuit or earth fault. Please note  by the time the conventional fire detection system like VESDA or conventional smoke sensors  pick up the smoke, it is already too late. Our VEFSA Gas Radical Sensing System can detect the gas radicals and shut off the mains/power supply thus protecting millions of dollars of assets
