Crenlo’s Emcor Enclosures and R4 Ventures Enter Partnership — Data Centers Can Reduce Energy Costs up to 85% with New Cooling Technologies

Rochester, MN – July 23, 2015. Crenlo, an international leader in the manufacturing of cab
and equipment enclosures, announced today that its Emcor Enclosures business unit and R4
Ventures LLC (R4V) have entered into a joint marketing venture where the two companies
will partner to offer new cooling technologies for data centers.
Data center energy usage has risen dramatically the past 10 years and will continue to grow
in-step with the processor-intensive, high-density applications used in high performance
computing. Cooling is not only a logistical challenge that can cause significant downtime and
lost capacity, but it is also costly for data centers, representing up to 40% percent of a data
center’s energy usage. R4V’s patented Real Time Data Center Cooling System technology
paired with Emcor’s high quality server enclosure cabinets can save the average data center
50% to 85% on cooling energy usage and costs.

“R4V offers a critical energy efficient cooling option for the data center market,” said Kevin
Jackson, business development manager for Emcor Enclosures. “The sheer size and cooling
needs of data centers today have surpassed many of the cooling applications currently
available. R4V and Emcor Enclosures are now positioned to provide significant energy and
cost savings that will drive the market for years to come,” added Jackson.
“R4V applies semiconductor clean room process cooling methods (versus traditional
comfort cooling) to data center server enclosure heat loads. This patented method cools heat
loads before hot air enters data center space. Our technologies eliminate hot and cold aisles
and expensive containment. We cool and control fluctuating enclosure heat loads in real
time and maintain a ± 2 °F data center space set point temperature,” said Dr. Darrell
Richardon, chief executive officer for R4V.
