Two Stage Water Cooled Air Compressor 90 - 450 KW

WHY ELGi’s TWO STAGE OIL FREE AIR COMPRESSORS?

Class 0 oil free air

Our Two Stage Screw Compressors regularly provide oil-free air that meets ISO8573-1 class 0 oil criteria. Along with improved rotor clearances, pipes have a one-of-a-kind e-coating that consistently produces clean, oil-free air.

Indigenously designed and manufactured airends

ELGi is one of the few oil free compressor manufacturers and suppliers who have designed their own airends. Using our patented oil-free technology, the two stage compressors are designed to give the best uptime and reliability possible. ELGi's unique eta-V rotor design optimises the compressed air system by r educing pressure losses and increasing stage efficiency.

PTFE airend coating for efficiency and long-term reliability

Our airend rotors and housing are coated with PTFE-based food-grade PP to prevent corrosion and resist high temperatures of up to 250 degrees Celsius. As a result, no efficiency is lost, and long-term performance is at its peak.

Flexible design allowing for air cooled and water cooled requirements

ELGI OF series air compressors are fitted with cupronickel coolers, which have the lowest fouling factor and highest thermal efficiency of their class and are specifically intended for temperature changes of no more than 8 degrees Celsius.

Best-in-class warranty

ELGi two stage air Compressors come with Uptime Assurance. This industry-leading warranty guarantees that its products and the components for them will perform the purpose and function for which they are designed and intended for the time periods indicated when used, serviced, and maintained in accordance with ELGi's instructions and specifications. The goal of Uptime Assurance is to give clients peace of mind.

Best-in-class maintenance cost

Our Rack and Pinion capacity control system in the Two Stage water cooled Air Compressors removes the need for maintenance after over a million cycles.

Textiles

Air compressors from the OF series are necessary in the textile industry for spinning, weaving, and dyeing processes. They provide the force required to weave complicated patterns efficiently on air-jet looms and play a major role in offering Oil-Free Air Solutions For The Textile Industry. They also make it easier to operate pneumatic control systems, which regulate varied textile machinery and ensure consistent quality and production speed.

Electronics

Precision is essential in the electronics industry. Oil free screw compressors aid in the production of electronic components by supplying clean, dry compressed air for chip blowing, PCB cleaning, and precision instrumentation. Their oil-free construction eliminates contamination, protecting the sensitive electronic components and preserving the production process's integrity.

Air Separation

Air separation procedures are all about the separation of gases in the atmosphere to produce industrial gases such as oxygen, nitrogen, and argon. The oilless air compressors compress air before it is liquefied and distilled. Their oil-free functioning eliminates the possibility of contamination of the separated gases, assuring great purity and efficiency.

Food and Beverages

OF series, silent oil free air compressors in food and beverage production are used to preserve product quality and safety. They provide the power for pneumatic systems used in packing, bottling, and food processing. They deliver oil-free air, which removes the possibility of contamination while also fulfilling strict hygiene standards and eliminating any detrimental impact on the taste and quality of the final products.

Pharmaceutical Industry

Pharmaceutical manufacturing requires extreme accuracy and purity. Oil free rotary screw air compressors power important processes such as tablet coating, fermentation, and sterile packing. Their oil-free and contaminant-free output protects the integrity of pharmaceutical products while adhering to the industry's stringent regulatory and quality standards.

FREQUENTLY ASKED QUESTIONS

Are oil-free compressors quieter?

Oil-free compressors are quieter than oil-lubricated compressors because they do not have the noise associated with moving parts soaked in oil. However, noise levels might still vary depending on the compressor’s design and size.

Can oil-free air compressors achieve high pressures?

Yes, oil-free air compressors can generate high pressures, making them appropriate for a wide range of industrial and commercial applications. They are available in various sizes and capacities to meet different pressure requirements.

Are there any specific installation requirements for oil-free compressors?

The installation requirements for oil-free compressors are comparable to those for oil-lubricated compressors, but due to the sensitivity of the applications they serve, there may be additional considerations. Proper ventilation, cooling, and air quality management are critical for ensuring the compressor’s best performance and longevity.

Rotary Screw vs. Reciprocating Air Compressors

Rotary screw compressors and reciprocating compressors are the two most commonly used types of air compressors.

Evolution of Screw Air Compressors

The concept of air compressors dates back thousands of years.
