Executive SummaryWorldwide PUEs Comparison Operational Expenditure & ROI Selection Guide & Features Real Projects
To help reduce energy consumption in datacenters AST Modular has developed 4 ultra energy efficient and modular cooling solutions that can be implemented in both traditional and containerized datacenters. AST Modular Data Center Cooling Modules have been engineered with the aim of drastically reducing OPEX whilst allowing for future growth and density increase thanks to a scalable approach. Energy Efficiency and Modularity are indeed the cornerstone concepts of our newest addition.
In the attempt to meet the different scenarios that data center operators face, we have designed both air based and water based cooling modules. The four available models represent the fruit of our R&D work over the last 3 years and provide great levels of energy efficiency and security whilst still showcasing specific features. A selection guide at the end of this catalogue highlights common features and peculiari-ties attached to each of them to help you select the right technology.
EXECUTIVE SUMARY
Natural Free Cooling ModulesNFC
NFC Modules, a worldwide patented AST Modular’s technology, are an indirect air to air and evaporative cooling solution that leverage temperature differences between outside cold air and hot IT exhaust air to cool the data center. NFC Modules provide multiple types of econo-mization and are capable to select between air-to-air, adiabatic and mechanical cooling to run your mission critical applications in the most efficient way.
Chilled Water Block ModulesCWB
CWB Modules are a water based datacenter cooling technology composed of a chiller, variable-speed fans and a water coil whose surface is bigger than the one of a traditional Computer Room Air Conditioning (CRAC). The extended cooling surface of the coil allows the chiller to supply water to the coil at higher tempera-tures, thus resulting in improved energy efficiency.
Direct Free Cooling ModulesDFC
DFC Modules use external air to cool the datacenter by driving the air from the outside to the inside of the datacenter. The mechanical cooling support system is activated only when the external dry bulb tempera-ture exceeds 27° C and therefore does not meet ASHRAE requirements
Hot Corridor Exchanger ModulesHCX
HCX Modules are a water based overhead cooling technology composed of a chiller, variable-speed fans and a water coil, whose surface is bigger than the one of In Row Cooling Units. The extended cooling surface of the coil allows the chiller to supply water at higher tempe-ratures, thus resulting in improved energy efficiency.

Data Center Cooling Modules

Energy consumption is a critical issue for IT organizations today, whether the goal is to reduce cost, protect the environment or to keep the datacenter up and running. According to Gartner, energy-related costs account for approximately 12% of overall data center expenditure and are the fastest-rising cost in the data center. Power cost problems are likely to worsen during the next few years as organizations grow their technology infrastructure , emerging from a recessionary period. Data Center inefficiencies threaten the profitability of business.
SCALABILITY ENABLING FUTURE GROWTH AND DENSITY INCREASENFC and DFC Modules feature 50 KW cooling capacity for each module whereas CWB are available in 100KW and 150KW models. Finally HCX can be purchased in the 7,5KW and 20KW version. Regardless of the different cooling capacity, all the cooling modules have been designed to easily scale along with your business needs, allowing for additional cooling capacity to be deployed quickly in a live environment and without disruption to the service. This results in minimizing capital expenditure and maximizing efficiency.
RIGHT SIZINGWhen the IT load is uncertain data center cooling systems are often oversized and operate inefficiently. Therefore, it makes sense to plan for modular growth of the cooling systems. AST Modular Cooling Modules allow you to avoid overbuilding in advance of actual needs and give your cooling infrastructure the flexibility needed in today’s economic climate.
SERVICEABILITY & LOW LEVEL OF MAINTENANCE NEEDED The specific design of AST Modular Cooling Modules makes them easy to maintain. Most of the modules feature an independent maintenance area, separeted from the IT space and maintainable without load interruption.
ADAPTABLE TO IT LOAD VARIATIONAST Modular’s Cooling Modules feature an accurate air management system that allows variable speed fans to match different server flow requirements. By constantly monitoring pressure and temperature the system ensures consistent and efficient cooling across various IT loads.

REAL PROJECTS
AST Modular promised our Tier 3 Data Center would run under an average yearly PUE of 1,09. We have been able to lower it down to 1,07. The energy efficiency, reliability and robustness of NFC is just amazing".

TECHNOLOGYNatural Free Cooling Modules, a worldwide patented AST Modular’s technology are an indirect air to air and evaporative cooling solution that leverage temperature differences between outside cold air and hot air coming out of the servers. Thanks to its heat pipe exchanger technology and the intelligent control system NFC Modules provide multiple types of economiza-tion. They are capable to select between air-to-air, adiabatic and mechanical cooling to run your mission critical applications in the most efficient way.
MULTI ECONOMIZATION EXPLAINEDNFC Modules capitalize free cooling at 100% with dry bulb temperatures below 20° C/68 F. They operate with adiabatic cooling with average wet bulb temperatures below 20 ° C/68 F and are supported by a chiller when ASHRAE’s temperature and humidity ranges cannot be met, specifically with wet bulb temperatures above 20° C/68 F. Unlike direct free cooling systems, NFC Modules are the first solution in the market able to prevent cross contamination and humidity within the datacenter. The exhaust air coming from the servers is cooled inside segregated chambers and no outdoor air is introduced into the IT space. As a result the datacenter remains as a sealed enclosure, unaffected by external conditions such as humidi-ty, pollution, corrosive gases, and particles. This approach drastically reduces filter, maintenance, and fan power costs, thus resulting in added security, resiliency and much better energy efficiency than direct free cooling technologies.
MODULESNFC Modules have been designed and are available in 50kw individual modules. This scalable approach enables the custo-mer to purchase only the cooling capacity needed to meet current requirements. Additional NFC units can be added as the data center load grows.

