Our rotor housings protect the cooling rotor of the air conditioning system and at the same time ensure it operates quietly. With the innovative solution of using two thin sheets rather than one thick sheet, the rotor's acoustics are significantly better without sacrificing precision. We can do this, of course, because we work with correspondingly tight tolerances. This technique does two things: ensures balance and avoids additional steps in the work process. This is how we create the greatest level of comfort at a lower cost.
