Approximately 10% of all electricity used in industry is accounted for by compressed air systems.
It is a thermodynamic fact that around 95% of this energy is converted to heat and is wasted to the atmosphere through heat dissipated by the motor and cooling system, with the majority lost via the oil cooler.
Approximately 10% of all electricity used in industry is accounted for by compressed air systems. It is a thermodynamic fact that around 95% of this energy is converted to heat and is wasted to the atmosphere through dissipation by the motor and cooling system, with the majority lost via the oil cooler. Our heat recovery systems for air compressors, allow you to recycle the excess heat to your advantage. By re-directing the hot 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.
We provide a factory fitted integrated system and have the ability to retrofit installed systems including all pipework and fittings. Either way, the low investment costs result in long-term cost benefits. The heat generated during compression is paid for as part of the process, then paid for again during removal by way of cooling fans. Instead of simply removing the heat, it can be used to generate hot water, heating systems and on application processes in other areas of the installation.
CompAir’s innovative system delivers the opportunity to save money, energy and help to protect the environment. This is how it works. The basic principle lies in the transferral of heat into a medium and then transporting it to where it can be utilised. In the case of a closed air-cooled compressor, the cooling air becomes quite hot. This can be diverted to an enclosed area via ducting for heating. If water was to be heated, the oil in the oil cooler is chosen as the transfer medium. This will provide approximately 72% of the overall power consumption for water heating.
Think of how condensation in a home results from heat cooling and turning from gas into water. In an energy efficient home, heat recovery ventilation prevents the condensation from forming moisture that can cause mould and mildew, which can destroy your property. Our system is an efficient industrial version that not only is designed to extract the heat before condensation in the atmosphere, which can do damage, but convert it for use in other applications.
We use extractor fans and mechanical ventilation to achieve the end goal of fresh air and functional heating that can further your cost savings because the otherwise wasted heat is put to good use. In addition, the recycling of heat as a by-product will reduce the levels of C02 emissions. Whether it is a new build or not, we can provide recovery units required.
We have different products available to meet your commercial needs. For more information on how we can save you money by using your existing technology or installing the most appropriate ventilation unit or recovery unit, please contact us
