Mitsubishi MLZ-KX-Series 2-Zone Ceiling Cassette Features and Benefits

  • 20 SEER2 Efficiency – Delivers strong energy savings and efficient performance.
  • Dual-Zone Comfort – Provides independent temperature control for two rooms.
  • Ceiling Cassette Design – Fits neatly into the ceiling for a clean look.
  • Quiet Operation – Helps maintain a comfortable environment in everyday spaces.
  • Mixed Space Coverage – Designed for a combined area of about 700 to 1,000 sq. ft. total, depending on conditions.

Discreet Comfort

The slim ceiling cassette indoor units install flush with the ceiling, helping keep walls and floors clear while maintaining a clean, built-in appearance.

Zone-Based Control

Each indoor unit can be controlled independently, allowing different temperature settings in separate rooms for better comfort and efficiency.

Right-Sized Performance

With one 9,000 BTU and one 12,000 BTU indoor unit, this system is a practical choice for mixed-size spaces that need efficient and reliable climate control.
