A great atmospheric concentration can cause anesthetic effects combined with loss of consciousness. Long expositions can cause abnor-
mal heart rhytm and even sudden death.
More elevate concentrations can cause asphyxia for reduced oxygen content in the air.

Splashes of sprayed refrigerant can cause frost burns. It is unlikely tobe dangerous due to skin absorption; Prolonged and repeated contact
may cause removal of skin fat, dryness and dermatitis.

Highly unlikely but can cause frost burns.
The atmospheric refrigerant concentration has to be minimum reduced (lower then overmentioned professional exposition limit). Be infor-
med that the steam is havier then air so high concentrations can stay near the ground, where the general ventilation is low, is suggested to
ensure an adequate ventilation in order to avoid it.

All the models are provided with a BLDC hermetic compressor (with brushless permanents magnets motor) rotary or scroll type, suitable
for functioning with R410a refrigerant.
Each compressor is installed on a rubber-type vibration dampers and are equipped with:
• Oil carter, where the crankcase heater is installed (only Scroll);
• Thermistor included protection for the overloads;
• Polyester oil charge.
The compressor’s terminal board has IP54 protection. Starts and stops of compressors are directly managed by the unit controller which in
this way modulates the cooling capacity. For rotary type compressors an equalization pressure valve is provided.

The modular structure of this equipment is made up of press-formed section in galvanized sheet elements painted with a RAL 9004 epoxy
powder cycle. The elements are assembled together to make up a sturdy frame, capable of supporting units parts and to sustain strain
which may derive from unit handling and operation. The devices are arranged inside the frame in a way that they are easy to reach from
the front, to make necessary handling during unit operation and easier and more safety maintenance.

Thanks to the double coil (Freecooling water and Direct Expansion) the unit provides the highest saving match with full availability of the
DX solution.
The usage of Free cooling coil and the BLDC Inverter compressor allows maximizing the saving in mixed mode operation, so whenever the
freecooling is not able to fully take the load the compressors can work just to complete the missing cooling needs.
Therefore Emicon DXI-HF can provide extremely high energy saving granting the highest availability of the application.
