The Desert Refinery is a room in the experimental simulated desert area of the Pyrosphere in Metroid: Other M. It connects from the Environmental Test Floor. The first part of the area is mostly a set of multiple staircases with Heat Bulls, Super Zebesians and Novas in the way. Similar to the Sector Generator Room in the Cryosphere, Samus must Wall Jump from a wall to a spinning turbine covered in Grab Ledges. Samus must then get to a Terminal to activate the door.
