Gardner Denver is expanding its Ultima oil-free compressor line with a new air-cooled model that provides Ultima U75 -160 process heat recovery.
Gardner Denver has released a new version of its innovative air-cooled Ultima U75 - 160 technology, which continues to set the benchmark on the market, being the world's first oil-free air-cooled compressor to provide heat recovery for process water.
Ultima’s innovative and patented closed package cooling
system allows for the collection and recovery of up to 98% of the heat that is
generated during the compression process. This energy can be harnessed to
provide process water heating,
reaching usable water temperatures of up to 85°C. In
fact, Ultima is the first and only air-cooled, oilfree air compressor on the
market, capable of тutilising
heat recovery for process water heating.
Ultima has the added benefit of “hybrid cooling mode”
operation. Depending upon the most economic cooling method at the time (eg in
the case of seasonally changing availability of cooling water) Ultima can
operate in either air-cooled or watercooled mode or a combination of both
concurrently.
By utilising the superior design of the closed loop
water system, Ultima requires no air for internal cooling. Ultima processes cooling
air within the compressor and utilising a heat exchanger, cools the internal air,
then recirculates it via the base frame around the compressor. This also
ensures that no dust or particulate can enter the inside of the compressor. As
a result, installation is made easy with no requirement for ducting, compressor
rooms can be kept to the minimum size, noise levels are greatly reduced and
machines can be easily installed at point of use.
With best-in-class features, the Ultima air-cooled
compressor delivers cost savings of up to 13% compared to industry standards,
even without the need for additional heat recovery. Thanks to variable speed
fans, energy consumption under standard environmental conditions or at partial
load is further reduced.
