The cryogenics segment is developing dynamically and in order to remain among the premium suppliers of cryogenic turbo-machines, we are forced to invest in both innovation and development of new machines, and of course in the method of production, assembly and subsequently testing equipment.
When the company was founded in 2022, we used only basic measuring elements for testing our first machines, where regulation was carried out exclusively manually and a simple data logger was used for recording. Since all machines manufactured by us are thoroughly tested before being handed over to the customer, we are constantly working on improving the testing process.
Currently, we perform all tests on a PLC-controlled test facility with recording and immediate data evaluation, where the PLC we developed controls both the turbo-machine and the valve system, simulating operating conditions as they will be in real operation (gradual start-up and loading of the machine, regulation of bearing and cooling gas, gradual shutdown), or even emergency conditions (failures of individual subsystems, blackout, etc.). We record several times more values than before and use these for further innovations.
At the same time, we are preparing further modernization of the test facility so that we can switch from tests with clean, dry air at ambient temperature to tests with evaporated nitrogen and a controllable inlet temperature from normal conditions to approximately -180 °C. Thanks to this, it will be possible to simulate the behavior of machines under cryogenic conditions in which the machines will actually operate without the risk of residual moisture freezing at very low temperatures. Continuous modernization allows us to validate the validity of the computational thermal model. Thanks to the analysis of this data, a robust mathematical model is gradually created for predicting the thermal load of machines, which can then be used in the design of new machines and allows us to achieve better parameters, reliability and service life of machines.
