Understanding Climate Classes

All refrigeration appliances require a particular atmosphere in order to operate faultlessly. Our modern refrigerators are more energy efficient, more spacious and can preserve food better than ever.

Refrigeration is now designed not only to serve different purposes but to perform in different spaces and parts of the world under varying conditions.

This has created the requirement that manufacturers include proper labelling in the form of Minimum Energy Performance Standards (MEPS) as part of responsible manufacturing and usage for efficiency.


Climate classes dictate the temperature and humidity ranges the equipment will work best in. This allows you to purchase the best equipment for your space.

We would always recommend researching which climate class you require prior to purchasing.

  • Climate Class 3. ambient of 25°C with 60% RH.
  • Climate Class 5. ambient of 30°C with 55% RH.
  • Climate Class 5. ambient of 40°C with 40% RH.
  • N Class (temperature class) ambient of +16°C and +32°C.
  • SN Class ( extended temperature class) ambient of +10°C and +32°C.
  • ST Class (sub-tropical class) ambient of +18°C and +38°C.
  • T Class (tropical class)
Each refrigerator is designed with their climate class in mind, they will operate in different conditions. Before the equipment is given its climate class it is tested to ensure it canoperate effectively in that environment - these tests are carried out by the manufacturer in environments specially designed to mimic the climatic conditions that the equipment will be required to function in.

Climate classes are important because it allows more efficient use of the equipment. Equipment kept in environments not suited to their climate class will not run effectively and can even damage the unit as well as not preserve your stock.

It also saves on energy consumption as equipment in the wrong conditions will work harder and therefore use more electricity.

It reassures you that your equipment isn't going to fail due to overworking. Refrigeration equipment is one of the most expensive pieces of kit and repairs are not cheap.

Ensuring your equipment is properly rated will save you money and ensure you provide the best service to your customers without affecting the environment.
