Advantage

Technical advantages - Screw compressor

 

Exceptional oil - free air

The Class 0 series compressors, with ISO 8573 - 1 classification, can help you reliably avoid risks of contamination, unsafe products, or losses caused by operational disruptions.

 

Energy savings of up to 35%

With a highly efficient design. Save more energy by using our Variable Speed Drive (VSD), energy recovery function, and zero - energy - consumption MD dryer.

 

Quick & easy setup

A plug - and - play unit that includes an integrated dryer, Variable Speed Drive (VSD), and energy recovery system. It ensures easy installation, low cost, and fast startup.

 

 

Higher reliability

Sixty years of innovation and experience, and a large customer base. Long - lasting service life is provided by high - quality components designed by Atlas Copco: stainless - steel coolers, AGMA A5/DIN 5 gears, and a new inverter drive system. Each machine undergoes strict testing to ensure reliable quality.

 

Global presence - Localized service

Our after - sales product portfolio can flexibly meet your needs, ensuring that your compressed air equipment achieves very high availability and reliability at the lowest possible operating costs.

 

Meeting higher quality standards in the food and beverage industry

Our oil - free production facilities have been ISO 22000 - accredited. This food safety management system applies to all our Z - type Class 0 oil - free screw air compressors, as well as the associated dryers and filters.

 

energy conservation

Designed specifically for energy saving

The components of our OFA/OFW oil-free screw air compressor series are all independently and meticulously designed. This minimizes losses and pressure drops to an extremely low level, helping to create a highly efficient compressor system.

Our oil-free compressors are also Class 0 certified, delivering extremely high air purity at a very low total cost of ownership. Our screw technology ensures you get a reliable and highly efficient compressor.

 

Variable Speed Drive Energy Saving Statistics

Energy costs account for more than 80% of the total life-cycle cost of a compressor.The cost of producing compressed air represents over 40% of a plant’s total electricity bill. To help you reduce power consumption, we have adopted Variable Speed Drive (VSD) technology in the compressed air industry.

Atlas Copco’s VSD technology automatically adjusts motor speed to closely match air demand, achieving energy savings of up to 35%.

 

Energy Recovery

Turn your compressor into an energy source. Our water-cooled screw compressors can be equipped with an energy recovery system, helping you achieve low-carbon economy targets.

Up to 94% of electrical energy is converted into heat of compression. Without energy recovery, this heat would be lost to the atmosphere. Our energy recovery system uses this heat to warm water for sanitary use, heating, or process applications.

 

Smart Technology for Energy Saving

Our compressor monitoring system uses advanced control algorithms to maximize energy efficiency. The Delayed Second Stop function uses air demand data to stop the compressor when possible. Dual pressure bands reduce system pressure during periods such as weekends and night shifts.

Our Elektronikon® controller is the brain of the compressor, collecting data to deliver outstanding energy efficiency.

 

 

Monitor Your System

It is essential to keep track of your compressed air system status. You can easily connect the controller to a mobile device.

The system supports remote monitoring over a secure network. This monitoring solution not only helps you save costs but also prevents downtime and production losses.。

 

Excellence as Standard

VSD / Excellence as Standard

 

Our OFA/OFW VSD compressors are among the finest oil-free compressors on the market.Designed for energy efficiency, reliability and easy maintenance, the OFA/OFW 15–750 VSD range delivers outstanding oil-free air solutions tailored to your application.
