Rittal produces precision climate control units called CRACs for data centers. The CRAC units ensure optimal temperature and humidity conditions for IT equipment in data centers handling high thermal loads. There are two types: CRAC DX units which use direct evaporation and have an external air-cooled condenser, and CRAC CW units which use cold water for cooling and have an external recooling system. The document provides specifications for several models of each unit type, including their cooling output capacities, dimensions, fan and filter configurations, and optional features.
The units of the P series are highly configurable for complete control of the temperature, humidity and quality of the air by means of accessories such as the humidifier, the electric post-heating unit and high efficiency filters. The direct expansion PX versions are available, with air condensing and matching remote condenser, or with water condensing and incorporated plate heat exchanger, as well as the PW version with the cooled water circuit. The PX versions present the optional DC brushless inverter compressor for efficient modulation of delivered power. The Twin Sources solution is also available, with a second alternative cooling source. The Free Cooling maximises energy savings thanks to the external air that cools the water with an external dry cooler. Advanced microprocessor electronic regulation for integrated control of the unit with a standard RS485 card.

The units of the G series are designed with construction characteristics that optimise the space and layout of technical floors. The fan section is composed of a separately provided sub-base, providing remarkable advantages: a coil with ample heat exchange surface area, an extended filtering surface that limits maintenance operations thanks to less soiling, and horizontal air delivery for operation with less pressure drops. The G series is available in the GX versions, with air condensing and matching remote condenser, or with water condensing and incorporated plate heat exchanger, as well as the GW version with the cooled water circuit. The PX versions have the optional DC brushless inverter compressor for efficient modulation of delivered power. Advanced microprocessor electronic regulation for integrated control of the unit with a standard RS485 card.
NRP is a multifunction unit charged with R410a gas for the simultaneous but independent production of hot and cold water. The 2-pipe units are designed for applications where cold/hot water and domestic hot water is required throughout the year. The 4-pipe units are designed for systems where hot and cold water may be requested simultaneously. The machine is fitted with axial fans with reduced sound emissions, and scroll compressors with a high yield and low electricity absorption. The NRP has 3 heat exchangers: one on the environment side (finned pack copper/aluminium) and 2 indoor (shell and tube).

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

Description of accessory components
Inverter-regulated scroll compressor
The inverter-regulated compressor permits modulating adjustment of
the cooling output to the current heat loss in the room.
This facilitates energy-efficient cooling, particularly in the part-load
range, and avoids major temperature fluctuations in the server inlet air.
Electronic expansion valve
The electronic expansion valve combines superior energy efficiency with
increased functional reliability of the units.
Fan with EC motor
The fan is connected directly to a synchronous EC motor with integral
switch system for constant, demand-based adjustment of the rotation
speed.
Condensate pump
This accessory is comprised of a housing with vertical pump, tank with
float and microswitch to activate the pump, plus water and electrical
connections. 10 metres of crush-proof spiral drain pipe are supplied
together with the pump. The electrical connection comprises the
power supply and an alarm signal for heat and overcurrent protection
which is displayed on the microprocessor. The pump operates fully
automatically.
Depending on the size of the CRAC unit, the pump is either installed in
the factory or supplied loose.
Steam humidifier
The steam humidifier allows controlled humidification of the air in the
data centre.
Dehumidification system
The dehumidification system allows the air in the data centre to be
dehumidified at high levels of relative humidity.
Reheater
The reheater is used to raise the air outlet temperature after dehumidifi-
cation.
Fine filter F5
Reusable air filter with efficiency class F5.
Interface BACnet, Ethernet, SNMP, TCP/IP serial board
Base frame
Used to bridge the height of the raised floor; available in three different
heights.
Kit for noise reduction in external condenser units
Apart from the standard version, two kits are available for the external
condenser unit to reduce noise emissions.
