Local cement factory can save 35 000 EUR/year with energy recovery
A leading manufacturer of eco-friendly cellulose fiber cement boards, wanted to improve the utility room while reducing boiler fuel and energy consumption.
The Challenge
The utility room consists of four oil-injected compressors. Three Atlas Copco units and 1 competitor unit. Two of them have 7 400 running hours per year each, which has a significant impact on the customer’s carbon footprint.
To explore the possibility of reducing boiler fuel consumption through energy recovery, the customer contacted Atlas Copco.
The Solution
Atlas Copco proposed a turnkey solution for the two compressors with high running hours. The proposal consists of two energy recovery units (one for each compressor) / two flow meters / two energy counters and two SMARTLINK Licenses.
- The Energy Recovery Units produce 58m³ hot water daily, heating it from 25°C (city water) to 85°C.
The flow meters, energy counters and SMARTLINK Licenses are used to measure, calculate and track the actual savings.
Based on the SMARTLINK data of the first three days, we are able to estimate the annual savings.
The Outcome
The data indicates a reduction in energy consumption of 1 238 000 kWh/year, equal to EUR 35 000 (MYR 163 000)/year. In addition, we are able to achieve a reduction of 767 tons/year of CO2 emissions.
This means that the payback period for the two Energy Recovery Units is less than 1 year.
