Munters Indirect Air-Side Economizer (IASE) has the potential to outperform current cooling strategies while offering some key system advantages. With over 35 years of experience in air-to-air heat exchangers and evaporative cooling, Munters advanced cooling systems provide the desired cooling results using significantly less energy than standard air conditioning.

The TelcOasis™ IASE uses an indirect evaporative cooling system to cool the return air. Munters indirect evaporative cooler is constructed of patented polymer tubes, elliptical in shape, and sealed into headers at both ends. The tubes are flexible and shed mineral scale deposits that form during the evaporation process. Water is sprayed over the exterior of the tubes while the warm data center air flows through the inside of the tubes. The data center air never comes in contact with water. Supply fan motors are equipped with variable speed controls allowing the supply airflow from the unit to be capable of matching the airflow of the IT equipment fans. A standard touch screen model is offered to the Telecom and IT industry to cover most central office, point of presence and switch gear/server/computer room applications.

Munters TelcOasis™ units consume less peak power compared to conventional cooling systems, enabling Telecom customers to free up electrical power for their core business. These outdoor units do not occupy valuable indoor white space and can be located on the roof or on the exterior perimeter of the building.

The TelcOasis™ 10k unit is the ideal choice for retrofitting projects as the weight and the footprint were designed to replace conventional R-22 rooftop package units.
