The Thermal Batteries are primary (non-rechargeable), single-use power sources.
Totally inert before their activation, they are storable without limitation and deliver high electrical powers.
The current range of the thermal batteries is being expanded:
(*) Exclusive ASB-Group
ASB-Group produces thermal batteries for civil and military applications, designed to meet the most extreme requirements. The thermal batteries of ASB-Group are developed according to the specific needs of the customer, which confers them a dimension of tailor-made products.
In the widening world of the power supply solutions, the Thermal Batteries feature very specific advantages:
The application range of the thermal batteries in the field of the defense is still widening, in diversity of domains and ranges of solutions:
The intrinsic characteristics of robustness, life expectancy and specific power of the thermal batteries confer them some demonstrated advantages in the following applications:
Successfully used for more than 20 years on spatial launchers, the thermal batteries are the power sources for the following applications:
Recently, ASB Group seeks to diversify into distant areas of historic areas. For this, we develop thermal batteries that may be suitable for civil applications that affect everyone every day. Energy field like oil and gas needs power sources that are able to face high operational temperatures (above 220°C). ASB Group has the technology to develop customer solution to be used up to +300°C during 3 weeks after activation.
Land mobility systems also need emergency power supplies.
This battery is capable of operating at temperatures between 150°C and 250°C, with discharge times in excess of 10 days. The advantages of this technology are as follows:
ASB's long experience in battery back-up, or in single power supplies for critical systems (Defence & Space), allows to consider applications that would require a reliable power supply in extreme conditions, and without possible maintenance:
The ASB Hermetics division was created in 1998, initially in support to the thermal battery activities. As a key internal process, this is now a strategic activity for the ASB-group, which is also dedicated to external customers, and in continuous growth.
This development is supported by our will to develop high-technology solutions in response to the specific requirements for aeronautics, space, energy, and armement industries. Our activities are focused on the design and production of hermetics parts, in small and medium series, with professionalism and efficiency.
As ASB Hermetics has the necessary competences, calculation & industrial means, and know-hows associated to various technologies, we are in position to offer you a global solution. Whatever your hermeticity issue, do not hesitate to challenge us
With its range of technological solutions, ASB Hermetics has developed numerous products for various applications:
The sealing on steel and stainless steel is a compression sealing.
Description: During the high temperature furnace run, the housing (having a higher coefficient of expansion than the glass) expands, the glass melts and fills the available space. On cooling, the glass is compressed by the housing.
Advantages: This type of sealing is mechanically very resistant, especially to thermal shocks. It is widely used in connector technology or for the manufacture of pyrotechnic bases, sensors (pressure, temperature, etc.) and battery covers.
Materials used:
The sealing on Kovar© is a tuned sealing.
Description: The case and the pin are made of a particular alloy (iron-nickel-cobalt) with a low expansion coefficient, identical to that of glass; the oxide created on the surface of the metal interacts with the glass to create a physico-chemical type bond.
Advantages: This type of sealing is traditionally used to make housings for microelectronics and optronic applications. It offers a wide range of possibilities for parts with complex shapes.

Advantages: This type of sealing is traditionally used to make housings for microelectronics and optronic applications. It offers a wide range of possibilities for parts with complex shapes.
Materials used:
Made at a lower temperature, it has the same characteristics as the so-called traditional sealants. It uses a special glass for this purpose.
Advantages: It allows the use of materials which, until now, were not or hardly used for sealing (aluminium, titanium, brass, etc.). But it can also be used on more traditional materials (stainless steel for example), making them even more mechanically efficient.
Materials used:
As titanium is a particularly reactive metal, ASB has developed a special process for sealing this type of lightweight material.
Advantages: It offers the same performance as sealing on more traditional materials while allowing the product to be lighter.
Materials used:
This technology, which is complementary to sealing, makes it possible to offer products that are resistant to higher temperatures. It can be applied to various sectors of activity such as space, aeronautics, defence, nuclear, vacuum industry, scientific research...
Advantages: This technology allows the production of ultra-resistant bushings with a wide temperature range: -260°C to 1,000°C (depending on the type of solder).

- Ceramic insulators :
- Brazing alloys :
