The 6500 MXAC top mounted air conditioner is made to be installed on top of a Mtrx cabinet. The top and air conditioner are made of steel. The 6500 MXAC must be ordered using two part numbers. The first specifies the top mounted air conditioner (voltage and cooling capacity); The second specifies the corresponding AC pre-perforated top cover. A robotically poured-in-place gasket ensures a complete and durable seal. The tops are finished with heat fused polyester powder, electro-statistically applied on a phosphatized base (RAL7011).
