Gas heated vaporizer
A gas heated vaporizer is an essential component of industrial installations in which cryogenic liquids, such as LNG (Liquefied Natural Gas), liquid nitrogen or liquid oxygen, must be evaporated in a controlled manner. These vaporizers use hot flue gases as an external heat source to convert liquid into gas form. Thanks to this efficient and reliable method, a constant and safe gas flow can be guaranteed. This is crucial in sectors where operational continuity and process reliability have the highest priority, such as in the chemical industry, power generation, aviation and healthcare. Cryonorm offers high-quality and custom-made gas heated vaporizers that fully meet the technical requirements of your process and the specific conditions on site.
What is a gas heated vaporizer?
A gas heated vaporizer is designed to evaporate cryogenic liquids by means of heat released from hot flue gases. The heat is transferred via a heat exchanger, thereby preventing direct contact between the heating medium and the gas. This indirect heating makes the process extremely safe and efficient. Unlike electric or water bath vaporizers, a gas heated vaporizer is suitable for environments where combustion gases are already available, such as in industrial ovens, engines or turbines. The system can function completely independently from the electricity grid, ideal for locations with limited or unstable power supply.
We design a gas heated vaporizer every day tailored to factors such as evaporation capacity, available heat sources, ambient temperature and the type of cryogenic liquid. This ensures optimal integration into existing installations and maximum performance in various conditions.

In which sectors is this vaporizer used?
The applications of a gas heated vaporizer are very diverse. You will find these systems in:
- LNG distribution and storage terminals
- Industrial production processes
- Power plants and combined heat and power installations
- Petrochemical plants
- Aviation ground installations
- Remote locations without stable energy infrastructure
Wherever large quantities of gas need to be converted from cryogenic storage, the gas heated vaporizer offers a robust and efficient solution. Thanks to the modular design, the system can be adapted to the existing infrastructure. Cryonorm supplies systems worldwide that meet the strictest safety requirements and industrial standards.
The benefits of a gas heated vaporizer
A gas heated vaporizer offers multiple advantages compared to other forms of vaporization:
- Efficient heat transfer via flue gases from already existing combustion processes
- High reliability during long-term and intensive use
- Completely independent from electricity ideal for remote applications
- Widely applicable for various cryogenic media such as LNG, LOX, LIN or LAR
- Fully customisable based on your technical specifications
Cryonorm actively contributes to the design and implementation of your system. This results in a solution that is not only technically sound but also practically feasible within your organisation.
