Air Receiver
Abacus Engineering Company offer compressed Air Receiver & air compressor tanks having volumetric capacity range from 300 Ltrs to 20,000 Ltrs, Fabricated as per IS-2825 / ASME SEC-VIII, DIV-1 codes and SS-304 / IS-2062 / IS-2002 as material of construction. All Compressed air tanks are stage wise inspected as per relevant code requirement. Abacus offers compressed Air Receivers having volumetric capacity ranging from 0.25M3 to 100M3. The air receivers can be supplied upto a working pressures of 300 kg/Cm2 g and are provided with all necessary fittings and accessories like inlets per ANSI – B16.5, Pr. Gauges. Safety Valves and Auto / Manual Drain Cocks etc.
Air receivers are tanks used for compressed air storage and are recommended to be in all compressed air systems. Using air receivers of unsound or questionable construction can be very dangerous. Therefore, the American Society of Mechanical Engineers (ASME) has developed a code regarding the construction of unfired pressure vessels, which has been incorporated into many federal, state, and local laws. This particular code is ASME Code Section VIII Division 1. Air receivers should always meet or exceed this code in addition to any other state, municipal, or insurance codes that may apply.
The ASME also approves the receiver accessories. They are equipped with a safety valve, which is set at a pressure lower than the working pressure for which the air receiver was stamped and at a higher pressure than the operating pressure, to safeguard against excessive pressure. In addition, receivers have a drain valve to eliminate accumulated moisture. They also have pressure gauges, handholes or manholes, and a base for vertical air receivers. Standard receivers are designed for horizontal or vertical mounting.
Air receivers serve several important purposes:
- Decrease wear and tear on the compression module, capacity control system and motor by reducing excessive compressor cycling.
- Eliminate pulsations from the discharge line.
- Separate some of the moisture, oil and solid particles that might be present from the air as it comes from
the compressor or that may be carried over from the aftercooler. - Help reduce dew point and temperature spikes that follow regeneration.
- Offer additional storage capacity made to compensate for surges in compressed air usage.
- Contribute to reduced energy costs by minimizing electric demand charges associated with excessive
starting of the compressor motor.
There are wet air receivers (supply) and dry air receivers (demand).
Wet Receivers: Wet receivers provide additional storage capacity and reduce moisture. The large surface area of the air receiver acts as a free cooler, which is what removes the moisture. Because the moisture is being reduced at this point in the system, the load on filters and dryers will be reduced. The term “wet receiver” refers to the storage vessel or tank placed immediately after the
compressor. This device helps with contaminant removal, pressure stabilization and
pulsation reduction.
Dry Receivers: When sudden large air demands occur, dry air receivers should have adequate capacity to minimize a drop in system air pressure. If these pressure drops were not minimized here, the performance of air dryers and filters would be reduced because they would no longer be operating within their original design parameters.The term “dry receiver” refers to the receiver placed after the air dryer and other air
preparation equipment.
