Kühl is a deep line with cooling capacities from 5400 Btu/h to 3 tons. Its unique features take comfort and energy efficiency to a new level. Easy to handle and install, Kühl can cut maintenance time and costs.

Our team of engineers worked closely with our commercial division to design a unique package of features for commercial applications. It’s that attention to detail that makes Kühl the choice for commercial-grade cooling. Kühl offers:

  • Better energy management: Utilize one of the built-in energy management schedules or program your own using FridrichLink™. Program up to four distinct temperature settings per day for seven days to keep energy consumption and costs under control, particularly when spaces are unoccupied. Kühl can be operated using the unit’s LCD control panel or remote control, as well as with a smart phone, computer or tablet (requires internet access). Plus the LCD settings lockout feature prohibits occupants from changing the temperature.
  • Auto-changeover feature for convenient comfort in all seasons: Kühl+ heat (electric heat or heat pump) units switch automatically between cooling and heating to maintain a comfortable temperature during shoulder seasons and in spaces with wide temperature swings. (Excludes EQ08 model)
  • Cooling for any space: Unlike many manufacturers, we give you a full range of capacities in one line. Kühl can cool a single room or large commercial space efficiently and cost-effectively, so there’s no need to install an expensive central system.
  • Improved air quality: Kühl’s larger vent openings provide superior fresh-air intake and stale-air exhaust*. The optional premium carbon filter used with the standard antimicrobial filter has filtration ratings as high as MERV 6 while absorbing odors and reducing ozone and VOCs.
  • Easier installation and maintenance: Kühl’s firm-grip handles and slide-out chassis make installation and removal much quicker. And remote access to operational logs and codes make maintenance easier as more efficient.

Explanation of Slide-Out Chassis vs. Fixed

There are two types of chassis: fixed and slide-out. A fixed chassis should be installed only in a window so that it is accessible for service and maintenance. A slide-out chassis can be installed in a window or thru-the-wall since the inner workings of the air conditioner can be accessed easily. In general a slide-out chassis is easier to install and remove.

Heat Pumps

A heat pump is an air conditioner that also can run in reverse to provide heat. In air conditioning mode it removes heat from the indoor air and expels it outside. In heating mode it extracts heat from the outdoor air and uses it to heat your indoor space. At peak efficiency heat pumps use 1/3 of the electricity used by an electric heat unit. However, heat pumps heat most comfortably and efficiently when the average winter temperature stays above 45ºF. They are not well suited to, or as energy-efficient in, colder climates.


Air Filter MERV, or Minimum Efficiency Reporting Value, expresses in a number from 1 to 16 an air filter's efficiency in capturing airborne particles from 0.3 to 10 microns in size. Using the ASHRAE Standard 52.2 Test Procedure, an aerosol containing particles is injected into an air stream that passes through the filter. Airborne particle counts are recorded for each particle size, both upstream and downstream.

Ozone and VOCs

Ozone forms when sunlight interacts with nitrogen oxides from automobiles, manufacturing plants and other emissions. VOCs, or volatile organic compounds, come from a variety of sources, including chemical compounds like solvents, inks and coatings. In combination, ground-level ozone and VOCs have been shown to harm health, so reducing them is desirable.
