Kelvion has refined the K°Bloc fully-welded plate heat exchanger to further enhance its reliability and efficiency.

Designed and made in Germany, K°Bloc plays a leading role in Kelvion’s package of sustainable solutions, working across a broad range of liquids, temperatures and pressures.

It is ideally suited to the demands of the oil and gas, chemical and petrochemical industries for separating mixtures of oil, water and solids.

K°Bloc is the result of decades of experience with demanding applications, more than 30 years of welded plate heat exchanger expertise and a commitment to continuous product improvement.  

It is available in various materials and different plate corrugations.and is suitable for high temperature and pressure process applications up to 50 barg and 400°C. 

The K°Bloc frame consists of four columns, top and bottom heads and four side panels. These side panels can be detached to allow free access for cleaning the plate package.

Individual plates are welded alternately on the two longitudinal sides and at the corners. There are two pressure-resistant channels separated from one another inside the unit.

The plate pack is installed between the four columns, four bolted panels and the top/bottom head plates, thereby forming a compact plate heat exchanger with two circuits. In the plate pack, the medium flows in a cross flow direction. The entire unit consists of a counter-current cross flow arrangement.

In addition, the heat transfer plates are corrugated to induce high turbulence and minimize fouling. The turbulent flow creates high shear stress on the walls, which literally scrubs deposits and fouling from the heat transfer surface. This is known as the ‘self-cleaning effect’.

Two different plate corrugations are available. Chevron corrugation enables effective heat transfer, while double dimple corrugation is the first choice for highly viscous or solid-containing media, as well as for vacuum applications.
