The system can then be upgraded rack by rack or row by row by simply fitting and plugging in additional RDHx’s to a common under-floor or over-head manifold. New RDHx’s can be fitted in as little as 15 minutes without down-time. There is no need to re-position racks or use valuable additional space.
Connection Options and Features
The CDU can be fitted with an internal manifold allowing connection up to 8 racks with heat loads of up to 30kW. Alternatively, Flextails can be fitted, allowing multiple connections via an over-head or under-floor external manifold. Other optional features include Primary/Secondary Filters, ATS, Primary Flow Meter and Voltage options.
ServerCool® will save you 40% plus compared with other systems but the energy savings do not stop there. Because ServerCool® cools at source you can allow the white space to operate at a higher temperature, up to 27ºC, which saves more energy, and if you use the Eaton-Williams Close Control Products with high efficiency fans and free cooling you save even more energy.
Optimum use of the White Space
The RDHx takes up minimal space and, if required, the CDU’s can be installed outside the white space. Because the heat is removed at source, computer racks can be positioned close together.
Installing our unique and highly resilient plug and play manifold system, either overhead or under-floor, enables an upgrade path with low initial Capex. CDU’s and RDHx’s can be added with minimal disruption as the IT load increases and additional cooling is required. The manifold is tested to 5 × its’ working pressure.
Minimising initial Capex whilst building in the most efficient cooling system with upgrade potential are challenges faced by many Data Centre and IT managers. The Eaton-Williams ServerCool® system provides the perfect answer, enabling the system resilience, scalability, efficiency of space and power to be built in day 1 with excellent upgrade potential.
Small Server Room Cooling
The Modular CDU combined with the
RDHx is the perfect solution for the small
IT installation. The CDU is installed within a standard rack; taking up just 6U of space so leaving room for the servers above. The CDU Module provides up to 20kW of cooling and can be connected to a maximum of three RDHx’s. As room temperature is not critical to cooling the servers, the rack can stand in the corner of a room or even in a cupboard.
CDU Module Features
● Cooling capacity up to 20kW.
● Full run/standby capability.
● Leak-free quick-release couplings.
● Easy to install and retrofit.
● Dew point temperature control of cooling water.
● Auto-fill and bleed of coolant.
● Full alarm monitoring and connectivity.
Our fan assisted floor grille has been designed to boost airflow and cooling in areas with low or even negative floor pressure.
The Model TJH — Heavy / Extra Heavy duty floor grille complies with the requirements of the relevant sections of PSA MOB PF2 PS/SPU specification for Raised Access Floors March 1992 and IBM Management Design Guide for Raised Access Floors.
Our heavy duty floor grilles have been specifically designed to suit current industry requirements employing raised access floors in Data Centres. They are designed to replace a 600mm square tile and are aesthetically pleasing air distribution devices providing cool air exactly where required, eliminating high temperatures and reducing the risk of equipment failure.
The grille can direct airflow towards the rack inlet at up to 15 deg from vertical, this and speed control of the fans ensures that cooling is maximised efficiently. With up to 5 times the cooling airflow delivery of a standard grille in a low floor pressure area, this makes it an ideal solution for hotspots and problem areas that lack effective cooling.
Heavy Duty Floor Grilles and Fan Assisted Floor Grilles
The CDU Module is designed to provide close controlled cooling water for up to 3 RDHx’s with a total maximum cooling capacity of 20kW. It is the ideal system to start a planned upgrade path and is particularly suitable where space is restricted.
CDU Features
● Cooling capacities ranging from 20kW to t 260kw
● Full run/standby capability with redundant pumps.
● Optional internal manifold with leak-free quick-release couplings.
● Easy to install and retrofit.
● Dew point temperature control of cooling water.

The CDU provides essential separation of primary chilled water from cooling water to the racks / RDHx’s, meaning:
● Low pressure, clean water in rack environment.
● Low volume of water in secondary loop, reducing risk.
● Water flow controlled to maintain optimum operation and minimise energy use.
● Water temperature controlled at above dew point to maximise cooling and ensure condensate-free operation.
● Ensures 100% sensible cooling reducing the need for humidification and saving energy.
● Provides upgrade path and flexibility without major M&E upgrade work – plug and play.
● Provides essential monitoring of the racks being cooled and system health.
● Enables system redundancy through secondary manifold design.
● No potentially unreliable condensate pumps required anywhere in the system
The Cooling Distribution Unit (CDU) is designed to provide cooling water, close controlled and above dew point for up to 20 rear door heat exchangers. It is capable of 260kW cooling capacity. Designed and approved to work with IBM’s ‘Cool Blue®’ and ‘iDataplex®’ RDHx (Rear Door Heat Exchangers) and ‘Blue Gene®’ racks.
Water Cooled System Comparisons
The RDHx and CDU were independently tested against the five leading Data Centre cooling solutions by the Silicon Valley Leadership Group at Lawrence Berkley National Labs in California to establish an efficiency rating over a range of heat densities up to 12kW rack load. The graphic below represents the results; illustrating that the ServerCool® system is rated by far the most efficient cooling system at all heat densities.
Cooling Server Racks at Source with ServerCool® is the most energy and space-efficient solution for reducing Data Centre Costs.

Removing Heat at source with ServerCool
The complete solution for all your data centre cooling requirements:
● Rear Door Heat Exchangers (RDHx) ● Close Control Air Conditioning Units
● Cooling Distribution Units (CDU) ● Data Room Floor Grilles
● Cooling Distribution Unit Modules ● Surveys, Design, Install, Commissioning & Service
The CDU is an all important part of the system as:
● It controls the flow of clean, treated water to one or more RDHx’s at above dew point to ensure condensation free operation.
● Water volume is limited to a few litres at controlled low pressure.
● Individual racks can be isolated without impacting on others.
● It has N+1 reliability built in and if two CDUs are used in tandem can provide tier 4 resilience.
● Plug and play manifold provides scalability and white space flexibility upgrade path
● Only 5kW of power provides 260kW of cooling.
ServerCool® removes heat from the server rack at source by means of a rear door heat exchanger (RDHx). The RDHx then discharges the heat to the building chilled watersystem via a Cooling Distribution Unit (CDU). ServerCool® has no thermal impact upon the white space and minimal footprint. It was evaluated along with competing systems by the Silicon Valley leadership group and judged to be the most energy efficient for medium to high heat density server racks and has been shown to use just 20% of the energy used by conventional close control air conditioning unit based systems.
Cooling mission-critical data centres presents a number of challenges. With the power and heat densities of Blade Servers continuing to rise, managing the heat density and minimising the energy used for cooling are the highest priorities. After that, being future-proof and able to scale-up as the data centre evolves, are the next requirements. ServerCool® delivers all these benefits and more.
