Albini Energia has installed an oil/water heat exchanger on the air compressors in the customer’s spinning department.
After performing a detailed energy audit, the company identified the area requiring improvement. The aim was to recover heat from the compressors and use it to heat the plant’s sanitary water without the need to use a methane gas powered boiler.
Thanks to the heat exchanger, 6,000 L/h of water can be heated to a temperature of between 25 °C (when heating requirements are at a maximum) and 5 °C (in the summer).
The cost benefit obtained as a result of the energy efficiency measure amounts to €12,000/year 144 white certificates are issued each year; the installation was paid back in 3 years.
