Warning of gases with LPG / LNG / CNG

Gas detectors for LPG applications: Explosion protection and safety through reliable gas detection

LPG (LPG / liquefied petroleum gas)

Often used in households, mobile homes, BBQs, heaters and LPG systems.
Colorless and odorless, is provided with odorants (odorization).
Explosion hazard with leaking systems in closed rooms → Gas alarm recommended.

LNG

Energy-efficient for heavy-duty transportation & shipping due to high energy density.
Due to the extremely low temperatures, special materials & safety protocols are required.
Becomes gaseous when heated – the volume increases approx. 600-fold.

CNG

Widely used in city buses, cabs and municipal vehicles.
Inexpensive, environmentally friendly fuel (less CO₂ than diesel/petrol).
High pressure requires robust tanks and safety valves.
Light gases rise upwards in the event of a leak – lower risk in open spaces.

Why gas detectors are indispensable for LPG applications

LPG consists mainly of propane and butane, two highly flammable gases. As LPG is heavier than air, it often collects near the ground, in cellars or pits in the event of a leak – without being noticed immediately. Even a small amount in the air is enough to create an explosive gas-air mixture.

Modern gas detectors protect people, systems and buildings by detecting critical concentrations at an early stage. They provide a reliable warning before ignition can occur due to static discharge, electrical systems or open flames.

Typical areas of application for LPG gas warning systems:

Storage and tank areas for liquid gas
Gas filling stations and filling systems
Liquid gas heating systems and industrial furnaces
Vehicle halls with LPG-powered industrial trucks
Indoor areas with LPG consumers (e.g. camping, commercial kitchens, workshops)

Our solution: Efficient gas detectors for the safe handling of liquid gas

Our gas warning systems for LPG offer:

Reliable detection of propane, butane and other flammable gases
Fast response times for maximum safety in the event of danger
Explosion-proof device variants (ATEX-compliant) for Ex zones
Modular system solutions for individual areas or complex systems
Integration in building management systems, fire alarm systems and control systems
Ease of maintenance and simple calibration

Safety when using LPG starts with smart gas monitoring

Whether in industry, trade or the private sector – anyone using LPG must be aware of the risks. Our gas warning devices offer reliable protection against explosions, enable safe operation and help to reliably fulfill legal requirements (e.g. BetrSichV, TRBS, ATEX).
