50% Less Heat. No Increase in Energy Use. Power Density Potential More than Twice the Industry Standard.

Silver Linings Systems Data Center Modules have superior heat removal capabilities primarily because of who designed them.

Many of the products using IEA radiators consist of megawatt engines housed in ISO-style containers.   While the degree of heat dissipation presented by these products dwarfs that posed by stacks of IT equipment in a containerized data center, it does create the need for a specialized form of heat control…one that focuses on energy minimization, uninterruptability and automation.

To the knowledge and experience gained from developing products respected by the world’s major engine manufactures, the IEA engineers who developed the Silver Linings Systems products added confidence and innovation to create unique, in some cases patentable, ways of removing concerns over the impact of heat from data center operations….and in so doing developed an entirely distinctive concept for the data center

Heat-Scrubbing Air Flow

The Main Challenge: A column of hot air moving across the fins of a heat exchanger core will have only a portion of its retained heat removed if only a portion of the air actually comes in contact with the fins. (Think of how much of the water in a flowing river ever touches either bank or the river’s bottom.)

However, if the column of hot air can be made to move in irregular patterns (i.e. tumble), the amount of air-to-fin surface contact will increase. That will significantly improve the cooling capacity of the core without a corresponding increase in energy consumption; i.e., the increase is basically free. The key is to get the air to “tumble”.

The patented surface design of the fins in Silver Linings Systems’ tube/fin cores creates enough turbulence in the hot air stream to increase heat removal up to 50% over the same amount that would be possible with “smooth” air. Yet it costs no more to move that air through the “scrubbing” core.

But improving airflow through the radiator’s core does not, by itself, generate PUEs as close to perfect as physics will allow.

Effectively Cooling Modular/Enclosed Data Centers

The Economic Challenge: The key to cost effectively cooling IT equipment housed in any form of enclosed structure is assuring that the cooling is applied proportionately to the heat being produced; in terms of both the level and location of the heat source.

Since many of the traditional cooling methods introduce air at the bottom of a rack and exhaust it at the top, equipment in the upper layers is forced to operate in considerably hotter conditions than that at the bottom. Some such systems even recommend periodically rotating equipment top to bottom to equalize the damaging effects.

In those systems that simply provide air to the middle of a rack, the problem is compounded, in that equipment located in both the lower and upper corners of a stack can experience performance-degrading and life-shortening higher temperatures.

Smart Air Flow

Silver Linings Systems Modules solve this problem through the design of their air-flow system. Rather than just a few large fans pushing the air, Silver Linings Systems uses a grid of smaller, high efficiency, variable speed, low energy-use units strategically placed to ensure complete coverage of all equipment in the rack and a more uniform heat dissipation.

In addition, each fan is electronically controlled to respond automatically to both temperature changes in and airflow resistance of specific pieces of equipment within the rack. Should areas of a rack be empty, the fans assigned to cool that area will never turn on. In other words, the fans operate only when and only to the degree needed, keeping energy use as low as possible, while maintaining the maximum desirable equipment environment.

Augmented Convective Cooling™

While traditional cooling systems rely primarily on natural convection to circulate hot air up and away from the racks, Silver Linings Systems utilizes fan-equipped return ducts.  The heat laden exhaust air is drawn away from the IT equipment, then up, over and back down through the heat exchanger core. This patented “push-pull” design, known as “augmented convective cooling” in Silver Linings Systems parlance, ensures more cooling air reaches more IT equipment in a more even, consistent and reliable way, ensuring the most complete, yet lowest cost, IT equipment cooling.

Patented, Industrial Caliber Cooling Technology Outperforms Any CRAC or CRAH System

Each Silver Linings System Module contains its own on-board cooling system, using the most cost favorable methodology based on prevalent local weather conditions. A variety of optional designs are possible. The exceptional energy efficiency is produced by a combination of:

  • Highly efficient cooling air flows, created by our patented heat exchanger components, which can dissipate up to 50% more heat than conventional “air conditioning” systems but with the same energy consumption.
  • Close proximity of the cool air sources to the IT equipment
  • Tightly confined air flow in and out of the hot and cold aisles within the modules’ structures
  • Definitive electronic monitoring and control of cool air dispersion against the housed IT equipment, avoiding energy waste due to “overcooling” and equipment damage due to hot spots. A Silver Linings System Module is able to adjust its cooling responses to immediate variations in the IT equipment heat loads, eliminating the peaks-and-valley syndrome common with less precise methods and reducing the excess energy costs those methods generate.

The combination of these factors makes Silver Linings Systems Modules the least expensive, and greenest, to operate data center structures you can buy

Consistent low temperature within the entire equipment rack ensures proper cooling of servers


Thermal dispersion testing of Silver Linings Systems Modules (conducted at sister-company IEA’s state-of-the-art calorimeter laboratory) indicated only a very slight difference in interior temperatures across the entire face of the equipment rack. In no case did temperatures in any area rise above maximum allowable levels. Variances in IT equipment cooling were attributed to the individual response characteristics of the different types of equipment housed in the rack.

150% Upside Potential

Silver Linings Systems Modules can continue to effectively cool even when kW density expands over time. On average, a Silver Linings Systems Data Center Module can properly cool up to 150% more wattage/square foot than it was originallydesigned to handle. Such unique expandability greatly extends the life of the owner’s investment, and provides the flexibility needed to accommodate inevitable equipment upgrades. It also eliminates the need to replace data center structures obsoleted by density growth, significantly reducing total investment and increasing the overall ROI.

Many Other Benefits

But even the most effective and dependable cooling solution is just one of many reasons Silver Linings Systems Modules are the best choice for building a new or expanding an existing data center. Among the many others benefits gained are:

  • Lowest initial investment in a modular data center
  • Lowest energy consumption when compared to alternative solutions
  • No restrictions on brands or type of equipment housed in the data center
  • No need to build-out or renovate buildings to accommodate a new or expanded data center
    or server room
  • Fastest available design and delivery of Module Data Centers
  • Increased service efficiency and resulting lower maintenance costs
  • No loss of business efficiency or competitive edge due to inability to fund expansion
    of computing capacity.
