At the heart of each Kühl
unit, you’ll find the durable
components and heavy duty
construction that define the
Friedrich brand:
Heavy gauge
steel, rifled copper tubing, high
tech aluminum fins with sine
wave technology, aluminum end
plates that reduce corrosion,
totally-enclosed commercial
grade motors, high efficiency
compressors, vibration absorbing
technology and insulated air
plenums.
Friedrich conducts rigorous
performance tests to ensure
customer satisfaction and safety.
Run tests are performed- for
up to 120 continuous days-
under typical, and extreme,
temperature and humidity
conditions. Air flow systems
are tested for powerful and
precise air distribution, while
sound levels are measured to
ensure ultraquiet performance.
Premium air filters are tested
for adsorption capacities
and efficiencies. The unit’s
control software is tested
for constant and reliable
operation. Packaging exceeds
ISTA (International Safe Transit
Association) standards in order
to withstand transportation
hazards.
Quality components. Advanced
design technology. Extensive
product testing. It’s what you can
expect from Friedrich.
Our continuous testing ensures your Friedrich air conditioner
will perform up to our expectations— and beyond yours.
PERFORMANCE TESTING
Unit Performance
