BANKING: SA Bank Invests R19m for 9 YMC2 Chillers


Recent Gauteng Business News

First National Bank (FNB) has been following a strategy to lower its energy
consumption and costs, and improve its eco footprint for a number of years.
However, with its existing chillers reaching end of life, maintenance was
becoming expensive (over R1m on the last year) and part replacement was
becoming increasingly difficult and time consuming. In simple terms, current
efficiencies were being overshadowed by what could be achieved with newer
technology. Their top three requirements for the replacement solution were:
that the chillers provide proven energy efficiencies, meet the Montreal
Protocol requirements with regards to use of ozone friendly gas (i.e., 134A
rather than R22 gases), and that there be reputable and reliable local
support capabilities. Johnson Controls and its YMC2 chillers met all these
requirements and replaced the bank's existing chillers at its headquarters
with nine new York Magnetic Centrifugal Chillers (YMC2), with a projected
time to ROI in just under three and a half years.

Johnson Controls Systems and Service have a long standing trusted relationship
with FNB who have made use of York solutions in the past and as such, are
confident that the YMC2 chillers will meet all their requirements. Johnson
Controls have the feet and expertise on the ground to support and service
the equipment. In fact, Johnson Controls York technicians have been sent on
advanced training courses on these new chillers to ensure they will meet
service level agreements that Johnson Controls have in place with the

Johnson Controls' YMC2 chillers are 10% more efficient than conventional,
variable-speed chillers and include an optimised centrifugal compressor that
utilizes low temperature, cooling-tower water to save energy. Along with
optimal energy efficiency, the YMC2 is also quieter than any comparable
chiller in the market place as magnetic-bearing technology eliminates
driveline vibration and reduces noise at off-design conditions, allowing the
YMC2 to be perceived at about 50% of the volume as other magnetic-bearing
chillers. This chiller furthermore features a sustainable design using
refrigerant HFC-134a.

The chillers will be installed in phases between May and September with
expected energy usage savings of up to 25%. "With power costs leaping up by
another 25% in the near future, it's going to be crucial to manage
consumption. At Bank City, the chillers account for half of all the power
consumption, so this is an important investment in long term cost
efficiencies - which contributes to the organisation's overall
competitiveness and makes for an even brighter green eco footprint for our
