Refrigeration / Home Appliance Components

Suction Lines and Return Tube Assemblies

Key components of refrigeration circuits functioning as heat exchangers (SLHX). Designed to maximize cooling efficiency and protect the compressor against liquid slugging.

  • Material: Copper (Cu) / Aluminum (Al)
  • Technology: Tube-in-tube exchanger
  • Leak Test: Helium method (100% of products)
  • Bending: Precision CNC 2D and 3D

The Secret Behind the Efficiency of SINTUR Assemblies

Laser Bonding

We stand out with a highly advanced process where the tube is longitudinally bonded to the capillary tube using a laser beam. This guarantees system non-separability and perfect heat transfer.

SLHX Exchanger

The integrated capillary tube subcools the liquid refrigerant, which drastically increases evaporator efficiency and reduces the energy consumption of the appliance.

Compressor Protection

Heating the return gas from the warm capillary tube ensures that only dry vapor enters the compressor, eliminating the risk of failure.

Absolute Tightness

The application of helium detection allows for the discovery of leaks thousands of times smaller than traditional water testing methods, ensuring decades of trouble-free operation.
