The peculiarity of our product is to optimize the IPLV parameter (Integrated Partial Load Value) introduced by United States' norms ARI (Air - conditionings & Refrigeration Institute).To optimize this parameter means to reduce the refrigerator unit energy consumption during the entire running period, therefore to reduce running costs and energy impact, as current international energy situation require.Using 2 scroll twin compressors for each circuit, allow us to obtain a IPLV parameter of 195%
