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. The line has cooling-only models and models with heat (heat pump or electric heat) in a full range of capacities. And, Kuhl is available in ENERGY STAR ® -qualified models. Our Sizing Guide and Specifications by Model will help you select the appropriate cooling and/or heating capacity.

Call a distributor and put Kuhl to work in your commercial space. Our North American factory is only hours from our distribution center - not overseas - for fast delivery.

  • Kuhl Control.
    Intuitive controls allow one touch operation or programmable 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.

    Custom 7-day programs can be created to maximize comfort and/or energy savings around individual preferences. Create and save up to six custom schedules per unit. (requires optional Friedrichlink KWIFI accessory)

    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, Kuhl is the first room air conditioner that is Smart Grid capable.

  • Kuhl Efficiency

    From programmability to the refrigeration system, Kuhl is designed to reduce energy consumption.

  • Auto Fan mode saves money by conserving energy
  • ENERGY STAR®-qualified models, including all four heat pumps
  • Two built-in 7-day energy management programs. Optional custom programmability and BMS interface using KWIFI accessory package.
  • R-410A refrigerant used in all models
  • High-tech rifled copper tubing and slit fins have greater surface area for maximum heat-exchange efficiency.
  • Kuhl Quiet

    Gaps, insufficient insulation, and improperly mounted moving parts can contribute to operational noise. We designed Kuhl to minimize noise-causing vibration, outdoor noise intrusion and operating noise, while maintaining optimal air flow. Every unit has these important noise-reduction features:

  • Motor mount: The dual resilient rings prevent the metal-to-metal contact that causes noise and vibration
  • High-efficiency compressors: Mounted on extra-thick rubber grommets that absorb vibration
  • Solid-steel blower wheel housing: Provides maximum sound reduction
  • Steel inner wall, insulated plenum, heavy-duty hardboard side panels* and extra dense insulation: Blocks outdoor noise
  • Air discharge: Wider openings and better airflow design minimize airflow noise


  • Kuhl Purity.




    Kuhl's advanced dual-stage filtration system removes allergens, odors, ozone and other impurities from the air. By combining the optional carbon filter with the standard antimicrobial filter, Kuhl achieves lab-tested superior air filtration with ratings as high as MERV 6. Use the fresh-air vent and the exhaust vent for additional air-quality control.

    When both vents are closed, Kuhl cleans and conditions the air in your space. Open the fresh-air vent* and Kuhl purifies and conditions a moderate amount of outdoor air along with the air in your room. Use the exhaust vent* to release stale air and odors outside.

    *Excludes SQ & EQ models

  • Kuhl Comfort.

    The most comfortable temperature is the one you never notice. 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.

    Kuhl+ models have the ability to cool or heat as needed so units can operate as year-round central systems. And, like the most advanced central systems, Kuhl+ has auto-changeover*, which allows the unit to automatically switch between air conditioning and heating functions to maintain the desired comfort level. You won't have to lift a finger.

    Plus, Kuhl's air flow systems are tested for powerful and precise air distribution which means faster cooling when you need it most.
