Air Receiver

What is an air receiver?
An air receiver, sometimes referred to as a compressed air tank, is an integral part of any compressed air system. The main purpose of this is to act as temporary storage to accommodate the peaks of demand from your system and to optimize the running efficiency of your plant.

How to properly size air receivers?

Minimizing pressure fluctuations/drops

An air receiver can be used to minimize pressure fluctuations that could have an impact on the production process and the quality of your end product. Selecting the right air tank for your compressor requires you to be mindful of two values: your compressor's output pressure and what your application needs at the point of use. Note that the compressed air stored in your air receiver is only useful as long as its pressure is sufficient for the process which uses it. This is why it is important to consider the duration (in minutes) that the air receiver can supply air at the necessary pressure for your end-user / equipment.

Meeting short term peak air demands

If the demand for compressed air changes drastically throughout the day, it is important to account for the spikes in the demand to ensure the system pressure does not drop below an acceptable level. An air receiver provides storage to meet short term peak air demands that the compressor cannot meet. Depending on the time of day, the shift pattern or even unusual demand (e.g. occasional use of a sandblaster or an abrasive media blaster), your air requirement may vary. It is important to fully understand the application and the amount of CFM or liters/second of air required, as well as the expected peaks of your system, as it dictates what flow of compressed air is needed to avoid shortages for any part of your process.

Energy considerations

Using an air receiver can help reduce energy consumption of your compressed air system by enabling load/unload (fixed speed) compressors to operate on a longer cycle and with tighter pressure bands. Having properly sized tank and more air than is required will reduce the potential of trim compressor starting up to meet increased flow demand, which can have substantial savings on your energy consumption. This will also prevent pressure fluctuation and frequent motor starts, while providing steady pressure and extending the life of the compressor.

Safety considerations

If needed, an air receiver will provide a supply of air to enable production processes and systems to be safely shutdown in an emergency situation.

Refrigeration Air dryer

During compressed air production, humidity contained in the atmospheric air is converted into a condensate. In order to prevent corrosion of compressed air lines and wear of connected devices, it is necessary to remove condensed humidity from compressed air as quickly as possible. The most common and fastest way to remove condensation from compressed air is connecting a compressed air refrigerant dryer directly to a compressors.

Dew point
Dew point level depends on the operating conditions in a compressor station. Standard dew point level of Sunwin refrigeration dryers is +3°C.

Improved air quality
Using an air dryer, the air quality improves and thus the final product quality increases. Productivity is increased and maintenance costs are lower.

Air Treatment Solution
Air treatment has become a necessity when compressing air today in terms of operating costs and increased production efficiency. Refrigerated compressed air dryers such as the Sunwin are the preferred solution thanks to an efficient and simple technology. With an air dryer, water from the air condenses and can be removed.

Oil Free Scroll Compressor

Elang oil-free scroll air compressors are quiet, simple, clean and compact. Novel shape, compact structure. Fully consider various use cases to achieve optimal operation, energy saving and saving money, clean air is guaranteed! Quiet: scroll's unique silent, micro-vibration provides a comfortable working space, even if it runs at night, there is no need to worry about affecting the environment. Energy saving: optimum operation and energy savings are achieved through multi-stage control. Multiple compressors are built into a single chassis. According to the amount of air used, the multi-stage control of free operation through the optimal number of units is adopted, which eliminates unnecessary operation and realizes energy saving; multi-stage control has energy savings beyond frequency conversion control.

Minimal energy-intensive on/off control. According to the amount of air used and the actual situation, the optimal operation is achieved, and the power consumption is greatly suppressed, and the energy saving effect is excellent. When the amount of air consumed changes, there will be a large error due to the different control methods of the compressor. The oil-free scroll compressor minimizes power consumption and thus enhances energy savings.

Quiet Operation
The oil-free scroll compressors are easy to operate and maintain. The scroll compressors are exceptionally quiet thanks to the slow speed of the scroll compression elements. The oil-free compressors are suitable for any working environment as they are WorkPlace Air System™ compressors.

High Quality Oil-Free Compressed Air
Enjoy peace of mind with Elang, thanks to the scroll technology along with pure oil-free air. The Elang oil-free air compressor will ensure your production is contaminant free to avoid any unnecessary downtime due to oil contamination in the future.

Oil- Free Water lubrication Compressor

Oil-free water lubrication screw air compressor is widely used in medical, food, electronics, chemical, packaging and other industries that require high-quality air sources, 100% pure compressed air division to ensure the process flow and product quality necessary measures, you can risk-free, safe to produce your high-end products. 1, the use of water as a compression seal, cooling medium, the use of low cost. 2. Through advanced sealing and isolation technology, the compressed air is cleaner and can be pure and oil-free. 3. The volumetric efficiency is higher and more energy-saving, which is more than 15% energy-saving than the second-level dry twin screw and more than 36% more energy-saving than the first-level dry twin screw. 4.

Avoid frequent dry screw and high host maintenance, and be more stable and reliable. 5, lower noise, single screw axial, radial are balanced by force, star wheel in the water film lubrication with the screw free rotation, so the host components in low load smooth operation, to ensure low noise and durability. 6. Compared with the traditional air compressor, it saves lubricants and consumables such as oil filters and oil and gas separation cores, thereby reducing maintenance costs. (One year is 1/5 of the maintenance cost of the traditional micro-oil air compressor) 7, there is no oil cost, so that the use is more environmentally friendly.
