Vacuum Brazing Elements

Info & Product Examples

Vacuum brazing process is a unique method to join parts. During the brazing process the braze material melts and flows into a joint by capillary force, creating a gas-tight seal. Brazing temperatures are between 900 – 1200 degrees under vacuum of one millionth of atmospheric pressure (<0,001 mbar).

Information about Vacuum Brazing

Our sister company Loval has several demanding product groups and customer segments where vacuum brazing with different stainless steel grades and brazing filler metals is the preferred brazing method. Highly developed vacuum brazing technology is the special strenght for Loval.

Major advantages with vacuum brazing include unchanged structure of the brazed units, good mechanical strenght of the brazed seam, corrosion resistance and cleanliness. Vacuum brazing also enables uniform quality of brazed seams.

Vacuum brazing does not require any flux or other additives and therefore no cleaning or passivating processes are required. Vacuum treatment ensures that brazed units do not react with the ambient gases, ensuring high quality seam.

Vacuum technology enables brazing of the most demanding assemblies. Vacuum brazing is a popular method in space and aviation technology and other clinically demanding applications, including vending machines.

Our siser company, Loval designs and produces a wide range of pipe heat exchangers for various heat transfer applications. Loval Pipe Heat Exhanger is a combination of different pipe diameters and connectors. Dimensioning is based on required power and flow rate. Materials can be chosen from unalloyed and alloyed steels.

Plate heat exchangers HPA-52A are especially designed as condensers or evaporators for heat pumps. High quality finishing and tightness are crucial for this kind of products. Loval vacuum brazed plate heat exchangers are of a very high quality and among the top products on the market.

Our purely stainless vacuum brazed construction means outstanding corrosion resistance. Tailored solutions e.g. manifolds for coffee machines made to measure guarantee the best results for everyday use.
