RETIREMENT
At the end of the life cycle of the refrigerant compressed air dryer, there
are some points that deserve special attention:
1. The refrigerant is to be pumped from the refrigerant system.
When pumped, the refrigerant can be regenerated and reused when
observing local regulations.
2. The compressor contains oil.
This oil is to be removed from the compressor and can be disposed of
when observing local regulations.
3. Piping and heat exchanger are made of copper.
Copper can be reused when observing local regulations.
4. The (white) isolating foam and (black) armaflex isolation is
produced environmentally friendly.
The isolating material can be disposed of when observing local
regulations.
The remaining part of the dryer can be disposed of, observing local
regulations.

3. Hazards identification
Most important hazards: Vapours are heavier thant air and can cause
suffocation by reducing oxygen available for breathing.
Specific hazards: Rapid evaporation of the liquid may cause frostbite.
4. First aid measures
General advice: Never give anything by mouth to an unconscious
person.
Inhalation: Move to fresh air. Oxygen or artificial respiration if needed.
Do not give arenaline or similar drugs.
Eye contact: Rinse thoroughly with plenty of water for at least 15
minutes and consult a physician.
Skin contact: Wash off immediately with plenty of water. Take off all
contaminated clothing immediately.
5. Fire fighting measures:
Suitible extinguishing media: any
Specific hazards: Pressure build–up
Specific methods: Cool containers / tanks with spray water.
6. Accidental release measures
Personal precautions: Evacuate personel to safe areas. Ensure
adequate ventilation. Use personal protective equipment.
Environmental precautions: Evaporates.
