The demand for data centers is growing at a rapid pace and keeping these facilities constantly operational is essential. With an absolute focus on reliability, the industry is now also seeking to reduce energy consumption and carbon emissions associated with data center operations.

Munters OASIS IEC Series 600 Cooling Unit for Data CenterWith a wide range of Oasis™ Indirect Evaporative Cooling (IEC) systems, Munters specialists can provide comprehensive design support to data center cooling engineers.

Sophisticated design software provides detailed thermal performance and financial predictions, including hourly energy consumption for the full year, based on predictive weather data.

Typical medium to large size data centers require from 0.5 to 50 MW of cooling capacity. The recommended temperature for supply air for computer rooms is 80.6°F (27°C), according to ASHRAE Thermal Guidelines for Data Processing Environments 2009a, making Munters Oasis IEC systems an ideal choice. Market research continues to predict that computer room temperatures will increase to even higher levels, making these indirect evaporative solutions even more cost effective.

Munters Oasis Indirect Evaporative Cooling (IEC) solutions have now been installed in a wide variety of data centers across North America, Europe, Asia, Australia, and New Zealand. These systems circulate the primary air from the white space through heat exchangers which are cooled using a combination of outdoor air movement and evaporation. The indoor and outdoor airstreams never mix, resulting in a minimal requirement for filtration.

Munters has a long history of developing innovative solutions for heat transfer, humidity control, and evaporative processes. One example is the concept of using air-to-air heat exchangers to harness the cooling potential of ambient conditions while retaining a clean and controlled data center environment. This concept called “Indirect Air-Side Economizer” (IASE)  for cooling data centers was pioneered by Munters in 2007 using a polymer tube heat exchanger developed in 1997.

Munters Cooling Technology

The concept of IASE Air Handling Units originated in the mid 1970’s with heat exchangers cooling large DC motors in coal mines. It continued with cooling electrical enclosures for telecom in the 1990’s. By 2007, data center cooling was looking more like process air cooling, making the IASE concept a simple and viable energy efficient solution.

Munters IEC systems are equipped with a polymer tube air-to-air heat exchanger that transfers heat to a separate outdoor airstream. If needed, air and water can be flushed over the exchanger to reject heat. The processed air passing through the exchanger never comes in contact with the water. As a result, no humidity is added to the supply air.

Telecommunications Facilities

Energy consumption, reliability, and maintenance are important factors for critical telecommunication facilities. Thermal loads inside telecom facilities and electronic enclosures must be managed efficiently. Heat is constantly generated in these facilities making this an ideal application for indirect evaporative cooling.

Munters indirect evaporative cooling (IEC) solutions enable telecom customers to free up electrical power for their core equipment. Munters Oasis IEC can even work in the economizer mode during the extreme ambient weather conditions of summer at 100 °F (38 °C ) and 75% RH.

Telecommunication customers have been able to increase the available electrical power by 37% when utilizing Munters IEC systems. This allows telecom customers to install more communication equipment without having to invest in additional expensive power installations.

Munters’ Direct Evaporative solutions include “DataDek Evaporative Pads”, an advanced version of Glas-Dek – the most popular range evaporative cooling pads in the world. The technical properties of DataDek have been specially developed to meet the demanding requirements of modern data centers.

Munters also offers plate heat exchanger systems if water is not available at the site. Additional features at a glance:

  • Excellent retrofitting solutions for Central Office (CO) and Point of Presence (POP) facilities
  • Reliable units designed and manufactured for mission-critical facilities include built-in redundancy for electrical motors: fans, pumps, and compressors
  • Munters’ cooling solutions are suitable for installations from 100 kW to 25+ MW of electrical load (IT)
  • Munters’ systems provide cooling to telecom facilities with minimal energy, making more electrical power available for additional equipment in the white space.
