Energy Efficiency Audit Services

Air Power South West has the expertise and technology to perform on site energy efficiency audits and air compressor plant surveys free of charge with no obligation. By utilising our planning and optimisation services it is possible to identify specific areas where improvements and cost savings can be made by upgrading and improving compressor plant and ancillary compressed air pipework systems. Outdated and inefficient compressed air generating systems result in increased running hours,a spiralling increase in energy costs and higher maintenance bills. With rising energy costs it is now more important than ever to operate all components of your compressed air system to the maximum efficiency.

Air Power South West employs state of the art, bespoke Intelligent Controllers, designed to manage and optimise efficient compressor operation for individual or multi machine systems. Optimal compressed air regulation provides maximum operating efficiency throughout the plant.

Retrofitting an inverter to an existing compressor can also help to reduce unnecessary unloading, resulting in reduced machine running time and energy savings.

Decreasing operating air pressure by 1 bar will result in a 7.5% reduction in electrical energy consumption and air pipeline and system leakage will be reduced by approximately 10% which will collectively be translated into huge energy savings.Industrial surveys carried out by Carbon Trust have reported that compressor system leakages can very often be in excess of 20% of compressor plant capacity.

Compressed Air System Demand 250 CFM @ 7.5 Bar

System Power Demand 45Kw

Annual Production Hours 4,000

Average Kw/Hr Energy Cost 10p

RUNNING COST= 4,000 x 45 x 10 = £18,000

PRESSURE REDUCTION BY 1 BAR

7.5% x (4,000 x 45 x 10) = £1,350

Leakage Reduction 10% of 50 CFM = 0.9Kw x 4,000 X 10 = £360

TOTAL SAVING = £1,710

Compressed Air System Demand 1,000 CFM @ 7.5 Bar

System Power Demand 160Kw

Annual Production Hours 8,760

Average Kw/Hr Energy Cost 10p

RUNNING COST= 8,7600 x 160 x 10 = £140,160

PRESSURE REDUCTION BY 1 BAR

7.5% x (8.760 x 160 x 10) = £10,512

Leakage Reduction 10% of 200 CFM = 32Kw x 8,760 X 10 = £2,803

TOTAL SAVING = £13,315

Leak Detection South Wales

Compressed air is energy. Leaking air lines, couplings and hoses are simply put, sources of energy waste. The majority of companies have a leakage rate of more than 20%. Apart from being completely unnecessary, it is expensive and contributes to your CO2 emissions. In an Industrial Air Power leakage management program your leakage level will be reduced to less than 5%. What does leakages presently cost your company?

Industrial Air Power will be pleased to discuss with you a 'Leak Management Program' where we will identify and tag leaks and present you with an in depth written report. This will highlight:

  • Leakage Rate
  • Leakage Waste Costs
  • CO2 Emissions
  • Percentage of repaired leaks

If you would like to discuss a Leak Survey of your current system, savings of 20% or more of your current electrical running costs are possible. For more information contact us today.

Case History

We recently carried out a Leak Survey at a production plant with an average compressed air usage of 1200cfm. Following the survey we identified leaks of more than 400cfm (30%) equating to savings of £56,000 per annum. Within weeks savings of almost £10,000 were achieved with a structured IAP Preventative Maintenance Plan.

Inefficient compressed air generation can cost your company unnecessary expense. Spiralling energy costs now dictate the need to run you compressed air system to its maximum efficiency. Optimising compressed air generation to suit individual requirements is absolutely essential in today’s competitive market.

Reducing system pressure by 1 bar is the equivalent of a 7.5% reduction in consumed electrical power. In addition system leakage will be reduced by approximately 10% reflecting the reduction in pressure.

Your company may be eligible for interest free funding for energy modifications.

Energy Recovery South Wales

Benefiting the environment and reducing energy costs

Production requires power, and power costs money. Consider that the average price for oil, natural gas and coal have all increased significantly in recent times and will likely continue to do so. These increases — as well as the global focus on preserving the environment — have driven many businesses to look into new ways to conserve energy.

The overwhelming majority of the energy used to run a compressor is converted into heat through the compression process and this heat is normally left to absorb into the cooling cycle. With up to 85% of recoverable energy potential from the heat of compression, an energy recovery system can significantly reduce total energy consumption.

The Atlas Copco Energy Recovery System (ERS) provides a cost-effective way to reduce your energy bills and benefit the environment by capturing this heat and putting it to work. The Atlas Copco coolant-to-water heat exchanger utilises the thermal energy captured in the compressor coolant to heat water up to 70°C (160°F).

This hot water can be used in a variety of applications, including:

  • Pre-heated boiler feed water
  • Process water
  • Wash-downs
  • Showers
  • Tap water
  • Space heating with hot water heaters
  • Many other applications that call for warm or hot water

By supplementing your current water heating system with recovered heat, the Atlas Copco ERS allows you to significantly reduce your total energy consumption without the addition of any further losses and without compromising compressor reliability in any way.

Energy Recovery South Wales

Is old equipment making your business uncompetitive or simply costing a fortune in energy bills?

An interest free loan will give you the opportunity to both modernise your business and simultaenously reduce overheads with your loan repayments covered by the estimated energy savings. The loans are unsecured and interest free with no arrangement fees and a straight forward application process with loans repaid over a period of up to four years. The scheme is designed for energy savings to cover repayments - the loan will effectively pay for itself.

Who is eligible?

Your organisation must fulfil the following criteria:

  • Private Sector
  • Trading for at least 12 months
  • Acceptable Credit Rating
  • Based in the UK (England, Scotland and Wales)
  • All small or medium enterprises (SME) or any business that do not qualify for participation in the Carbon Reduction Commitment (CRC).

Loan Criteria

The size of loan available and the repayment periods will be based on your projected CO2 savings, which will be assessed by the Carbon Trust. For full details of how a loan could work for you IAP can arrange a meeting with a local Carbon Trust Loans advisor.
