Brazed Heat Exchangers
Compact solution with high thermal performance
A brazed heat exchanger is a type of heat exchanger that is generally compact and offers high thermal efficiency. These exchangers are manufactured by melting several metal plates at high temperature using a special brazing material. The brazing creates a leak-proof bond between the plates, ensuring the integration and durability of the exchanger.
