Centrifugation is an exothermic process in which heat is produced by friction with the air in the centrifuge chamber and the different parts of the rotor. This heat depends on multiple factors such as the type of rotor or its speed. Therefore, centrifugation cycles can be affected by temperature changes.

Centrifuges made by Ortoalresa are designed to minimize temperature increase inside the chamber by means of three different systems:

In the case of non-refrigerated centrifuges by using a forced ventilation system to remove the heat from the centrifuge chamber and suck in ambient temperature air.

In refrigerated centrifuges: Using a powerful refrigeration system that reduces the increase of temperature to the value defined by the user.

Our refrigerated centrifuges are designed to maintain the desired temperature at all times. For this purpose, the first system they have is a pre-cooling programme, by which the user can cool the chamber and accessories before adding the samples. In addition, there is a refrigeration system which will ensure that the equipment at maximum speed will maintain at least 4°C.

Temperature stability is the most important parameter. Therefore, temperature control of the equipment will minimise deviations, acting on the cooling system to maintain a stable temperature. At the end of the process, it is indispensable to maintain the working temperature, therefore our refrigerated equipment will maintain this temperature up to 8 hours after the end of the cycle.

Increased temperature in the chamber is indispensable in some industrial processes in which to facilitate sample separation, in these cases heating is required, such as the case of oil products in order to determine sediments and dairy products to determine fat. For these cases, we have heated equipment that can reach up to 80°C. The temperature control is also highly precise, ensuring it is maintained constant throughout the whole process.