The external temperature limit to which NFC Modules can work is related to the cold corridor desired temperature which each data center operator may choose. The following graph illustrates the temperature limit up to which NFC modules are able to work without any cooling support at different server loads (40%, 70% or 100% IT Load). As an example, if we have a data center load of around 70% overall and would like to keep the cold corridor temperature at 25ºC, as per ASHRAE recommended levels, NFC modules will operate without the need of any chiller below 20ºC/71.6F external temperature.

Data per Module
It is recommended to use a water treatment system such as a reverse osmosis unit with demineralizer (not included in AST Modular’s offer).Alternative Adiabatic system can be supplied without previous notice.
ADIABATICCOOLING
Evaporative cooling comes built into each module in order to leverage wet bulb temperatures. At certain locations where humidity levels are high, the adiabatic cooling systems can be optionally not included.
The system is composed of the following parts:
Rack with water atomization nozzles and electronic valves
High pressure connection pipes
Pump assembly with continuous modulation (inverter)

AST Modular NFC Modules present the following operational ranges:
Feeding conditions towards Cold Corridor: Between 21°C/69.8F 27°C/80.6F, 35-55% R.H. according to ASHRAE recom-mended values. Higher limits can be applied upon request.

TECHNOLOGYDirect Free Cooling Modules are a cooling solutions able to leverage outdoor fresh air by driving it from the outside to the inside of the data center. Direct Free Cooling generates significant savings since in certain locations data centers operators can take full advantage of free cooling for several hours of the day without the need of expensive mechanical cooling. Indeed the back-up cooling support embedded into DFC Modules is activated only when ASHRAE recommended temperature levels cannot be met and specifically beyond 27°C/80.6F external dry bulb temperature.
MAIN COMPONENTSFilters: to protect the equipment from dust and air pollution.Motorized Dampers: Each module is composed by 3 sets of dampers. Supply air dampers, Exhaust air dampers, By-pass dampers.Fans: variable speed fans guarantee accurate air flow management and adaptability to variable loads.Mechanical Cooling Support System: available both as Chilled water (CW) or as Direct expansion (DX).
MODULES & MODULARITYDFC Modules are available in 50kw individual modules. This scalable approach enables the customer to purchase only the cooling capacity needed to meet current requirements. Additional DFC units can be added as the data center load grows and installed in a “live environment” without disruption to the service.
21
DFC
DIRECT FREE COOLING
WHY WOULD YOU USE DFC MODULES?
• Lower capital investment than with Indirect Natural Free Cooling Modules.
• Ideal where cross contamination and external contaminants (pollution, corrosive gases, humidity) are not a matter of concern.
• Scalability. Add modular cooling capacity “as needed”.
• Suitable to both traditional and modular datacenters.
• Reduce up to 70% energy consumption over other cooling designs.
Phase 1 External Temperature < 18ºC/64.4F (Limits upon customer’s preferences)
The dampers of DFC Modules mix the outside fresh air with the hot air coming from the datacenter to achieve the correct supply conditions. The outside air is filtered before entering the IT area. Filtering is performed according to site conditions and the level of security required and part of the air coming from the datacenter is exhausted towards the outside with intake air pressure given by the fan. Variable speed fans together with dampers match the airflow needed to cool the datacenter to the temperature required.The Mechanical Cooling Support System is not in use.
Phase 2 18ºC/64.4F < External Temperature < 27ºC/80.6F (Limits upon customer’s preferences)
22
OPERATION
The outdoor air is blown into the cold corridor and no outside air is mixed with the hot air coming from the datacenter. The whole of the hot air coming from the servers is exhausted towards the outside with intake air pressure given by the fan. Variable speed fans match the airflow needed to cool the datacenter to the temperatu-re required. The maximum external temperature allowed inside the cold corridor varies upon design conditions and compliance with ASHRAE limits.The Mechanical Cooling Support System is not in use.
23
Phase 3 External Temperature > 27ºC/80.6F (Limits upon customer’s preferences)
No free cooling is available, hence the mechanical support cooling system is in use. The system recirculates the air from the hot to the cold corridor and cools down the servers to the desired temperature and upon design conditions.Two cooling systems are available: Chilled water (CW) or Direct expansion (DX). Variable speed fans match the airflow needed to cool the datacenter to the temperature required.The Mechanical Cooling Support System is in use.
