Munters - Data Centre Indirect Evaporative Cooling

IT Cooling - Air Treatment - Condensation Control - De Humidifiers

Munters Data Centre

Keeping intelligent data centres comfortable and operational 24hrs a day is essential. The industry is focused on solutions that reduce energy and carbon emissions associated with data centre operations.

Munters specialist data centre teams offer full assistance to data centre cooling engineers and our Oasis™ Indirect Evaporative Cooling performance program enables financial and thermal performance questions to be answered including energy savings for every hour in the year.

Historically data centre equipment was cooled with standard HVAC air conditioning delivering air at 10°C (55°F). As the cool air passed through the computer equipment it returned to the HVAC unit at 24°C (75°F) to 27°C (80°F) where it cooled to 10°C (55°F) to be redelivered.

Most medium to large sized data centres require 0.5 to 50 MW. The recommended supply air temperature for computer rooms is 27°C (80.6°F) (ASHREA Thermal Guidelines for data processing environments 2009a) which makes demand for Munters Oasis™ Indirect Evaporative Cooler the preferred choice. Market research point towards these temperatures will increase to even higher levels… as decreased temperatures mean added cooling costs.

Data centre operators are rapidly moving towards Munters Oasis™ Indirect Evaporative Coolers which incorporate heat exchangers with outdoor air, to give minimal air filtration and enhanced supply temperatures resulting in data centre pPUE's of less than 1.10
