VSD: DRIVING DOWN YOUR ENERGY COSTS

Over 80% of a compressor’s lifecycle cost is taken up by the energy it consumes. Moreover, the generation of compressed air can account for more than 40% of a plant’s total electricity bill. To cut your energy costs, Atlas Copco pioneered Variable Speed Drive (VSD) technology in the compressed air industry. VSD leads to major energy savings, while protecting the environment for future generations.Thanks to continual investments in this technology, Atlas Copco offers the widest range of integrated VSD compressors on the market.

Why Atlas Copco Variable Speed Drive technology?

On average 35% energy savings during fluctuations in production demand with an extensive turndown range. Integrated Elektronikon Graphic controller controls the motor speed and high efficiency frequency inverter. No wasted idling times or blow-off losses in normal operation. Atlas Copco air compressors can start/stop under full system pressure without the need to unload with special VSD motor. Eliminates peak current penalty during start-up. Minimizes system leakage due to a lower system pressure. EMC Compliance to directives (2004/108/EG).

In almost every production environment, air demand fluctuates depending on different factors such as the time of the day, week or even month. Extensive measurements and studies of compressed air demand profiles show that many compressors have substantial variations in air demand. Only 8% of all installations have a more stable air demand.

WHY DRY YOUR COMPRESSED AIR?

Untreated compressed air contains moisture, aerosols and dirt particles that can damage your air system and contaminate your end product, resulting in risk of corrosion and compressed air system leaks. Maintenance costs can far exceed air treatment costs. An air dryer is therefore essential to protect your systems and processes. The GA, GA+ and GA VSD Atlas Copco air compressors have an integrated dryer option to secure your peace of mind.

Integrated dry air

• Optimized sizing for the compressor, avoiding excessive energy consumption.
• Fit for your application.
• Controlled and monitored by theElektronikon® .
• Space-saving all-in-one solution with low installation costs.

Lowest lifecycle costs and peace of mind

• No extra installation costs.
• Saving floor space.
• Use of energy-efficient, environmentally friendly refrigerant R410A reduces operating costs and stands for zero ozone depletion.
• Heat exchanger cross-flow technology with low pressure drop, saving energy and costs.
• Zero waste of compressed air thanks tono-loss condensate drain.
• Advanced control functions ensure dry air under all circumstances and prevent freezing at low load.
• Pressure dew point of 3°C (100% relative humidity at 20°C).

Integrated purity

The optional UD⁺ filter and integrated refrigerant air dryer (IFD)   efficiently remove moisture, aerosols and dirt particles to protect your investment. The UD⁺ filter has a 40% lower pressure drop than the conventional DD⁺/PD⁺ filter combination. It saves space and reduces energy costs. Using only 1 single filter it is possible  to reach quality class 1.4.2 according to ISO 8573-1:2010.

	ISO quality class*	Dirt particle size	Water pressure dew point**	Oil concentration

*The table values reflect the maximum limits according to the ISO quality air standard (ISO 8573-1:2010). ** Water pressure dew point based on 100% RH at 20°C/68°F.

WORKPLACE: COMPRESSED AIR ATTHE POINT OF USE

With the industry-leading low noise operation and integration of air and condensate treatment equipment, the GA⁺ offers complete versatility for your production. The compressor’s integrated design allows it to be placed on the production floor, creating substantial energy savings foryour business.

Low installation costs

• The GA⁺ can operate close to the point of use – eliminating the need for a dedicated compressor room.
• The GA⁺ is delivered ready for use – minimizing production downtime and reducing installation costs.
• Filtration equipment is integrated – reducing the need for costly external piping and minimizing pressure drops. Low noise enables the above to be a reality.

Reduced energy and maintenance costs

• With less external piping, the GA⁺ minimizes pressure drop across the system which can reduce energy costs.
• The filtration system produces clean air to prevent network corrosion – minimizing energy, repair and maintenance costs.
• The GA⁺ operates at the lowest possible system pressure to reduce energy costs thanks to the Elektronikon® advanced monitoring system.

FAQ

Here are five frequently asked questions (FAQs) based on the Atlas Copco GA 30⁺-90 GA 37-90 VSD Air Compressors:

1. What is the main difference between the GA 30⁺-90 and GA 37-90 VSD series air compressors?
The GA 30⁺-90 series are fixed-speed air compressors, ideal for applications with stable air demand. In contrast, the GA 37-90 VSD series features Variable Speed Drive (VSD) technology, which automatically adjusts motor speed based on actual air demand. This makes it more suitable for applications with fluctuating loads, helping to save energy and reduce operational costs.

2. How can I ensure the efficient operation of my air compressor?
Regular maintenance is key to ensuring optimal performance. This includes periodically checking and replacing air filters, oil filters, and lubricant oil, keeping the cooling system clean, and inspecting all electrical and mechanical connections. Following the manufacturer’s maintenance schedule will help extend the lifespan of your equipment and maintain its efficiency.

3. What could cause a high-temperature alarm during air compressor operation?
A high-temperature alarm can be triggered by various factors, including excessive ambient temperature, a clogged cooler, low oil levels, a blocked oil filter, or a malfunctioning cooling fan. It is recommended to check environmental conditions, ensure the cooling system is clean, maintain proper oil levels, and inspect the related components for potential issues.

4. How do I address excessive oil consumption in my air compressor?
Excessive oil consumption may be caused by an overfilled oil level, a clogged oil return pipe, a damaged oil separator filter, or the use of incorrect lubricating oil. To resolve this, check and adjust the oil level, clean or replace the oil return pipe and oil separator filter, and ensure you are using the manufacturer-recommended lubricant.

5. What factors should I consider when purchasing a GA 30⁺-90 or GA 37-90 VSD air compressor?
When purchasing an air compressor, consider the following factors:

• Air demand: Ensure the compressor’s capacity matches your facility’s air consumption needs.

• Energy efficiency: VSD models provide better energy savings for varying load demands.

• Maintenance requirements: Choose a model with an accessible design for easy servicing.

• Installation space: Ensure there is enough room for ventilation and maintenance.

• Total cost of ownership: Consider initial costs, energy consumption, and maintenance expenses over time.
