Glass Manufacturers
Though you might not realise it, dry compressed air affects every unit of glass manufacturing.
Use of Compressed Air in the Glass Industry
Compressed air power pneumatic machines used in glass manufacturing units.
- Forming machine
- Double edge machine
- Sheet glass trolley
- Forvet – Drilling machine
- Water jet machine
Units where compressed-powered pneumatic machines are used:
- Hardening plant
- Glass designing unit
- Machining center
- Glass cutting plant
- Turning center
Applications
- Glass blowing
- Blending
- Stationery transfer device
- Cooling
- Conveying
- Clamping
- Molding
- Mixing
- Cleaning
Problems
A major problem in compressed air systems is the presence of water, dust particles, oil (oil particles are introduced by lubricated air compressors), and solid contaminants, which can adversely affect air quality.
If the contaminated compressed air is used through pneumatic tools and machines, then there will be 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
Moisture in compressed air also leads to problems such as:
- Low-level glass consistency and homogeneity, as moisture pollutes the glass
- Uneven/poor toughening processing
- Loss of strength/fogging of glass
- Poor quality of glass leads to an increase in wastage
Solution
Remove moisture/water, dust particles, oil (lubricated air compressors introduce oil particles), and solid contaminants from compressed air.
The Delair Solution
Delair offers a wide range of refrigeration and adsorption dryers that remove 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 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.
Filters
Delair also offers Pre Filters and Oil Filters, which remove dust particles, oil particles and other types of solid contaminants present in dry air.
Frequently Asked Questions
1. Where is compressed air used in glass manufacturing?
Compressed air is used across several areas of glass production. It can power forming and drilling equipment and support processes such as glass blowing, conveying, clamping, cooling, molding, mixing, blending, and cleaning. This makes a reliable air supply important for day-to-day plant operations.
2. Why does a glass forming machine need a reliable air supply?
A compressed air glass forming machine depends on pneumatic components to carry out repeated movements during production. If the air supply is unstable or contaminated, valves and cylinders may not operate properly, which can affect equipment performance and interrupt production.
3. How can moisture in compressed air affect glass quality?
Moisture can interfere with glass processing and may lead to problems such as inconsistent glass homogeneity, uneven toughening, fogging, and reduced glass strength. Controlling moisture is therefore an important part of maintaining consistent production quality.
4. What does Delair offer for compressed air treatment in glass plants?
Delair provides industrial air dryers for glass manufacturing, including refrigeration and adsorption dryers, along with pre-filters ,Fine Filters and oil filters. The dryers help remove moisture from compressed air, while the filters help remove oil, dust, and other solid contaminants before the air is used in production.
