Why heat Recovery
It is a thermodynamic fact that around 94 % of the energy needed to run a compressor gets converted to heat. Without heat recovery, this heat is directly blown into the atmosphere.
The heat generated during compression is paid for as part of the process, then it creates additional costs as this heat needs to be removed by cooling fans. At the same time, most companies consume a lot of energy and money to generate hot process water, space heating or preheat water for steam generation.
Given that compressed air systems account for 10% of all electricity used in industry, and energy is the largest single lifecycle cost of a compressor, it makes sense to recover this heat, save energy and reduce costs.
"Recovering the excess heat from your compressor saves money and reduces your carbon footprint"
It's critically important that we focus on energy now and in the future:
Turn this waste heat to your advantage: recovering it will you to save huge amounts of energy, cut CO2 emissions and improve operating costs.
Give your compressed air system an efficiency upgrade
With heat recovery system from CompAir, the heat generated by the compressor can be re-used, providing the following BENEFITS:
- Significant savings in energy costs
- Short payback time - low investment costs payback time typically less than 1 year
- Lower CO2 emissions
- Turnkey solutions
- Easy installation and operation
- Small ecological footprint
- High reliability
- No impact on the compressed air supply
CompAir Heat Recovery Solutions
The basic principle lies in the transfer of the heat to a medium and then transporting it to where the heat can be utilised.
CompAir heat recovery options
Instead of simply removing the heat from the airend, it can be used to generate free hot process water or supplement hot water heating systems by utilising a high-efficiency oil-water heat exchanger – factory fitted, retro fitted or as a CompAir energy recovery box.
Oil to water heat exchanger
By re-directing the hot cooling oil to a high efficiency oil to water heat exchanger, the heat can be transferred to water, raising the temperature to a required level for a multitude of applications - heating, process, production or washing:
Heating
Heat recovery systems are perfect for augmenting your facility’s heating system. By utilising the heat energy from your compressor(s) that would otherwise go to waste, you can keep your premises warm, reduce your heating bill and cut back on your company’s carbon emissions.
Hot water
Heat recovery systems can provide up to 72% of the energy required to heat your hot water system. By utilising the heat energy that would otherwise go to waste, you can have running hot water and cut back on your company's carbon emissions.
Industrial process
Heat recovery systems can also be used to pre-heat the water supplying your process application requirements, for example, steam generation. Anywhere hot water is required, supplying pre-heated water makes the process more cost efficient.
Defined air outlet
An enclosed, air cooled compressor with defined air outlet can transfer the total amount of heat of the cooling air for ambient air heating:
Ambient air heating
The compressor’s heated cooling air can be utilised to increase the ambient temperature of rooms instead of being dissipated into the atmosphere. By ducting the air to somewhere where it would be more useful, you can increase the ambient temperatures of those rooms and save on their heating costs.
