Features and Benefits ® Trane 3-D Scroll Compressor Simple Design with 70% Fewer Parts Fewer parts than an equal capacity reciprocating compressor means significant reliability and efficiency benefits. The single orbiting scroll eliminates the need for pistons, connecting rods, wrist pins, and valves. Fewer parts lead to increased reliability. Fewer moving parts, less rotating mass, and less internal friction means greater efficiency than reciprocating compressors. Patented 3-D Scroll Compliance

Application Considerations Self-Contained Equipment Room Construction Options The preferred equipment room wall construction is concrete block. If this is not feasible then a double stud offset wall is suggested (See figure). This removes physical contact that would transmit sound through the equipment room wall to the occupied space. Interweave fiberglass insulation between the wall studs. Use two layers of sheetrock on each side of the wall. Workmanship details are critical to acoustical perfo
