What is a Scroll Compressor?

A scroll air compressor, or spiral compressor, compresses air by drawing it it, trapping it, reducing the volume and discharging it at the outlet port. The scroll compressor that you see today, such as SpiralAIR, have been the result of modernised advancements in manufacturing technology, even thought the concept of a scroll compressor has been around for over 100 years.The scroll compressor is oil-free orbiting, or positive displacement compressor. The compressor has a stator spiral fixed in a housing, and a motor driven eccentric orbiting spiral.

Here's a great video about how a scroll compressor works;


What are scroll compressors used for? 

Scroll compressors are typically 100% oil-free, and are most suitable for applications in industries like research and development labs, hospitals, universities, food and beverage, dental applications, electronics and the pharmaceutical industry. They are suited to they types of industries because they are ISO 8573-1 CLASS 0 certified compressors are easy to maintain and operate, and have minimal footprint to save space in your lab or facility. Scroll compressors such as SPR eliminate the risks of oil contamination and also reliable, efficient and cost effective source of 100% clean, pure oil-free air. 

 

4 advantages of a scroll compressor:

1. Our scroll compressors are certified 100% oil-free air 

Our range of scroll or spiral compressors provide 100% pure, clean air, complying with ISO 8573-1 CLASS 0 (2010) certification. CLASS 0 means zero risk of contamination; zero risk of damaged or unsafe products; zero risk of losses from operational downtime; and zero risk of damaging your company’s hard-won professional reputation.

2. Small footprint & Extremely quiet operation 

The slow speed of the scroll compression elements ensures that the SPR scroll compressors are exceptionally quiet. SPR units are WorkPlace Air System™ compressors, making them suitable for installation in any working environment.

3. Energy efficiency 

Our SPR scroll compressors are ideal for applications where flexibility and energy efficiency are crucial. Unnecessary energy costs are avoided thanks to the automatic stop when the required working pressure is reached. The SPR multi units are equipped with multiple scroll modules. The units utilize the Variable Delivery Technology which controls the required number of modules depending on your air demand. Hence, the SpiralAIR Multi can adjust to demand fluctuations.

4. Low maintenance 

SPR scroll compressors stand for simplicity and reliability. The scroll design has a minimal number of moving parts, ensuring a long operating life with a minimum number of service interventions.

A common questions asked is why do I need an air dryer for my compressor? Typically, air compressors produce water, and although the water can be drained, there can still be aerosol and vapour droplets that are present. This is because water cannoet be compressed. Water can damage your compressor by corroding the valves, pipes and machinery controls, which will cost you time and money to resolve. In the long run, the cost of a new compressor is a small price to pay compared to the loss of production that could potentially arise due to water damage in your compressor.
