Climate class - what you need to know before you buy a device

Sep 9, 2021


What is most important to you when you buy a refrigeration appliance? Dimensions? Capacity? Temperature range you can set? Type of cooling or available colours and accessories? All these parameters make up a successful purchase, but there is something else to consider before ordering the device. What do you need to know about the climate class to choose the best solutions for you? 


The climate class is one of the parameters in which the maximum conditions for the operation of a given device are determined, to be specific: the highest temperature and humidity of the room. It concerns the test room, not the device itself.

It is used to mark the conditions under which the device is tested and the parameters to which it will operate without interference (according to the PN-EN 23953-2 standard).


The room where you want to place the cooling device should also meet certain requirements. When choosing a refrigerated cabinet, counter, display case or shelving, check the temperature and humidity in the room. Also consider air conditioning and equipment that generates heat during operation (e.g. cookers, stoves, heaters and radiators, and other appliances with a aggregate). Pay attention to ventilation, windows and the amount of sunshine. It will be best if you take your measurements at different times of the year.


How is the climate class determined?


In the case of devices for commercial use that you will find in our offer, the climate class is marked with the following numbers: 

  • 3 – temperature from +10 to 25°C, relative humidity 60%;
  • 4 – temperature from +10 to 30°C, relative humidity 55%;
  • 5 – temperature from +10 to 40°C, relative humidity 40%;
  • 7 – temperature from +10 to 35°C, relative humidity 75%

What happens when the environmental conditions exceed those indicated in the climate class?


If your device is classified as class 3 and works in a room without air conditioning, where the temperature in summer is 30 °C and the humidity is 60-70%, you can expect the following:

  • the device will start to consume a much larger amount of electricity because it will not be able to effectively cool the products,
  • will not maintain the set temperature,
  • moisture will start to condense on the windows,
  • the device may be damaged.


How to choose a climate class? 


Before you buy the device, carefully analyse the conditions in the room in which it will be placed. Check: 

  • how the ventilation works (the refrigerator should not stand close to the air outlets, it may interfere with the operation of the cooling system),
  • what will be the distribution of other devices (how far will the devices that emit heat or have their own aggregates stand),
  • are there any additional factors that may increase the temperature or humidity inside (e.g. furnaces), 
  • how the air conditioning is installed (if any),
  • what is the minimum and maximum temperature and humidity in a given room.

A higher climate class often means a higher one-time purchase cost. However, this should not discourage you, as a device with a class lower than recommended will consume more electricity under wrong conditions, and in the event of a fault - you will pay for the repair.


If you want to ask our opinion before purchasing the device, please contact our Customer Service Department. You can also check the technical parameters of the devices and configure them yourself directly on our website.
