About the KHTB series

The KHTB series is a ducted unit for high static pressure. The indoor and outdoor units are compact and lightweight thanks to a smaller base chassis and less material overall, which makes installation easier. Slanted corners at the top reduce air turbulence, and the plastic casing and fan lower the noise level. Cooling and heating both keep working at low outdoor temperatures.

The rating tests the unit on an imaginary reference house. The design load is what that house needs at the design temperature (−10 °C in the average European climate), not the unit’s capacity; where the unit falls short of it, the rating assumes an electric backup heater covers the difference. The “at least” figures show what the unit delivered to that house at the stated temperature, not the most it can give.

According to the manufacturer, the unit heats down to an outdoor temperature of -15 °C.
