Whether you are designing a primary heating and cooling system or supplementing an existing one, the SEZ-KD12NA4R1.TH is an excellent addition.
Product Features
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 is run in dry mode, the coil's temperature stays just below the dew point of the return air, removing unwanted moisture. This improves your comfort and reduces the chance of mold growth and other property damage in the conditioned space.
Condensate Removal System
The SEZ-KD12NA4R1.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.
