Laser-welded dimple jacket

Laser-welded dimple jacket integrated into process tanks

As laser-welded dimple jacket supplier we are specialized in the manufacturing of dimple jacketed tank and reactors plates. Dimple jacketing provides excellent heat transfer for heating or cooling the contents of your tank. We can attach dimple plates to fit the outside or underside of your tanks so steam or cooling water can heat or cool the contents of your tank.

The complete process tank wall can be manufactured out of a laser-welded dimple plate and functions as dimple jacket. Most noteworthy there is no more homogeneous tempering than demonstrably formed by a complete enclosure of the product with an entire dimple heat transfer surface as heat exchanger dimple jacket. Moreover, even with contamination or a dirt layers on these dimple plates, the U-values ​​of these heat transfer shells are only insignificantly influenced. In comparison to compact external thermal heat exchangers, favorable temperature differences result in a significantly better efficiency. At the same time, the products, especially beverages, are treated very gently. Laser-welded dimple jackets are mainly used as process tank plates such as for milk, beer and wine cooling tank plates.

The large dimple jacketed surface ensures safe process control with controlled homogeneous temperature control. Compared with double-jacket design or welded-on half-pipe coils, which occupy only about half of the surface, laser-welded dimple jacket plates are more effective and homogeneous, because they occupy the entire surface. Above all Laser-welded dimple plates have less volume and allow thinner tank walls, as well as lighter and over all cheaper tanks.

The dimple jacket design as tank cooling jacket allows the temperature control of products during other process steps. This saves a separate thermal process stage and often increases productivity and product quality.

Laser-welded dimple jacket method of operation

Individual design in measurement, shape and material allow flexible use in numerous industries and extend the normal standard. Single embossed laser-welded dimple jackets may be rolled to a cylindrical half-jacket and be clamped on to existing tanks retroactively or being welded to rings to build a tank.

Complete cylinder tanks are made from laser welded panels, of those the profile have not been blown up
then. The flow profile of the heat exchange panels will be blown up after the tank has been build, the later dimple plate tank or pressure vessel  inside is not damaged by the laser welding process. Surface treatments are generally no longer required. . Any shape of cut-outs for pipes etc. can be foreseen
