Energy savings in cold storage and logistics
In a cold store, compressors run around the clock and the temperature cannot drift. We cut energy use without touching the cooling process: we optimise voltage, compensate reactive power and write the saving into the contract.
Energy challenges in the sector
Compressors running 24/7
Refrigeration compressors are the largest load in a cold store and never stop, so even a few percent saved adds up to large sums over a year.
Poor power factor
Compressor and fan motors draw a lot of reactive power, which loads the transformer and can mean reactive energy charges.
Stable temperatures, no compromise
Any change to the power supply has to preserve storage conditions. That is why we measure the effect continuously and monitor the installation.
Measured results
Measured result at a cold storage centre running the technology we offer:
Artic Freezing Docks · cold storage and logistics
8.0% energy saving
Artic Freezing Docks: 8.0% saving, 2.5-year payback, 680 t less CO₂ a year. Refrigeration running 24/7, a stable −25 °C, better compressor efficiency and central monitoring in Schneider Electric PME.
Bofrost and Lineage Logistics also use the technology.
Frequently asked questions
Does voltage optimisation affect the temperature in a cold store?
No. The unit stabilises the supply voltage, while compressors and controllers keep working to their set points. At Artic Freezing Docks the −25 °C stayed stable with an 8% energy saving.
Will a cold store pay less for reactive power?
Yes, if it pays for excess reactive energy today. ICO-R compensates reactive power automatically, following the actual load.
Does battery storage make sense in a cold store?
It can, when demand peaks drive up the bill or backup power is needed. The meter data decides: when the peak occurs and how long it lasts.
