Modular Data Center Cooling


Compact, Economic, Greener, Ultra High Efficiency

Munters Oasis™ Optimum DCIE data center cooling solution focuses on energy efficiency. The modular design allows owners and operators clear budget optimization at the outset of a new data center build and follows LEED design concepts.

High energy efficiency and sustainability mean lower capital expenditure in addition to significantly lower annual operating cost.

Backed by our experienced in-house data center teams, Munters has designed and built hundreds of cooling systems for collocation, government, education and commercial clientelle.

Oasis ™ Optimum Modular Cooling

Flexible Data Center Cooling Solutions - the right choice

The heart of the Oasis™ Optimum DCIE cooling system is the Munters patented Evaporative Polymer Exchanger (EPX), which provides ultra-high efficiency cooling while using up to 75% less energy than traditional high efficiency systems.

In many cases the Oasis™ Optimum DCIE can meet all the cooling needs of a data center.

The Oasis™ Optimum DCIE can help data centers reach pPUE values below 1.1. The system is scalable in increments of 200kW* and the modules can simply be added on as your data center grows. This flexible aspect makes for the best choice in providing supplemental cooling or replacement of less efficient

equipment on existing data centers.

The Oasis™ Optimum DCIE is future-proof, and can easily accommodate advances in server technology and operating conditions.

*IT heat rejection capacity depends on the operating temperatures of the data center.


Proven technology - outstanding quality

Hot Aisle Return Air

The Oasis™ Optimum DCIE cooling system incorporates Munters innovative UL listed Oasis™ Indirect Evaporative Cooling technology for energy efficient cooling.

This patented system uses an air-to-air heat exchanger to transfer data center heat to a separate outdoor airstream. Fresh outdoor air is drawn across polymer heat exchanger tubes which are wetted with a water spray.

While filtered ambient air - scavenger air - flows over the saturated exterior tube surface, the evaporative heat transfer process efficiently cools hot aisle air flowing through the inside of the tubes.

The award-winning design of the Oasis™ Indirect Evaporative Cooler ensures 100% of the data center air is recirculated and uncontaminated in order to provide a clean, stable IT environment.

The systems have three modes of operation A: Sensible/Dry Mode

B: Evaporating/Wet Mode

C: Evaporating and supplementary Mechanical Cooling.

Principle of Operation

Exhaust / Scavenger Air Optional Condenser

Coil Optional Compressor Vestibule

Scavenger Outside Air

Hot Aisle Return Air Optional Cooling Coil (DX or CHW) Cold Aisle Supply Air

Hot data center air enters EPX Polymer tube for sensible dry cooling by the evaporating water film on tube exterior

Scavenger air flows up and around outside of tubes having extracted heat from air flowing inside tubes

Cooled air is ducted back to data center for heat extraction

Oasis™ Innovative Evaporative Cooling Systems

These highly energy efficient and scalable units are factory-built incorporating “plug & play” technology, and requiring minimal work on site

Consistently low pPUE’s accross variable loads

Matches airflow to actual IT demand. pPUE’s remain consistently low whether the data center is partially or fully operating at 100% capacity.


Built to meet zone A1 and A2 ASHRAE standard through to Tier 4 levels of resilience with N+1 components if required.


Significantly lower operational expenditure compared to traditional data center cooling solutions


Unit designed to be leaded easily using ISO 40ft containers, the truly flexible design will be fully configured and scaleable to suit your installation and capacity requirements .

New Innovative Approach that delivers added capacity

Munters Oasis™ Indirect Evaporative Cooling systems enable the IT equipment to be cooled to air temperatures of below 27°C/80.6°F (ASHRAE thermal guidelines for data processing environments 2009a) for more than 99% of the time without the need for mechnical cooling across a range of IT loads depending on the location.

The supplementary mechnical cooling system is only used for additional cooling during extreme weather conditions. The Oasis™ Optimum DCIE has three modes of operation for low energy data

center cooling which primarily utilizes free cooling. In the optimized mode natural forces are harnessed by adding water for indirect evaporative cooling to boost cooling. The filtered, ambient air is principaly cooled with indirect evaporative cooling. This saves siginificant amounts of money and carbon emissions. The third mode deploys mechanical cooling. The system is designed to achieve maximum efficiency.

“Enables up to 75%

reduction in energy

consumption vs. traditional data

cooling pPUE.”

National, European and International patents cover this innovative technology.
