AUTOMOTIVE

The primary use of liquid nitrogen in the automotive industry is to cryoshrink various components, such as valve seats and guides, cylinder lines, bearings, etc.

Because of the size of automotive plants, the LN2 source is often hundreds of feet from the point of use. In order to insure high quality LN2 delivery, vacuum-jacketed piping is required.

SEMIFLEX bendable piping provides the most efficient transfer of LN2 from the bulk storage tank to the point of use. Systems are all vacuum-jacketed for frost-free operation.

Freeze chambers

Freeze Chambers for Valve Seats

Our Freeze Chamber for Valve Seats features apparatus for rapidly chilling work pieces as they are delivered to an assembly line using cryogenic fluid. This Freeze Chamber is suitable for fast moving assembly lines and enables the efficient use of cryogens such as liquid nitrogen.

The flow of cryogen is controlled and stabilized, so that cryogen is not wasted. Build up of condensation and frost, which could clog the apparatus and shut down the assembly line, is avoided. Moreover, the cooling system is readily turned off and purged if a longer assembly time shutdown is required.

Freeze Chambers for Cylinder Liners

Our Freeze Chamber for Cylinder Liners provides the chilling and shrinking of work pieces being conveyed to a workstation on an assembly line. This method provides an efficient use of cryogen. The cryogen produced by the spray is used for the pre-cooling process after it has been used to chill the work pieces in the cooling stage.

The chilling chamber is configured so that the cryogen flows by gravity with no need of mechanical pumping and provides control over undesirable vapour condensation and frost formation.
