FMCG producer saves 21 000 euros per year by installing Optimizer 4.0
A manufacturer of fast-moving consumer goods was looking for ways to save energy and reduce their carbon footprint. They reached out to Atlas Copco for support.
The Challenge
The customer has a compressor room with three oil-injected screw compressors – one of which is equipped with Variable Speed Drive (VSD). They were looking for solutions to reduce their carbon footprint and save energy.
The Solution
A Sales Engineer conducted an on-site study to analyze the compressors' operating patterns and recommended installing an Optimizer 4.0 Central Controller to optimize the energy consumption.
To showcase the potential benefits without any upfront costs for the customer, the Optimizer 4.0 was installed via a Try & Buy program.
The energy consumption was measured over a 3–4-week period in three different modes to ensure an accurate comparison.
No Control Mode – Compressors operate under normal pressure.
VSD Priority Mode – Compressors operate under normal pressure, but the main machine is the VSD compressor. This VSD compressor adjusts its speed based on demand, improving efficiency and reducing energy consumption.
Optimizer 4.0 Control Mode – Compressors are monitored and managed by an Optimizer 4.0.
The Outcome
Thanks to the new Optimizer 4.0, the customer achieved 12.1% savings – 8.6% energy savings and 3.5% additional savings by reducing the pressure.
This is equal to annual energy savings of 210 300 kWh and EUR 21 000. In addition, the customer realized a CO₂ reduction of 105 tons per year.
Eventually, the customer was convinced of the solution and purchased six additional Optimizer 4.0 Central Controllers for other sites. The six Central Controllers provide additional savings of 1.4 MWh (1 403 000 kWh) per year, equal to annual cost savings of EUR 105 000(*).
The Savings
(*)The savings were recorded via SMARTVIEW during a trial period with the Optimizer 4.0 installations. Annual savings were calculated based on the results.
