BOSAL - Heat Exchangers

BOSAL Energy is determined to take a leading position in the emerging renewable energy markets and provides specific heat exchanger solutions for all emerging technologies which will play an increasing role in the near future, such as Solid Oxide Fuel Cell Technology (SOFC) or Solid Oxide Electrolysers (SOEC).

These high-temperature carbon-emission-reducing technologies will allow energy to be produced with higher efficiency than any other means, at any desired scale, making them very attractive for “fuel-to-power” applications such as:

• Residential power and combined heat/power;
• Commercial power and combined heat/power;
• Distributed electricity generation for data centres, charging stations for BEV to name a few

And for “power-to-fuel” applications such as:

• Green hydrogen manufacturing
• Clean CO and ammonia production
• Syngas and synfuel production

With the purpose to produce in an environmentally friendly way basic chemicals for the industry, or store in chemicals excess green electricity from photovoltaics and wind into a chemical energy form for later use.

Beside those new disruptive fuel cell based applications, BOSAL has many years of experience in µ-Gas Turbine applications with highly effective recuperators from 30kW to 150kW, but also have provided products that were employed in other high temperature applications like steam reformers, evaporators, and condensers, whereby we can also offer tubular heat exchangers.

BOSAL’s main competitive differentiator is our offering of fully welded thin foil heat exchangers which combine high effectiveness with low back pressure in very compact design.

Our heat exchangers work according to a primary heat exchange principle through a stack of thin foils, with a proprietary design resulting in a high surface density (more than 1.2 m2/litre) and a very “organised” transfer of heat, getting as close as possible to ideal thermodynamic heat transfer. More than 12 patents have been filed during the development of these cutting-edge components, whereas we use hydroforming techniques to manufacture our proprietary corrugated foils which are stress-free and uniform in thickness, the guarantee for long-lasting durability.

Our customers state that a very low pressure drop in combination with a small volume contributes to smaller and more efficient systems with positive impact of their OPEX. In other words the cost to produce a kilowatt of  electric power is lower in case of a SOFC or µGas turbine, the electricity needed to produce a kilogram of hydrogen gas is lower.

• High heat exchangers effectiveness: we have applications with up to 95% temperature transfer from one energy stream to the other. In other words, BOSAL preserves the quality of heat in your process so that you can do more with it.
• Low back-pressure: you will need less power to feed our heat exchangers so have more power to do additional things with.
• Compact design: Our modular plate design comes in four footprints from the size of a business card to an A3-page format. We stack them to cores which contain between eight and 400 cells, which enables us to size the heat exchangers to your precise specifications… and they all have one common characteristic: they are small, resulting in less thermal loss, less insulation costs, less weight, more space for something else.
• Fully seal-tight welded assemblies: Our stainless steel/Inconel heat exchangers are fully welded with no use of seals nor gaskets. We use laser welding to achieve maximum precision and durability. Seal-tight for a lifetime.
