AirTrunk JHB2 (Iskandar Puteri, Johor)
Second AirTrunk hyperscale campus in Malaysia, at Iskandar Puteri, Johor, scalable to more than 270 MW for public cloud and technology customers. AirTrunk says JHB1 and JHB2 together provide more than 420 MW of IT load and a combined investment of over RM9.7 billion (A$3.5 billion). JHB2 will use liquid cooling, and AirTrunk is scoping treated greywater as a recycled water supply. Two different design PUE values are published by AirTrunk (see conflict note).
