Induction brazing solutions for HVAC

Imagine you improve your productive efficiency and product quality.

Automation, quality and safety

If you need to automate brazing, you can integrate our induction equipment into your machine, or we can design a complete system according to your needs. Contact us to discover the feasibility of the process.

In the HVAC industry, a variety of components are brazed together to form assemblies and systems for heating, ventilation, air conditioning and refrigeration applications. Some commonly used elements are heat exchangers, solenoid valves and heat pump components.

Induction brazing enables efficient production, contributing to streamlined manufacturing processes, consistent quality without oxidation (under controlled atmosphere), and improved overall system performance. Its automation increases productivity, making it a valuable asset in the HVAC industry. In addition, induction brazing is safer and more suitable for heat-sensitive environments than the use of torches and gas, increasing the efficiency and safety of HVAC projects.

Customer reference projects

Automated induction brazing solution of plate heat exchangers

This solution increases production by automating the brazing of a wide range of plate heat exchangers. Various materials such as stainless steel and copper in connection tubes can be brazed.

The keys to this innovative project are the use of artificial vision to precisely identify the areas to be brazed; the coordination of robots; and the use of controlled Nitrogen and Hydrogen gases in atmosphere for a high-quality finish.

Automated induction brazing solution for solenoid valves under controlled atmosphere

The aim of this solution is to increase productivity of the existing process in the minimum layout and to reduce the maintenance operations.

It is a compact high precision automated brazing machine under controlled atmosphere with Nitrogen and Hydrogen gases with ring filler material.

The design is based on a 4-position rotary indexing table machine for tool change operations and double positions


Pure copper 3D printed inductors

Quality and expenses reduction.

Additive manufacturing (AM) is the key to achieving full coil adaptation for your heated parts. With pure copper 3D inductors, the number of changeovers is reduced due to the extraordinary service life of the coils, up to 400% in certain applications.

Patented by GH.
