How We Measure

We often specify cooling capacity and/or flow rate for our cooling units. This is a service we provide and an important reference point for our customers. You, as a customer, may need to adjust the cooling values to specific requirements, such as for large kitchens and restaurants.

It could also be related to requirements from third parties, such as during procurement processes. The problem is often the same. As always, there are different ways to measure. The result can easily be adjusted to the requested value.

So, what do the numbers mean?

As Sweden’s largest supplier of water dispensers, we have our own development and design for our cooling units. We can therefore control all parameters from production to lab testing, which makes a significant difference in our communication and transparency.

Cooling Capacity

We measure a cooling capacity value known as Delta-10°C.

This means that we measure the amount of water in liters that can be dispensed in one hour, without exceeding the target temperature, calculated as 10 degrees colder than the incoming water temperature.

For example, if the incoming water is 17°C, our units can cool the water to 7°C, distributed over the specified liter amount per hour. In practice, this means that our Pro2 XXL unit can deliver about 85-95 “genuine” liters per hour.

If we take an example where the incoming water is 2 degrees lower than the above (=15°C), and the customer’s requirement is that the water should be no more than 9°C when dispensed, the same unit would be able to deliver MUCH higher liter amounts. This calculation is sometimes misleadingly used as a benchmark in procurement, so compare carefully!

Flow Capacity

We also measure flow capacity. This is simply the maximum capacity of the pump, independent of the water temperature. This measurement method also has factors that significantly impact the results. Flow regulators, carbonation chambers, nozzle collectors, etc., can all influence the final result.

It is not uncommon to see flow capacity values where what is actually being requested is cooling capacity. Compare carefully and ask questions! If you’re even slightly unsure, feel free to contact us, and we’ll help guide you through the details.

Other factors affecting the measurement results include room temperature and humidity. In these cases, it is the compressor that is impacted, which can make a significant difference depending on how and where the cooler is placed.

Our Ongoing Measurements of Our Product Range

At Escowa, we have a highly skilled technical department, and we train our own technicians as well as others in the industry. We are very proud of the trust we have with some of our largest customers, who choose to send their technicians for training with us.

We also have an impressive arsenal of our own test equipment used to measure the quality and capacity of our water dispensers. Among other things, we use a temperature-controlled pressure vessel, which allows us to adjust the incoming water temperature with an accuracy of one degree.

We continuously perform our own measurements, and our goal is to be as accurate as our testing equipment allows us to be. Based on the results, we communicate correct data. As a customer, you should never have to doubt the capacity of our machines.

We know that we have a product range that we can be proud of, and we hope you get to experience the benefits of a Swedish-designed water dispenser as well.
