The fresh air passes through the front filter while entering the device, then the last filter at the exit of the device and lastly through the hepa filter at the entrance of sterile environment and thus air filtering process is executed at a very high level.

Cooling cycle is designed by using two different circuits and two separate compressors. For cooling, capacity control is implemented by using the hot gas bypass regulator on the first compressor that steps in. In the gas circuits, refrigerant that does not damage ozone layer is used as cooling fluid.

Mediline series devices have the control equipments that can measure the values of temperature, humidity, filter and pressure within the sterile environment and keep these values under control. Whenever Mediline device is shut off for any reason, the spring return dampers get closed and the entrance of uncontrolled air into the environment is obscured. It enables the performance of aseptic and septic operations and control of positive and negative pressure in order not to be affected by the indications caused by pathogens. Main power and control panel, in which automation and power information is gathered, are located within the same body as the device however completely isolated from the device. Mediline Package Hygienic AHU has a very low level of noise by the help of the body structure and the thickness of the isolation. It does not cause any noise pollution between its own environment and other spaces.
