Silence and Purity
The scroll compressor is known for quiet operation and air purity. Inside its small heart, two spirals move in precise motion-one stays still while the other goes around in a circle pulling in air, slowly squeezing it, then letting it out free of oil and dirt.
They talk in hospitals, they purr in labs, guarding places where work is done to make things perfect and not even a small amount of oil can get in the way. Low power use, low care needs, long life span: they are a softer more green choice. For those who want clean safe air our oil-free spiral compressor is both quiet and strong.
Introduction
Here's a complete guide to oil-free scroll compressors. These little gems of technology are designed to deliver 100% pure, clean air that meets stringent compressed air quality standards, making them particularly useful in certain industries where freedom from contaminants is a must. Find out all about them, from their operating principles to their applications and benefits.
What is a scroll compressor?
First things first, a definition. Broadly speaking, a scroll compressor is a type of positive displacement compressor widely used in air conditioning and refrigeration systems, heat pumps and cars. It works by compressing air or gas internally using two spiral-shaped scrolls. One of the spirals remains stationary while the other moves in an orbit, taking in air at the inlet, compressing it and releasing it at the outlet.
Our range of scroll compressors is known to be oil-free, compact and relatively quiet compared with other types of compressor, making it suitable for sensitive environments such as dental surgeries.
How does a scroll compressor work?
A scroll compressor works by using two spirals to compress the air and increase its pressure. Here is a step-by-step description of the process:
1. Inlet phase: Air enters the compressor through the inlet.
2. Compression phase: The orbiting volute moves in a circular motion, trapping the air between the two volutes and progressively compressing it as it approaches the centre.
3. Discharge phase: The compressed air is released through the outlet.
These stages correspond mainly to the operation of oil-free ranges.
Benefits of oil-free scroll compressors
Oil-free scroll compressors have many advantages:
- Energy and cost savings, due to low energy and operating costs.
- Carbon footprint is much smaller since there is no oil used in the machine.
- Long life-cycle: the machines are robust and designed with a minimum of moving parts.
- Low noise levels comparable to a quiet office environment, ideal for noise-sensitive applications.
- Lower upkeep costs: they are said to be simple and efficient in design, thereby lowering upkeep costs and downtimes.
For which applications?
Oil-free scroll compressors are commonly used in industries that require a clean, reliable air supply, such as laboratories, food and beverage manufacturing, research facilities and hospitals.
Comparing scroll compressors to other types
Why go for an oil-free scroll compressor rather than a piston equivalent for instance?
Scroll compressors have lower maintenance costs and requirements due to the reduced number of moving parts, and are more energy efficient. They are also more discreet.
Oil-free reciprocating compressors, on the other hand, take up more space, have a large number of moving parts and are subject to high levels of vibration. They will also have a higher noise level and a higher operating temperature, hence the need for adequate cooling and ventilation.
Of course, their respective usefulness and benefits will make them more suitable for certain types of activity. For example, oil-free reciprocating compressors will be suitable for high-demand applications.
Choosing the right oil-free scroll compressor
Here are five factors that will help you choose the right solution:
- Consider size and flow requirements, air quality standards, noise sensitivity, and maintenance needs when choosing an oil-free scroll compressor.
- Determine the capacity needed for the application.
- Make sure it meets the required standard of purity levels for air.
- If in a noise-sensitive environment, select one with low noise levels.
- Choose one that has minimal maintenance to operate.
Conclusion
