Air Compressor Health Tips

Get the most out of your compressor with these helpful air compressor health tips

With these air compressor health tips, the correct compressor system for your needs and a good maintenance program, you will be able to extend the life of your compressor, reduce running costs and increase efficiency.

Daily system checks

Is your compressor system part of your daily inspection checklist? We highly recommend that following daily checks are conducted and recorded every day:

  • Oil levels?
  • Any oil leaks?
  • Is there too much incoming voltage?
  • Does the control line filter need draining?
  • Are there any unusual noises or vibrations?
  • Are the gauges and indicators in normal operation?

Gauges and indicators can help you spot air leaks and monitor temperatures. The differentials across your compressor filter to check for air pressure (usually measured in PSI).

Overheating is a common problem with air compressors that have not been regularly checked and maintained. Ensure that your air compressor is kept in a well-ventilated area so that it can breathe and cool down, especially when the weather heats up in summer.

If the compressor system appears to be vibrating too much or making more noise than usual, ask us to take a proper reading.

Weekly system checks

  • Is the safety valve working?
  • Do the air receivers need draining?
  • Is the moisture separator draining?
  • Does water need to be drained out of the oil?

Monthly system checks

  • Clean the after-cooler and oil cooler
  • Wipe down the entire air compressor unit (dust increases chances of overheating)
  • Air filter service (sooner if the compressor is operating in extremely dusty or dirty conditions)

Quarterly system checks

  • Change the oil filter
  • Check the full load amps
  • Change the petroleum oil
  • Scan the compressor unit for loose bolts and re-tighten
  • Have an oil sample taken (we can test the sample to see if the oil needs to be changed)

Yearly system checks

  • Lubricate the motors
  • Check the safety shut-down system
  • Change the air filter every 2,000 hours
  • Change the oil separator every 4,000 – 8,000 hours

Your air compressor health in our safe hands

Our approach to compressed air maintenance will help to:

Winery Energy Saving Tips: Minimise Your Environmental Footprint

Winery energy saving. How much money will you save with a properly configured air compressor system?

Taylors case study

Taylors Wines in Clare Valley, North of Adelaide, has been producing a variety of red, white and sparkling wines since 1969. The site consumes just under 1,700,000kWh of energy per year, and Taylors wanted to know how they could create winery energy saving and reduce their environmental footprint.

Taylors were also motivated by the desire to be known as “Australia’s best wine company applying best practice principles in environmental management to enhance sustainable business activities and products“, and requested an audit of their air compressors.

While there wasn’t much room for improvement in the wine press, there was a significant improvement opportunity that presented itself in the bottling plant. In the bottling plant, two 15kW air compressors were running loaded for 57% of the time. By replacing these two units with a single 25kW air compressor with variable speed controls, Taylors were able to save an estimated 30% in energy use.

As compressed air experts, we understand how to assess your winery compressed air needs with your output and operational goals in mind. We frequently conduct energy audits to identify:

  • Incorrect compressor selection
  • Air leaks and pressure drops
  • Inappropriate usage
  • Poor reticulation design
  • Inadequate ventilation
  • System pressure settings

Poor maintenance also usually leads to loss in energy efficiency, increasing your energy bill and risk of break-down, business down-time and loss of product. Contact us today about an energy assessment and start saving money!

This study was reported by the Australian Government Department of Industry, Government of South Australia and South Australian Wine Industry Association Incorporated.

Some more energy-saving tips for wineries

Both operational and new winery businesses can reduce energy in their most common systems, which include:

  • Chilling and refrigeration
  • Lighting
  • Water heating
  • Plant and equipment
  • Air compressors

Ensure that your chillers are regularly maintained. Check for ice build-up and damage, ensuring that delivery lines and external coils are kept clean. A refrigeration engineer may help you achieve energy efficient systems. Insulate wine tanks and install variable speed controls. Efficient insulation will help prevent any condensation, ice build-up, minimising the overall cooling load.

Your staff may also be educated about energy efficiency and implementation of any strategic plansCellar fridges and any water fountains should also be turned off after hours.

Motion sensors will help reduce lighting energy use, and areas designed to allow for natural lighting will reduce the need for light installation. Check you light bulbs and ensure they are energy efficient.

Ensure that when not in use, equipment is switched off. Variable speed controls may be used to manage power output. Motors that are regularly serviced and put on energy saving modes will help reduce energy use and increase efficiency.

Consider solar heating for water heating devices where possible, and refrain from installing over-sized services or tanks with poor energy ratings. Insulate hot water lines to minimise heat loss, and use any waste heat from chiller or refrigeration systems to re-heat hot water. Timers will also help eliminate energy costs for after-hours.
