Dryer design for a vehicle wash system

A dryer assembly for a vehicle treatment system, comprising:

• a frame portion having at least one leg portion extending in a vertical direction between a lower end portion for engaging a ground and an upper end portion for being spaced from the ground;
• at least one dryer unit having a housing with an inlet opening and a plurality of nozzles being positioned in parallel relationship with one another and aligned with one another generally in the vertical direction;
• a rotatable impeller disposed in a flow channel in a head portion of the housing, the flow channel having a cut-off segment;
• the rotatable impeller being rotatable about an axis of rotation, the axis of rotation being generally perpendicular to the vertical axis;
• and
• at least one of the plurality of nozzles being disposed above the cut-off segment with respect to the vertical direction and at least one of the plurality of nozzles being disposed below the cut-off segment with respect to the vertical direction;
• wherein a top of the plurality of nozzles is substantially aligned with a top of the head portion in the vertical direction, and wherein the plurality of nozzles are located entirely below the top of the head portion in the vertical direction.

A dryer unit for a vehicle treatment system, comprising:

• a housing having a front side, a rear side, a side portion configured to be disposed adjacent a vehicle treatment area, an upper portion and a lower portion;
• the side portions extending generally in a vertical direction between the upper and lower portions;
• a head portion disposed in the upper portion of the housing, the head portion having an air inlet opening formed therein, and having a top in the vertical direction;
• an impeller disposed in the air inlet opening and configured to rotate about an axis of rotation being generally perpendicular to the vertical direction and to draw air into the housing through the air inlet opening;
• a flow channel formed in the upper head portion around a periphery of the impeller, the flow channel having a cut-off segment where the inner surface of the head portion is closest to a periphery of the impeller;
• and
• at least one nozzle portion being integrally formed with the housing, the at least one nozzle portion being disposed along the side portion substantially from the upper portion to the lower portion of the housing, and wherein the at least one nozzle portion is located above and below the cut-off segment, and entirely below the top of the head portion in the vertical direction;
• and wherein a top of the outlet nozzle portion is substantially aligned with the top of the head portion in the vertical direction.
