Though you might not realize it, dry compressed air affects each and every unit in PET bottle manufacturing.
Use of Compressed Air in PET Bottle Manufacturing
Mold Press Powering
Blowing work piece from production molds
Conveying plastic pellets
In PET bottle manufacturing units, generally following compressed air powered pneumatic Systems are used :
Pneumatic Control and Actuators
A major problem in compressed air systems is the presence of water, dust particles, oil (oils particles are introduced by lubricated air compressors) and solid contaminants which can adversely affect air quality.
If the contaminated compressed air will be used through pneumatic tools and machines then there will be following problems :
Malfunctioning of pneumatic tools and machines
Sluggish and inconsistent operation of valves and cylinder
Corrosion in pipe lines, cylinder and other components
Increase in downtime
Increase in maintenance cost of pneumatic machines / tools / controls.
Freezing in exposed lines during cold weather.
Moisture in compressed air also leads to problems like :
Loss of clarity i.e clouding of PET bottles / containers
Loss of strength of PET bottles / containers
Contamination of PET resin
Internal bubbles / pockmarks in the bottles / containers
Dry and uncontaminated compressed air is must for PET blow molding process.
The Delair Solution
Remove water, dust particles, oil (oils particles are introduced by lubricated air compressors) and solid contaminants from compressed air.
Delair offers wide range of refrigeration dryer and adsorption dryers which removed water / moisture from compressed air.
Delair refrigeration dryers
This dryer operates on the method of cooling the air to near freezing point to remove the moisture and reheating it to approximately 10°C below the incoming compressed air temperature at nominal conditions.
Delair Adsorption dryer
The dryers is based on the principle of heatless regeneration and the physical properties of their desiccant to adsorb and desorb the water vapour, It uses pressure swing principle / purge air to regenerate the desiccant bed.
Delair also offers Pre Filters and Oil Filters which removes dust particles, oil particles and other types of solid contaminated present in dry air.
