Brazing solutions specifically developed for the refrigeration industry

Thessco SAS has long been at the forefront of innovation in brazing technology for both industrial and commercial refrigeration. Our alloys, entirely manufactured in house, are designed to ensure superior performance and reliability in the cooling and HVAC sectors. Our wide range of brazing solutions is engineered to improve the efficiency and durability of the equipment on which they are used.

Copper-Phosphorus and Copper-Phosphorus-Silver Alloys

These alloys significantly reduce oxide formation, enhancing the joint’s mechanical strength while ensuring reliability and durability. The addition of silver, along with phosphorus, further improves the mechanical performance of the joint.

  • Connections:  Copper to Copper and Copper to Brass
  • Available Formats:  Bare Rods, Wires (coils and spools), Rings, Preforms
  • Recommended Flux:  Standard and boric acid free fluxes.  Available in paste or powder

Silver-Based Alloys

These alloys are selected for their resistance to corrosion and high temperatures, making them ideal for refrigeration systems. The rods coated with flux reduce the need for post-brazing cleaning, simplifying and accelerating production processes, available in different ratio based on customer needs.

  • Connections:  Copper to Brass, Copper to Steel and Copper to Stainless Steel
  • Available Formats:  Bare Rods, Flux Coated Rods, Wires (coils and spools), Rings, Preforms
  • Recommended Flux:  Standard and boric acid free fluxes.  Available in paste or powder

Rings and Preforms

In order to meet the needs of the market, increasingly oriented towards the efficiency of production processes with automation, we are able to create, rings, preforms, pieces of wire, discs, shims. The latter include forks, lengths of wire, discs, plates, shears and bends. Rings are available with overlapping or non-overlapping ends, in single-turn or multi-turn. For larger diameters they are packaged and supplied on tubes.

Aluminium-Based Brazing Alloys
With the increasing use of aluminium in HVAC systems due to its light weight and excellent thermal conductivity, aluminium-based alloys have become essential. These are specifically formulated to join aluminium parts, which is particularly challenging due to aluminium’s high affinity for oxygen, as well as for aluminium-to-copper joints respective alloys.

  • Connections:  Aluminium to Aluminium, Aluminium to Copper
  • Available Formats:  Bare Rods, Flux Cored Rods, Wires (coils and spools), Rings, Preforms
  • Recommended Flux:  Standard corrosive and non-corrosive.  Available in paste or powder

Fluxes
The purpose of flux is to eliminate any oxides present on the base and filler materials, improving wettability and protecting the brazed joint from further oxidation. Our range of fluxes, CMR compliant, has eliminated toxic components while simultaneously enhancing brazing quality.

Competitive Advantages

  • We are manufacturers, not distributors—thanks to our in-house foundry, we produce all alloys ourselves.
  • Our CuP and CuPAg alloys technology, provide a non-sparkling effect and a porosity-free, cleaner brazing process.
  • Our fluxes, free from toxic components, are environmentally friendly and improve brazing quality.
  • We provide tailored solutions for each customer’s internal processes, along with dedicated technical support.
