The Ultimate 340 is one of the most effective and versatile drying devices available. The Ultimate 340
removes more water and has more grain depression than other refrigerant dehumidiers, even though it
only requires 10 amps of electricity.
The term LGR (Low Grain Refrigerant) was created to describe the unique drying capabilities of this
dehumidier. These units were known for delivering substantially drier air, as well as for drying areas to
much lower humidity levels than conventional dehumidiers.
