Kühl

Wireless Control, Astounding results.

Introducing Kühl

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, Kühl'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, Kühl is available in ENERGY STAR®-qualified models.

Contact your local Friedrich distributor and put Kühl to work in your space. Our North American factory is only hours from our distribution center — not overseas — for fast delivery.

Kühl is durable

Kühl's quiet technologies

Health & safety

Kühl 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 Kühl 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.

Kühl Components.

Superior components and construction. Attention to every detail.

Every aspect of Kühl is ultra-premium, outside and in, down to the tiniest component. Constructed with only the finest-quality materials, Kühl is extremely durable and designed to withstand tough use in virtually any commercial setting.

Outside: Kühl’s exterior is designed to prolong unit life.

Heavy 20-gauge steel cabinet
Distinctive rear aluminum grille protects the unit from damage and vandalism.
Aluminum endplates prevent rusted condensate from pooling in the drain pan, and eliminate rust stains on buildings.

Inside: You’ll find some of the most sophisticated, wear-resistant components inside every Kühl.

Robust, totally enclosed fan motors run at lower temperatures to prevent overheating.
Sealed controls enhance durability.

Plus, Kühl’s firm-grip interior handles make it easy to grasp the chassis during installation and removal.

Kühl Durability.

Outside Kühl's exterior is designed to prolong unit life.

Robust 20 gauge steel cabinet
Solid-steel blower housing offers enhanced protection
Totally enclosed commercial grade fan motor runs at a lower temperature to prevent overheating and is double-mounted for added stability and reduced wear (INSIDE FEATURE)
Solid steel base pans* and inner walls are durable
Unit's structural integrity allows it to be removed, cleaned and maintained outside of its sleeve
Distinctive aluminum rear grille protects the outdoor coil from damaging debris and vandalism.
Aluminum endplates prevent rusted condensate from pooling in the drain pan, and eliminate rust stains on buildings.
Scratch-resistant cabinet
High-tech aluminum fins with rifled copper tubing are more efficient and less prone to corrosion
Heavy-duty installation hardware lasts longer and provides a superior barrier from outside elements

Kühl Efficiency.

From programmability to the refrigeration system, Kühl 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.

Kühl Quiet.

Gaps, insufficient insulation, and improperly mounted moving parts can contribute to operational noise. We designed Kühl 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

*Excludes SQ & EQ models

Kühl Purity.

Kühl’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, Kühl 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, Kühl cleans and conditions the air in your space. Open the fresh-air vent* and Kühl 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

Kühl Comfort.

The most comfortable temperature is the one you never notice. Kühl uses five built-in environmental sensors to more accurately monitor indoor and outdoor temperatures so that it can maintain your ideal settings.

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

Kühl Testing.

Rigorous testing, ongoing quality control

Before Kühl hit the market, we carried out a punishing battery of tests in a UL-certified lab. We continue to test, refine and improve because our commitment to quality – and to our customers — demands it.

Airflow: Computational Fluid Dynamics (CFD) and validated empirical testing, including infrared thermography and smoke-trace analysis, to ensure maximum, uniform, directionally correct airflow
Capacity and Energy Efficiency: Confirmed in accordance with AHAM RAC-1 and DOE test requirements
Carbon filter: Gas Phase Capacity Test, VOC removal per IBR TM P300
Compressor: Stress tests for reliability
Electronic control hardware and software: Hardware systems endured extreme short-circuit, over-and-under voltage, high temperature, radiated emissions and electromagnetic pulse-spike susceptibility. Software tested using regression methodology to ensure logic and control states are achieved as designed.
