The Free Joint Multi Inverter cooling machine has a weatherproof sheet steel housing with a torsion-free base frame for outdoor installation. Equipped with a TWIN BLDC inverter rotary piston compressor, vibration-damped, extremely quiet and energy-saving. Newly developed sickle-shaped fan, directly driven and electronically balanced ensures whisper-quiet operation. The refrigeration system is prefilled with R32 safety refrigerant at the factory. The ideal solution for air-conditioning various rooms with different indoor units from the Free Joint Multi series with a super-quiet, compact cooling machine.

R32 Refrigerant

The air conditioner system uses the next-generation R32 refrigerant, has an Ozone Depletion Potential (ODP) of zero and a lower Global Warming Potential (GWP) than conventional refrigerants, so it’s more environmentally friendly and has a lower impact on global warming.

Twin BLDC Compressor

A key contributor to Samsung Free Joint Multi(FJM)†s efficiency is its advanced compressor technology. Adopting Twin Brushless Direct Current(BLDC) rotary compressor with premium moving parts, Samsung FJM delivers efficient and reliable performance.

Smart Inverter System

Samsung FJM cools in outdoor temperature in 46°C and warms in -15℃*, eliminating need for additional units to cope with adverse weather. Its smart inverter system delivers your set temperature quickly, and keeps performing fine-tune adjustments to ensure a constant, comfortable environment.
