Dimple plates


Dimple plates – Heat transfer by plates instead of tubes

Each of our Dimple plates contains a process individualized design. Flexible in shape and material, it allows a complex use in many different industries. The trend to  individual design can be increasingly noticed. Hardly any manufactured heat exchanger is identical, but precisely suitable for its application. Out of the calculations or simulations, the resulting design is based on decades of experience and advanced Computational Fluid Dynamics (CFD).

Core competence and decades of experience with Dimple plates

We are mainly in tight contact with the final customer or the refrigeration company. In some cases aswell with the plant operator or the refrigeration plant builder. Each thermal dimple plate turns out to be a thermal dimple plate heat exchanger, or a laser-welded dimple jacket or pressure vessel wall.

In combination as a system, several thermal dimple plates are welded as compact heat exchange system , an ice water generating falling-film chiller, a static ice bank or an industrial ice maker. They are manufactued in a stainless steel housing to function as a closed system or they are installed submerged in an insulated stainless steel tank.

Main and unique know-how

With experience of several thousand built-in thermal dimple plates in apparatus, we are primarily focussed on the following core competences :

Analysis of pillow-plate solutions in industrial processes

In a first step, we specify the exact plant data together with the customer. We inspect the installation details, the system plans, measurement diagrams, as well as detailed design drawings. Through these insights, we answer the application requirements of any individual application or application detailed questions as such. If necessary, we also collect accurate performance and consumption data over a period of time.

Evaluation step

In a second step, our experts evaluate all collected data. Accordingly, the customer receives our assessment on his project data. Especially with regard to optimizing the efficiency of the specified dimple plate. Also with regard to operational safety and potential energy savings, we give our use case recommendations.

Solution concept and Design

As a result of our analysis, the idea of ​​the dimple plate solution concept and its design takes place. Consequently, we also look after and accompany the customer after delivery. As per our experience, there is a high need in many cases. Especially with regard to further optimization of product efficiency or operational safety. Necessarily, the mostly laser-welded dimple plates and its specification of installation is detected and successfully targeted. The main focus is on the optimal efficiency of the dimple plate (author is head of our R&D department) with respect to the guided pathes of the immersion dimple plates.

Plant and energy efficiency

Highest plant and energy efficiency are becoming increasingly important. These can only be successfully achieved, if the plant or product concept, as well as the fluid medium of the dimple plate are carefully and purposefully selected and used. In the change of numerous, alternative refrigerants, these fluids have to meet the future requirements from any ecological point of view. However, our primary task is to specify end products, which achieve high efficiency and high energy efficiency with good economy (author is head of our R&D department).
