Aerothermy

The 7.5 kW air conditioner was to be loaded on command and communication military shelter. This air conditioner is connected to a control panel to enable, among other things, the selection of the mode of operation of the air conditioner (ventilation, air conditioning, etc.), and setting the temperature set point. A PC software via an RS232 link facilitates maintenance of the air conditioner.

Key features:

• Three-phase 400V 50Hz power supply,
• Noise level 60dbA,
• Refrigerating power at +49°c : 7.5kW
• Deported control panel.
