Tampa, FL – With rising energy costs, lower
maintenance budgets and decreased indoor air quality are challenges facing
every facility manager across the country. But potential savings can be
right under an organizations nose. Case in point: dirty or clogged
commercial evaporator coils. Simply performing a deep
cleansing/sterilization with PURE-Steam coil Cleaning and Flushing can
dramatically reduce energy costs, while improving in indoor air quality and
with no chemicals.
Cooling coils use tubing
arranged in a series of loops and fins and their purpose is to transfer heat
from one fluid to another (e.g. water to air, refrigerants to air, air to air
etc.). Aluminum and copper fins are attached to the coils to increase the
exposure surface and the rate of heat transfer. In the 1970s and early 1980s
the cooling coils had typically 8 to 12 fins per inch, but due to increasing
energy costs and mandated energy efficiency ratings, it is not uncommon seeing
coils today manufactured with 16 and 18 fins per inch arranged in complex
zigzag patterns. Unfortunately, these high efficiency coils are extremely
susceptible to blockage from dust accumulation because once lodged deeply
within the fins bacteria and mold may initiate growth, which not only compounds
the blockage problems but also gives rise to excessive operating costs, comfort
control problems and unhealthy sanitary conditions that are not conducive to
good air quality.
A recent research paper
published in the Continental
Automated Buildings Association (CABA) magazine on Evaluation
of Steam Cleaning in AHU Coil Sanitization and Energy Conservation emphasizes both the energy
impact as well as environmental impact of PURE-Steam coil cleaning.
With energy costs rising,
Florida State University (FSU), a major Florida university, took a close look
at HVAC maintenance, including the total operating cost of its HVAC
system. They found that the conventional coil cleaning foam/rinse method
only superficially cleaned the surface of the coil and pushed small debris
further into the coil causing decreased air flow, a musty odor, decreased
temperature and humidity control and decreased the quality of the indoor air.
The forward thinking
Facilities Management Department at Florida
State University (FSU) felt
these dirty coils were nothing but a pot of gold buried in dust and debris in
these air handling systems. FSU discovered quickly that professionally steam
cleaning their evaporator coils has paid huge dividends for them. They
found a chemical free steam coil cleaning process so efficient and safe for the
environment that in the first year of its implementation alone saved the
university over $800,000 of their power bills and were able to provide the
students and teachers a healthier learning environment. The estimated payback
in less than eight (8) months was 157% return on investment (ROI).
Because dirty coils are
difficult to clean, expensive to operate, unhealthy and can lead to humidity
control deficiencies, it makes sense to minimize the amount of dust that can
enter the airflow and to clean them before dirt accumulation becomes visible.
Pure Air Control Services (PACS), an industry leader in environmental and
mechanical cleaning technologies recommends not to defer coil cleaning to the
point that dust accumulation is visible. Minimally, heat exchangers should be
cleaned once a year using the superheated steam process. For non specialized
environments (healthcare facilities, clean rooms, etc.), Pure Air Control
Services also recommends using air filters with an equivalent Minimum
Efficiency Rating Value (MERV) of 8 and to minimize the amount of air that could
infiltrate in the air handler by ensuring that the filters fit snuggly in the
holding racks and sealing all cabinet penetrations.
Charlotte County School
District has implemented the PURE-Steam "Green Cleaning" program to
not only save energy but also to improve indoor air quality and mitigate
long-term health risks and allergies associated with indoor air pollutants.
This program introduces a chemical free coil cleaning process called PURE-Steam
Coil Cleaning a safe
and effective cleaning process used to save energy and create a healthy
learning environment for students, school staff and visitors.
As a part of this initiative,
the Charlotte County
School District has
contracted with Pure Air Control Services a national leading indoor
environmental contractor with over 25 years of building IAQ experience.
Because the PURE-Steam Coil Cleaning program is totally GREEN (NO CHEMICALS)
students, school staff and visitors don’t have to worry about potential
dangerous chemicals or Volatile Organic Compounds (VOC) entering into the air
or water system.
Don Terry, Manager of HVAC
Maintenance noted that “not
only are we saving energy, but we are creating a healthy learning environment
for our students and faculty.”
The U.S. Environmental
Protection Agency (EPA) has long been a proponent of improving indoor air
quality in the nation’s schools stating on their web site that “Poor indoor air
quality (IAQ) can cause illness requiring absence from school, and can cause
acute health symptoms that decrease performance while at school. In addition,
recent data suggest that poor IAQ can reduce a person’s ability to perform
specific mental tasks requiring concentration, calculation, or memory.”
Indoor air quality (IAQ) is a critically important aspect of creating and
maintaining quality school facilities.
Additionally, Mr. Terry
stated that “your
staff, crew and support team are great to work with. I would highly
recommend your PURE-Steam Coil Cleaning process to any facility/HVAC manager
interested in saving energy, improving indoor air quality and creating a
