Management, a division of Eastman Companies, is a highly respected Class A
commercial real estate management firm in New Jersey.
They are constantly on the lookout for new ways to operate their
properties more efficiently, to give their tenants the best office
conditions possible, to provide optimized return on investment to the
property owners, and to offer exceptional service to both.
In June, 2001, Ron Thomson, Facilities Manager for Eastman, was
requested by The Prudential Insurance Company, one of Eastman’s tenants
in a Livingston, NJ office complex, to assist with the installation of
several TWT Deposit Control Systems in their Prudential Cafe.
The Deposit Control Systems were purchased to replace water
softeners and chemical treatment in the Prudential employee food service operation,
which suffers from scale buildup and operating inefficiencies when their
water supply is left untreated.
The existing water softeners were being removed or by-passed
because they were expensive to use, because they prevented the water from
receiving treatment on a continuous basis due to frequent downtime and
maintenance needs, and because the use of softened water sometimes led to
corrosion in pipes and equipment. In addition, from a health conscious viewpoint,
Prudential also wanted to avoid the increased probability of leaching in the plumbing
infrastructure that softened water is known to promote,
as well as to avoid
passing along increased sodium intake to café customers.
provided the requested assistance, and in the process was introduced to
TWT’s patented deposit control technology.
A skeptic at first, Mr. Thomson quickly came to recognize the value
of TWT Deposit Control Systems when the results achieved in the Prudential
cafeteria were demonstrated to provide superior treatment and lower costs,
with no maintenance requirements.
these results, Mr. Thomson and his associates at Eastman speedily decided
that a test of the TWT systems was in order.
Their first purchase was for treatment of one of their commercial
facility hot water heaters, followed by another system for one of their
cooling towers, the maintenance of which was the source of a great deal of
man/hour expenditures and of materials and chemicals expenditures.
As well, existing conditions presented the
need for constant monitoring of the cooling tower to prevent bacteria growth.
Eastman purchased a TWT system to treat the tower, installed it,
and waited to see what would happen.
Within one month, results were visible in terms of the lack of
scale buildup, the decreased chemical costs, and the decreased manual
maintenance and supervision man/hours that were needed.
next few months, Mr. Thomson and his associate, Robert Clark, Chief
Engineer, continued to see pre-existing scale disappear, to see decreased
chemical costs and handling safety issues, and experienced no downtime due
to the need to clean the tower, nor need to replace parts that might
previously have corroded due to either biofilm buildup or from chemical
treatment. Said Mr. Clark,
“the tower looked as clean as it did when it [the tower] was

decreased water and energy usage. Here’s
why: the TWT Deposit Control System allows a cooling tower to operate at
higher TDS ratios than are the norm with conventional chemical treatment,
easily reaching levels of 7 to 8, and even higher, if desired.
This means the blowdown for the tower is significantly reduced,
providing immediate water savings and sewer charge reductions.
The energy savings were also significant, because the equipment
could now operate as it was designed to, and did not have to “work as
hard” to meet the building’s needs.
According to information from the U.S. Department of Energy’s
Office of Building Technology, State and Community Programs, cooling tower
treatment and optimized operation can be expected to account for as much
as 50% of the energy savings obtained at a given facility in relation to
the Department’s standard set of identified energy wasting conditions;
in other words, when assessing targets for achieving energy savings,
cooling towers are a very high priority and almost always yield very
significant reductions in consumption.
So, this simple installation is estimated to pay for itself in less
than 20 months, and will continue to provide energy and other savings,
year after year.
savings, chemical savings, energy savings, water savings, sewer charge
savings, reduction in downtime, extended equipment lifecycle, and enhanced
equipment performance, have all added up to a most positive experience for
Eastman Management, which looks forward to rolling out the TWT systems to
many other of the properties they manage.
“We’re extremely pleased with the reduction in required
maintenance interventions, and with the fact that we no longer have to use
chemicals or have our personnel be exposed to them.
The cost reductions also allow us to deploy our resources in ways
that are more visible and which tenants and owners can better perceive and
appreciate. We have already
expanded the TWT treatment program to 11 more towers, and we have plans to
install them on many more over the coming months”, stated Mr. Thomson.
forward to completing the rollout of systems across Eastman-managed and
owned properties, and to helping provide continued significant results.
