Flanged heaters are a cost effective way of heating liquids. Materials and watts densities are chosen based on the heated liquid or gas. The shape of the heater is chosen based on customer requirements.

Temperature controls, limiters and cables can be included for easy installation. Typical applications are hot water boilers, swimming pool heaters, constant temperature units, catering equipment etc.

Specialized in VACUUMBRAZING

Vacuum brazing process is a unique method to join parts. During the brazing process thebraze material melts and flows into a jointby 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). Vacuum brazing does not require any flux orother additives and therefore no cleaning or passivating processes are required.

BENEFITS

- Outstanding corrosion resistance- No need for post-process cleaning treatment- The most effective process to join comlex structures- Uniform heat treatment without thermal stress

Vacuum treatment ensures that brazed units do not react with the ambient gases, ensuring high quality seam. Brazing operation can be carried out not only in vacuum but also in shield gas atmosphere. All Loval vacuum furnaces can use nitrogen and the latest one also argon and hydrogen as shield gas. The latest brazing method at Loval is diffusion brazing which allows joining of componentswithoutfillermetals.

TYPICAL APPLICATIONS •Hot water boilers •Professional steam ovens •Coffeemachines •Motor homes •Engine pre-heaters •Dishwashers
