Gas detection
Toxic gases and explosive atmospheres rarely give warning. A reliable gas detection system is not an insurance policy – it is a necessity.
Hans Buch supplies complete gas detection solutions for industry, marine applications and infrastructure. We help assess risks, select the right technologies and integrate the system into your facility – from the initial risk assessment to commissioning and ongoing servicing.
Gas hazards arise where you least expect them
Basements and confined spaces at risk of oxygen displacement. Process facilities with NH₃, H₂S or hydrocarbons. Biogas plants with methane leaks. Refrigeration systems with F-gases. What they all have in common is that the gas is invisible – and that the consequences of failing to detect it can be fatal.
We advise on which gas types are relevant to your site and design a system that actually works in your specific environment.
Solutions from sensor to system
Fixed gas detectors form the backbone of a stationary monitoring solution. They are positioned strategically in production halls, plant rooms and other critical zones, sending continuous data to a central alarm panel or directly to your control system.
Portable multi-gas detectors complement the fixed installation and provide personal protection during inspections, repairs in confined spaces and situations where the fixed installation does not provide sufficient coverage.
The right measurement principle – catalytic, electrochemical or infrared – depends entirely on the gas and the environment. This is one of the crucial choices we help you get right.
ATEX, SIL and marine approvals
In potentially explosive atmospheres, the law requires ATEX-approved equipment. Safety instrumented systems are subject to SIL requirements. And in marine environments, classification societies have their own rules. Hans Buch supplies equipment that meets these requirements – and we help with documentation and zone classification.
We are ourselves certified to ISO 9001, ISO 14001 and ISO 45001, and this approach shapes the way we design safety-critical systems.
When should you choose each sensor technology?
| Sensor type | Typical application |
|---|---|
| Electrochemical | Toxic gases and oxygen measurement |
| Catalytic | Flammable gases |
| Infrared (IR) | CO₂ and hydrocarbons |
| PID | Volatile organic compounds (VOCs) |
