Ever since the introduction of ADAP-KOOL® refrigeration controls systems a number of tests have been carried out world-wide to verify that performance corresponds to our customers’ expectations. In a comparison test in Edeka Germany two identical supermarkets were equipped with different Danfoss controllers:
- The first was equipped with basic Danfoss electronic refrigeration controls and thermostatic expansion valves (red columns)
- The second was equipped with Danfoss adaptive controls and electronic expansion valves type AKV (green columns)

The Blue line illustrates savings in percent which were 24% or 79.929 kWh/year in 2006. With an additional cost of EUR 14.000 for the ADAP-KOOL® solution (second supermarket) the pay back time will only be 1.9 years by an energy price of EUR 0.10 per kWh!
