Unique cooling
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, oil-
free air compressor on the market, capable of
utilising 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 water-
cooled 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.
Even greater efficiency
When any regulated speed compressor gets to the
minimum speed, it goes into idle run. For any compressor,
this is wasted energy. Ultima uses 45% less energy in
idle run than a conventional two-stage compressor and
a 160kW compressor uses less than 8kW in idle run.

Unlike the majority of oil-free airends that quickly succumb
to performance degradation, the German engineered and
manufactured airends featured in Ultima, use a special
coating to ensure maximum efficiency and protection
throughout the life of the compressor.
Lowest noise levels
Ultima is extremely quiet. Even the 160 kW
models, do not exceed a noise level of 69 dB(A)
(water-cooled) and 70 dB(A) (air-cooled). This is by
far quieter than any comparable oil-free compressor
on the market and a great benefit for customers who
would like to operate the compressor at point of use.
