How to Clean Air-Cooled Equipment and Filters.
Reduce service calls and increase the efficiency of air-cooled condensers,
permanent air filters, evaporator coils, window units and other finned
cooling/heating coils or equipment by selecting one of Nu-Calgons
quality coil cleaners. They are based on nearly 60 years of experience
and technical background in coil cleaning.
Greasy dirt and dust in the air can collect on air conditioning and
refrigeration coils. If these finned heating or cooling coils are left
uncleaned, heat transfer will be reduced. In turn, compressors will have
to work much harder, operating costs go up and valuable equipment
could break down when it is needed most. For example, for every 2°F
rise in condensing temperature that is caused by dirty coils, efficiency
is reduced by 1% while power consumption is increased by 1%… a
staggering price to pay for dirty coils.
In addition, clogged and dirty permanent filters restrict air flow and do
not filter air, allowing dirt to contaminate rooms and stain walls around air
ducts. And dirty electronic air cleaners, fouled with pollen, nicotine and
other pollutants prevent them from adequately cleaning the air.
Regular cleaning with Nu-Calgon products protects equipment and helps
maintain peak operating efficiency.
