Super-Efficient LGR Technology

LGR stands for low-grain-refrigerant. LGR dehumidifiers use low-grain refrigeration to efficiently remove moisture from the air in a given space. 

The WEL70-LGR uses a heat pipe precooling system collecting the warm air, cooling it, then heating and evaporating it once more. This process is repeated over and over with the aim of removing moisture from the air. This process makes the LGR dehumidifiers much more efficient than conventional compressor dehumidifiers.
