There is a change in the air

Arctic India Engineering is going to be Desiccant Rotors International….

The process of globalisation requires a constant change. Some our high tech components/products supplied to USA, Europe, Japan, etc by our export division, Desiccant Rotors International (DRI) have gained wide acceptance abroad. In India the same products are manufactured and sold by Arctic India Engineering. To streamline and have one identity the world over for this group company, plans are on anvil to change the name from Arctic India Engineering Pvt. Ltd. to Desiccant Rotors International…..DRI

Delair the preferred option for discerning

Delair organised seminars to promote better understanding of Compressed Air Drying

…at Secunderabad

AMIS Engineering, Delair’s Dealer in Andhra Pradesh along with lIPE organised a one day workshop forthe plant and maintenance engineers. The workshop was highly interactive and extensively covered topics like the advantage / limitations and comparison of hydraulics with various type of compressors, air dryers and accessories, pneumatic circuitry elements, latest trends, etc. Mr. Naveen Zutshi, National Sales Manager, Delair presented the paper on behalf of Delair

…at TISCO, Jamshedpur
The seminar “Compressed Air Drying in Steel Plant and other Engineering Industries” organized by Delair at Jamshedpur focused on the ‘Use of Dry Compressed Air in Instrumentation and Process Application’ generated enthusiastic participation from industrial majors like TISCO.

When Moisture is Torture!

Dry, Compressed Air for Fly Ash Handling

Nearly 73% of India’s total installed power generation capacity is thermal, of which coal based generation is 90%. The utility thermal power stations, besides the several captive power plants, use bituminous and sub-bituminous coal and produce large quantities of fly ash. The process of coal combustion results in fly ash. Thermal power plants need dry, compressed air for Fly Ash conveying.

Pressure conveying system

Bulk material is conveyed by air under pressure. This system offers advantages of conveying material from one point to another or to a number of discharge points. The system is composed of a blower or a fan, rotary lock, cyclone separator, divertor, piping and fittings bag filter.

Pressure conveying system needs dry compressed air to transport dry fly ash from the surge hopper to the silo for ash storage. Here, the dry ash is mixed with the compressed air-ash mixture being conveyed through the pipeline which runs upto the storage silo where the ash is discharged and the air is released into the atmosphere after filtration. If moisture is present in the compressed air stream, the ash gets moistened, sticking to the sides of the pipeline leading to scale formation and corrosion of pipes.

Moisture Chaos

Moisture in compressed air stream leads to

- Corrosion in pipes, ash intake valves, air intake valves and other components.
- Increased downtime and maintenance costs of pneumatic controls.
- Contamination and damage at points where the compressed air comes directly in contact with sensitive materials.
- Rust and scale formation in pipelines, silos.
- Sluggish and inconsistent operation of air valves.

Malfunctioning of pneumatic shutters

Relief from Moisture :
There can be tremendous saving of energy costs if the compressed air is dried upto 2 to 5 °C PDP (Pressure Dew Point) instead of (-) 20°C, corresponding to ADP of -20°C to – 40°C respectively. For most cost effective removal of moisture from the compressed air stream, Delair engineers suggest installation of Refrigeration Type Dryers since Heatless Type Dryers use more power because of the purges process of reactivation. Delair has been able to save production and energy cost for many thermal and cement plants by installing its wide range of Refrigeration and Adsorption Compressed Air Dryers. Some of the satisfied customers who have installed Delair Dryers in their manufacturing units include:
