The unit weight of 150kg and height of 1,000mm makes installation easy. Stacked configuration is also possible, contributing furtherto space savings.Installation space (16 HP)3.56 m 2 → 1.88 m 2RSXYP➧Approx.50 %reductionStacked configuration is possible.3200mmor higherCeiling height)(Floor level)(100-300mm)
