How to cool a store during a heat wave?

The summer of 2020 was sun-drenched, with temperatures rising high. We kept our cool and made sure that our cooling units remained in great condition.

Historically hot

The heat wave in the beginning of August was one for the history books. Not in terms of length, but in terms of temperature. From 6 to 12 August, the average maximum temperature was no less than 33.5 degrees, making it the warmest week since official measurements began.

With such high temperatures, cooling is far from simple: our installations suffer from high pressure for example, because they can't release their heat outside. Fortunately, our colleagues at the stores can count on our internal cooling technicians!

Analysing and improving

Peter Basteleus, Techniques department head: "After the hot summer of 2019, we analysed the problems we faced during the heat wave. We used these findings to prepare for this summer."

Optimising all cooling units to be able to cope with a new record summer: it was not a simple task. In order to deal with the large work volume during the summer months, we also examined our organisation. In all, our branch stores have over 1,600 cooling units. With a few exceptions, they all remained at a constant temperature: mission accomplished!

Trust in our approach

In addition to the cooling units, we also examined the underlying electricity. Last year, an electric board here and there failed. Not surprisingly, when you look at the large electricity demand of a cooling unit at full capacity. This summer was scorching hot again, but the electricity didn't budge. So we rose to that challenge as well.

"We assume that temperature will rise enormously in the summers to come. However, I have complete confidence that we have the necessary knowledge and expertise to leave our customers and colleagues out in the cold", Peter decides with a wink.
