How EDEKA prevents outages and improves product presentation at the same time

🥇 How EDEKA prevents outages – honest customer feedback – what do 365 days of molecular filters achieve* ?

An exciting track record. How we modernize new and existing supermarkets together with JBG Deutschland GmbH:

In the southwest of Germany, the climate in the summer months can be tropical ☀️🏝. This leads to the usual challenges in supermarkets and the refrigeration units used there, such as frozen evaporators, snow and ice forming on surfaces, unattractive product presentations and, in the worst case, operational disruptions or failures as well as loss of sales and goods. This is followed by correspondingly unscheduled service calls and the understandable dissatisfaction of all involved.

Do you recognize yourself? Don’t worry. This is what happens to many, regardless of which equipment is used. The most common reason for all these challenges: Exposure to excess moisture. 💦

But there is good news: by using our molecular filter, this is exactly what can be controlled, and it is scientifically proven. Philipp Drass, CTO and authorised signatory, from JBG Deutschland GmbH wanted to see this for himself. After more than a year of successful cooperation and several joint projects, the following results emerge:

⚙️
72% fewer operational downtimes ensure reliable equipment operation as well as the sale of goods and thus avoid additional service costs.

🌱
43% lower average defrosting times save energy costs and reduce CO2 emissions

💶
Significantly less ice and snow formation on products and surfaces ensures saleability and turnover through attractive product presentation

😃
Increased customer satisfaction due to reliable product availability and improved operational safety

Regenerative processes for humidity control

Adsorption and desorption processes always run simultaneously until a state of equilibrium resulting from the ambient conditions has been reached. Due to temperature and pressure differences, this equilibrium can be shifted more strongly in the direction of adsorption or desorption. The sorption potential of the respective system is often represented in diagrams showing the energy potential of a molecule at a distance from the surface. Curves are composed of repulsive and attractive interactions and depend on the molecule as well as the surface geometry; these can be determined, for example, via quantum chemical calculations and molecular dynamics simulations.

You can clearly see how the use of our molecular filter affects the overall performance of the cooling system. Above in orange you can see the relative humidity, which regularly reached 100% before installation and thus led to unwanted condensation. Below you can see the temperature in blue, which showed a much smaller fluctuation range after installation. More stable temperatures lead to better product quality and lower loads on the compressor.

Humidity control changes everything!
