Gas warning systems for transport & logistics – safety when handling LPG, LNG & CNG

Liquefied petroleum gas (LPG), liquefied natural gas (LNG) and compressed natural gas (CNG) are becoming increasingly important in the transportation and logistics sector – whether as alternative fuels, in temporary storage or for handling in freight forwarders, ports and filling stations.

What is often underestimated: These energy sources are highly explosive, invisible and life-threatening in the event of a leak. Without reliable gas monitoring, dangerous situations can quickly arise – for example due to leaks, faulty connections, tank operations or mechanical impacts on containers.

What is LPG, LNG, CNG?

  • LPG (Liquefied Petroleum Gas): mostly propane/butane, stored as a liquid under pressure
  • LNG (liquefied natural gas): highly cooled methane, liquefied at -162 °C
  • CNG (Compressed Natural Gas): gaseous methane, stored under high pressure
Typical areas of application:

  • Refueling and storage in vehicle fleets, logistics centers, bus and truck depots
  • Gas-powered vehicles in closed workshops or garages
  • LNG/LPG filling stations, transshipment terminals and port facilities
  • Temporary storage for gas cylinders or pressure vessels
Relevant risks:

  • Explosion hazard in case of leakage in closed or poorly ventilated areas
  • Displacement of oxygen (risk of suffocation) by methane or propane
  • Cold burns with LNG due to contact with cryogenic media
  • Unnoticed leaks – as the gases are odorless and colorless (sometimes only with odorization)
Why gas warning systems are indispensable:

  • Early detection of leaks or hazardous concentrations
  • Prevention of explosions or suffocation accidents
  • Safe operation of filling stations, vehicle halls, workshops and storage rooms
  • Compliance with legal regulations (ATEX, BetrSichV, TRBS, DGUV, ADR)
Our solution: Intelligent gas monitoring for transportation & logistics

We offer tried-and-tested gas detection systems for all critical areas – whether stationary in tank areas, mobile for maintenance work or networked in logistics centers.

Your advantages:

  • Early warning for methane, propane, butane & co.
  • ATEX-certified technology for potentially explosive areas (Zone 1/2)
  • Automatic control of ventilation, shutdown or alarms
  • Interfaces to door control, BMS or fire alarm technology
  • Robust, maintenance-friendly systems for daily use
