For over 50 years, Mitsubishi has remained at the forefront of the mini split industry thanks to their dedication to providing efficient, user-friendly comfort solutions. The SEZ-KD18NA4R1.TH is a concealed duct heat pump mini split indoor unit for use in single zone and multi-zone systems. This unit is easily hidden in short-run ducting and operates quietly, making it the perfect choice for unobtrusive zoned comfort. With the SEZ-KD18NA4R1.TH, a small air register is the only evidence of that a powerful and efficient mini split is servicing your room. With multiple operating modes and multiple fan speeds, this unit fits the needs of nearly any room. Whether you are designing a primary heating and cooling system or supplementing an existing one, the SEZ-KD18NA4R1.TH is an excellent addition.
  • Hot-Start
  • Mitsubishi's hot start technology prevents cold drafts by delaying fan operation until the heat exchanger has warmed up.
  • Dehumidification
  • When the indoor unit runs in dry mode, the coil's temperature stays just below the dew point of the return air, removing unwanted moisture. This improves comfort and reduces the chance of mold growth and other property damage in the conditioned space.
  • Condensate Removal System
  • The SEZ-KD18NA4R1.TH contains an internal drain mechanism capable of lifting condensate 21-11/16". This simplifies installation and prevents condensate overflow, which can damage or destroy your property.
