Introducing Kuhl
The only commercial grade room air conditioner tough enough for the most demanding applications. Everything about these category-leading units is designed for maximum quality, ease and control. From the 20-gauge steel cabinet and fully enclosed fan motors to the 7-day programmability and LCD control lockout, Kuhl's advanced design was created with industrial applications in mind.

Kuhl Control
Simple unit controls or whole building control at your fingertips. Simplified intuitive unit controls easily switch between operating modes, fan speed and temperature with a push of a button. Built-in 7-day energy management programs are based on a typical 5-day work week and a typical 5-day business week. Wireless Unit operation makes controlling a Kuhl possible from a smartphone, computer or tablet. Friedrichlink, a proprietary web-based portal allows access to an unlimited number of Friedrich units. Make changes on the go, wherever you are. And, FriedrichLink allows users to create "Groups" of air conditioners, controlling them as one. Create your own zones or central systems using room air conditioners. And, Kühl is the first room air conditioner that is Smart Grid capable.

Kuhl uses five four five built-in environmental sensors to more accurately monitor indoor and outdoor temperatures so that it can maintain your ideal settings. Plus, Kuhl's air flow systems are tested for powerful and precise air distribution which means faster cooling when you need it most.
