heiserTEC – High-Pressure Systems for Fire Protection and Rescue Applications

Fire Protection & Rescue

When safety matters, precision matters most.

heiserTEC develops high-pressure cylinders and systems that save lives –
for fire suppression, breathing-air supply, and emergency use in aviation.

Maximum Safety for Critical Missions

From firefighting to evacuation and breathing-air systems,
our high-pressure solutions are designed to perform reliably under the toughest conditions.
heiserTEC stands for uncompromising quality, verified safety, and long-lasting performance – made in Austria.

Breathing-Air Systems for First Responders

In rescue and firefighting operations, clean breathing air is essential.
Our Type 1 steel cylinders are purpose-built for breathing apparatus, ensuring outstanding pressure stability,
durability, and purity – certified to international safety standards.
Reliable protection when every second counts.

Fire Suppression Systems with High-Pressure Technology

heiserTEC cylinders are integral to modern stationary and mobile fire suppression systems.
They store and release extinguishing gases safely and efficiently –
in industrial facilities, data centers, and transport environments.
Engineered for multiple extinguishing agents and system sizes.

Aviation Breathing-Air Cylinders

Aviation demands absolute reliability and lightweight durability.
Our cylinders for onboard breathing-air systems deliver maximum strength and precision,
tested to the world’s most rigorous aerospace standards.
Safety that flies.
