Problems

A major problem in compressed air systems is the presence of water, dust particles, oil (lubricated air compressors introduce oil particles) and solid contaminants, which can adversely affect air quality.

Moisture in compressed air may change the colour of the tablet coating
There should not be dust during the powder coating process
Moisture can react with chemicals
Moisture results in blisters on tablets
Moisture may result in breakage of tablets

If moisture-laden compressed air is used through pneumatic tools and machines, it may lead to the following problems :

Malfunctioning of pneumatic tools and machines
Sluggish and inconsistent operation of valves and cylinder
Corrosion in pipelines, cylinders and other components
Increase in downtime
Increase in maintenance cost of pneumatic machines/tools/controls.
Freezing in exposed lines during cold weather.

The majority of pharmaceutical products are highly hygroscopic and tend to suffer physical, enzymatic, microbiological, and biochemical deterioration after coming in contact with moisture-laden compressed air.
Containers require reliable clean-out and evacuation to meet stringent quality standards.

Solution

Delair offers a wide range of refrigeration and adsorption dryers that remove water/moisture, dust particles, oil (oil particles are introduced by lubricated air compressors), and solid contaminants from compressed air.

The Delair Solution

Delair Dryer operates on the method of cooling the air to a near freezing point to remove the moisture and reheat it to approximately 10°C below the incoming compressed air temperature at nominal conditions.

Delair Adsorption dryer

The Dryer is based on the principle of heatless regeneration and the physical properties of the desiccant to adsorb and desorb water vapour. It uses the pressure swing principle / purge air to regenerate the desiccant bed.
