Installation of air compressors and accessories, air piping, vacuum, blowers and pneumatics

Compressed Air Controls service all brands of air compressors

Compressed Air Controls can install:

Our experienced, qualified Service Technicians can organize all or part of an install, any time of the day. We can conduct installations outside of your production hours.

Our installations include us ensuring there is:

  • Adequate ventilation
  • Correct piping design
  • Condensation waste is draining efficiently
  • Pressure vessels/receivers are correctly installed and meet safety requirements

Our Service Technicians make sure that compressors, air piping, vacuum, blowers, and pneumatics are installed as per the manufacturer's guidelines and industry best practice.

This will make sure that the compressor has a long life and will provide optimum performance, and reduces energy costs. 

Compressed Air Controls follows best practice when installing aluminum piping systems which is not to bend it to go around corners but not use elbow couplings instead.

Bending aluminium air piping would compromise the air piping’s coating and integrity and may cause it to fail.

It is also best practice to ensure that air compressors are not exposed to the elements and are either housed in a shed or some sore of covering is built over it.

These are the five aspects they take into account when deciding where to install the compressor:

1. Location; this is the most important aspect when installing an air compressor

 During installation, we need to ensure there is sufficient area available for the:

  • Unloading
  • Installation
  • Operation
  • Maintenance of the air compressor.

The designated area must be equipped with enough clearance around it.

For rotary screw compressors, however, no special foundation or anchoring is required. The compressor must be placed on a level surface that can withstand the load of the compressor and the equipment used to move it.

Furthermore, we make sure the compressor is protected from natural elements including

  • Rain and sunlight
  • Hot air
  • Toxic or flammable materials
  • Corrosive agents like ammonia, chlorine, salt spray, and other chemicals as they erode the internal components, contaminate the oil and damage the filters.

2. Ventilation; a lack of this, and cooling, is the leading cause of trouble in air compressors

The electricity delivered to your compressor is completely transformed into heat during compression and that heat is dissipated into the compressor room.

To make sure your compressor is sufficiently cooled, the following measures can be adopted:

Natural ventilation:

If the temperature inside the compressor room doesn’t exceed 5 ˚C when compared with the ambient temperature, the natural ventilation is sufficient.

Forced ventilation:

  1. This is done with an exhaust fan: we will install an exhaust fan if the temperature inside the compressor room exceeds 5 ˚C.
  2. Forced ventilation with ducts: We will ensure the hot air exhaust from the compressor is diverted through ducts when it is installed in an enclosed area.
  3. Install a cabinet heater if the air inlet temperature drops below ambient temperature. Use the cold start kit and heater in the compressor room to maintain the temperature at 0˚C - 50˚C.

3. Electrical

Compressed Air Controls will make sure that the electrical service voltage matches the voltage on the compressor nameplate (located inside the electrical cabinet) before installing the compressor

The compressor will be:

- Properly grounded

- Properly equipped: The appropriately sized fuse or circuit breaker should be installed between the compressor and the main electric service.

The actual operating voltage must be within +/- 10% of the compressor nameplate voltage. Insufficient or excessive voltage will directly affect the compressor's electrical system.

For variable speed drive units, the Service Technician will make sure that the power supply transformer has a symmetrical, three-phase supply. In a symmetrical three-phase supply, the phase angles and voltage are all the same.

4. Air storage: via an air receiver tank is an integral and important part of any compressed air system

The selection of an air receiver is crucial to meet the demand of the plant and the effective operation of the compressor (load/unload).

What are the benefits of an air receiver tank?

  • The receiver tank acts as a reservoir of compressed air for peak demand.
  • The receiver tank helps remove water from the system by allowing the air to cool.
  • The receiver tank minimizes pulsation in the system caused by a reciprocating compressor or a cyclic process downstream.

Receiver tanks are required to have a pressure relief valve and a pressure gauge. The relief valve should be set to 10% higher than the working pressure of the system.

It is also important to install a manual or automatic drain on the receiver tank to remove water from the system.

5. Pipework: The correct size of pipework is important to provide sufficient flow and steady pressure to all points of use

Pipe diameter directly impacts the pressure drop. Discharge piping must be at least the same diameter as the compressor discharge outlet.

Pipe selection directly affects three key elements of a compressed air system (flow, pressure, and air quality). Poor choice of pipe materials, diameter, and layout causes flow restrictions and frequently results in a significant pressure drop.

Pipe bends are an additional source of friction losses in compressed air piping, which is why Compressed Air Controls use couplings, instead of being pipe, to go around corners. The pressure drops due to an increase in friction with the flow. Friction loss is also affected by the pipe type and the length of the pipeline.

The compressor air outlet must be on top of the common/main header pipe to avoid condensed water entry when the compressor is idle. Make sure the air inlet to the receiver is at the bottom, and the outlet from the receiver is on the top to avoid moisture-free air to the dryer or customer equipment.

The pipelines must be flushed before downstream filters like the prefilter, fine filter, and carbon filters are assembled. We will make sure the water drain is in provision with the auto drain for the air receiver, downstream filters, and dryers. We will also provide a bypass for piping arrangements of the dryer and downstream filters in case of isolation.

A good installation of a compressor system makes all the difference in performance, efficiency, and the overall lifecycle of the system and prevents direct or indirect expenses in the future so contact Compressed Air Controls.
