Vahterus is the forerunner of Plate & Shell heat exchanger technology and, like Fluid Dynamics, is a company known for its innovation.
Technology developed by Vahterus is utilized worldwide in various demanding processes including the oil, gas, chemical, process, energy and refrigeration industries.
Compact and manufactured to the highest standard, Fluid Dynamics’ Plate & Shell Heat Exchangers have at their heart a fully welded pack of circular plates in a strong, unique shell construction.
Our Plate & Shell Heat Exchangers combine the best features of both plate heat exchangers and shell & tube heat exchangers and can withstand very high pressures and both very low and very temperatures.
If you need a Plate & Shell heat exchanger contact Fluid Dynamics.
Vahterus Plate & Shell heat exchangers are always designed and manufactured according to our customer ‘s demands and to find the best thermal solution – design, sizing, customer requirements, application and any specific demands.
Our team’s extensive knowledge in heat transfer theory, laboratory testing and strong practical experience guarantees our customers the best possible heat exchanger solution while keeping the heat exchanger size, material used and costs at minimum.
Tight production control systems and automated production process enable flexible production and short delivery times. The highly skilled and trained personnel are equipped with strong practical experience allow us to guarantee reliable, consistent and durable products.
Vahterus Plate & Shell heat exchangers require only 25% of the surface compared to shell & tube heat exchangers yet they can be constructed with up to 2000 m² of heat transfer area. The compact size minimizes installation and reduces operating and maintenance costs saving energy and the environment.
Robust gasket-free construction
The gasket-free construction is durable enough for the harshest conditions, prevents maintenance issues and leakages in very high / low pressures and temperatures.
The range of the Plate & Shell family currently comprises 9 sizes with diameters ranging from 190mm to 1358mm. Plates can be produced in a wide range of materials. After pressing and cutting, the plates are welded together to form a fully welded plate pack. Flanged ports are added to carry flow in and out of the plate pack.
The fully welded plate pack is assembled into the outer shell creating a second flow path (the ‘Shell side’).
High thermal efficiency
Plate & Shell construction creates high turbulence between the plates which provides very high thermal efficiency. This allows full advantage of a compact heat transfer solution in extreme temperatures and pressures, not possible in traditional compact heat exchangers.
The openable version of our Plate & Shell Heat Exchanger offers increased flexibility of use by allowing the fully welded plate pack to be completely withdrawn from the shell for inspection or cleaning. This is achieved by the use of a flanged and bolted shell construction. The cassette type plate pack allows quick and easy removal and refitting, thus, ensuring that process downtime is kept to a minimum.
