The STULZ WPAmini Keeps It Cool In Mission Critical Applications
STULZ has announced the launch of the WPAmini chiller with integrated free cooling. It has been designed specifically for data
centres with low cooling requirements and industrial chilling.
The compact chiller will deliver a cooling capacity up to 160kW in a very small space. The chillers are operated with two
redundant refrigerant circuits to increase operational reliability. Both circuits are controlled on the basis of the required cooling
capacity, so that the respective circuit is activated with maximum efficiency when minimal cooling is needed.
The WPAmini is equipped with maximum size aluminium
microchannel condensers and four scroll compressors. The
compressor operating time can be reduced to a minimum
using the optional free cooling facility, which will
considerably reduce power consumption, and
operating costs.
Three operating modes are available in total:
DX mode, free cooling mode and mixed mode.
In mixed mode, cooling capacity is generated
by means of simultaneous free cooling and
compressor cooling. This means that significant
energy savings can be achieved even at
moderate outdoor temperatures. Thanks to the
technology, this latest innovation from STULZ
can also run in extreme local climates.

Fluke Establishes Microsite Resource To Support Data Centre Personnel
To support the smooth running of data
centres, Fluke has developed a web
microsite specifically targeting those
running and maintaining the infrastructure.
The site provides a range of downloadable
information for data centre personnel.
Easy contact is made possible with an
expert from Fluke who will be able to advise
on the best Fluke tool to solve a problem.
The microsite offers downloadable
content, including:
‘Data Center Solutions’ – showing a plan
of a data centre and suggesting checks that
should be made and suitable Fluke tools for
carrying out those tasks.
‘Six essential tests to keep your UPS
system running’ – describing the regular
testing of individual battery cells as well as the UPS system as a whole.
‘Monitoring temperature, humidity and airflow in data centres’ – a US-based application article describing the use of a
thermal imager and an airflow meter to monitor the true ambient conditions.
‘Detecting electrical unbalance and overloads’ – describing the use of a thermal imager, power quality and other electrical
test tools to monitor and resolve issues.
