Circulation type low temperature wind tunnel

We have installed a circulating low-temperature wind tunnel to conduct performance tests of air-cooled heat exchangers and frozen oil removal tests.
It is possible to supply low-temperature air (-54°C) by injecting liquid nitrogen.
As it is a circulating type device, it is characterized by the continuous supply of low-temperature air (-54°C).
Additionally, within the test sample installation area, ducts before and after the test sample can be specially designed to match the device interface, making it possible to accommodate products of various dimensions.
